深熔TIG焊研究现状与展望

Research Status and Prospect of Deep Penetration TIG Welding

TIG焊具有焊接过程稳定、焊缝质量优良、焊接无飞溅、适于全位置焊接等诸多优点,但同时也存在熔深浅、焊接速度慢、熔覆速率低等缺点。为了克服TIG焊熔深浅的缺点,提出了多种增大熔深的新型深熔TIG焊接方法。总结了活性TIG焊、K-TIG焊、DP-TIG焊、磁控深熔TIG焊等几种深熔TIG焊接方法的最新研究进展,归纳了深熔TIG焊接方法存在的问题,并展望了未来深熔TIG焊接方法的几个研究方向。

TIG welding has many advantages such as stable welding process, good weld quality, no spatter and suitable for all-position welding, but it also has disadvantages such as small welding penetration, slow welding speed and low cladding rate. In order to overcome the shortcomings of small TIG welding penetration, a variety of new deep penetration TIG welding methods were proposed to increase the welding penetration. The latest research progress of active TIG welding, K-TIG welding, DP-TIG welding and magnetic controlled deep penetration TIG welding were summarized, the existing problems of deep penetration TIG welding were summarized, and the future research directions of deep penetration TIG welding were prospected.
