General 

DIN 8593 describes rivets as non-detachable fasteners for parts of the same or different materials. The connection is accomplished by the deformation of the fastening element (rivet). Riveting is a type of connection which has been tested and approved by Daimler AG and which has significant advantages over inert gas plug welding in terms of corrosion protection following repair work. Deformation of joined parts due to heating does not occur during riveting as connections are made cold. For this reason, the priorities for fastening techniques for repair have been redefined as follows:

• Resistance spot welding
• Riveting
• MAG plug welds and other weld joints

Rivet types, their application and positioning are described in the respective repair documents. For the repair of hybrid construction vehicles, joints are both riveted and bonded. Adhesive bonding achieves higher strength as well as a sealed connection.

For load-bearing sections bonded as standard,  which are not bonded again following accident repair, the number of rivets is specified in the respective repair description. Always observe these specifications to ensure operating stability.

Riveted body flanges must always be sealed with body sealant.

Preparation of rivet points 

Always drill and deburr rivet holes.

To prevent notch effects when riveting and to provide for good plastic flow of the shank in the hole, the edges of the rivet holes should be milled or countersunk.

The connections must be cleaned before riveting.

Ultra-high strength materials 

When processing ultra-high-strength materials, use only high-strength rivets approved by Daimler AG. Only a riveter with increased draw-off strength can be used for this.

Rivet materials 

Basically, the rivet should consist of the same material as the components to be connected or at least a similar material to prevent destruction as a result of electrochemical corrosion or loosening as a result of different thermal expansion.

The primary rivet materials are:

• Steel
• Aluminum alloys
