Metal welding | polar materials of battery industry:

We offer a wide range of ultrasonic application technology solutions. Not only can torsional and linear welding be used on flat, diamond-shaped and cylindrical lithium batteries, but also on other products.
For example, the foil poles (positive copper pole, and negative aluminum pole) can be welded on the battery tabs in battery assembly process (soft pack battery) using a longitudinal or torsional ultrasonic welding technique.
