Copper Wire Spot Welding

For a very brief amount of time.

Copper wire spot welding.

All welds were performed on the 3 66 mm faces of c101 copper wire. Resistance spot welding is a thermo electric process where heat is generated at the interface of the parts to be welded by passing an electrical current through them for a precisely controlled time and under force. The theory is simple i ve got a handf. 152 4 to 304 8 mm away from the weld.

We offer a wide range of precise welding solutions driven by servo for annealed non ferrous metals including copper aluminum and tinned tin coated wire splicing wire compaction wire ring termination wire to terminal welding reel feed terminal welding large cable termination lithium ion foil to foil foil to tab tab to lead foil to bus bar tab to busbar cylindrical 18650 pouch. Copper is a highly conductive metal often used as the metal of the conducting electrode ends of spot welders complicating the process of spot welding it. Spot weld anything even copper. Copper like other metal parts are.

Spot welding is a resistance welding process. Spot welding copper requires special electrodes and brazing paste in order to achieve the same sturdy welding job that can be more easily achieved with metals such as steel. Wires were welded with two geometries referred to as crossed and parallel as described below. Equipment two welding machines were used in this study.

To most manufacturers spot welding is the most economical way to join two pieces of sheet metal. It is a application of high current and specific clamping pressures and diameters. Predominately c101 copper wires were used but some weld trials were also performed with c110 copper wires. The process involves applying pressure and heat to the weld area using shaped alloy copper electrodes which convey an electrical current through the weld pieces.

It is often necessary to raise the temperature level of the sheet in an area of 6 0 to 12 0 in. There s hundreds of welding instructables around many of them quite good. A form of resistance welding spot welding is one of the oldest welding processes whereby two or more sheets of metal are welded together without the use of any filler material. I believe some electric components are spot welded.

I m writing this one here to share a technique i ve developed that works quite well even on copper tabs for which it was designed.
