METHOD FOR REPAIRING ELECTROLYSIS CATHODES

摘要

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 bein g electrically connected to at least one supply bar, and of a metal cathode th at 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 a n 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 t he second cutting edge by subjecting the sheet metal to thermal action in an essentially uniform manner.
