    摘要： A plating-free solid wire for arc welding has pits opening on its circumference, and wider inside than at each opening, and/or pits having a portion non-irradiated with an externally incoming light. A sulfide and a polyisobutene-containing oil are present in the pits and/or on the wire surface, the latter being present in an amount of 0.1-2 g/10 kg of wire. Twenty or more pits are present in total per and along wire circumference. The effective pit length ratio is 0.5% inclusive-50% exclusive. 0.1-2 g of the oil is present per 10 kg of wire. 0.01-0.5 g/10 kg of 0.1-10-&mgr;m-particle-dia MoS2 is present in “bottleneck-like and/or cave-like pits”, on the wire surface or immediately under the wire surface. A 2-10 mass ppm/total wire mass of K compound in K is present in the pits and/or on the wire surface. These ensure good feedability and lubricating properties, and less spatters.
