GMAW-P welds made on most metals other than steel use __________shielding gas.

Question

Quizplus · Accepted Answer

When welding metals other than steel with GMAW-P, 100% argon is generally considered the best choice of shielding gas. This is because argon provides good arc stability and coverage while also minimizing the risk of oxidation, which is particularly important when welding reactive metals like aluminum. Options A, C, and D all involve a mix of argon with other gases, which may have their own benefits in certain situations, but are not typically favored as the primary shielding gas for non-steel GMAW-P welding.
