Multiple Choice

GMAW produces a heavy slag coating that is easily removed.

Explanation:
GMAW relies on shielding gas to protect the weld pool and, when using solid wire, has no flux on the wire surface to form a slag layer. Slag is a byproduct created when flux melts and rises to the surface, which is common in processes like SMAW and many FCAW setups, not in standard GMAW. Because there is typically no slag coating to remove, the claim that GMAW produces a heavy slag coating is not accurate. In short, GMAW generally yields little to no slag, so the statement is false.
