To solve the welding with powerful magnetic fields in overhauling of cells, a kind of technology and equipment which is used for weakening magnetic induction intensity of welding position just like between collector bar and flex or among the bus bars of 160 ∼ 500 kA aluminum reduction cells in the condition of pot line current was devised. The principle of magnetic field recouped was adopted by the technology. The magnetic induction intensity of welding position can be weakened from more than 100 Gauss to less than 50 Gauss by the technology. According to the technology, magnetic induction intensity weaken equipment which is including magnetic recouped equipment, testing system online of bus bars and expert system of welding process was designed independently by GAMI. Five 350 kA cells have been welded by using the technology and the equipment in Zunyi Aluminum Co., Ltd. and Chinalco Guizhou Aluminum Plant, the welding voltage drop is less than 7.0 mV.
