FIELD: process engineering.
SUBSTANCE: invention relates to blanks intended for cold forming of structural parts, in particular, car body components. Proposed blank consists of parts welded of steel sheet, band or strip selected proceeding from strength and formability. Components of the part are composed of figures welded in straight lines. Welded seams are arranged in the lines of projection along welded seams of said components on blank side with shorter seams. Blanks feature sizes with machining allowances at the edges to be welded.
EFFECT: decreased wastes, lower labour input, higher strength.
