Document Type and Number:
WIPO Patent Application WO/2013/094182
Kind Code:
A1
Abstract:
The present invention relates to the press-forming of blank materials in which two or more kinds of blank materials have been combined and which limits cost increases and reduced producibility without causing forming defects. Multiple blank materials are disposed with partial overlaps and are pressed in the unwelded state. Of the overlap margin, at least the deforming region in which a change in form is generated with the press-forming is preferably kept unwelded. Welding of the overlap margin where the blank materials have been overlapped is preferably performed after the pressing.
