Abstract
The invention relates to a method for positioning weldments () in an ultrasonic welding device () and to an ultrasonic welding device comprising a sonotrode (), to which ultrasonic vibrations are applied and which emits longitudinal vibrations, and an anvil (), a weldment accommodation () being formed between a work surface () of the sonotrode () and an opposing surface () of the anvil (), a change in position Δx of a positioning device () defining weld position P of the weldment () being captured in the longitudinal direction () of the sonotrode () by means of a position sensor, the application of vibrations to the sonotrode () being changed such depending on the change in position Δx that a change in amplitude Δy is performed according to an amplitude characteristic curve of the sonotrode ().
