    Publication number: 20130337284
    Abstract: A resistance welding method according to the invention includes: a melting start time specification process for specifying a melting start time, which is a time at which at least a part of a welding portion of a welding subject starts to melt while being subjected to Joule heating by a power input from an electrode pressed against the welding subject, by detecting a variation in an ultrasonic wave emitted toward the welding portion; a first power amount calculation process for calculating a first power amount, which is an integrated value of the power input into the welding subject via the electrode from the melting start time; a first determination process for determining whether or not the first power amount has reached a first set value; and a heating process for performing the Joule heating from the melting start time until the first power amount reaches the first set value.
