Abstract: This study focuses on the bonding interface characteristics and mechanical properties of the bobbin tool friction stir welded dissimilar AA6056 and AA2219 aluminum alloy joints using different welding speeds. Voids arise solely in the stir zone at the AA2219 side. A distinct boundary with limited material mixing develops at the middle section of the bonding interface, while excellent material mixing with an irregularly jagged pattern forms at the top and bottom sections of the bonding interface. Increasing the…
