The magnetic pulse welding apparatus is consisted of a capacitor bank and a gap switch with a flat one-turn coil. These parts form a low-impedance discharge circuit that can generate a high-density magnetic flux around the coil area.The block diagram of the discharge system is shown in the following Figure. When the gap switch is closed, an impulse discharge current from the capacitor bank passes through the coil and the MPW process is started.

The first compact Magnetic Pulse Welding system in our laboratory was design with cooperation of Chuo Seisakusho company for industrial application.
