Zusammenfassung:	An ultrasonic welding device includes a sonotrode emitting longitudinal vibrations in the direction of a longitudinal sonotrode axis which comprises a work surface on a sonotrode head and an anvil. A weldment accommodation for a weld deposit is between the work surface 'p' and a counterface of the anvil. The ultrasonic welding device includes a stop device for defining the welding position with respect to the work surface. The counterface is disposed at an inclination α towards the longitudinal sonotrode axis such that when the counterface is inclined downward towards a vibration node adjacent to the work surface, distance a between the work surface and the counterface continuously increases towards the vibration node, and when the counterface is inclined upward towards a vibration node adjacent to the work surface distance a is essentially constant.
