Learn About TIG Welding

Author: mdtread

Welding, as is known by so many, is the routine used for fusing metals. There are various types of welding processes like arc welding, gas welding and resistance welding. TIG, or Tungsten Inert Gas can 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 more amperage which allows for greater thickness of metal to be welded, in between other advantages relating to the purity of the metal, cleaning etc. Welding with TIG involves 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 multipurpose 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 despite whether AC or DC electric current is used. The three most common problems encountered by the operator in TIG welding are erratic arc, high electrode consumption and porosity of the weld.
Lack of fusion, leaks from hoses carrying 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.
