Copper Wire Spot Welding

There s hundreds of welding instructables around many of them quite good.

Copper wire spot welding.

152 4 to 304 8 mm away from the weld. It is a application of high current and specific clamping pressures and diameters. 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. 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.

Spot welding is a resistance welding process. For a very brief amount of time. I believe some electric components are spot welded. Predominately c101 copper wires were used but some weld trials were also performed with c110 copper wires.

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. To most manufacturers spot welding is the most economical way to join two pieces of sheet metal. 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. The theory is simple i ve got a handf.

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. Spot weld anything even copper. Wires were welded with two geometries referred to as crossed and parallel as described below. All welds were performed on the 3 66 mm faces of c101 copper wire.

It is often necessary to raise the temperature level of the sheet in an area of 6 0 to 12 0 in. Equipment two welding machines were used in this study. While joining sheet metal is the most common use for the process resistance welding rw equipment actually can be used for a large variety of joining and heat treating projects some of which are not so well known. 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.

Copper like other metal parts are.
