What is one alternate name for GTAW?

GTAW, or Gas Tungsten Arc Welding, is indeed also known as Tungsten Inert Gas welding, commonly abbreviated as TIG. This term is derived from the fact that tungsten is used as the electrode in the process, and it employs an inert gas, usually argon or helium, to shield the weld area from atmospheric contamination. The designation "TIG" effectively captures the essence of the process, focusing on the crucial components: the tungsten electrode and the inert gas protection.

In contrast, the other welding processes listed have their own specific characteristics and do not relate to GTAW. For instance, Metal Inert Gas (MIG) welding utilizes a wire feed as an electrode rather than a separate tungsten electrode and employs a different shielding gas technique. Flux-Cored Arc Welding (FCAW) uses a tubular wire filled with flux, which isn't applicable to the GTAW method. Submerged Arc Welding (SAW) operates under a blanket of granulated flux, which also diverges fundamentally from the TIG process. Therefore, recognizing synonymous terms in welding helps clarify the principles and techniques associated with each method.
