PROBLEM TO BE SOLVED: To provide an electric resistance welding method and its equipment that can reduce welding time by rationally correlating transfer of a steel plate component with the supply of components. SOLUTION: A steel plate component 13 is made to stop between a pair of electrodes 6, 7, and then, a component 9 supplied to and held by one of the electrodes is welded by electric resistance welding at a prescribed position of the steel plate component 13 through the advance of both electrodes 6, 7. After the retreat of both electrodes 6, 7, the steel plate component 13 is transferred between both electrodes 6, 7 to the next welding position and prepared for the next component welding. Then, nearly concurrently with the transfer of this steel plate component 13, the next component 9 is supplied to one of the electrodes. Thereafter, the next component 9 is welded to the steel plate component 13 by the advance of both electrodes 6, 7. COPYRIGHT: (C)2008,JPO&INPIT |
