Which welding process commonly uses a consumable electrode?

Which welding process commonly uses a consumable electrode?

• A. SMAW
• B. GTAW
• C. GMAW
• D. SAW

Answer: (A)

The main idea is that a consumable electrode is one that melts away during welding and becomes part of the weld. This option is the best answer because Shielded Metal Arc Welding uses a flux-coated, consumable electrode (the welding rod) that melts and deposits filler metal as you weld, while the flux provides shielding. That classic setup is what people first think of when asked about a consumable electrode. The other processes use different electrode types: TIG uses a non-consumable tungsten electrode (with filler metal added separately), MIG uses a continuous wire that is consumed but is a different commonly tested example, and submerged arc also uses a consumable wire but SMAW is the most typically associated in introductory questions.
