氦弧焊

对接间隙对钽薄板TIG氦弧焊熔池形态影响的数值分析

Numerical Analysis of Effect of Butt Gap on Molten Pool Form in TIG Helium-arc Welding of Tantalum Sheet

对焊渣进行了SEM形貌观察和EDS成分分析，并采用氦弧焊证实了焊接过程中焊渣在熔池表面成片分布，电弧斑点极大收缩。

Then SEM observation and EDS analysis of slag are carried out respectively . Separate distribution of slag on welding pool during welding and great constriction of arc spots are confirmed by TIG welding with helium shielding gas .
