GMAW is commonly known by which of the following names?

• A. Gas Tungsten Arc Welding
• B. Gas Shielded Arc Welding
• C. Submerged Arc Welding
• D. Flux-Cored Arc Welding

Answer: (B)

GMAW, which stands for Gas Metal Arc Welding, is often referred to as Gas Shielded Arc Welding. This terminology emphasizes the process's reliance on a shielding gas that protects the weld pool from contamination during welding. In GMAW, a continuous solid wire electrode is fed through a welding gun, and an inert gas—typically argon, helium, or a mixture of these—is utilized to shield the arc and molten metal from atmospheric gases. The gas serves to ensure a cleaner, high-quality weld, making this name particularly appropriate. This understanding highlights why "Gas Shielded Arc Welding" is a widely accepted term for GMAW. The focus on gas shielding is essential in differentiating GMAW from other welding processes that may not employ shielding gases in the same manner.
