Abstract: Proposed is a resistance spot welding method with which favorable nuggets can be obtained, even adapting effectively to the presence of wear or disturbance of the electrode tip. In the resistance spot welding method for bonding a material to be welded in which multiple metal sheets are stacked, the welding is performed by dividing the current passage pattern into multiple steps of two or more steps. First, prior to the main welding, a test welding is performed for each step, the test welding storing temporal changes in instantaneous heating value per unit volume and cumulative heating value per unit volume, which are calculated from electrical properties between the electrodes when an appropriate nugget is formed by the passage of electric current using constant current control, as target values. Then for the main welding, welding is started with the temporal change curve for the instantaneous heating value per unit volume obtained from said test welding as a reference. When the temporal change in instantaneous heating value deviates from the reference temporal change curve in any step, this difference is compensated for within the remaining welding time for said step by performing adaptive control welding which controls the amount of current passed so that the cumulative heating value for the main welding matches the cumulative heating value determined previously in the test welding.
