Abstract
Provided is a resistance spot welding method whereby expulsion during welding or a reduction in sheet thickness at a weld can be suppressed and delayed fracture of a welded joint can be suppressed. A resistance spot welding method for overlapping two or more steel sheets on each other and electrifying the steel sheets while sandwiching and pressing the steel sheets in a pair of welding electrodes to form a nugget and join the steel sheets, wherein the resistance spot welding method has a main electrification step for forming a nugget part by electrifying the steel sheets with a first electric current I<sub>1</sub> while pressing the steel sheets with a first pressing force F<sub>1</sub> (kN), and a later electrification step for electrifying for an electrification time t<sub>a</sub> (ms) represented by formula (2) with a second electric current I<sub>2</sub> (kA) represented by formula (1) subsequent to the main electrification step and cooling the nugget part, the later electrification step having a first pressing step for maintaining the first pressing force F<sub>1</sub> for a pressing delay time t<sub>b</sub> (ms) represented by formula (3) from the start of the later electrification step, and a second pressing step for pressing with a second pressing force F<sub>2</sub> (kN) represented by formula (4) subsequent to the first pressing step.
