Customer ServiceIn summary, welding the thicker, more conductive tabs used in today’s more efficient, higher capacity battery packs can be challenging, but welding success can be achieved by designing the parts correctly and selecting equipment that is best suited to the application.
Safety is another concern when selecting resistance welding equipment for battery welding. For example, if not welded properly, the chemicals contained in lithium ion batteries (you’ve heard about this in the news recently, associated with the new Boeing 787 aircraft) can leak out, burning eyes and skin.
Whether to power our latest portable electronic device, power tool, or hybrid/electric vehicle, the removable battery pack is essential to our everyday lives. Tab-to-terminal connection is one of the key battery pack welding applications.
It features 5kHz fast feedback, and operates in constant current, voltage or power feedback modes. Voltage feedback is the typical mode of choice when welding battery packs, but the IPB-5000A can also weld in “combo mode” (current and voltage) to address even the most challenging battery welding applications.
Add slots and projections to the tab design to focus the current and minimize current shunting. Welding success also depends, in part, on the battery itself; those with thick caps can easily handle the high force and current needed to weld the thicker tabs. If the battery caps are too thin, however, they may get deformed or blown through.
This therefore provides a highly controlled method of developing localised welding temperatures that are suitable for joining materials up to 0.5 mm thick onto conductive battery cans. The TIG battery welding process has been tested and proven with a number of battery pack designs using nickel, aluminium and copper flat.
