Gas Metal Arc Welding

• Gas Metal Arc Welding (GMAW=Gas Metal Arc Welding), also commonly known as CO2 welding, is an arc welding process that generates metal coalescence by heating the metal with an arc between a continuously fed filler metal electrode and a workpiece. The process uses a shield of externally supplied gas to protect the molten weld pool.
