Abstract
Laser welding of the 1420 alloy of the Al–Mg–Li system is experimentally studied for the purpose of its optimization. Various modes of heat treatment of fixed joints obtained by means of laser welding are considered. Heat treatment modes that allow significant enhancement of the welded joint density as compared to the as-received alloy are chosen. The ultimate relative elongation of samples after ageing is found to decrease by a factor of 3.
