Abstract (in Japanese) (See Japanese page) 
(in English) Magnetic pulse welding (or electromagnetic pulse welding) of sheets is done by flowing a large discharge current rapidly from a capacitor bank to a flat coil. In order to reduce the large discharge current, using the 8-turn flat coil with large inductance increases current rise time. It may be difficult to weld the sheets efficiently. In this report, after charging the same two sets of capacitors in parallel, they are discharged in series to reduce the bank capacity. The overlapped Al/Cu sheets are electromagnetically welded using the 8-turn coil and the bank of such reduced capacity. The rise time of the current was improved, and efficient welding results were obtained. The bank energy required for this welding was 0.7 kJ and the peak discharge current was about 21 kA.
