摘　　要：继激光焊后,搅拌摩擦焊成为具有革命性的焊接技术。因焊接温度峰值低于材料熔点,搅拌摩擦焊可避免常规熔化焊所产生的热裂纹、大变形和组织粗大等缺点。对搅拌摩擦焊接技术进行了全面系统的介绍,主要包括焊接原理、焊接设备、焊接工具、可焊材料、焊接接头形式及焊接接头静载/动载性能等。对由搅拌摩擦焊演变而来的常规搅拌摩擦点焊、回填式搅拌摩擦点焊也进行简单介绍。最后对搅拌摩擦焊技术在航空航天、汽车、轮船等领域的应用进行介绍和展望。Friction Stir Welding（FSW）is regarded as a revolutionary joining method to replace laser beam welding. In view of the lower peak temperature compared to the melting point of materials during welding process, FSW technology can avoid the disadvantages （e. g. hot crack, large deformation and coarse micro- structures） caused by traditional fusion welding technology. FSW technology was introduced comprehensive- ly and systematically in this paper, mainly including welding principle, welding equipment, welding tools, welding materials ,joint form and static/ kinetics mechanical properties. Friction stir spot welding （FSSW） and refill friction stir spot welding （RFSSW） evolved from FSW were also presented briefly. Finally, some applications of FSW in the fields of aerospace, automobile, shipping were stated.
