Method for welding electric conductor by ultrasonic waves and ultrasonic metal welding device

摘要

The present invention is an ultrasonic metal welding device and compression that is at least adjustable in height and delimited at opposite sides by a section of the sonotrode as the first interface and at least one section of the counter electrode 156 as the second interface. A method of welding an electrical conductor using a chamber, for welding, the counter electrode and the sonotrode are displaced relative to each other. The counter electrode used is an electrode comprising sections 152, 154 of different geometrically different working surfaces or consisting of at least two sections displaceable relative to each other.
