WebJan 1, 2024 · In the early 1900s GMAW process was introduced and in 1948, the process was commercially accessible. GMAW was considered as elevated current density, miniature diameter, and uncovered metal electrode process with an inert gas for arc shielding. WebFeb 12, 2015 · Spray – The spray transfer mode is the original transfer method for GMAW and was developed in the 1940s to allow for the welding of non-ferrous metals such as aluminum. In this transfer mode the welding electrode is rapidly passed along a stable electric arc to the workspace, resulting in a better weld finish with very little or no spatter.
