An investigation on capability of hybrid Nd:YAG laser-TIG welding technology for AA2198 Al-Li alloy
TLDR
In this paper, the capability of the hybrid laser-arc welding in comparison with lone laser welding for AA2198 aluminum alloy was compared experimentally. But the results indicated that conduction mode occurred and keyhole was not formed even in low welding speeds and thus the penetration depth was so low.About:
