초록 ▼

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.

대표청구항 ▼

1. A method of joining an inner tubular member and an outer tubular member together comprising: inserting a cartridge into a receptacle, the cartridge including a conductor having a first run and a second run that are separated by an insulator, wherein the conductor defines a circumferential gap between an entry port into the cartridge and a reversal point;loading the tubular members into a tool that defines a receptacle for the cartridge; anddischarging stored electrical energy through the first run in a first circumferential direction to the reversal point and through the second run in a second circumferential direction creating an electro-magnetic pulse that joins the tubular members together. 2. The method of claim 1 wherein the stored electrical energy is discharged through the first run and the second run in opposite circumferential directions to create the electro-magnetic pulse joining the tubular members together. 3. The method of claim 1 wherein the conductor is a wire. 4. The method of claim 1 wherein the conductor is a foil. 5. The method of claim 1 wherein the cartridge is formed of a polymeric material. 6. The method of claim 1 wherein the circumferential gap is sufficient to prevent arcing between the entry port and the reversal point. 7. The method of claim 1 further comprising: nesting the tubular members together with overlapping portions of the tubular members being disposed inside the tool. 8. A tube joining method comprising: providing a cartridge defining an opening, wherein first and second conductors separated by an insulator partially extend about the opening;loading the cartridge into a tool;inserting two nested tubular members into the opening; anddischarging stored electrical energy in a first direction through the first conductor to a reversal point and in a second direction through the second conductor creating a circular electro-magnetic pulse that joins the tubular members. 9. The method of claim 8 wherein the stored electrical energy is discharged through the first and second conductors in opposite circumferential directions. 10. The method of claim 8 wherein the first and second conductors are wire segments. 11. The method of claim 8 wherein the first and second conductors are foil strips. 12. The method of claim 8 wherein the cartridge is formed of a polymeric material. 13. The method of claim 8 wherein a circumferential gap is defined by the first and second conductors between an entry point where the first and second conductors enter the cartridge and the reversal point, wherein the gap prevents arcing between the entry point and the reversal point. 14. The method of claim 8 wherein the nested tubular members have overlapping portions disposed inside the tool. 15. The method of claim 8 wherein the tubular members to be joined are cylindrical tubes. 16. The method of claim 8 wherein the tubular members to be joined have a plurality of flat walls.
