Nebraska GTAW FFA TIG Welding Practice Exam

Gas Tungsten Arc Welding describes a welding process that uses a non-consumable tungsten electrode to create an arc, with the weld zone protected by an inert shielding gas. Each word signals a fundamental part of the method: Gas refers to the shielding gas, Tungsten to the electrode material, Arc to the arc welding action, and Welding to the overall process. This combination precisely defines GTAW, which is also known as TIG welding. The other phrasings misrepresent either the electrode, the shielding gas, or the nature of the process (for example, naming only a gas or swapping in alloy/anode).
