There are several faults that may occur in riveting:
1. Incomplete rivet formation: This fault occurs when the rivet does not completely fill the hole or fails to expand properly. It can weaken the joint and reduce its load-bearing capacity.
2. Over-set or under-set rivets: Over-setting refers to the excessive compression of the rivet, while under-setting is the insufficient compression. Both these faults can negatively affect the joint strength and integrity.
3. Loose rivets: Loose rivets can occur when the joint is not properly compressed, or if there is insufficient tension between the rivet and the materials being joined. This can result in joint failure and reduced strength.
4. Shearing of rivets: In certain cases, excessive loads or uneven distribution of stress can cause the rivets to shear off. This fault can lead to structural failure and endanger the integrity of the assembled parts.
5. Misalignment of rivets: If the rivets are not properly aligned with the holes, it can result in an offset joint, which may compromise the strength and stability of the assembly.
6. Rivet head deformation: Over-pressurizing or excessive force during riveting can cause deformation of the rivet head. This can affect the appearance and fit of the joint, as well as its overall strength.
7. Corrosion: If the rivet or the materials being joined are susceptible to corrosion, it can lead to eventual degradation and failure of the joint.
It is important to use proper techniques, tools, and materials to minimize the occurrence of these faults and ensure a secure and reliable riveted joint.
