The two-piece type means that the rim part and the spokes are separately forged. The three-piece type means that the spokes and the rim are forged separately. The rim is also forged in two parts. The three-piece rim should be welded and sealed as a whole to prevent leakage. For air, the spokes and the rim should be fixed with screws.

Traditional multi-piece aluminum alloy wheel spokes and rims are connected by laser welding, welding or bolting. Among them, laser welding has the advantages of fast welding speed and high welding accuracy, but there are expensive welding equipment, high energy consumption, and easy welding. Defects and other shortcomings.

The friction stir welding technology is used to weld the rim, which means that the spokes are placed in the rim, and the joint is extruded through the high-frequency rotating welding head, so that the parts are melted and fused under the action of high temperature. At the same time, the joints are connected due to thermal expansion and contraction.
