Patent attributes
An opposed current flow magnetic pulse forming and joining system in electrical communication with a magnetic pulse power supply having a positive connection and a negative connection. The system may be used in forming individual workpieces or joining multiple workpieces, including joining by magnetic pulse welding. The system includes a first section, a second section, an insulator, and a first and a second pair of conductors. The first and second sections cooperate to enclose the workpiece(s) and function to create an electromagnetic force similar to that produced by a single closed coil. The system is configured to achieve desirable current flow by minimizing inductance, inductive reactance, and impedance in the conductors. The pairs of conductors may incorporate closely spaced individual conductors, braided conductors, and coaxial conductors. The current flow in the individual conductors of each pair of conductors is opposed, as is the current flow through the sections.
