ABSTRACT:
Method and apparatus for high-power-density beam welding in combination with upset welding. The method comprises forming, along abutting edges of metal materials to be welded, a continuous upset weld line, and subsequently beam welding the metal materials by irradiation by a high-power-density beam along the weld line. The output of the high-power-density beam is determined on the basis of an input heat produced by resistance heating in the metal materials during the upset welding, as well as a welding pressure given to the metal materials during the upset welding.
