GTAW stands for?

• A. Gas Titanium Arc Welding
• B. Gas Tungsten Arc Welding
• C. Gas Metal Arc Welding
• D. Gas Thermal Arc Welding

Answer: (B)

GTAW stands for Gas Tungsten Arc Welding. This process uses a non-consumable tungsten electrode to create the arc, with the weld area shielded by an inert gas such as argon or helium. Because the tungsten electrode isn’t consumed, filler metal is typically added separately as needed, and the method is also commonly known as TIG welding (Tungsten Inert Gas). The other options don’t fit because the electrode in this process is tungsten, not titanium; a gas titanium arc designation would misidentify the electrode. Gas Metal Arc Welding refers to a different process that uses a consumable metal wire electrode (MIG welding), and Gas Thermal Arc Welding isn’t a standard name for GTAW.
