Summary:Toyota has applied laser-welded tailored blanks for stamping side panel, door inner, front side member and many other auto body panels. Judgment on the formability in actual panel stamping is difficult, because the behavior in press forming of the portion near the weld lines differs from the base material. We have obtained by experiments the forming limits of the welded area for each of the basic forming patterns: stretch forming, flanging and deep drawing. The results have been used effectively in judging formability of actual parts stamping.
