METHOD FOR PRODUCING AN ULTRASONIC WELDED CONNECTION, WELDING DEVICE FOR CARRYING OUT THE METHOD AND SONOTRODE FOR THE METHOD OR THE WELDING DEVICE

摘要

The invention relates to a method for producing an ultrasonic welded connection to fasten a cylindrical body (1) on a surface (5), wherein ultrasonic vibrations are introduced into a joining zone via an annular working face (9) of a rotationally symmetrical sonotrode (7). In order to make it possible to form weld seams in the immediate vicinity of the cylindrical body, the sonotrode (7) reaches over the cylindrical body (1) and the cylindrical body is accommodated at least partially in a channel (8) formed in the circumferential surface of the sonotrode (7). The invention also relates to a corresponding welding device and to a corresponding sonotrode.
