What alternative names are used for the gas tungsten arc welding process?

The gas tungsten arc welding process is commonly referred to by several alternative names that emphasize different aspects of the technique. The names TIG, Heliarc, and tungsten inert gas distinctly represent the same process:

• TIG stands for Tungsten Inert Gas, which highlights the use of a non-consumable tungsten electrode and inert shielding gas, typically argon or helium, to protect the weld area from contamination.

• Heliarc, a term developed by the original company that marketed this welding process, also refers to its use of helium as the shielding gas, although argon has become more prevalent due to its effectiveness and lower cost.

• Tungsten Inert Gas further describes the fundamental components of the process: tungsten electrodes and inert gas shielding.

These names reflect the technical nature and attributes associated with GTAW, making them widely accepted in both industry and training contexts. In contrast, the other options refer to welding processes that either do not involve tungsten or use different welding principles altogether, providing no relevant alternative names for the gas tungsten arc welding process.
