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

摘要

An energy storage system for use in a magnetic pulse welding and forming apparatus includes a bank of capacitors and a very-low inductance conductive bus system interconnecting the capacitors. The bus system provides the ability to generate a very high frequency, short duration impulse which is needed for welding. The energy storage system further includes an energy source connected to the capacitors, a discharge device, a charging control device, and a discharge control device for selectively initiating discharge of energy stored in the capacitors. Inductor tools used in connection with the energy storage system are split to allow parts to be welded to be easily mounted into and removed from the inductor tools. One part of the split inductor tool is either rotatable or slidably movable relative to a fixed part of the inductor.
