What is TIG weld?

TIG (Tungsten Inert Gas) welding, also known as GTAW (Gas Tungsten Arc Welding), is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area is shielded from atmospheric contamination by an inert shielding gas (argon or helium). It is commonly used for welding thin sections of stainless steel, aluminum, magnesium, and copper alloys due to its precision and ability to create high-quality welds.
