Abstract

PURPOSE:To prevent the generation of an undercut at a weld zone by forcibly press the both metal materials mutually in the width direction prior to the molten metal of a weld zone being solidified in the case of welding the end faces of a dissimilar metal and alloy strip, bar-like material by their abutting. CONSTITUTION:In the case of welding the stainless steel sheet 5 of SUS 304, etc., and an invar alloy sheet 4 by the end face in its length direction, a springed 2 guide roll 1 is provided on the position immediately after the weld zone 7 of the both metal sheets and the end face of the weld zone of both metal sheets 4, 5 is pressed each other. In this case the press amt. of both metal sheets 4, 5 is made smaller by about 0.2mm than the total dimension of both materials 4, 5 by providing a stopper 3 on said guide roll 1. The molten metal by welding is solidified by being pressed by both materials 4, 5 prior to its solidification, so the generation of an undercut on a welding bead 6 is prevented.

According to the present invention, the occurrence of undercuts is minimal or completely eliminated. In addition, in order to remove the bulge on the bead that occurs as a result of this, it is sufficient to perform rolling or polishing to the extent of a skin pass after juxtaposition, which can reach 20 to 30% more than the conventional undercut I countermeasure. The number of man-hours can be significantly reduced compared to rolling and polishing. In addition, in the present invention, "forcibly pressing" refers to the above-mentioned Japanese Patent Laid-Open No. 57-5
This does not mean pushing to the extent that no gaps are created, as shown in No. 6198, but pushing it so that the width of the plates after they are joined in parallel is smaller than the total width of each material before they are joined in parallel.
