Gas metal arc welding is currently the most widely used arc welding process, having overcome the old faithful “stick†welding, SMAW. It was developed to make welding a faster, more profitable process. Benefits such as high production rates, high weld quality, ease of automation, and the ability to weld many metals make it attractive to manufacturers. All commercially important metals, such as carbon steel, high-strength low-alloy steel, stainless steel, aluminium, copper, and nickel alloys can be welded in all positions. A typical application is welding of aluminium bus bars in electrical industry and welding of sheet metal assembly. Gas metal arc welding process has become more popular in weld cladding than other processes due to its numerous advantages.
