Advantages and disadvantages of riveted joints

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.
