アルミニウム箔と各種金属箔の電磁シーム圧接 Magnetic pressure seam welding for aluminum and various metal foils
This paper deals with a new foil welding method 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 in the coil. Eddy currents are induced in two insulated metal plates and overlapped foils (for example, aluminum and copper) between the plates in the coil. These foils could be welded both by the magnetic pressure applied onto them and by Joule heat generated in them. The bank energy required for welding of 20 mm in length was less than 2 kJ.
