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.
