Effects of welding parameters on the penetration of austenitic stainless steel A-TIG weld seam with the home-made active flux were carried out.

利用自制的活性剂，考察了焊接工艺参数对奥氏体不锈钢A-TIG焊焊缝熔深的影响。

However, it is not obvious in penetration increase for PAW through using of flux compared with TIG welding, but significant improvement in weld shape has been found in PAW.

对于PAW焊，熔深也有增加，但是增加的幅度不如TIG效果明显，但对焊缝成形有很好的改善。

Some experiments, including weld deviation experiment, A-TIG welding experiment with DCSP mode and FBTIG welding experiment, are made to study the mechanism of activating flux improving penetration.

通过焊接偏移试验、直流正接A-TIG 焊试验和FBTIG 焊试验研究了活性剂增加熔深的机理。
