TIG welding primarily uses which material as its electrode?

Aluminum
Steel
Tungsten
Wire

The correct answer is: Aluminum

Tungsten is primarily used as the electrode material in TIG (Tungsten Inert Gas) welding. Tungsten has a high melting point, which allows it to maintain its structural integrity at the high temperatures generated during the welding process. This property makes it an ideal choice for use as the electrode in TIG welding. Aluminum, steel, and wire are not typically used as electrode materials in TIG welding.
