Is the following statement true or false? GTAW uses a consumable electrode.

Is the following statement true or false? GTAW uses a consumable electrode.

• A. True
• B. False
• C. Only for stainless steel
• D. Depends on the welding application

Answer: (B)

The statement is false because Gas Tungsten Arc Welding (GTAW), also known as TIG (Tungsten Inert Gas) welding, utilizes a non-consumable tungsten electrode. This means that the tungsten electrode maintains its form and is not consumed during the welding process. Instead, filler material can be added separately if needed, but the primary electrical arc and heat source come from the non-consumable tungsten electrode. In contrast, other welding processes, such as MIG (Metal Inert Gas) welding, do use consumable electrodes. Understanding this distinction is crucial for recognizing the specific characteristics and applications of different welding methods.
