Abstract
In a device for joining two components (8) by means of ultrasound, consisting of an ultrasound generator (3) and an ultrasound system (1), whereby the ultrasound system (1) comprises an ultrasonic welding device (9) with a converter (10) and a sonotrode (11), a constant welding quality is obtained by the fact that the ultrasound system (1) is provided with a temperature measuring unit (15) which measures the temperature of the welding point (14) and/or the temperature of the sonotrode tip (16), and that the temperature unit (15) is linked to a control unit (2) which controls the ultrasound generator (9).
