Spot Welding Copper Sheet

The process uses two shaped copper alloy electrodes to concentrate welding current into a small spot and to simultaneously clamp the sheets.

Spot welding copper sheet.

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. Resistance spot welding is the joining of overlapping pieces of metal by applying pressure and electrical current. 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. 14 pack spot weld cutter sets double sided 3 8 hss spot weld cutter remover drill bits hex sheet metal hole cutter remover for power drill spot welding 4 6 out of 5 stars 44 17 98 17.

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. 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. It is often necessary to raise the temperature level of the sheet in an area 6 0 to 12 0 in. 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.

There s hundreds of welding instructables around many of them quite good. To most manufacturers spot welding is the most economical way to join two pieces of sheet metal. Spot weld anything even copper. 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.

Vehicle manufacturers use resistance spot welding in the factory. The theory is simple i ve got a handf. 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. 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.
