Permanent blind rivet assembly for structural elements
|
|
Arc welding:
- not very flexible welding process
- high level of material heating
- workpiece deformation
- scarcity of qualified arc-welders
- an unattractive solution (weld spots)
Spot welding or seam welding:
- a welding process that is not very flexible
- variable and non-guaranteed assembly resistance levels
Hollow Rivet:
- blind installation is impossible |
