Pulse Joining Cartridges

摘要

A pulsed joining tool includes a tool body that defines a cavity that receives an inner tubular member and an outer tubular member and a pulse joining cartridge. The tubular members are nested together with the cartridge being disposed around the outer tubular member. The cartridge includes a conductor, such as a wire or foil, that extends around the outer tubular member and is insulated to separate a supply segment from a return segment. A source of stored electrical energy is discharged through the conductor to join the tubular members with an electromagnetic force pulse.

1. A pulsed joining tool comprising:
a tool body defining a cavity for receiving two nested tubular members; a cartridge disposed in the cavity including a supply conductor and a return conductor extending circumferentially from an entry point to a reversal point with electrical insulation isolating the supply and return conductors; and a source of stored electrical energy dischargeable through the supply and return conductors to join the tubular members.
