Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes a copper foil welding technique by using magnetic pulse welding method without drivers and its experimental results. When an impulse current from a capacitor bank passes through a flat one-turn coil, a magnetic flux is suddenly generated around the narrow part (1 or 3 or 5mm in width) of the coil. Eddy currents are induced in two pieces of foil (50μm in thickness) which are overlapped on the narrow part. The pieces of foil can be welded without fusion both by the Joule heat generated in them and by the magnetic pressure applied to them. The bank energy required for seam welding of 25mm in length is less than 2kJ.
