The welding process commonly referred to as MIG welding is which?

• A. Flux Cored Arc Welding
• B. MIG Welding
• C. Shielded Metal Arc Welding
• D. Self-Shielding Process

Answer: (B)

MIG welding is a gas shielded arc welding method where a continuous solid wire electrode is fed through a gun and melted by the arc, with shielding gas protecting the weld from the atmosphere. That combination—continuous wire plus external shielding gas—is what people mean by MIG welding, and the term is shorthand for Metal Inert Gas or, more precisely, Gas Metal Arc Welding (GMAW). This distinguishes it from Flux Cored Arc Welding, which uses a hollow wire filled with flux and may be self-shielded or gas-shielded; FCAW-S refers specifically to the self-shielded variant. Shielded Metal Arc Welding uses a coated stick electrode and produces slag, not the MIG process. Therefore, the welding process commonly referred to as MIG welding is the MIG Welding.
