What’s in a word?
In any context using the word “rivet”, one thing is absolutely clear:
rivet connections are amongst the safest, fastest and most cost-effective processes for the permanent, positive or non-positive connection of several components made of the same or even of quite different materials. The quality of a rivet connection, or of an eyelet or tubular rivet connection, often depends on the technology used. The riveting technique used depends on a wide range of different requirements. The requirements on the rivet connection also determine the selection of the right connection element.
The following questions are typically asked during the selection of the riveting process and connection element:
- Is the component to be riveted a safety component, such as an element in an airbag system, a light alloy brake disc in a vehicle or a safety belt in a fall-protection system etc.?
- Does the rivet or eyelet have a decorative function?
- Should the rivet or eyelet connection be able to be turn?
- Is a positive connection with bearing stress required?
- Can bearing stress forces destroy the components to be riveted or damage them to such an extent that their function is no longer guaranteed?
The requirements determine the processing technology to be used:
- Compressive riveting process
- Wobble riveting process
- Radial riveting process
- Self-pierce riveting technique
- Blind riveting technique
For this reason, specialists should be involved in deciding on the riveting connection to be used.
