The cathode busbar connection of the aluminum electrolytic cell often adopts a series of power outage; current reduction and shielding for welding due to great influence of the magnetic field, which is unable to ensure welding quality, causes the unbalanced current distribution, and leads to unstable production, high energy consumption, serious pollution, and even causes the reduction of production. In order to solve the above problems, the technology, equipment for magnetic reduction and welding in aluminum electrolysis cell and welding robots have been developed. This paper mainly describes research and development on the technology and equipment for magnetic reduction and welding in aluminum electrolysis cell from technical principle and route of the equipment, mechanical design and structural optimization of drainage magnetic compensation device, design of robot structure and robot mobile trolley. In addition, the paper mainly introduces structure of high capacity rheostat.
