GMAW stands for?

GMAW stands for?

• A. Gas Magnesium Arc Welding
• B. Gas Metal Arc Welding
• C. Geometric Metal Arc Welding
• D. Gas Metal Alloy Welding

Answer: (B)

The main idea here is recognizing the standard name of this welding process from its acronym. Gas Metal Arc Welding is the correct expansion of GMAW. In this process, a continuous metal wire electrode is fed through the welding gun, the electric arc between the electrode and the workpiece melts the metal, and shielding gas protects the molten pool from the atmosphere. The word order in the acronym maps to the key elements: Gas refers to the shielding gas, Metal to the electrode, Arc to the welding arc, and Welding to the process itself. The other options don’t fit because they introduce terms that aren’t part of the official name: magnesium suggests a different element, geometric isn’t a welding term, and alloy would imply a different naming convention than the standard Gas Metal Arc Welding.
