PROBLEM TO BE SOLVED: To provide a method for controlling welding-current of resistance welding, which surely prevents the generation of a crack at a bent terminal, and a device therefor. SOLUTION: A device 1 for controlling the welding-current of resistance welding is composed of: a welding power source 2, an electrode 3, a temperature sensor 4 (a temperature measuring means), a current sensor 5, and a current controller 6 (a welding-current controlling means). The current controller 6 controls the welding-current based on the measurement result of the temperature sensor 4. Thus, the generation of a crack at a connecting part 7d of an almost U-shaped terminal 7a is surely prevented. COPYRIGHT: (C)2005,JPO&NCIPI
