Abstract: PURPOSE:To improve the strength of a wheel by performing the correction treatment of the bead contact angle between a welding bead and unweld zone of the joining member beyond the specified angle. CONSTITUTION:A correction treatment is performed by TIG or plasma treatment or grinder treatment on the starting end part 3 and finishing end part 4 of a weld bead 1. First the prescribed range of the starting end part 3 is re-melted by plasma treatment, etc. and the end part of the bead 1 is corrected in smooth sectional shape by moving the fused part to the joining member 2 side. In this case, the correction is performed so as to make the contact angle theta between the weld bead 1 and unweld zone 5 >=130 deg.. The finishing end part 4 of the bead 1 is made similar as well and the correction of the contact angle theta between the bead 1 and unweld zone 5' is performed in the angle of >=130 deg.. Due to the stress concentration of the end part of the weld bead 1 being prevented with this method the strength and durability of the wheel are increased.
