Abstract
Magnetic pulse welding differs from explosive welding only by sources of energy for sheet acceleration: magnetic field energy is used instead of explosion energy. Magnetic field interaction with the sheet 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 sheet buckling, which impose constraints on using magnetic pulse welding. These constraints are associated with geometric parameters of the welded sheets 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 sheet acceleration. A new pioneering scheme of magnetic pulse welding of more than two sheets is developed.
