摘要

Compared with traditional tungsten inert gas (TIG) welding, TIG-based hybrid arc welding is a more efficient welding process. In this paper, we review the current research on twin-TIG hybrid arc welding and TIG-MIG (metal inert-gas welding) hybrid arc welding and introduce the temperature field distribution and transfer, the interaction between arc static pressure and Lorentz force, and the plasma flow and metal solution flow in hybrid welding. We summarize the coupled behavior of the arc, the transition of the molten droplets, and the characteristics of the molten pool flow. We also list the weldability of materials in TIG-based hybrid arc welding and the influence of welding parameters on welding joint quality and efficiency. The results show that in twin-TIG-based hybrid welding, the coupling of the arcs causes a significant decrease in arc pressure on the surface of the molten pool, which is helpful in adopting a larger heat input to improve efficiency in hybrid welding. In TIG-MIG hybrid welding, the TIG arc stabilizes the MIG welding arc and reduces the occurrence of welding defects, thereby improving welding efficiency. Finally, we introduce the recent developments in TIG-based hybrid arc welding and provide prospects for its future development directions.
