Which process is MIG welding?

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

Answer: (A)

MIG welding is Gas Metal Arc Welding. In this method, a continuous solid-wire electrode is fed through a welding gun and shielding gas protects the arc and molten weld pool. That combination—continuous wire plus shielding gas—is what defines the MIG approach, which is why the best answer is the option describing GMAW (Gas Metal Arc Welding). SMAW uses a coated stick electrode, not a continuous wire with shielding gas. GTAW uses a tungsten electrode with separate filler metal and shielding gas. FCAW uses a flux-filled core wire that provides its own shielding, rather than relying on a separate shielding gas in the same way as MIG.
