Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a resistance welding control method capable of obtaining excellent welding quality even when the state of a weld zone is abnormally fluctuated in the resistance welding control method to control the temperature pattern follow-up current to increase/decrease the welding current value so as to substantially follow the temperature change target pattern predetermined by the estimated value of the weld zone temperature by estimating the temperature of the weld zone during the resistance welding by the heat conductivity calculation. SOLUTION: In the resistance welding control method, the resistance welding is performed again at the spot welding position if the maximum value Tm of the estimated temperature of a weld zone is below the predetermined reference maximum value Tt and/or if the average value Ia of the energized welding current value is below the predetermined reference average value It when the welding at one spot welding position is completed.
