The present and future of ultrasonic welding technology











Highest weld quality: Process visualization and process stability provide for product safety and repeatability. Small footprint for easy integration into production lines. Ultrasonic metal welding is the ideal solution for maximum quality in production. For our customers, we assume the role of both consultants and application problem solvers with regard to the ultrasonic joining of nonferrous metals.

In addition to leading-technology battery spot welders and other solutions, we provide excellent, in-depth application services for solving welding tasks, particularly taking into account the qualitative and economic aspects.

Application groups

Lithium-ion batteries (LIB)

A typical lithium-ion battery (LIB) uses copper foil as the anode and aluminum as the cathode. The welding of 20 to 60 foils to each other requires a high level of joining technology from the battery tab welders, with long time process reliability. Burrs or cracks have to be avoided completely.

As more and more products contain rechargeable lithium-ion batteries (LIB), the battery manufacturers are utilizing ultrasonic battery welders as a reliable assembly method. The specifications of the process demand a strong electric contact and no particles on the sealing film of the tab.

Pouch cell and soft cases

Ultrasonic welding for battery soft cases offers an alternative to heat sealing the flexible LIB soft cases. The risk of damaging the cells is minimized by shorter cycle times and the use of cold ultrasonic welding tools as an alternative to hot sealing bars.

Battery management

Rapid development of new energy storage systems increases the necessity for robust framework in modern battery systems. State-of-the-art busbars transfer up to 800 V and require a minimal contact resistance in order to prevent hot spot.
