How does arc length vary with gmaw processes
WebJun 22, 2024 · At present, gas metal arc welding (GMAW) is the most widely used welding process in the manufacturing and construction industries [].With this process, the stability of the arc needs to be controlled to obtain a weld of the desired quality, as the transfer of molten metal from the electrode to the weld pool determines the integrity of the weld [1,2,3]. WebNov 22, 2010 · As more advanced power sources became available, operators began using constant voltage (CV), a GMAW process that closely regulates arc length. Made since the 1990s, CV power sources demonstrated more stable output than CC power sources on various materials, including aluminum, by keeping arc length constant during changes in …
