Abstract

PURPOSE: To exclude stress concentration to the weld joint part to enlarge fatigue resistance strength, by performing welding again by the reverse soft plasma welding method after removing the oxide film near the boundary to the weld and part.
CONSTITUTION: Oxide film 16 on base metal 10 to be welded near weld end part 14 is ground previously by grinder grinding to form the removal face of oxide film 30 on the surface of base metal 10 to be welded. When plasma arc is irradiated near weld end part 14 processed in this manner by the reverse soft plasma welding method, the form of the plasma arc pole is extended to a fixed width, and heat energy of arc is dispersed to form a heat source optimum for the weld end part processing of the weld bead of a shallow weld penetration. The surface of weld bead 12 is convered with the oxide film because of no grinder grinding but is thin, and it has no influence upon the arc form for weld part processing and need not be removed.
