  • Two-piece wheel
    Patent number: 6769743
    Abstract: A two-piece wheel is formed by joining a center part to a rim part by a friction stir welding. The weld joints are prepared so that at least a portion of a first circumferential weld joint is not parallel to at least a portion of a second circumferential weld joint. Thus, a cast alloy center part may be securely and efficiently attached to a wrought alloy rim part.
