Improving self-pierce rivet performance through processing and alloy development
Spot welding has been used to join steel sheet material in the past during automotive manufacturing. The increasing use of aluminum and mixed materials to achieve continually increasing fuel economy standards requires mechanical joining methods to provide adequate impact performance. One such mechanical joining process is self-pierce riveting (SPR). Self-pierce riveting has grown in popularity in recent years due to fast cycle times, high static strength and fatigue performance as well as the ability to join many different sheet material combinations. Self-pierce rivet utilization has become ...
