Beschreibung
Zusammenfassung:	[Object] In a press-formed product obtained by press forming a tailored blank, the width of the weld bead is brought closer to the target width.[Solution] A method of designing the width of the weld bead in a tailored blank includes: a model acquisition step S11 for acquiring analysis model data containing elements for the first sheet, elements for the second sheet, and elements for the weld bead; a press-forming analysis step S12 for performing press-forming analysis using the analysis model data to calculate deformation of the various elements when the tailored blank is press formed; and a bead-width designing step S14 for deciding on a design value of the width of the weld bead for each of positions along the longitudinal direction of the weld bead in the tailored blank prior to press forming based on a press-forming-induced change in the width relating to the elements for the weld bead obtained through calculation, to generate bead-width design data indicating the relationship between a position along the longitudinal direction of the weld bead and the design value of the width of the weld bead.
