Which arc welding process is also referred to as TIG welding?

TIG welding is commonly known as gas tungsten arc welding. This process uses a non-consumable tungsten electrode to produce the weld, and the arc is established between the tungsten electrode and the workpiece. The use of an inert gas, typically argon or helium, protects the welding area from contamination by the atmosphere, thus providing a clean and high-quality weld.

Gas tungsten arc welding is especially favored for its ability to produce precise, high-quality welds on thin materials and its versatility with different metals, including stainless steel, aluminum, and copper. The level of control it offers over the heat input makes it particularly suitable for applications where high-quality standards are paramount.
