Abstract
Provided is a resistance spot welding method by which a desired nugget diameter can be stably obtained without expulsion even when the effect of a disturbance is significant. An electrode force Fof a main current passage after an intermediate welding time Tis set based on an average value or time integration value Rof a resistance between electrodes from the start of main current passage to the intermediate welding time T.
