Energy storage apparatus and inductor tools for magnetic pulse welding and forming

A high-current induction tool assembly for use in a magnetic pulse welding and forming system, said induction tool assembly being effective for generating a high velocity repulsive magnetic force to collapse materials positioned therein, said induction tool comprising:

• a first semi coil having an inner peripheral edge, an outer peripheral edge, an upper end, a lower end and a contact plate at said lower end thereof, said contact plate of said first semi coil being secured in a fixed position;
• a second semi coil having an inner peripheral edge, an outer peripheral edge, an upper end, a lower end and a contact plate at said lower end thereof;
• and
• means for selectively moving and holding said second semi coil into and out of electrical communication with said first semi coil.

• said contact plate of said first semi coil being secured in a fixed position;
• a second semi coil having an inner peripheral edge, an outer peripheral edge, an upper end, a lower end and a contact plate at said lower end thereof,
• said second semi coil being mounted on a first end of a rotatable arm,
• said rotatable arm having a second end in electrical communication with a central electrode of a discharge device,
• said central electrode being rotatable relative to an electrical bus system,
• said arm being rotatably movable for moving said second semi coil relative to said first semi coil;
• and
• means for selectively moving and holding said second semi coil into and out of electrical communication with said first semi coil.
