PROBLEM TO BE SOLVED: To provide an electric welding method for measuring the resistance value of the electric heating wire embedded in a joint to set a welding parameter such as the value of voltage applied to the joint corresponding to the region of the resistance value, an energization time or the like to solve a problem wherein the resistance value of the joint is measured erroneously by the welding failure of a connector and a terminal, and electric energy different from that to be applied originally is consequently applied to bring about fuming at the time of welding and welding failure. SOLUTION: An energization time is set corresponding to the region of the resistance value of the joint measured before the start of welding and, after a welding current is once fed, the feeding thereof is stopped to again measure the resistance value of the joint. The supply of the welding current is started only when both resistance values coincide to perform welding. COPYRIGHT: (C)2005,JPO&NCIPI |
