Joining Route Comparison Filter
Choose the factors that matter to your project. The table filters the questions to investigate; it does not name a universal winner.
Buyer priorities
| Decision factor | Clinching | Self-piercing riveting | Spot welding |
|---|---|---|---|
| Added joining element | No separate fastener in the formed joint | A rivet is added | No separate fastener; electrodes are process consumables |
| Heat at the joint | Cold-forming process | Mechanical insertion process | Localized resistance heat |
| Material requirement | Ductility must suit the stack and tooling | Material and rivet compatibility must be checked | Electrical and metallurgical weldability must be checked |
| Access | Punch and die must reach both faces | Rivet tooling must reach the joint | Electrodes must reach both faces |
| Quality release | Joint geometry plus project-defined testing | Rivet and joint inspection plus testing | Weld schedule, nugget quality and testing |
| Portable setup | May still need air, hydraulics, a battery, hose management or support | Depends on rivet feed and drive system | Depends on power, cooling and electrode system |
