What is the correct term for the welding process known as TIG welding?

TIG welding is correctly referred to as Gas Tungsten Arc Welding, commonly abbreviated as GTAW. This process utilizes a non-consumable tungsten electrode to produce the weld. In GTAW, the weld area is protected from atmospheric contamination by an inert shielding gas, which is typically argon or helium.

The use of tungsten as an electrode allows for high-quality welds on thin materials such as aluminum and stainless steel, as it produces a clean and controlled weld bead. Mastery of the GTAW technique is significant for sheet metal work, particularly when precision and aesthetics are critical.

While MIG welding stands for Metal Inert Gas and is a separate process that uses a consumable wire electrode, and SAW refers to Submerged Arc Welding, which is primarily used for thicker materials in a different application, PULSE is not a welding process by itself but could refer to a specialized method or technique used in various welding practices, including certain modes of MIG welding. Understanding these distinctions underscores the importance of proper terminology in the welding field.
