WELDING SYSTEM

摘要

In a welding system for performing butt welding which comprises butting the end surfaces of steel plates, materials to be welded, placed on the upper surface of a table of a welding stage and welding the end surfaces together,a welding head is a laser/arc combined welding head for simultaneously performing laser light irradiation and arc discharge of the materials 38 to be welded, thereby welding the materials to be welded, andthe position of an arc electrode 40 in an up-and-down direction relative to the materials 38 to be welded, the position of the arc electrode in a direction perpendicular to the direction of the optical axis of laser light 32 applied to the materials 38 to be welded, and the inclination angle of the arc electrode relative to the optical axis of the laser light 32 can be adjusted.
