Abstract：

Forming limit diagram is a simple and direct method for estimating metal blank properties. It is an efficient tool for blank stamping. The forming limit of spot welding tailored blank was studied by an experiment and simulation method. The result indicates that when the spot welding tailored blank is in the biaxial tension state, the peak value distributions of various field variables of spot welding tailored blank show obvious directionality. The rupture zone of the low plate is near the spot weld along the axle wire in width, while the rupture zone of the up plate lies near the spot weld along the axle wire in length. The more closed bidirectional tension is, the more closed the peak value of biaxial variables and also the probability of rupture are.
