Advantages of Laser Welding Over Traditional Welding Methods

Advantages of Laser Welding Over Traditional Welding Methods

Since the introduction of the first laser in the early decade of the 1960, this unique technology has experienced a fast-paced evolution. In modern times, light amplification technology has been utilized throughout a variety of applications, from manufacturing to military armaments. However, thanks to the persistent progression and comprehensible research of laser technology, they are more efficient, powerful, smaller and economic than in previous generations.

One industry that has benefited greatly from the introduction of laser technology is metal welding. During the operational process known as laser welding, a light beam is amplified providing a focused and strong origin of heat that is used to connect multiple pieces of metal. The high energy density of the laser allows the surface of the material to briefly turn into a liquid state allowing for the pieces to be bonded. This innovative welding process allows for a much more rapid fabrication time and output when paralleled to alternative welding methods. Because of the high welding rates, it works particularly well for large volume applications.

When compared to traditional welding techniques such as arc welding, laser welding has some similarities however it also has its own unique characteristics. The most prominent dissimilarity between two welding processes is the manner in which the energy is reallocated. Like gas metal arc welding, laser welding is process based on fusion performed under inert cover gas. However it provides a much faster welding rate by a substantial margin in addition to generating very little, if any, distortion to the metal piece. Furthermore laser welding does not require the work piece to make a full electrical circuit, unlike gas metal arc welding or electron beam welding. This style of welding not only provides a technical improvement and gain, it also cost-effective benefit over similar techniques. For example, due to the vacuum chamber requirement of electron beam welding, equipment and operation costs can generally be higher compared to laser welding.

Several more advantages include on-line processing, sorter cycles and higher uptimes, and the fact that this type of welding can be used to weld magnetic materials. Because this welding procedure can be transmitted in pulses, meaning that the minimal amount of heat is added is another benefit. The continuous pulsing of the beam allows the metal to cool between each pulse of heat. As a result, there is a very small heat affected zone. This makes laser welding an ideal technique for thin metals or when welding is required near electronics. The small contribution of the energy in conjunction with the visual procedure results in more possibilities when it comes to tooling and materials.

Welding Jobs: Got Gas? (As Long As It Is Natural You Can Get Rich Making The Most of It)

Welding Jobs: Got Gas? (As Long As It Is Natural You Can Get Rich Making The Most of It)

Most people don’t think of welding and natural gas at the same time they think of wealth building.

These two elements (welding and natural gas) will soon converge into an economic power house for any entrepreneur with vision. Find out why.

Why Welding? The metal shop in high school closed long ago – along with auto shop and wood shop. For decades, most welders started out in high school metal shop – and now for two decades metal shop has been considered, “mental slop” by the elites who only see “intelligent pursuits” as those involving computers and other tech.

Sadly, this has caused a huge and growing shortage of welders and other trades.

Just as the powers that caused “computer class” to replace “metal shop” – the powers that rule the welding industry don’t understand their own industry well enough to update the focus of welding. This is because the welding game has changed.

“Tradition” can be a train wreck – and that is the case with welding education.

Welding education today is like a re-run of the movie, “Back To The Future.” It is 1950 all over again when you step into a junior college welding class. Hours and days are spent on book learning. Hours and days are spent on learning techniques and processes the average welder will never use.

Yes, one or two things taught in structural welding classes are applicable in the job market – enough to get the average welder coming out of a year of more of education a job welding for $10 to $15. Last time I checked you can make that much cleaning windows…

Where is the Entrepreneurial Opportunity in welding?

Pipe welding covers a lot of ground – there is carbon steel pipe, aluminum pipe and stainless pipe. Each category has a variety of types, sizes and applications. Welding any and all of them produces excellent incomes. Individuals can make $75,000 to $150,000 a year without a welding truck (called a rig).

Welders with their own rig are making up to $300,000 a year.

Welders who own 3 rigs and weld themselves while managing other welders can and do top $500,000 with a relatively small business organization.

Where does natural gas come into this?

