ABOUT INTRODUCTION TO RIVETED JOINTS

 WHAT IS INTRODUCTION TO RIVETED JOINTS?

• Rivet is a short cylindrical bar with a head integral with. It consists of three parts.

        (i)  Head,             (ii) Body or shank, and           (iii)  Tail 

* Rivet Materials :

• The rivet material must be strong and highly ductile. The most commonly used material for rivets is mid steel.
• However, when corrosive resistance or light weight is a requirement and strength is not a main consideration, aluminum, brass, or copper rivets are also used.

* ADVANTAGES AND LIMITATIONS OF RIVETED JOINTS

• Advantages of riveted joints :

1. Unlike welded joints, riveted joints can be used to join dissimilar materials.
2. Metallic as well as non-metallic materials can be  joined by riveted joints.

• Limitations of riveted joints :

1. In riveted joints, the parts once fastened cannot be easily disassembled.
2. The riveted joints are nit as fluid tight as welded joints.
3. The riveted joints weaked the parts to be connected.
4. The complicated components cannot be riveted.
5. The riveted joints cannot be produced at the rate as fast as welded joints.
6. As compared to welded joints, the riveted joints lead to bulky construction.
7. The protuding rivet heads are inconveninent and undersirable in many applications.

• Due to automation and advancement in the field of welding, the uses of riveted joints in engineering applications have been drastically reduced.
• However, in case of material for which reliable methods of welding are not available, riveted joints still remain the fundamental type of permanent joints.
