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.
There s hundreds of welding instructables around many of them quite good.
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.
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.
To most manufacturers spot welding is the most economical way to join two pieces of sheet metal.
Resistance spot welding is the joining of overlapping pieces of metal by applying pressure and electrical 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.
152 4 to 304 8 mm away from the weld.
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.
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 process uses two shaped copper alloy electrodes to concentrate welding current into a small spot and to simultaneously clamp the sheets.
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.
