Mechanical joining techniques have an increasing importance. The automotive industry working within lightweight and high strength is increasingly using materials like high strength aluminium or magnesium alloys.
The advanced lightweight materials require joining techniques without heat input. This means that cold joining techniques are also used more in lightweight automotive manufacturing.
The commonly used mechanical joining processes include:
- Clinch riveting
- Self-Piercing Riveting (SPR)
- Punch riveting
- Blind riveting
