摘要

综述TIG-MIG复合焊接方法的研究现状,介绍TIG-MIG复合旁路、TIG-MIG间接电弧、TIG-MIG双面双弧焊接的工艺特点,讨论目前TIG-MIG复合焊研究中遇到的问题和未来发展的潜在领域。TIG-MIG复合焊接是一种新型复合焊接方法,兼备了TIG焊高质量及MIG焊高效率的综合优势,其电弧耦合行为、熔滴过渡过程及热源特征为今后的研究热点,同时TIG-MIG复合焊接工艺可拓宽至异种金属焊接、窄间隙焊接等特殊领域。

Abstract

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.
