搅拌摩擦焊 (FSW) 是一种用于连接铝、镁合金的先进固态连接工艺。近年来，它在造船、航空航天、汽车、铁路机车车辆、机器人和个人计算机等领域获得了巨大的应用。在这篇综述文章中，作者重点研究了搅拌摩擦焊过程中不同缺陷的形成。这些缺陷不仅影响焊件的质量，还影响显微组织和力学性能。这些缺陷可以通过优化工艺参数以及合适的工具几何形状来克服。特别是铝铜和铝钢异种材料焊接过程中观察到的各种困难和缺陷
Friction stir welding (FSW) is an advanced solid state joining process for joining Aluminum, Magnesium alloys. In the recent years, it is gaining enormous applications in shipbuilding, aerospace, automotive, railway rolling stock, robotics, and personal computers etc. In this review article, authors are focused on the formation of different defects during friction stir welding. The defects were influence the quality of the weldment and also affect the micro structural and mechanical properties. The defects can be overcome by optimizing the process parameters along with suitable tool geometry. In particular, various difficulties and defects observed during dissimilar welding of the Al-Cu and Al-Steel