The United States has $178 Trillion in natural gas and oil on U.S. Federal Lands alone! We are not tapping that gas now – the vast majority of the wells which have recently caused the USA to become the largest producer of oil and gas on the globe are located on private lands. The reserves of oil and gas on private lands is beyond belief – and no longer disputed. We will be swimming in oil and gas for generations to come.

Did you think solar and wind would win the day?

Much like propaganda in any country at any time in history, wind and solar is NOT what most people think. The power production is minuscule. When your neighbor gets solar on their house – you paid for a large portion of that system because of large federal and state subsidies. Solar and wind (after all the noise about them) still make up less than 5% of all power production – and a very high price has been paid by all us for it.

On the contrary, oil gas operate in a pure, true market environment.

The oil and gas industry will not be shut down because the government “pulls the plug” on subsidies. AND natural gas is a very low emission, low polluting energy source!

My brother held 11 patents for co-generation technology in the 1980s. He built a large business because the market was subsidized. When the subsidies were stopped, the business stopped. The same thing will soon happen for solar and wind.

Oil and gas produce huge amounts of energy and won’t be replaced for 100 years.

Natural gas usage will increase dramatically in the coming years. We will soon see over the road diesel trucks repowered with natural gas (for example). Honda has made a natural gas Civic for many years. Police cars, taxis and city buses are powered by natural gas right now.

Where will people fill up?

There is a small but growing number of natural gas stations across America. And many homes in America run on natural gas. Filling stations which can be installed at residential locations are on the market now. Would you like to fill up your car at home for $3? You can! The Russians are working on airplanes powered by natural gas. The possibilities are endless – and many will be reality sooner than you think. And yes, you could build a business just installing natural gas filling stations.

Conclusions:

If you can think of a “dream industry” to work in, what would it be? If you want one that will have expotential growth over the next 20 years think oil and gas. Unlike the growth of hamburger stands in the 60s, oil and gas jobs pay very well. Walk into Midland Texas with no experience and get a job as a “roustabout” (a common laborer) and you’ll make $40,000 to $50,000 – and that is the bottom of the ladder.

The best part about pipe and pipe welding:

The oil and gas industry is the biggest employer of pipe welders. The growth of natural gas utilization means enormous amounts of pipe must be welded. The American Welding Society or AWS sets the standards for welding. Way back in 2007 they said, “The average rig pipe welder in Alberta Canada makes $330,000 a year.”

I recently spoke to a welder who went one step further contracting repairs with a refinery in 2013. He made $400,000 in 2013.

What is the bottom line?

Welding and the oil (and particularly natural gas) present an exciting fast growing opportunity that can make anyone with some moxy and get up go rich in the coming years – regardless of the condition of the rest of the economy. Is that why North Dakota has 2.6% unemployment? Did you know Midland, TX has 2% unemployment? Did you know that 5% unemployment is considered “Full Employment” because 5% of the work force should not be working? These numbers are stunning – they are incredible.

The USA must go through another deep recession. to wash out the debt that is keeping the general economy down. Many areas of business we now think of as “bullet proof” will shrink or disappear. The DOW will probably sink to 5,000 by 2016 or 2017 – but naturals gas will stay strong which means pipe welding jobs will be plentiful, even during the next recession.

Welding Jobs: Why Welding Sucks (And What You Can Do About It)

Welding Jobs: Why Welding Sucks (And What You Can Do About It)

If you can weld now or want to weld, is that a big deal? Yes and no.

Welding can be a very difficult skill to acquire and take years – or an afternoon (or a few days) at home. The question is, are you making any stinking money at it? Yes, you love to weld (I do to). Why are some welders rolling in money and others are so broke it isn’t funny? Get answers, NOW.

Let’s see, anyone can pop into Home Depot and buy a little Lincoln flux core welder and learn to weld in an afternoon or a day or two? Yes.

The welder I’m referring to is about the size of carry-on luggage and plugs into any 120 volt socket. Follow the instruction booklet (always reading the safety portion and applying all of it – please) and that person can be running a decent bead on the flat, just like that. Really – in a few hours of paying attention you can be running decent beads with good penetration.

The REAL question is, can you take that skill and make money?

Think about it – you can read this article, hop in the car, buy the welder, plug it in and weld for a few hours and have a “skill” at some level. What does that make you? It makes you a person with a very limited skill, but a skill none-the-less.

