摘要
由英国焊接研究所发明的搅拌摩擦焊可用于金属结构中缺陷的修复。与传统的熔化焊相比,搅拌摩擦焊修复具有高质量、低能耗、低成本、绿色无污染等优点。近年来,国内外的专家和学者不仅对裂纹型缺陷的修复进行了研究,还提出了多种由搅拌摩擦焊演生而来的工艺进行了体积型缺陷的修复。在介绍搅拌摩擦焊原理的基础上,对搅拌摩擦焊进行缺陷修复存在的工艺问题进行了分析,重点介绍面积型与体积型缺陷的修复工艺研究现状。
Friction stir w elding（ FSW） invented by The Welding Institute can be used to repair the defect in metal structure. FSW repair has the advantages of high quality,low energy consumption,low cost and nonpollution compared to the conventional fusion w elding. In recent years,researchers at home and aboard have investigated not only crack repair by the conventional FSW process but also volume defects by some new processes evolved from FSW. In this paper,FSW principle w as introduced,and then technological problems on defect repair using FSW w ere analyzed. Research development of FSW repair to planar and volume defects w ere presented in detail.
