摘　　要：在对摩擦焊接进行分类并简要说明的基础上,对连续驱动摩擦焊接技术的研究发展和应用现状进行了全面梳理和深入剖析,涉及焊接工艺过程特征和主要工艺参数、工艺探索及工艺参数对接头性能的影响、数值分析和模拟及工艺参数优化、异种金属和非金属材料摩擦焊接与工艺创新、实际工程应用和焊接设备等方面.从摩擦焊接技术的潜在应用、核心科学问题、新型摩擦焊接设备的研发、数值分析和模拟、与新兴技术的结合等方面,对连续驱动摩擦焊接技术进行了评述和探讨.The friction welding(FW)technology is a kind of solid-phase hot pressing welding method applied to the connection of similar or dissimilar materials.During the FW process,welding heat is generated by the pressure and high-speed relative motion between the joint interfaces of the workpieces.After the joint interfaces and their neighborhood arrive at the thermoplastic state,the workpieces are pressed into a whole by upsetting.FW has a wide range of weldability(e.g.,carbon steel,alloy steel,non-ferrous metals,other materials of the same kind,dissimilar metal materials,and metal and non-metal materials with completely different properties)and can obtain welded joints with excellent properties(closed to base metal)and fewer defects(e.g.,cracks,pores,and segregation);thus,it has high reliability to welded joints.As its advantages,FW exhibits low energy consumption(i.e.,10%-20%of fusion welding),high efficiency(i.e.,only a few seconds to realize an effective joining of the workpieces),and environmental friendliness(i.e.,no welding rod,wire,flux,or protective gas and no arc,spatter,smoke,or slag as in fusion welding)and can easily realize automation and large-scale production.FW is widely used in high-tech manufacturing in various industries,including in the automobile,aviation,aerospace,nuclear energy,oil drilling,marine development,and electric power industries.On the basis of the classification and the brief description of FW,the present situation of the research,development,and application of the continuous-drive FW(CDFW)technology was comprehensively sorted out and analyzed in-depth in this paper.This study involved the CDFW process characteristics and main process parameters,process exploration,influence of the process parameters on welded joint properties,numerical analysis,simulations,process parameter optimization,CDFW process innovation for dissimilar metals and non-metallic materials,practical engineering applications,and welding equipment,among others.The aspects of the potential applications of the FW techno
