Wires for the gas shielded arc welding are usually plated with copper to guarantee the good corrosion resisting property and low electric resisting property. But there is a problem if this plated copper may have some effects on the welding and the properties of weld metal. The investigation was made to examine the influence of the copper plating on the corrosion of wire, the deposition loss of copper to weld metal and the influence of the copper content on the mechanical properties of weld metal by CO_2-O_2 arc welding. The results obtained were as follows : 1) Copper plating of more than 0.5μ gives the considerable corrosion resisting even in wet atmosphere. 2) There is no deposit loss of copper to weld metal by CO_2-O_2 arc welding. 3) If copper plating of wire is controlled within from 0.5μ to 1.2μ thick, the mechanical properties of weld metal will not be affected by the copper of wire.