When I was 13 I welded up the exhaust on one of my many cars (I flipped cars for profit from age 11 to 22). Welding came in handy on older cars from the early 60s and even the early 50s because they were “heavy metal.” I wasn’t a great welder at that point, but being able to weld could make the difference – it allowed me to do repairs and “add value” to a car. Instead of flipping burgers at Mickey Ds, I was able to always have plenty of money.

Later, at age 19 and just out high school, I built gates – nice gates which look great today, 40 years later. I was self-educated in welding and I highly recommend it (welding self education and self education for almost any skill).

So why is the title of this article: “Welding Sucks?” Well, for most welders, it sucks. It is not fun when you get stuck with a limited skill in a factory not making enough money and acting like a robot all day long.

What can you do to make welding fun again?

When you first started welding, it was fun. You didn’t need to make money at it right away. AND everyone around you told you there would be a “good job” waiting for you when you got good at welding – so you kept at it.

Maybe you went through one or two years of welding education – and then the truth hit you like a brick wall. You found out that no one wanted to pay you big money for welding…

What is the secret?

What is the well guarded secret no one seems to tell welders? It is marketing. If you can MARKET your skill – no matter what that skill is – if your skill is welding or washing windows, if you can MARKET that skill, you will make all the money you and your family need. If you can’t, you won’t. That is when welding is NOT fun – when you can’t make good money at it.

What can you do about it?

Step # 1:

Stop thinking “Job.” J-O-B stands for “Just Over Broke.” If you want to live your life that way, get a job or keep the one you have.

What is the difference between a window washer working for someone else and window washer making great money for 28 years?

I met Suzy the other day. Suzy lives in a waterfront home with a dock. Suzy has a new GMC 4 door truck (very nice). Suzy no longer bothers to advertise her business. Suzy has been cleaning windows as an independent window cleaner for 28 years. She doesn’t need to advertise.

Why am I telling you about a window cleaner?

Suzy became an INDEPENDENT window cleaner 28 years ago. She employs 3 window cleaners and pays each of them $10 an hour. Suzy collects $20 an hour for every hour her window cleaners work. Suzy also runs a fourth truck herself. Add it up – Suzy makes $30 an hour from her workers and she makes another $20 an hour for the hours she works. Suzy makes $100,000 a year washing windows. This is called “Capitalism.”

Why do you need to be a Capitalist?

We live in a capitalist society. This means that if you weld now for $10 an hour, you can weld as an independent welder for $30 an hour (or more) simply by being “in business” instead of being a “a working drone” for someone else. Is that hard to believe? Believe it – it is simply TRUE!

$30 an hour is cheap for a welder.

I am telling you – you can make $30 an hour next week with minimum welding skills, if you understand and apply basic marketing skills.

What about immigrants? Meet Tom:

Tom (not his Viet Namese name) is one of the nicest people I have even encountered. Tom is 60. In 1980 Tom was one of 25 people crowded on a small fishing boat pulling away from Communist Viet Nam and headed for Hong Kong – escaping at the risk of his life – to a new life of freedom.

The captain of the boat put a gun by the compass. It screwed up the compass. They were lost at sea. They ran out of gas. They ran out of food. The seas grew wild. Tom was pretty sure they were all going to die.

They saw a ship in the distance. They waved their coats. They were given food and gas told which way to go to reach Hong Kong. Tom made it to the U.S. Tom was totally and completely broke – and he spoke no English.

Working an assortment of jobs 15 hours a day, Tom saved money. He met Lany and they saved. They opened a nail salon and then another. Today, Tom and Lany are comfortable in America. Their home is nearly paid for and they have a large retirement. Why? Tom and Lany worked hard – and understood marketing. And yes, they had a skill – they started by becoming licensed to do nails. Can you see – “doing nails” was only part of their of their success – actually the small part.

What has this got to do with welding?

Everything! However, welding has so many advantages over window cleaning and doing nails! You can start right now and be an entry level welder, working for yourself a week from now, if that is what you want. Unlike window cleaning and nails, you can advance your welding skills as you go – teaching yourself from home – until your welding skills are worth (are you sitting down) $100 an hour.

