The method for repairing a connecting device for the electrical connection and for supplying and carrying away the coolant to and from the hollow con- ductor elements of the stator winding bars of electrical machines comprises the following method steps: a) removal of the existing connecting device (2) from the bar end by inductive heating; b) cleaning the bar end in the region where the new connecting device is intended to be mounted; c) material-cutting machining of the end surface of the bar end, especially by milling; d) introducing narrow slots (7) between adjacent con- ductor elements (1) into the end of the bar in the transverse direction and vertical direction; e) pushing on a first connecting part (2a) which is made of copper and completely surrounds the bar end; f) filling remaining gaps between the first connect- ing part (2a) and the outer surfaces of the bar end with copper foil and/or solder foil; g) filling the narrow slots (7), which have been introduced into the end of the bar, with copper foil and/or solder foil (10) or a combination of both; h) inductive heating of the first connecting part (2a) and of the bar end and soldering with the addition of solder; - 17 - i) at least visual inspection of the solder joint thus created; j) fitting a second connecting part (2b) made of copper to the free end surface of the first con- necting part (2a) by soldering; k) testing the sealing of the connecting device (2a, 2b) created in this way. This procedure results in high-quality solder joints without having to remove the stator winding. Furthermore, inspection of the soldering is possible at any point in time.
