摘要： PURPOSE:To increase the feed quantity of a welding wire, to increase the deposition quantity, and to improve its deposition efficiency by constituting a welding device of plural wire reels for feeding a welding wire, a device for twisting a fed welding wire, and a feed reel for feeding a twisted welding wire to a torch. CONSTITUTION:Thin welding wires 3,3... fed out of wire reels 2,2... are twisted by a twisting device 4, become a twisted welding wire 6, it is fed to a torch 9 by a feed reel 7, and welding is executed. Accordingly, a current density applied to one piece each of the thin welding wires 3 for constituting the twisted welding wire 6 becomes higher than a solid welding wire, the same wire diameter D can be melted by a small current, and as for the solid welding wire and the twisted welding wire 6 having the same sectional area, the feed quantity of the twisted welding wire 6 can be made more than the former, therefore, the deposition quantity is increased.