Don’t run over to Home Depot and buy a welder (yet).

If you buy the right welder used and do the right things with marketing, you can be in business and working all you want in 2 to 3 weeks. How? It requires mastering a few marketing basics – and hard work – but if a Viet Nam boat person who could not speak English can do it, you can too.

Conclusion:

You success has nothing to do with money or the economy. It has to do with you believing in you. From there, you only need to pay attention to what really matters.

What should you do next?

Look – are you a person? I am too! I am a welding inspector who now writes. I also have made millions in small business. So what? Well, I’m offering 20 minutes on the phone or in email with me – and I won’t sell you anything – it is all free. It will be 20 minutes that could change your LIFE! It is FREE! I won’t bite – promise!

Gas Welding Technology

Gas Welding Technology

Gas welding is a process in which a fuel gas such as acetylene, hydrogen, natural gas, etc. is mixed with oxygen in proper proportion to burn to get a flame which, if found adequate for melting a given metal, can be used for fusing and joining different parts of it. The process is very versatile because it can weld most of the commonly employed engineering metals and their alloys. Brief description of the well known variants in this class of welding processes follows.

Oxy-Acetylene Welding

This is the best known gas welding process and was successfully employed first time in 1903 when a welding torch for the purpose was developed. In this process acetylene (C2H2) is mixed with oxygen in the welding torch and is then burnt at the torch tip to give a flame with a temperature of about 3300oC which can melt most of the ferrous and non-ferrous metals in common use.

Oxygen and acetylene are easily available in cylinders at temperature of about 1500 N/cm2 and 170 N/cm2 respectively. These are connected to the welding torch through hoses and are mixed and burnt to get different types of flames viz., neutral, oxidizing and carburising. The natural of the flame depends upon the ratio of the two gases. The neutral flame is most often used for the welding of most of the materials like low carbon steels, cast steel, cast iron, etc. The oxidising flame has higher proportion of oxygen than acetylene and is used for welding of manganese steel, brass and bronze whereas the carburising flame has higher proportion of acetylene in it and is used for welding aluminium, nickel, etc.

It is quite common to use filler material with gas welding through if need be, the process can be used without filler as well. Commercially, oxy-acetylene process is very widely used for welding of ferrous and non ferrous metals particularly for welding thin sections upto 6 mm. A large percent of the repair work is also done by oxy-acetylene welding.

Typical applications of the process include welding of root run in pipe and other multi-run welds,, light fabrications like ventilation and air-conditioning ducts and motor vehicle repairs.

Oxy-Acetylene Pressure Welding

In normal or non-pressure oxy-acetylene welding process no use of pressure is made to accomplish a joint. However, in slight variant of the usual process, the prices to be joined are heated by oxy-acetylene flame burner and brought to the pasty or semi-solid state. Axial pressure is then applied to achieve a joint which is normally of an upset weld type. No melting of the parts being welded is involved hence it is a solid-state welding process and is also called ‘Hot Pressure Welding’ or simply as ‘Gas Pressure welding’.

The ends of the work piece to be welded are prepared by cutting and cleaning. The pieces are then held in clamps under an axial pressure of about 3.5 to 7.0 n/mm2 for mild steel. An oxy-acetylene torch or a heating head of the desired configuration is made to surround the abutting (or projecting) ends and heated uniformly to about 1200oC. During the heating cycle the pressure is increased to the desired lengths of the two pieces. This is also prevents the possibility of local overheating or superficial melting.

Oxy-acetylene pressure welding can be used to weld all commercial metals which can be butt welded, however, presently it is used mainly to weld carbon and low alloy steels in the form of rods, rails, pipes, tubes, narrow strips, and structural shapes. In general, those materials which absorb their own oxides at elevated temperature, e.g. low carbon steels, are more easily welded by this process. However, this process finds only a limited use in the industry because it is uneconomical to use it for one-off work as well as due to lack of uniformity and consistency of components produced by the process.

