Abstract

In this work, we investigated the technological features of promising technologies for laser welding and friction stir welding of high-strength aluminum-lithium alloy V-1469. The modes of laser welding and friction stir welding have been carried out. In this article, we showed the perspective welding methods provide high values of ductility and impact toughness, while the strength of welded joints is not less than 0,8 of the strength of the base material and values of low cycle fatigue is not less than 110·103 cycles. The results allows to propose laser welding and friction stir welding processes as an alternative to riveted joint for aluminum-lithium alloy V-1469 as applied to the elements of the fuselage.
