摘要 双轴肩搅拌摩擦作为搅拌摩擦焊的一个重要变体，通过增加下轴肩实现自支撑，使搅拌摩擦焊技术应用于封闭结构（管或中空型材）的焊接。目前，双轴肩搅拌摩擦焊技术的研究与应用仍处于初始阶段，其相关理论研究尚不成熟。针对双轴肩搅拌摩擦焊的研究现状，从双轴肩搅拌摩擦焊方法分类综述了其发展概况，为双轴肩搅拌摩擦焊技术的发展和实际工程应用提供参考。

Abstract：Bobbin tool friction stir welding (BT-FSW) is a significant variant of friction stir welding (FSW). The self-support function is achieved by the lower shoulder of bobbin tool, making FSW easier to join closed structures such as pipes or hollow extrusions. At present, the research and application of BT-FSW are still in the initial stage, and studies
on it are limited. The state-of-the-art of BT-FSW is reviewed based on the realized welding methods. This review provides reference for the further development and engineering applications of BT-FSW.
Key words： Bobbin tool friction stir welding    Stir tool    Temperature field    Microstructure    Mechanical property
