General information
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
- Rivets
- 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.
Gluing achieves higher strength as well as a sealed connection.
Standard bonded load-bearing sections
For standard bonded load-bearing sections which are not bonded again following accident repair, the number of rivets is specified in the specific repair description. Always observe these specifications to ensure operating stability
Always seal riveted body flange with body sealant.
Rivet forms for hybrid construction vehicles
- Various types of rivets
Preparation of rivet points
Always drill and deburr rivet holes.
To prevent that the rivet is notched and to provide for good flow characteristics of the shaft material in the hole, the edges of the rivet holes should be chamfered or countersunk.
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, however, at least a similar material to prevent destruction from electro-mechanical corrosion or looseness by different thermal expansion.
The primary rivet materials are:
- Steel
- Aluminum alloys
Riveting procedure
- Clean connecting points
- Insert rivet
- Pull back pin with hand riveter or electric or hydraulic riveter until it tears off at the predetermined fracture point.
