The microstructure and mechanical properties of joint welds formed by linear friction welding (LFW) in in Al-Cu-Mg alloy was investigated. Joint welds of two samples of rectangular shape do not possess any macroscopic defects and are characterized by high strength. The substantial transformation of the microstructure occurs in the weld zone as a result of plastic deformation and deformation heating during LFW
