Abstract

PURPOSE:To enable square welding with good quality without causing any defect by providing guide grooves in which the top end of a welding nozzle is moved along a weld line to the holder of the welding nozzle, providing guide members that engage with said grooves and moving the nozzle. CONSTITUTION:Grooves 42, 44-52 which guide the top end of a nozzle 30 are provided to plates 22, 24 which grasp the nozzle 30 and a wire feeder, thereby constituting a holder. The shafts 54, 56... of a nozzle support 31 are engaged with the grooves 42, 44... and guide members 60, 62... are provided to the respective top ends thereof. A nozzle moving mechanism which moves said guide members along a guide 78 and is driven by meshing of a motor 70 and gears is provided. Welding is started from a point 102 with the nozzle 30 set in the state of starting welding (leftmost in the figure) and the nozzle is moved along the grooves 42, 44... in the direction of an arrow to turn the top end of the nozzle as shown by an arrow L. Square welding is thus made possible with the same quality without any defect.
