[0010] Example 1
[0011] The present invention provides a welding seam forming process of a vehicle door connection structure, which is characterized in that: the welding seam forming process of the vehicle door connection structure is controlled by the program: 2mm The length is the arc starting section, and the focusing current is controlled to be, and the welding current is from 0 Rise to 10 , The trajectory of the welding section is from the rightmost near-distance point to the leftmost near-distance point; continue from the leftmost near-distance point at the right end of the zoom section to the midpoint of the transition section between the near-distance section and the far-distance section of the zoom section. Change, the focus current drops; the high voltage is 60KV , The welding speed is 60mm / s 。
