The invention relates to an ultrasonic welding tool for producing a welded seam for connecting at least two thermoplastic materials (F1, F2) comprising a tool body (11; 21) having a working surface (12; 22), by which the thermoplastic materials (F1, F2) can be contacted for producing the thin welded seam (S). According to the invention, a number of embossments (14; 24) arranged in parallel are present on the working surface (12; 22) of the ultrasonic welding tool (10; 20), separated from each other by intermediate spaces (13; 23). |
