Abstract (en)
[origin: EP1186358A2] A blank is produced from a base sheet of a first steel material. A section of the base sheet is replaced by a sheet metal blank (1,2), which has different thickness and/or material characteristics from the first base sheet. Thickness, geometry of the blank, and its position in the blank are determined by the material flow during subsequent cold forming of the blank into a component, e.g. a tube (R).
