Abstract
An arc welding solid wire includes: a steel material; and a copper plating layer formed on a surface of the steel material, in which an amount of Cu in the steel material and the copper plating layer is 0.05 mass % to 0.30 mass % with respect to a total mass of the wire, a surface of the wire is coated with 0.05 g to 0.20 g of oil with respect to 1 kg of the wire, and on a surface of the copper plating layer, an arithmetic average roughness Rac in a circumferential direction is 0.25 μm to 1.00 μm, and an arithmetic average roughness Ral in a longitudinal direction is 0.07 μm to 0.50 μm.
