What is Resistance Welding?
Resistance welding is the science of joining two or more metal parts together in a localised area by the application of heat and pressure.
The heat is produced by the resistance of the material to carry a high amperage current.
The greater the path of resistance is, the higher the heat intensity.
This heat is controlled via time application and level of current applied.
The pressure is applied to forge the joint and consolidate the nugget to provide the weld strength.
No extraneous materials such as rods, fluxes, inert gasses, oxygen, or acetylene are required.
Battery Tab Welding
Resistance welding in parrallel passes the current between the two top electrodes, which flow through from one side of the battery terminal to the other side of the same terminal. No current flows through the battery.
Heat affected zones are created at the boundary where the tab rests on the battery due to the dimples on the tab. The heat generated due the electrical resistance creates the weld at each point.
