Abstract:
Laser-assisted welding of the 1420 alloy of the Al–Mg–Li system is experimentally studied for the purpose of its optimization. Various regimes of thermal treatment of non-detachable joints obtained by means of laser welding are considered. Thermal treatment modes that allow significant enhancement of the welded joint density as compared to the as-received alloy are chosen. The ultimate normalized elongation of samples after aging is found to decrease by a factor of 3.
Keywords:
