Research progress on electromagnetic pulse welding

With the rapid development of automotive,rail transit,nuclear power,aerospace and other industries,the demand for lightweight connection technology is more urgent. As a reliable dissimilar metal welding technology,electromagnetic pulse welding technology has attracted more and more attention and has become a hot spot in welding technology research. In this paper,the progress of electromagnetic pulse welding technology in recent 5 years in China is reviewed and analyzed. It includes four research directions about the process parameters and joint performance,the development of new technology methods,numerical modeling and simulation technology,joint interface morphology and binding mechanism. The future development of the technology is also forecasted and corresponding suggestions are put forward.
