| Abstract: | Deep drawing of tailor welded blanks(TWBs)of the same material and different thickness, different material and the same thickness and different material and different thickness are studied by experiment. The movement law of the weld seam is acquired. The law is that the weld seam moves towards the thick part on the bottom of the square boxes and towards the thin part on the wall of the square boxes. The effect of blank holder force and yield stress on the movement distance of the weld seam is analyzed. The flange wrinkling and the excessively thinning are also analyzed. |
| Keywords: | tailor welded blanks deep drawing square boxes |
