Friction stir welding of V-1469 high strength aluminium–lithium alloy

Abstract

The results of investigations of the effect of the technology for repairing defects, formed in friction stir welding of V-1469 aluminium alloy (secondary pass, manual argon-shielded arc welding), and of the effect of heat treatment on the mechanical properties and nature of failure of the welded joints are presented.
