摘要：
Laser-MIG hybrid welding was carried out on 304 stainless steel in order to study the hybrid effect of two heat sources of laser and MIG. The influence of energy parameters including laser and MIG power and their line energy of hybrid welding on weld formation was investigated and the optimal energy ratio between laser and MIG arc was got in this study. The results show that the increase of laser power has a dominant effect on the increase of weld penetration, while the increase of MIG arc power has a small effect on the increase of weld penetration which is mainly used to improve forming stability and welding bridging ability. Hybrid effect of laser power and arc power on formation was investigated and processing window diagram was obtained which is of great guiding significance.
