摘　　要：熔焊焊接时会不可避免地出现侧壁不熔、咬边、晶粒粗大等问题,导致接头性能较低。为更好地解决焊接中存在的问题,提出旋转电弧焊接技术。相对于普通焊接,旋转电弧中的旋转电弧耦合力在焊接时对熔池的搅拌破碎效应能加速焊缝中的传质传热,并细化晶粒减小焊缝残余应力,能解决焊接中常见问题,获得优质焊缝并提高焊接接头的使用寿命。主要综述了基于外加磁场、非对称钨极旋转电弧、缆式焊丝熔化极旋转电弧的研究现状,指出目前旋转电弧焊接技术还存在的问题,并对相关技术的应用前景进行展望。Fusion welding is the most widely used connection method and the most mature welding technology in industrial production.The use of fusion welding welds will inevitably result in problems such as non-melting sidewalls,edge gnawing and coarse grain size,resulting in lower joint performance.In order to better solve the problems in welding,rotary arc welding technology is proposed.Compared with ordinary welding,the rotating arc coupling force in the rotating arc can accelerate the mass and heat transfer in the weld by the stirring and crushing effect on the molten pool during welding.And refine the grain to reduce the residual stress of the weld,can solve the common problems in the welding,to obtain high-quality welds and improve the service life of the welded joints.The article mainly reviews the current research status of welding technology based on applied magnetic field,asymmetric tungsten electrode rotating arc,and cable-type wire melting electrode rotating arc.It points out the problems that still exist in the current rotary arc welding technology,and looks forward to the application prospects of the related technology.
