The utility model discloses a welding device of a nickel bar and a bus-bar in a lithium ion battery pack. The welding device comprises a bottom board (1). The top of the bottom board (1) is transversely provided with a base (2). The top of the base (2) is transversely and symmetrically provided with a plurality of magnets (10). The nickel bar and the bus-bar are arranged directly above the magnets (10). According to the welding device of the nickel bar and the bus-bar in the lithium ion battery pack, the magnets are installed so that the nickel bar and the bus-bar can be closely attached to the base, and therefore dependence on flatness of a covering board can be eliminated, the problem of poor welding caused by the fact that the nickel bar and the bus-bar can not be pressed effectively due to thermal deformation of the covering board is effectively solved, welding quality of welding the nickel bar and the bus-bar can be ensured, work efficiency of welding the nickel bar and the bus-bar can be improved, weldi
