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.

The vibration is preferably applied in a direction crossing the feeding direction of the welding wire. A vibration under these conditions is preferably applied to a tip of the welding wire by using the forced vibration or resonance of the welding torch or the resonance of the welding wire itself.

摘要： In a pulsed arc welding method of the invention, a shield gas made mainly of carbon dioxide gas is used, and a low frequency pulse of 30 to 100 Hz is continuously generated, on which a high frequency pulse with a pulse frequency of 500 to 2000 Hz is superimposed. In this case, the welding current is determined such that an average peak current IPavg is at 300 to 700 A, an average base time Tb is at 5 to 30 ms, a current amplitude IP-a at a peak time of a high frequency pulse is at 50 to 600 A, and a current amplitude IPb at a base time of a high frequency pulse is at 20 to 200 A. This method ensures a reduced degree of biasing of a drop and an arc, for which the size, release time and release direction of a drop are kept substantially completely constant, and can achieve drop transfer wherein regularity of one pulse group-one drop transfer is very high. Hence, spatter and fume generation rates can be remarkably reduced.
