Abstract

The structure and phase composition of the lap joint of aluminum alloy AMg6 obtained by friction stir welding are studied. The formation of complex macroscopic defects in the welded joint is detected. The conditions for the formation of macroscopic defects in aluminum joints obtained by friction stir welding and methods for preventing the formation of defects are discussed.
