Abstract

Method for manufacturing an electrically effective point of contact on the end of an electrical conductor with a plurality of stranded wires composed of aluminum or an aluminum alloy. 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.
