Abstract

There are some deficiencies such as inconsistency, oversize waist, and sharp corner in the cross-section of the welding seam. Orthogonal test is conducted under different speed, defocus, and offset. The metallic phase of the seam is observed by using electronic microscope. By analyzing the results of Erichsen test and tensile test, the effect of processing parameters on the performance of the seam is studied. The results show that deep punching performance will be improved and the waist will be reduced when the welding speed is increased. If the defocus is a quarter of the thick blank thickness and the offset value is 0.1mm, the surface of the welding seam will be smooth.
