Differential construction
The differential construction is one of the classic structural assembly techniques in which the relatively simple individual parts are additively connected to one another using a joining technology . This technique is used, for example, in lightweight sheet metal construction by overlapping riveting , gluing and welding .
The opposite of this design is the integral design .
Advantages and disadvantages
Advantages of the differential design:
- Material combinations possible
- easily recyclable
- partial repair possible
- good fail-safe qualities (good failure behavior)
- complex shapes possible
Disadvantages of the differential design:
- Notch effect
- corrosion
- high cost of materials
- high assembly effort
- derived from these disadvantages, there is a higher cost level.
