Abstract

The effects of die structure such as the height of the welding, the welding angle and chamber the shape of the bridge on the welding quality of profiles were investigated by means of the commercial software DEFORM-3D. The numerical simulation results show that the welding quality of the hollow profiles has great sensitive to the die structure. With increasing the welding chamber height and decreasing the welding angle of the die leg can improve the welding quality. In addition, the welding quality index k of the new designed shape of the die leg is little down from 4.1 to 3.9 comparing the standard leg.
