Abstract

PURPOSE: To perform stable welding of high accuracy by giving torsional deformations of prescribed pitches to a curved welding wire.
CONSTITUTION: A welding wire 10a let off from a wire reel 11 is curved and defomed to a wire 10b by a curving and deforming device 15. Further, the wire 10b is pulled by a wire feeder 17, and is twisted by a twisting device 16 to a spirally twisted wire 10c. The welding wires 10b, 10c are regulated and fed to the state approximate to a straight line by the pulling force by the feeder 17, or the dimensional restrictions at the time of passing through a welding torch 12, etc., but at the part where they emerge from a power feed tip 13, the parts having received the elastic deformations are reset and are supplied to the weld zone in the state of spirally twisted deformation having a prescribed twist pitch and a twist radius (a). Hence, the leading end of the fed wire 10d rotates on the circumference of the radius (a) around a feed axis A, and the good weld beads of width wherein the side face parts of the groove of the work 14 are thoroughly melted are obtained.
