A rivet is a cylindrical mechanical joint that has a head. It is used as a member of the joint structure. It is a permanent joint which means that without failure of the machine component it can not be disassembled. This joint interference form fits the parts together. On the two plates, rivets apply a mechanical force that permanently joins the plates. Let us have a deep insight into the pros and cons of riveted joints in this article.
Advantages of riveted joints :
- A riveted joint is more reliable than welded joints in applications which are subjected to vibrations and impact forces.
- Riveted joints can be used for non-ferrous metals like aluminium alloy, copper, brass or even non-metal like plastic and asbestos.
- Riveted joints are free from thermal after-effect because no heat required in this joint.
- Quality inspection is easy in a riveted joint.
- When the riveted joint is dismantled, the connected components are less damaged as compare to a welded joint.
Disadvantages of riveted joints :
- The material cost of a riveted joint is more.
- The labour cost of riveted joints is also more than that of the welded joint.
- Overall cost if the riveted joint is also high.
- The riveted assembly has more weight than the welded assembly.
- The riveting process creates more noise because of hammer blows.
- Holes required to insert rivets cause stress concentration.
- Production time is more for assembly.
- Riveted assemblies are not tight and leak proof.
- The projection of the riveted head adversely affects the appearance of the riveted structure.
