Abstract
Provided is a spot welding method by which welding can be successfully performed while inhibiting occurrence of expulsion. First to third metal plates Wto Wwere welded in which ratio of total thickness to thickness of the first metal plate Wis 7. In Example 1, peak current value Ais 14.6 kA, effective current value Ais 7.8 kA, peak duration Tis 0 ms, and no-peak duration Tis 5.9 ms. As a result, in Example 1, lower limit current value Ais 6.9 kA, upper limit current value Ais 8.42 kA, difference Abetween upper limit current value Aand lower limit current value Ais 1.52 kA, peak duration T/no-peak duration Tis 0, effective current value A/peak current value Ais 0.53, and rising time T/falling time Tis 0.79, furthermore, no expulsion occurs, and welding result was determined to be OK.
