At the end of the conductor arranged with the vertical course, initially a holder is placed surrounding the conductor so that the front side of the conductor is exposed and the point is accessible from the top. After the point of the conductor is in an axial direction, on the front surface a heat source of a temperature from 2000° C. and higher heats the surface. The material of the individual wires surrounding oxide layer are melted or steamed away until all the wires of the conductor including the same surrounding oxide layer form a one-piece combined aluminum composed contact part. After that the contact part together with the end of the conductor is cooled.

Abstract: A method is provided for electrically conductively connecting a contact part on the basis of copper to an electrical conductor composed of a plurality of individual wires containing aluminum. A cup-shaped contact part which has a bottom and a cylindrical sleeve, which is integrally connected to the bottom and protrudes from the bottom, is pushed with tight contact of the sleeve against the conductor to such an extent until the end face of the conductor rests against the bottom of the contact part. Consequently, at least one rotating tool (6) is applied with sustained pressure, until due to increased temperature of the conductor, the conductor is softened to such an extent that it integrally connects with the contact part. The wall of the contact part is not broken through by the tool. Finally, the tool is removed from the contact part.
