Abstract
Investigations were carried out into the special features of the formation of the structure and properties of laser welded joints in V-1461 and V-1469 aluminium–lithium alloys. The results show that the application of the filler materials of the Al–Cu systems alloyed with rare-earth metals improves the formation of the welded joint and decreases the probability of formation of defects. Complete heat treatment of the welded joints increases their strength characteristics to 0.9 of the strength of the parent material.
