Abstract
PURPOSE: To eliminate the damages of jigs owing to oozing of spatter and improve welding strength by forming small protrusions in the specified positions of the 1st part in projection-welding the relatively small 2nd part to the 1st part.
CONSTITUTION: In projection-welding a relatively small part B (boss or the like) to a part A (impeller main plate or the like of pump), ring-form or a number of small protrusions 4 are formed in the position of the part A opposing to the outside circumference part 5 of the part B and the part 13 is positioned and centered by a centering jig 3 in the manner similar to that in conventional embodiments, whereby projection welding is accomplished. As a result of this, spatter 6C oozes to outward of the outside circumferential part 5 of the part B without oozing toward the jig 3, thus becoming the bead-form fusion-welded parts 6C. According to this method, the part B may be made smaller, there are no damages of the jig 3 owing to oozing of spatter and the strength after welding stabilizes.
