The Gas Metal Arc Welding process is where an arc is struck between the base metal and a continuously supplied consumable wire. Which provides filler metal for the weld and this process is one of the oldest ways to perform welding; it is basically performed on the non-ferrous metal. The Gas metal arc welding can open up the possibilities to weld all metal for which the consumables are available, initially, the process was mainly performed on aluminum and stainless steel with inert gas shielding.
The electrode is bare, containing no coating or core. The shielding, to protect the molten metal from reacting with constituents of the atmosphere, is supplied by an external gas, usually containing one or a mixture of the following: helium, argon, or carbon dioxide. A major amount of fume can be generated when welding with this process. Most of the fume generated during the Gas Metal Arc Welding process is derived from the consumption of the electrode and not from the base metal.
