针对钛金属的性质,做了氧、氮、氢和空气对钛金属焊区的影响的试验,以及惰性气体保护焊接的工艺试验。试验结果表明了采用惰性气体保护焊接的必要性。

A series of tests have been made to examine the effects of O2, N2, H2 and air on laser welding of titanium and inert gas was used to protect the welding section. Our experimental results indicate the necessity of using inert gas as a protective measure in obtaining satisfactory welding effects.
