Abstract
Disclosed is a solid wire for arc welding, including: a flat portion of a wire surface with no copper plating, wherein micro Vickers hardness (Hv) of the flat portion is in the range of 115 to 310 and arithmetical average roughness (Ra) of the flat portion is in the range of 0.01 to 0.30·m. The solid wire is based on a new concept different from a conventional solid wire. The solid wire for arc welding has excellent feedability without copper plating, thereby improving weld workability. Consumption of energy during manufacture of the solid wire can be reduced because the solid wire is manufactured without copper plating, and a weld work environment can be improved because copper fumes are not generated.
