Zusammenfassung:A device to determine a state of an ultrasound welding process, which can be carried out using an ultrasound tool, includes a sensor element and an evaluation unit. The sensor element is configured to detect an electrical control signal from an ultrasound tool. The evaluation unit is configured to determine a signal property of the control signal and to determine the status of the ultrasound welding process based on a reference signal profile and on the determined signal property. An assembly with an ultrasound welding system and a method are also included.
