Abstract

The invention relates to a method for repairing electrolysis cathodes that, together with anodes in a galvanic bath provided for carrying out a galvanic electrolysis, are connected to a power source. The electrolysis cathodes are comprised of a crossbeam, which is arranged above the galvanic bath for being electrically connected to at least one supply bar, and of a metal cathode that projects into the galvanic bath. At least one portion of the cathode sheet metal is detached from the crossbeam by subjecting it to thermal action in an essentially uniform manner in the area of a first cutting edge. In order to provide a second cutting edge, a replacement sheet metal is cut to size at least in the area of an extension, which can be turned towards the crossbeam, by subjecting it to thermal action in an essentially uniform manner. The replacement sheet metal is welded to the first cutting edge in the area of the second cutting edge by subjecting the sheet metal to thermal action in an essentially uniform manner.
