摘要
静止轴肩搅拌摩擦焊(SSFSW)作为固相连接领域中搅拌摩擦焊接(FSW)技术的一种重要衍生方法,显著改善了FSW接头表面过热、温度梯度大以及板厚减薄等问题,在轻质合金、低热导率材料、中厚板以及角焊缝等结构焊接中具有巨大的应用潜力。综述了现阶段SSFSW的主要研究进展,涉及SSFSW过程的基本原理、成形特征、微观组织以及力学性能等,以期SSFSW技术形成系统的认知,并展望了其发展前景。
Stationary shoulder friction stir welding(SSFSW)is an important derivative of friction stir welding(FSW)technology in the field of solid state bonding.It can significantly improve the problems of surface overheating,large temperature gradient and plate thickness thinning in the FSWed joints,which shows great application potential in welding of lightweight alloys,low thermal conductivity material,medium plate and fillet welding structure.In order to form a systematic understanding of the technology,this paper summarizes the main research progress of SSFSW,involving the basic principles,forming characteristics,microstructure and mechanical properties,and then make a prospect for the its development.
