Aluminium - Copper alloy AA2219 finds application in aerospace and automotive components because of its high strength to weight ratio and corrosion resistance. However, joining of the alloy by conventional welding techniques results in poor property profile. In this study, AA2219 rolled plates of thickness 5.5 mm are joined by cold metal transfer welding process and friction stir welding process. The microstructure, mechanical, corrosion and wear properties of the welded plates are analyzed. The results indicate that cold metal transfer welded specimens have high hardness and tensile strength than the friction stir welded specimens. However, the corrosion resistance and wear resistance of friction stir welded specimens are higher than the base material and cold metal transfer welded specimens. © 2018 Jordan Journal of Mechanical and Industrial Engineering.
