Battery welding machine is used for the welding of the negative shell and the electrode, the cylindrical battery (single pin welding Cylindrical cell bottom). Using automatic battery spot welding machine.

battery cell welding machine(Cylindrical cell bottom welding), The currently widely popular AC pulse spot welding machine is controlled by a microcomputer and its performance is more stable and reliable.
It is designed based on the current international production of high-end nickel-cadmium, nickel-metal hydride, and lithium batteries.

The battery welding machine can not only be used for welding cylindrical battery cores, but can also be used for link welding of cylindrical battery packsUltrasonic battery welding is also used in battery welding for cylindrical battery cap welding.
