摘要
搅拌摩擦焊虽是一种环保高效的固态连接方法,但在收焊处遗留的匙孔却难以避免,往往需要对匙孔进行修复。本文综述了搅拌摩擦焊匙孔修复技术国内外研究现状,指出了匙孔修复对采用搅拌摩擦焊结构的重要性,为实际生产过程中搅拌摩擦焊缝匙孔修复提供参考。
Friction stir welding is an environmental friendly and effective solid-state joining process. However, the exit hole at the end of the weld is inevitable and needed to be repaired. The research status of the exit hole repairing technology for friction stir welding is reviewed in the present paper. The significance of the exit hole repairing for the friction stir welding structure is pointed out. Reference for the exit hole repairing during actual production process is provided.
