In this paper,the research status of TIG-MIG hybrid welding is reviewed. The process characteristics of TIG-MIG composite bypass welding,TIG-MIG indirect arc welding and TIG-MIG double-sided double arc welding are introduced. The recent problems and potential applications of TIG-MIG hybrid welding are discussed in finally. TIG-MIG hybrid welding is novel hybrid welding method. It has the comprehensive advantages of high quality TIG welding and high efficiency of MIG welding. Arc coupling behavior,droplet transfer process and heat source characteristics in TIG-MIG hybrid welding are the hot topics in the future,and the TIG-MIG hybrid welding process can also be extended to special fields such as dissimilar metal welding and narrow gap welding.
