Question: 1 / 400

What does GMAW stand for?

Gas Metal Arc Welding

Gas Metal Arc Welding (GMAW) is a type of welding process that uses a continuous solid wire electrode which is heated and melted by an arc between a continuous filler metal electrode and the workpiece. This process is shielded by an externally supplied gas (typically a combination of argon and carbon dioxide) to protect the weld pool from atmospheric contaminants.

Option A, Gas Metal Arc Welding, is the correct answer as it accurately represents the welding process known as GMAW. Options B, C, and D are incorrect because they do not accurately reflect the correct term for the acronym GMAW.
