Spot Welding Copper Sheet

Vehicle manufacturers use resistance spot welding in the factory.
Spot welding copper sheet. 152 4 to 304 8 mm away from the weld. 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. 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. 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.

Resistance spot welding is the joining of overlapping pieces of metal by applying pressure and electrical current. Spot weld anything even copper. To most manufacturers spot welding is the most economical way to join two pieces of sheet metal.
There s hundreds of welding instructables around many of them quite good. 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 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. The theory is simple i ve got a handf.
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. It is often necessary to raise the temperature level of the sheet in an area 6 0 to 12 0 in. 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. 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.
