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.

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.

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.

Laser plastic welding

Today, laser-plastic-welding is replacing other joining techniques such as gluing & ultrasonic welding in many manufacturing & industrial fields. So the modern joining process for plastics is highly flexible & free of particles & solvents, & it provides high strength connections without marking or damaging the work surface. So plastic laser welding is invaluable when precise control or accuracy is needed to protect for the vital internal components, this can be used to successfully weld-plastics even when faced with challenging geometries.

With this illustration, you can see the process of laser plastic welding at work

1: Laser beam 

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.
