Abstract
A method and an apparatus for ultrasonic welding of a first workpiece to a second workpiece is disclosed. The two workpieces are clamped between a sonotrode and an anvil so that the two workpieces are in mechanical contact with each other, the first workpiece is in mechanical contact with the sonotrode and the second workpiece rests on the anvil. Fluid is introduced between the second workpiece and the anvil so that the second workpiece at least partly rests on the fluid. Ultrasonic vibrations are applied to the first workpiece by the sonotrode for a period of time.
