Abstract
PURPOSE: To automatically and accurately weld the weld line which is changing intricately by forming a narrow square groove in a base pipe, and performing flat welding while turning a welding head along the outside circumference of a small- diameter part at the orthogonal connecting of a thick-walled large-diameter pipe and a thick-walled small-diameter pipe.
CONSTITUTION: The nozzle 2 of a thick-walled small-diamter pipe connecting to a thick-walled large-diameter base pipe 1 is disposed in the direction orthogonal to the base pipe 1. A narrow square groove 4 is formed at the circumferential edge of the connecting port of the base pipe 1. A welding head 9 is turned to the outside circumferential side of the nozzle 2 around the slewing shaft 10 disposed in alignment to the axial center of the nozzle 2, and while the head 9 is being traced vertically by a sliding arm 13, the narrow square groove is successively multilayer welded by a welding wire 5. This method enables the saddle type weld line changing intricately to be welded accurately by automatic multipass welding only through the tracing controlling in the vertical direction.
