Using the Friction Stir Welding (FSW) method and incorporating a new fixture, copper and aluminum tubes were welded in a lap joint configuration, producing bimetallic copper-aluminum tubes with appropriate interdiffusion. Moreover, the effects of welding parameters such as the rotational and traverse speeds on the macro- and microstructure, the hardness profile, and the shear strength of the samples were investigated. The results showed a stronger joint is achieved by increasing the traverse speed from 30 to 60 mm/min and reducing the rotational speed from 1000 to 710 rpm. Furthermore, it was found that the curvature of the tubes and the difference in their physical properties are quite challenging when welding copper and aluminum tubes using this method.

使用摩擦搅拌焊接（FSW）方法并结合新的夹具，铜管和铝管以搭接方式进行焊接，从而生产出具有适当相互扩散作用的双金​​属铜铝管。此外，还研究了焊接参数（例如旋转速度和横向移动速度）对样品的宏观和微观结构，硬度分布和剪切强度的影响。结果表明，通过将横移速度从30 mm / min提高到60 mm / min，并将旋转速度从1000 rpm降低到710 rpm，可以实现更牢固的连接。此外，已经发现，当使用这种方法焊接铜管和铝管时，管的曲率及其物理性质的差异是非常具有挑战性的。
