Microstructure and hardness of extrusion welding on hollow panel AA6061 aluminum alloy

Given the length of the structure, extruded products are occasionally joined to reach the desired length. To minimize production costs, this joint is achieved through extrusion welding, where it takes place while the workpiece is still a heated billet inside a chamber. As extrusion structures differ in complexity, this study seeks to identify the traits of extrusion welding outcomes across various structural designs. Research findings suggest that structural design significantly impacts both the physical and mechanical properties of the extruded plate and the extrusion joints.
