Abstract
Magnetic-pulsed welding differs from explosive welding only by sources of energy for plate acceleration: magnetic field energy is used instead explosion energy. Magnetic field interaction with the plate has some specific features associated with the value of energy stored in the battery, the rate of heating to the melting point, and the possibility of plate buckling, which impose constraints on using magnetic-pulsed welding. These constraints are associated with geometric parameters of the welded plates and the gaps between them; the critical values of these parameters are obtained in the present study. A capacitor battery is used in the experiments for plate acceleration. A new pioneering scheme of magnetic-pulsed welding of more than two plates is developed.
