プレス型に損傷を与えるという問題があった。However, in the above-described conventional method for manufacturing a press-formed product, when the plate thicknesses of adjacent panel materials joined by butt welding are different,
Alternatively, when the joining sides are overlapped and weld-joined, the plate thickness changes abruptly at the joint portion, and the clearance of the working surface of the press die can take only the plate thickness. At this time, it is necessary to position the range where the plate thickness changes abruptly in the mold escape, which is a recess formed by recessing from the machined surface of the press mold, but if the work position shifts in the press mold, the product cannot be produced. Not only that, the thick joint moves to the position where the clearance is small,
There was a problem of damaging the press die.
