description: The given work is devoted to the development of a device for ultrasonic welding with using digital signal processing. The research set the following goals:
1. The resonance search algorithm.
2. Algorithm for adjusting the resonance frequency during operation.
3. Frequency control of direct digital synthesizers.
4. Schematic diagram of the device.
5. Prototype circuit board.

To date, the existing equipment for ultrasonic welding has a number of disadvantages, because of which the efficiency of such devices is small. In the course of the work, these shortcomings were described and a device was proposed that can significantly increase the efficiency, and with the help of a microcontroller and digital signal processing we get such advantages as analogs: a convenient control interface, autonomy, flexibility and a significant simplification of the device circuit for this type of welding.
As a result of the work, the following were presented: resonance search algorithms, an automatic frequency control algorithm, a circuit diagram of the device, as well as a prototype of a printed circuit board.
