RESISTANCE WELDING DEVICE, RESISTANCE WELDING METHOD, AND SHAPE OF PROJECTION FOR PROJECTION WELDING

摘要

PROBLEM TO BE SOLVED: To provide a resistance welding device and a resistance welding method in which joining quality can be determined, and a shape of a projection to be used in projection welding and is suitable for determining joining quality or the like, and thereby improve electrical reliability and mechanical joining strength of conductor connection of an electric power steering device.;SOLUTION: A movement amount measuring part 1007 is disposed in a resistance welding device 1000, and an interval between conductors 1004 and 1005 to be joint is measured before and after joining them. In order to evaluate joining quality on the basis of the interval, and to facilitate securing an interval between the conductors after joining them, a projection 200 constituted of a base 210 and a projection face 230 is provided on the conductor 1005 to be connected.;SELECTED DRAWING: Figure 6;COPYRIGHT: (C)2017,JPO&INPIT
