Research Status and Prospect of High Cladding Rate TIG Welding
TIG welding has the advantages of stable welding arc,beautiful weld forming and no spatter in welding process,but it also has the disadvantages of low cladding rate.Several efficient TIG welding methods to improve the cladding rate of TIG welding were summarized,such as hot wire TIG welding,TOP-TIG welding,TIP-TIG welding,double-tungsten electrode TIG welding and narrow gap TIG welding.The existing problems of the high cladding rate TIG welding methods were summarized,and the development direction in the future was forecasted.