Basic Function of Semiautomatic MIG Welding Machine

Basic Function of Semiautomatic MIG Welding Machine

MIG WELDING MACHINE

Functioning a satisfactory MIG Welding process requires more than just semi operative skill. The setup, voltage, current, electrode extension, and welding angle, as well as other factors, can dramatically affect the weld produced. The very best welding conditions are those that will allow a welder to produce the largest quantity of successful welds in the shortest period of the time with the highest productivity. Because these are semiautomatic or automatic processes, increase productivity may require only that the welder increase the travel speed and current.

MIG WELDING MACHINE SETUP

In complete MIG welding machine setup, we require GMAW or MIG power source, welding torch, wire feeder unit, shielding gas supply, gas regulator, flow meter & heater, shielding gas hoses and MIG wire.

If the shielding gas supply is a cylinder, it must be chained securely in place before the valve protection cap is removed. Standing to one side of the cylinder, quickly cracked the valve to blow out any dirt in the valve before the flowmeter regulator is attached.

Install the reel of electrode (welding wire) on the holder and secure it. B sure the power is off before attaching the welding cables. The electrode and work leads should be attached to the proper terminals. The electrode lead should be attached to electrode or positive (+). If necessary, it is also attached to the power cable part of the gun lead. The work lead should be attached to work negative (-).

CHECK WIRE FEEDER UNIT

Using the MIG Welding Machine that was properly assembled, we need to turn the machine on and thread the electrode wire through the system. Switch on the power and check the gun switch circuit by depressing the switch. The power source relay, feeder relays, gas solenoid and wire feeder motor should all active.

Cut the end of the electrode wire free. Hold it tightly so that it does not unwind. The wire has a natural curve that is known as its cast. The cast is measured by the diameter of the circle that the wire would make if it were loosely laid on a flat surface.

Note: With the wire feeder running, adjust the feed roller compression so that the wire reel can be stopped easily by a slightly pressure. Too light a roller pressure will cause the wire to feed electrically. Too high a pressure can turn a minor problem into a major disaster.

GAS DENSITY AND FLOW RATES

Density is the chief determinant of how effective a gas is for arc shielding. The lower the density of a gas the higher will be the flow rate required for equal arc protection. Flow rates, however, are not in proportion to the densities. Helium, with about one-tenth the density of argon, requires only twice the flow for equal protection.

ARC VOLTAGE AND AMPERE CHARACTERISTICS

The arc-voltage and amperage characteristics of MIG Welding are different form most other welding processes. The voltage is set on the welder, and the amperage is set by changing the wire feed speed. At any one voltage setting the amperage required to melt the wire must change as it is fed into the weld. It requires more amperage to melt the wire the faster it is fed, and less the slower it is fed.

ELECTRODE EXTENSION

Because of the constant-potential (CP) power supply, the welding current will change as the distance between the contact tube and the work changes. Although this change is slight, it is enough to affect the weld being produced. The longer the electrode extension the greater the resistance to the welding current flowing through the small welding wire.

With a standard MIG Welding CC power supply this would also reduce the arc voltage, but with a CP power supply the voltage remains constant and the amperage increases. If the electrode extension is shortened, the welding current decreases.

WELDING GUN ANGLE

The term welding gun angle refers to the angle between the MIG Welding gun and the work as it relates to the direction of travel. Slight changes in the welding gun angle can be used to control the weld as the groove spacing changes. A narrow gap may require more penetration, but as the gap spacing increases a weld with less penetration may be required. Changing the electrode extension and welding gun angle at the same time can result in a quality weld being made less than ideal conditions.

Welding Types and Welding Rods

Welding Types and Welding Rods

Welding is the process of heating two pieces of metal so that they join and form a firm joint. To do this, one needs a high degree of skill and technology. There are different ways of welding; some require machinery and advanced technology, including lasers, beams, etc. Welders work with metals, alloys and materials.

Oxy-Acetylene Welding is a welding process that requires the use of a special welding torch to mix oxygen and acetylene gases and produce a small flame of up to 6,300 degrees. This process is widely used to manufacture wrought iron gates and fences. This type of binding is normally used in industries that work with copper pipes, including brass wear plates and brass rods.

