Abstract
PURPOSE: To make an improvemient of the work efficiency and to make the multiple spot welding capble, further to prepare the yoke of stabilized quality in precision, by operating the welding work of yoke and doubling plate in a method of the projection welding.
CONSTITUTION: In case of securing a yoke 1 to a doubling plate 2, a proturusion 7 is provided in the doubling plate 2. Height ▵t of the protrusion 7 is made 7 to 10 % as high as the plate thickness t, with a diameter D of the protrusion 7 about to 3 x t. Laying the yoke 1 on top of the doubling plate 2, a pressure is applied with the top and bottom face put between electrodes 8, 9, and a work of welding is operated with a current made collectively flowing in the protrusion 7 part. The work of welding and securing, in such manner, can make an improvement of the work efficiency and an operation of the multiple spot welding, with a completed yoke obtainable having a stabilized quality in precision.
