PROBLEM TO BE SOLVED: To provide a welding method which stably performs joining of an Ni plated steel sheet for a welded can with high quality. SOLUTION: The method for welding an Ni plated steel sheet is characterized in that, when a steel sheet with a sheet thickness of 0.10 to 0.19 mm in which Ni plating is applied to one side by 200 to 1,000 mg/m<SP>2</SP>, and next, a chromate film is applied by 2 to 10 mg/m<SP>2</SP>expressed in terms of metal Cr is welded at a welding wire rate of 55 to 140 mpm, by accelerating the outlet side conveyer of a welding head, the welding speed in one can is increased from the front end to the rear end of the can, and the welding rate at the rear end of the can is increased by 0.5 to 3% compared with the welding rate at the rear end of the can.
