大熔覆速率TIG焊研究现状与展望

Research Status and Prospect of High Cladding Rate TIG Welding

摘要: TIG焊具有焊接电弧稳定，焊缝成形美观，焊接过程无飞溅等优点，但也存在熔覆速率低的缺点。本文总结了热丝TIG焊、TOP-TIG焊、TIP-TIG焊、双钨极TIG焊、窄间隙TIG焊等几种提高TIG焊熔覆速率的高效TIG焊接方法，归纳了这几种大熔覆速率TIG焊接方法存在的问题，并展望了未来的发展方向。

Abstract: 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.
