GTAW is also referred to as TIG or Heliarc. Which term is another name for this process?

Explanation:
GTAW is the process that uses a non‑consumable tungsten electrode with an inert shielding gas to produce precise welds. It’s also known as TIG welding, and Heliarc is a historical trade name for the same process. The term Heliarc appears in older equipment catalogs and welding literature as another name for GTAW. The other options describe different processes or are too generic: Arc Gas Welding isn’t a standard name for GTAW, Plasma Arc Welding uses a plasma jet, and MIG Welding uses a consumable filler wire.
