摘要：

This paper describes a new seam welding technique and its experimental results. When an impulse current from an energy-stored capacitor bank passes through a flat one-turn coil, eddy currents are induced inside the overlapped ends of two aluminum sheets (thickness 0.5 - 1.0 mm) placed in the coil. The ends can be joined either by the Joule heat generated in them or by the magnetic pressure applied onto them. A bank energy required for seam-welding an area 5x100 mm(2) is less than 3 kJ.
