Experimental Study on Micro-Friction Stir Welding of Dissimilar Butt Joints Between Al 1050 and Pure Copper

The present study investigates the feasibility of producing strong and defect-free joints between 1050 aluminum and pure copper sheets by micro-friction stir welding using traditional and new tools. Many variables affect the quality of these types of joints that the parameters of rotational speed, welding speed, and tool offset are considered the main variables. The Taguchi method and analysis of variance were used to design the experiments and...
