ALUMINUM CELL CURRENT SUPPLY LEADS CONNECTION METHOD Russian patent published in 2007 - IPC C25C3/16 B22D19/04 

FIELD: methods for connecting by welding electric current supply buses arranged in zone subjected to influence of outer magnetic fields.

SUBSTANCE: additive metal placed in casting mold is heated and melted by means of electromagnetic field of HF current induced by inductor arranged in casting mold or in its lid. Plates of cathode slope portion are stepwise fixed from down to up on cathode bus in the form suitable for connection. Flux is applied onto welded surfaces of parts. Additive metal is cyclically fed to welding zone through metallic disc mounted in outlet opening of casting mold or through valve mounted inside outlet opening of casting mold or from intermediate vessel. Melting temperature of metallic disc is equal to that of additive metal or exceeds it.

EFFECT: high quality of electrical and mechanical welded joints formed in operating electrolysis vessel at condition of outer magnetic fields action without interrupting electric current load of current supply buses and without contamination of atmosphere with combustion products.