Gas Cutting Using Oxy-Acetylene

Most of the gas torches have a lever style valve that facilitates an extra burst of oxygen through the cutting torch to the work that has been heated to melting point. This shot of oxygen burns away the parent metal with high force and speed, thus producing a small narrow cut in the metal. This way, welders can cut easily, either manually or by machines. Manual gas cutting can cut metals of 1/16 of an inch and up to two inches, while profile cutting can cut steel up to a thickness of four inches.

TIG welding

Tungsen welding or TIG welding uses a non-consumable tungsten electrode to create the weld. The weld area is protected by an inert shielding gas and a filler metal is normally used. This type of welding is usually used to thin sections of stainless steel and metals like aluminum, copper and magnesium.

Plasma arc welding

In plasma arc welding, the electric arc is formed between an electrode and the work piece. The process is similar to TIG welding.

Laser Beam welding

Laser Beam welding is a meld technique where multiple pieces of metal are joined through the use of a laser. This type of welding is often used in high volume applications, such as in the automotive industry.

Welding rods

Welding rods of good quality should be bought, so that the welding result is better. Welding rods are used to place additional metal to the weld. Hence, it needs to suit the parental metal. Welding wire and oxy-acetylene rods are mostly made of Norway steel. Choosing the right welding rod is important as it helps to determine the success of a weld and the strength of a joint. If you choose the wrong rod, it can produce a meld that is either too hard or brittle.

TIG Welding Revisited

TIG Welding Revisited

Welding, as is known by so many, is the process used for fusing metals. There are distinctive types of welding processes like arc welding, gas welding and resistance welding. TIG, or Tungsten Inert Gas may be described as a type of gas metal arc welding. Instead of flux coated electrodes a gas shield is used to purge oxygen from the weld path. Bare wire is fed into the gas shield area while the tungsten electrode burns the bare wire fusing the bare wire to the parent metal.

One of the major advantages to a TIG welder is higher amperage which allows for greater thickness of metal to be welded, amongst other advantages relating to the purity of the metal, cleaning etc. Welding with TIG demands the work pieces to be prepped an cleaned properly. Let’s look at the advantages of Using TIG:

1. TIG is qualified as being a better quality weld

2. The skill sets used to produce that type of weld are higher on the part of the welder

3. The process of TIG usually uses more than one process

4. The weld is usually cleaner allowing for higher quality of welding overall

5. TIG welding is a most respected art category

6. The variation of types of metal that can be fused are greater

7. Can lead to a stronger overall weld composite

These just mention a few. Learning to TIG weld can be challenging but it is a most beneficial way to go about the weld. TIG welding is considered as the most flexible type of welding as it can blend all conventional metals like Carbon and low alloy steels, stainless steel, nickel alloys, aluminum, magnesium, titanium, cobalt, and copper alloys. Once the commitment is made to use this great process there must be an insight into areas of concern that may lead to complications with this type of welding as well.

There should be constant voltage no matter whether AC or DC electric current is used. The three most common hassles encountered by the operator in TIG welding are erratic arc, high electrode consumption and porosity of the weld.

Lack of fusion, leaks from hoses transporting the shield gas (that draw air into the hose), weld puddle turbulence, contamination of metals form improper cleaning, and porosity (or gas pockets) are some areas the TIG welder should concern himself/herself with.|Improper fusion, faults in the connections and hoses, puddle turbulence, contaminants of metals to be welded, or porosity of the weld are places the TIG welder should concern himself with in this process.

There is a middle of the road area for gas flow to the TIG gun while the weld is in progress. Usually around ten to twenty five cubic feet per hour is normal. I have been in windy spots before and had to boost up the gas coverage on my rig to keep the shield from being blow away from external forces. When you suffer a loss of your gas shield you get weld breakdown. With that said I think the best gauge to purchase is the style of gas gauge that will let the TIG welder really dial up high settings if needed. Your average flow meter will not allow for maximum range at times. It’s best to purchase one designed like an oxygen regulator instead of the typical argon meter.

Be mindful of the types of gas lenses being used and what type of TIG gun you will use as well.

You know there is just a wealth of information to be considered in such a tremendous topic like welding of this nature. I would like to cover the actual weld actions too but time won’t afford me the space to do it here.

