Abstract:
A method for manufacturing a sheet metal blank, in particular a tailored blank, in which at least two metal sheets are connected to one another at their respective connecting edges, the two metal sheets displaying differing thickness is provided herein and allows in a simple manner an application-specific configuration of the region of transition from one metal sheet thickness to another metal sheet thickness. The method includes a step in which, prior to the connecting of the two metal sheets, at least the region of the connecting edge of the thicker of the two metal sheets is pressed to a predefinable thickness in a forming tool in such a way that the connecting edges of the metal sheets display substantially the same thickness.
