Spot Welding Copper Sheet

In welding copper sheets the heat is conducted away from the welding zone so rapidly that it is difficult to bring the temperature up to the fusion point.

Spot welding copper sheet.

Vehicle manufacturers use resistance spot welding in the factory. There s hundreds of welding instructables around many of them quite good. 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.

These joints created by resistance spot welding form a button or fused nugget resistance spot welds are found typically on flanges staggered in a single row of consecutive welds. 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. The theory is simple i ve got a handf. 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.

Spot weld anything even copper. The process uses two shaped copper alloy electrodes to concentrate welding current into a small spot and to simultaneously clamp the sheets. Spot welding or resistance spot welding is a type of electric resistance welding used to weld various sheet metal products through a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current. 152 4 to 304 8 mm away from the weld.

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. 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 cd1000dp was set at 310ws energy to weld the 005 copper tab to itself and at 510ws energy to weld 005 copper tab to 010 copper tab. It is often necessary to raise the temperature level of the sheet in an area 6 0 to 12 0 in.
