Abstract :In this study, Aluminium 5754-7075 plates in 2.0 mm thickness were joined by magnesium-based insert ignore into journalissuearticles values(AlMg5); wire in cold metal transfer insert ignore into journalissuearticles values(CMT); technique. The specimens were prepared in butt joint form. Argon was used as shielding gas and joining operations were done with 20o working angle. Joining operations were done with four different gas pressures as 10, 12 14, 16 l/min. After that, tensile properties of joints were determined and macro-structures of joints were investigated in order to see the joinability of aluminium 5754-7075 alloy by CMT insert ignore into journalissuearticles values(cold metal transfer); technique. Finally, the micro-hardness values of specimens were measured.
