PROBLEM TO BE SOLVED: To provide a resistance spot welding method attaining excellent welding while preventing the deformation or indentation of metal plates and the occurrence of expulsion or explosion in a pressing process and a welding process.SOLUTION: The resistance spot welding method includes the pressing process S200 for holding a plurality of metal plates W by a first electrode 1 and a second electrode 2 to apply pressing force, and the welding process S300 for causing a welding current to flow to the plurality of metal plates W by the first and second electrodes 1, 2 in a state of applying the pressing force to the plurality of metal plates W. The pressing process S200 and the welding process S300 are carried out while continuously measuring the magnitude of the pressing force. |
