Analysis of energy transfer process in magnetic pulse welding …
a reliable connection. Diusion welding [4 ], friction welding [5, 6], and ultrasonic welding [7 ] all belong to the category of solid-state welding, but they have the problems of low production eciency and high investment cost. As a branch of pulse power technology, magnetic pulse welding (MPW) is also a solid-state welding technology. Its

Efficient welding conditions in magnetic pulse welding process
In this paper, the magnetic pulse welding process is studied regarding the efficient welding conditions. The influence of two main controllable parameters, i.e. the charging voltage and the air gap width, on the weld quality is analysed. At low gap a variation of the voltage that contributes to a predominant pression effect does not ...
