In addition, laser welding is less prone to fumes, thereby providing a better working environment and a more environmentally friendly environment for operators. Wherein, the thickness H of the bead structure 30 at the welding of the rim 20 and the spoke 10 is less than or equal to 3 mm.

In the present embodiment, the bead structure 30 is located on the inner surface of the rim 20 and is not directly exposed to the exterior surface of the wheel, so that the wheel has good aesthetic appearance.

Specifically, the welding process of rim 20 and wheel disc 10 is as follows: fixing the wheel to be welded on a fixture, driving the fixture to rotate to drive the wheel to be welded to rotate, so that the spoke 10 is fixedly connected with the rim 20 by the laser emitted by the laser head in a full-welding manner to form the wheel; or fixing the wheel to be welded on a clamp; and controlling the laser heads to rotate around the circumferential direction of the rim 20, so that the laser emitted by the laser heads fixedly connects the spoke 10 with the rim in a full-welding mode, and forming the wheel.

In the present embodiment, the width D of the bead structure 30 is 2mm or more and 10mm or less. Thus, the width setting of bead structure 30 makes the connection strength between rim 20 and spoke 10 higher, and prevents rim 20 and spoke 10 from separating from each other and affecting the service life of the wheel; and on the other hand, the rim 20 and the spoke 10 are easier and simpler to weld, and the labor intensity of workers is reduced.

As shown in fig. 1 and 2, the wheel disc 10 includes a support ring plate 11 and an end plate 12.
