Research Status of Advanced Laser-MIG Hybrid Welding Technology

Laser-MIG hybrid welding can effectively improve the single laser welding and traditional MIG welding process, reduce welding defects in some extent, improve welding efficiency and increase welding penetration, the comprehensive mechanical properties of the welds are effectively improved. At present, it has been applied in aerospace, shipbuilding and other industrial fields.The research status of advanced laser-MIG hybrid welding technologies in China and foreign countries, for example, narrow gap laser-MIG hybrid welding, oscillating laser-MIG hybrid welding, laser-MIG double-wire hybrid welding and energy field auxiliary laser-MIG hybrid welding, etc. was summarized. It can provide references for Chinese and foreign scholars to study high-quality and high-efficiency laser-MIG hybrid welding technology.
