Abstract: A wheel for a vehicle includes: a wheel rim; a wheel disc; and a laser-welded portion made by joining the wheel rim and the wheel disc by laser welding. In a circumferential direction of the wheel, a total length of the laser-welded portion is equal to or more than 90% of a length of an entire circumference of the wheel disc. The wheel has, between the wheel rim and the wheel disc, at least one non-welded point at which the laser-welded portion is not provided in the circumferential direction of the wheel.

Abstract: A defective product determination method for a vehicle wheel includes: locating, as a locating step by a controller, a lowest point on a welding mark due to radiation of a laser beam within a target range from an inner peripheral surface of a wheel rim to a position spaced away by a specified distance inward in a radial direction of the vehicle wheel; and determining, as a determination step by the controller, that the vehicle wheel is a defective product when a defective product determination condition is satisfied. The defective product determination condition includes, as a necessary condition, a condition that a relative distance of the lowest point with respect to the inner peripheral surface of the wheel rim in the radial direction of the vehicle wheel is equal to or smaller than a reference distance.
