TIG (Tungsten Inert Gas) welding, also known as “Gas Tungsten Arc Welding” (GTAW), is an arc welding process that uses a non-consumable tungsten electrode to produce the weld.
Like MIG welding, a shielding gas is used. The weld area and electrode is protected from oxidation or other atmospheric contamination by an inert shielding gas like argon or helium. A filler metal is normally used, although some welds do not require it.
GTAW is most commonly used to weld thin sections of stainless steel and nonferrous metals such as aluminum, magnesium and copper alloys. The process grants the user greater control over the weld than competing processes such as Shielded Metal Arc Welding (SMAW) and Gas Metal Arc Welding(GMAW), allowing for stronger, higher quality welds.
The caveat is that GTAW is comparatively more complex and difficult to master. It is also significantly slower than most other welding techniques.
The metal most frequently associated with this process is aluminum, especially with metals of a smaller thickness. Many other processes, of course, can join together aluminum parts, but in the lighter gauges the preferred process is the TIG welder.
The TIG welders we carry are ideal for maintenance, fabrication, automotive, piping, brewery work and more.
