ABSTRACT:
A method for ultrasonically welding electrical conductors in which the compaction of the electrical conductors carried out in a compaction chamber takes place in two compaction phases, in which the electrical conductors are first compacted substantially in a vertical direction and thereafter both in a vertical and in a horizontal direction, wherein, during the second compaction phase with superimposed movements, the ultrasonic action takes place for welding the electrical conductors. Several forms of embodiment of an apparatus for carrying out this method and modified methods are described, the common feature of which is the mounting of a crosshead (7), displaceably parallel to a sonotrode surface (2), on a second, vertically displaceable anvil part (8), the crosshead (7) being connected with a drive apparatus (19) acting in its direction of displacement.
