Advantages and Disadvantages of Riveting
Read: What is Riveting ? Applications of riveting
Advantages of riveting
- Relatively inexpensive method. The production of the rivet is cheap.
- Rivet can be used in joining of ferrous as well as a nonferrous metal like aluminium and copper alloys.
- Rivet can be used in joining of nonmetallic material like wood, plastic, asbestos sheet etc.
- One of the main advantages of the rivet is that it can use to join dissimilar materials. (eg: joining aluminum plate and copper plate).
- Ability to make joint regardless of the location. (Vertical, overhead, etc.)
- No fumes and gases produced as in the welding, the production is environmentally as well as user-friendly.
- Riveted joints are reliable than other methods in applications where the joint subjected to excessive vibration and impact forces.
- High shear strength, good fatigue resistance.
- Aluminium rivets are lighter than bolt and screws. They also possess high resistance to atmospheric and chemical corrosion.
- Since there is no melting of metal and uneven heating and cooling involved while joining process, thermal effects on the riveted joints are minimum. So it causes little or no damage to protective coatings of material.
- The quality inspection of the riveted joint is easier than the welding inspection.
- Dismantling of riveted joint cause less damage when compared to welded joint.
Limitations of riveting
- Riveting take more labor time than welding. Additional operations like lay out and drilling holes are necessary. The labor cost of rivet joints is high.
- Stress concentration at the rivet holes of metal plates.
- The holes may weaken the working cross section of the plate. Then the additional thickness is required to compensate for this problem. This additional thickness and overlapping of plates for riveting increases metal consumption.
- It has more weight than welded joint due to strap-plate and rivets.
- The riveted joints are bulkier than welding and brazing. The projection of rivet also affects aesthetic appearance.
- They typically do not make a tight or leak-proof joint unless using hot rivet or sealant along the rivet.
- The riveting process is noisier than welding due to hammer blowing.
