<P>PROBLEM TO BE SOLVED: To provide lap resistance welding and a device for the same capable of achieving an improvement in efficiency, energy saving, reduction in cost, improvement in quality with novel ideas, in lap resistance welding, and to enable welding of an article to be welded, which is conventionally thought to be unsuitable for the lap resistance welding. <P>SOLUTION: In this method, the resistance welding is performed by changing a pressurizing force before and after energization for welding of the article to be welded. The energization is started in accordance with acquisition of information on a change in the pressurizing force from at a pressurizing stage before the welding to at a pressurizing stage for the energization, and a change from the pressurizing stage for the energization to a pressurizing stage after the energization is made in accordance with acquisition of information on that the energization is completed or the energization amount reaches a certain amount. <P>COPYRIGHT: (C)2012,JPO&INPIT |
