Which welding process is commonly referred to as MIG welding?

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

Answer: (C)

Gas Metal Arc Welding, or GMAW, is the process commonly known as MIG welding. It uses a continuous wire electrode fed through the welding gun and relies on shielding gas to protect the arc and the molten metal from the air. That combination of a continuously fed filler wire plus shielding gas gives this method its widely used nickname, MIG welding. The other processes differ in how the electrode is used and how the arc is shielded: one uses a coated stick electrode with no separate shielding gas, another uses a tungsten electrode with shielding gas, and the last relies on a flux-core wire for shielding instead of a separate gas.
