Abstract: As one of the research hotspots in recent years, nanosecond laser welding (NLW) is considered as one of the important processing means of thin foil components, thermal-sensitive components, microelectronic packaging devices and other small-sized high-performance parts because of its high machining accuracy, low heat-affected zone, high peak power, flexible and controllable processing zone, compared with continuous laser. In this review, the research status of paper publication and patent application of nanosecond laser welding is analyzed at first. Secondly, the mechanism, the metal and non-metal material combinations, the influencing factors and the simulation of nanosecond laser welding are mainly described, respectively. Then, the application of nanosecond laser welding is summarized. At last, challenges and research prospective of nanosecond laser welding are discussed.

Key words: nanosecond laser welding, joint morphology, welding mechanism, process parameters, joint mechanical property
