WIPO Patent Application WO/2022/230836

A1

[Problem] To bring the width of a weld bead of a press-formed article obtained by press-forming a tailored blank material close to the intended width. [Solution] A weld bead width design method for a tailored blank material, said method having: a model acquisition step S11 for acquiring analysis model data that includes a first plate material element, a second plate material element, and a weld bead element; a press-forming analysis step S12 for calculating, by means of a press-forming analysis using the analysis model data, the deformation of each element when a tailored blank material is press-formed; and a bead width design step 14 for determining a design value for the width of the weld bead at each position in the lengthwise direction of the weld bead of the tailored blank material prior to press-forming on the basis of a change in the width of the weld bead element caused by the press-forming and obtained by the calculation, and generating bead with design data indicating a relationship between the position of the weld bead in the lengthwise direction and the design value of the width of the weld bead.
