A welding set up used for welding tabs to the battery is actually an implementation of a contact welder. This means tat the two systems share a lot of features and parts. In fact, in some cases, the implementation is so similar that parts could be interchanged without any problem.
One of the most important features of battery tab welder is the shape of electrodes. Since electrodes play an important part in the welding process. The electrodes used in these machines should be carefully selected. The mot common shape is the parallel-pronged electrodes that deliver a timed pulse of energy accurately.
Welding the tabs on batteries is a specialized application of the spot welding process. This process use nickel-plated steel tabs that require very specific parameters for correct joint. Typically, the thickness of these tabs is 0.15 mm. this is taken as the standard thickness of the tab. A majority of battery tab welders use this as the standard of the tabs.
Given the delicate measurement of the tabs used for batteries. It is easy to see that the standard contact welding machines are not suitable for the task. The energy delivered by these machines is somewhere around 4000 A. this is enough energy to severely wrap the tabs.
The operational parameters of battery tab welder are very restricted as compared to other spot welding applications. The operational current is 1100 A. his is enough to ensure a secure weld without damaging the tab. If too high current is used, there is a real possibility that the battery could explode.
The weld electrodes are spaced at least 5mm apart. This is usually used for parallel prong electrodes. The result is a double weld that is more permanent than a single spot weld. The electrode arm applied a pressure of 4N to complete the weld.
