Ultrasonic weld technology for thermoplastic materials 

You can book us! Courses are held at Herrmann Ultraschall, at your premises, or in one of our global Tech-Centers.
Seminar appointments by request.



  • Understanding the basic principles of the ultrasonic joining process
  • Getting to know the ultrasonic welding machine and its functional modules
  • Setup and production of an ultrasonic joining application
  • Process-related design of components for ultrasonic weld applications
  • Getting to know other application areas for the ultrasonic welding

Due to the Corona situation, there are currently no on-site seminars. Alternatively, we offer the content as a webinar.