For more information concerning the actual welding process and the dos and don’t of TIG Welding please visit: [http://www.thewelderslens.com] and view the weld while in progress.

Most Commonly Used Equipment in the Welding Industry

Most Commonly Used Equipment in the Welding Industry

Welding machines are useful for a number of joining processes. This includes arc welding, resistance brazing, laser soldering, electronic beam soldering, orbital fusing, and more. Each type of machine features different devices that include power sources, monitors, and controllers for brazing, soldering, and welding.

MIG Welding

One of the most versatile and common types of welding machines are metal inert gas or MIG welding machines. They are useful in home workshops and industries for welding different metals such as steel, stainless steel and aluminum. This is a process in which a continuous electrode and shielding gas is fed through a MIG torch or welding gun. Carbon dioxide gas is commonly used for general purpose welding since it’s cost-effective and creates good welds. The voltage, amperage and speed of electrodes and shielding gas through the welder could be adjusted. In addition, the flow of gas can also be controlled through a flow meter while the tension on the welding wire is variable as well.

TIG Welding

TIG or Tungsten inert gas welding machines are useful in welding thinner sections of stainless steel and non-ferrous metals such as copper alloys, magnesium, and aluminum. The process involves a tungsten electrode that delivers the current to the soldering arc, a shielding gas such as argon to protect the weld area from contamination, and a filler metal. TIG welding machines offer the operator greater control when compared with MIG welding. These machines are available with DC or direct current and AC/DC alternating current, direct current which is useful for fusing ferrous types of metals and both ferrous and non-ferrous types. TIG welds are clean without the buildup of sparks and fumes, which makes it ideal for welding metal artwork. It is also used to weld aluminum cycle and motorcycle frames and food processing equipment.

Arc Welding

Arc welding or stick welding machines use a power supply to form an electric arc between an electrode and base material that melts the metals at the fuse point. Either alternating or direct current could be used. The electrode is made from a material compatible with the base material that needs welding. It’s covered with flux to produce carbon dioxide gas to prevent oxidation and contamination. Arc welders are available in two types. Alternating current welders are air-cooled or oil cooled while direct current welders uses an air cooling system. Inverter welders are the most common type of DC arc welders. While arc welding is generally limited to ferrous metals, it is also possible to weld cast iron, copper, nickel, and other non-ferrous metals. Therefore, arc welders are useful for a number of applications in repair work and construction.

Welding equipment comes in a variety of shapes and sizes ranging from small welders for home use to industrial machines used in specialized industries such as automotive and construction. Mig, Tig, arc and spot welding machines are the common types used today.

A Handful of Main Reasons Why Underwater Welding Is a Very Good Occupation

A Handful of Main Reasons Why Underwater Welding Is a Very Good Occupation

Under the sea welding, or hyperbaric welding, involves welding under the sea, generally underneath grand challenges and tough situations. Oceanic welding is often executed to mend boats, underwater pipelines, commercial fuel platforms, along with other vessels that could be completely, in addition to somewhat under the sea.

There are a couple of types of oceanic welding: Dry as well as moist. Dry sea welding is going to be performed inside of a chamber which is packed with a gasoline mix and after that sealed across the vessel, platform or else additional under the sea form which is in the process of being welded. Moist oceanic welding is done away from a chamber, inside the water.

Is marine welding an excellent professional job? Without a doubt it truly is! Listed below are the highest reasons underwater welding is a superb career, and can often be a an exceptional career switch for you.

Under the sea welding keeps you in fantastic shape. Granted, most likely not the very first thing many individuals remember when deciding upon a profession, but, seeing that marine welding usually takes optimum physical shape, a new career in under the sea welding is an excellent way for you to make sure your body is at its optimal condition.

Marine welding could possibly be tireless on the physical body, therefore it’s crucial for welders to preserve their bodies in top notch physical condition making sure that they can not only undertake the scuba aspect of a typical gig, but still have the ability to complete accurate welding guidelines also.

