Abstract
The automotive intelligent dual-pulse MIG composite arc technology fully integrates both laser and arc welding advantages. This paper analyzes the pulsed MIG arc. At the same time, the experiment adopts the new "Hyper Dip-pulse" intelligent control technology on the all-digital welding power source of the automobile production line. The experiment achieved the welding effect of a stable molten pool, increased penetration depth, and reduced porosity defects in stainless steel alloy welding. The double-pulse MIG composite arc welding significantly affects the weld width but has a limited effect on the weld penetration. Under the optimized process parameters, the double-pulse MIG hybrid welding can effectively eliminate the surface forming defects in the stainless-steel alloy laser weld, and the welding speed is increased by 50%.
