摘要：This paper aims to review the state-of-the-art of ultrasonic vibration assisted friction stir welding (UVAFSW) process. Particular attention has been paid on the modes of ultrasonic exertion, experimental results and effects of ultrasonic vibrations on process effectiveness and joint quality. The trends of various aspects with and without ultrasonic vibrations in FSW process are studied and presented. The influence of ultrasonic vibrations on welding loads, temperature history, weld morphology, material flow, weld microstructure and mechanical properties are revisited. Ultrasonic assisted FSW offers numerous advantages over the conventional FSW process. The superimposing of high-frequency vibrations improves various phenomena of the process and the physical, metallurgical, mechanical and tribological properties of the welded joint. The ultrasonic assisted FSW process has a potential to benefit the industry sector. A checklist listing the materials and process parameters used in the documented studies has been presented for quick reference. ©, 2018, Journal of Harbin Institute of Technology (New Series).
