GMAW stands for which welding process?

• A. Gas Metal Arc Welding
• B. Gas Manual Arc Welding
• C. Gas Metal Aluminum Welding
• D. Gas Molten Arc Welding

Answer: (A)

Gas Metal Arc Welding is the correct name for GMAW. This process uses a continuously fed metal electrode wire and a shielding gas to protect the weld pool from atmospheric contamination. The arc forms between the electrode and the workpiece, melting the wire as it creates the weld bead, allowing fast deposition and easy control. It’s commonly called MIG welding in many places, but the acronym GMAW stands for Gas Metal Arc Welding. Other phrasing isn’t standard for this process. Gas Manual Arc Welding isn’t a recognized term and would imply a manual arc without the continuous feed and shielding gas. Gas Metal Aluminum Welding suggests a metal choice rather than the process name, and Gas Molten Arc Welding isn’t a standard welding process.
