Ultrasonic wire welding
Automotive · Electronics
Ultrasonic welding enables the precise and reproducible joining of copper and aluminum conductors as well as various cable and terminal components. Through mechanical ultrasonic vibration, the parts to be joined are bonded together under a defined force without the need for solder or flux.
The process is suitable for various cable cross-sections, conductor materials, and connection geometries. Process parameters such as welding force, amplitude, and welding energy can be specifically adapted to the respective application.
Our ultrasonic cable welding systems are used, among other things, in the Automotive industry, electromobility, power electronics and cable assembly deployed.
Application Range
wire harness to terminal welding
wire-to-wire welding
FPC welding
Double-sided welding