The income for the marine welder is in fact exceptional. Naturally, what a number of people do consider when choosing a career might be the wage. Marine welders could make efficient hard earned money. The very beginning salary for an excellent sea welder is generally just about one hundred thousand dollars a year, many welders yield $200,000 or even much more! Welders which are willing to move or who will complete urgent welding assignments have the ability to earn a superior income and land jobs that can compensate above the normal marine welding work.

Sea welders could accept expensive extras at work. Because of the negative aspects involved with some aspects associated with oceanic welding, for example welding within elevated depths, welders typically are given bonuses which actually rely on the volume of danger at a particular undertaking. A standard promotion for a lot of welders depends upon exactly how far they need to dive to perform their work. A welder who has to a dive, for example, 100 ft under the sea will frequently receive an incentive of between a hundred dollars to two hundred bucks each and every hour above their current conventional pay.

The career prospect concerning underwater welding is optimistic. The very industries which normally train more marine welders are simply improving in size and recognition through the years. For instance, ships, leisure and otherwise are more accepted now inside the coastline, which implies you will see greater of a desire for oceanic welders in the future. This is also true for anyone of the many companies who take on marine welders. Many roles do not possess this kind of great benefits! Underwater welding adds the two fantastic hobbies. Scuba diving is a well-liked action for many people. It could possibly be comforting, a lot of fun and fascinating being underwater for a specified length of time. And also welding is work which requires excellent skill in addition to soundness. Underwater welding includes the past time of scuba diving together with the tactic of welding to create an intriguing and fruitful profession.

Laser cladding with wire

In this process, and the laser beam melts the wire and the base metal, so the melt bonds permanently & resolidifies until a small rise remains. And when the individual welds overlap-precisely, so the desired shape is applied bit by bit.

Laser-cladding with wire is used for the repair of components & functionalizing of surfaces. So this process is particularly economical, clean, and rework is limited to a minimum. And various welding wires are available as filler materials. So this makes it possible to apply material of the same type / to create functional layers according to the requirements for the coating.

Laser cladding with powder

Whether it is for design changes or repairs, so laser-cladding with powder upgrades surfaces as if they were cast from one customized, and industrial mold.

With laser-cladding with powder, so a filler metal powder coating is welded onto an existing component with a laser. And a professional looking layer, without pores or cracks & with little mixing & a small heat affected zone, and results.

This additive manufacturing process gives the components higher strength & increases the load capacity. And thanks to laser cladding with powder, repair instead becomes more cost effective, because as worn components can be renewed-exactly at the stressed parts.

Laser cladding with a powder-coating is not only a way to save money, and but it is also an excellent way to save time that would otherwise be spent manufacturing replacements. And the remaining material volume from this form of metal cladding shows no deformation & can keep its original properties. And through the use of metal cladding with lasers & a powder coating, components can be returned to operation quickly.

2: Transparent plastic 

3: Absorbed plastic 

4: Diffusion zone 

5: Joining pressure

Laser welding plastics utilizing the laser transmission welding-method joins two thermoplastic plastics, so a transparent plastic & an absorbing joining partner. And the laser beam penetrates the upper, laser transparent component and melts the lower, so laser absorbing component, and which then bonds with the transparent plastic. So when done properly, this creates a leak free, and secure weld.

And with this type of overlapping welding, and the weld is generated on the inside of the component without the release of particles. So it creates a nearly invisible, optically high quality weld with opaque components. And the local heat input with the laser has a minimal impact on the components, welds can be created even in the immediate vicinity of electronic-components. So because laser plastic welding creates a weld without the need for solvents, it reduces industrial waste & saves on cost, so making it a green solution for manufacturers.

There are four main techniques used in laser plastic-welding

  • Contour welding: Used for welding three dimensional / large parts, contour welding moves the laser in a single pass along the welding joint.
  • Mask welding: Laser welding plastic with this method utilizes a wide beam that moves over the entire surface being welded, with a shield protecting areas where welding is not desired.
  • Quasi-simultaneous welding: This technique utilizes a small beam that makes several passes over the welding joint.
  • Simultaneous welding: Multiple beams pass simultaneously over the welding joint.

For more than 20 years, OR Laser has been at the vanguard of laser technology and innovation. Our plastic-welding services and equipment are industry-tested, perfect for any professional need, and among the best available for sale today.
