**Gas Tungsten Arc Welding (GTAW)**

What is Gas Tungsten Arc Welding (GTAW)?

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 (argon or helium), and a filler metal is typically used, though some welds, known as autogenous welds, do not require it. GTAW is commonly used for welding thin sections of stainless steel, aluminum, magnesium, and copper alloys, where high quality and precision are required. It is also frequently used in applications where precise heat control is needed, such as in the aerospace, automotive, and nuclear industries.
