| 摘要 |
The invention relates to a connecting element (1) for a friction weld connection for connecting at least two plate-like components (8, 9), having a centering part (4) for centering and guiding the connecting element (1) subjected to rotation and pressure during penetration of the upper component or components (8) by a mandrel (2), the length thereof being adapted to the thickness of the upper component or components (8). The centering part protrudes as a pin (4, 13 16 18) from a substantially flat cross-sectional area of the mandrel transitioning into the friction weld connection and is formed so short and thin relative to the length of the mandrel that, after penetrating the upper component or components, the material of said centering part softens and the centering part thus practically completely transitions into the friction weld connection. |
