RAD IN ZWEI TEILEN |
| 摘要 |
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. |
