Abstract
The invention relates to an ultrasound welding process and an ultrasound welding device for securing at least two wire ends located one above the other to contact regions of electrical parts, particularly to contact regions of laminations of commutators for rotating electrical machines or motors, having a sonotrode and having a device for introducing a contact pressure force. It is contemplated that all the wire ends (16, 18) to be secured to at least one contact region (14) are pressed against the contact region (14) by means of the contact pressure force (F), and at the same time the sonotrode (28) sets the lower wire end (16) into oscillation transversely to the contact pressure force (F).
