The electric arc discharge between the wire and the base metal generates heat, which melts the metal.GMAW welding is very similar to semi-automatic welding (MIG) because both use a continuous wire electrode and shielding gas. This allows for faster, higher quality welding of steel materials. what is the difference between GMAW and MIG? where is GMAW welding used? GMAW welding is used to join a variety of metal materials, including steel, aluminum, copper, nickel, and titanium. GMAW welding is a versatile, economical, and fast GMAW welding is a versatile, economical, and fast welding process that can be performed manually, mechanized, or automated. An electrical arc discharge between the wire and base metal generates heat, which melts the metal. The molten metal mixes with the molten electrode to form a weld pool. The weld pool solidifies to form the weld seam What is GMAW welding process adjustment? The wire feed rate is the speed at which the wire electrode is fed into the weld seam.
