WELDING DEVICE AND METHOD FOR WELDING WORKPIECES

摘要

The invention relates to an ultrasonic welding device which comprises a plurality of elements that adjoin each other via coupling surfaces in a non-positive manner. In order to obtain a sufficiently firm connection between the elements while at the same time simplifying their assembly, the superimposed coupling surfaces (40, 42) of at least some of the elements (30, 34) that are linked in a non-positive manner are structured, thereby obtaining a positive connection.
