are sandwiched by a pair of electrodes 11 from both upper and lower surfaces, and both contacts 12 are made to straddle the welded portion 15 at the notch 14. When a pair of electrodes 11 are connected to a power source, current flows from the left contact 12 of the upper electrode 11 through the welded part to the lower electrode 11.
The current flows to the right contactor 12 or in the opposite direction as in the above case, so that the weld 15 is heated by this current. This heating temperature can be easily controlled by the strength and time of the current, and it is possible to perform annealing on the butt welded portion 15 in which the hardness can be arbitrarily set. The dust shield 2 as a ring body annealed in this way can be formed by rolling into a desired cross-sectional shape as shown in FIG. 2, thereby preventing cracks from forming in the welded portion 15. be able to.
