Abstract


Friction Stir Welding (FSW) represents a cutting-edge and innovative welding method. It utilizes a non-consumable tool, avoids melting the material, operates in all positions, provides excellent mechanical properties, and has a minimal impact on the environment. This paper provides an analysis of the experimental results of friction stir welding beads for three different aluminum types alloys: AA7075, AA6061, and AA2024 welded together, overlapped. During the experiments, the position of the aluminum alloy plates and the advancing speed were kept constant, while the rotation speed was varied. The exit data recorded during the process and measured afterward on FSW beads will be analyzed and compared to determine the impact of rotation speed on the joint properties.
