Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld.  The weld area is protected from atmospheric contamination by an inert shielding gas, usually argon or helium.  GTAW is commonly used to weld thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys.

The GTAW process provides the welder with maximum control over the weld puddle, allowing them to produce high quality and precisely controlled welds.  The electrode, weld puddle, and base material are all visible during welding, unlike some other welding processes.  In addition, GTAW only deposits filler metal when needed, minimizing distortion and spatter.  It can be used for both manual welding and mechanized welding.

GTAW produces clean, high-quality welds and is commonly used for welding critical components and applications where strength and appearance are important.  Contact the experts at Microtech Welding to learn more about GTAW and how it can benefit your welding projects.
