Abstract
A connection (V) of an electrical aluminum cable ( ) with a connection piece ( ) of another metal, especially of copper or a copper alloy, is brought about by crimping the wires ( ) forming the aluminum cable ( ) together in an end region and by welding to the connection piece ( ), especially by a friction welding process. Moreover, the frictional heat between the materials is used to melt the two materials and to join them with each other without additional welding material. The aluminum cable ( ) is provided for this purpose with a support sleeve ( ) crimped upon it, which practically forms the individual wires ( ) at the connection point into a solid surface, which is itself welded to the connection piece ( ). Consequently, connection pieces of copper can be connected tightly and with good electrical conductance, without the danger of corrosion existing in the area of the connection due to various electropositive and electronegative metals.
