摘要： 　搅拌摩擦焊是一种高效环保的固相连接方法，具有温度低、塑性变形剧烈和接头质量高等特点，可有效解决熔焊在石油储存罐及管道焊接存在的问题。但是，其受焊接参数、工况及该方法固有模式的影响，搅拌摩擦焊存在焊接缺陷，降低接头服役寿命。总结了搅拌摩擦焊缝存在的两大类主要缺陷（贯穿型和区域型），包括特征和诱因，并重点综述了各种缺陷的高质修复技术，对接头性能改善、高效高质缺陷修复与工程化应用具有重要的指导意义。

Abstract: Friction stir welding (FSW) is an effective, environment⁃friendly solid state is an efficient and environmentally friendly solid phase bonding method, which has the characteristics of low temperature severe plastic deformation and high joint quality. FSW can effectively solve the problems associated with fusion welding in petroleum tanks and pipelines. However,due to the influence of welding parameters, working conditions and inherent mode of the method, friction stir welding has welding defects, which reduces the service life of the joint. The two major welding defects (global and local welding defects) were summarized in terms of characteristics and causes, while the repairing technologies for various defects were reviewed. This paper has practical significance for joint quality improvement, high⁃efficiency high⁃performance repairing and engineering applications.

Key words: Petroleum pipeline, Friction stir welding, Defect, Solid state repairing technology
