GMAW and GTAW began being used to weld heavy sheet metal in which decade?

Explanation:
GMAW and GTAW were developed and started seeing practical use in the 1940s. The wartime demand for faster, higher‑quality welding of aircraft, ships, and other heavy sheet metal spurred invention and early adoption of these processes. MIG offered faster deposition and better productivity, while TIG provided precise, high‑quality welds on metals like aluminum. As shielding gas technology and equipment improved, these methods began to be used for heavy sheet metal in the late 1940s, paving the way for wider adoption in the following years.
