It is a gas arc welding wire used for welding cast steels, pipe steels and general structural steels. It is sold 1.2 mm. It is used as a shielding gas according to the thickness of the base metal. It is used in industries such as automotive, steel structure, shipbuilding and machinery. It is generally recommended to preheat according to the thickness and carbon equivalent of the material to be welded. Gas metal arc welding wires with thin copper coating increase the electrical conductivity and the resistance of the wire against corrosion.
