Answer 1

Riveting is the process of fixing a mechanical fastener havindhone side cylindrical head known as rivet to the metal sheets with the help of force .

Spot welding is electric resistance welding technique contact metal surface points are joined by the heat obtained from resistance to electric current.

Advantages of rivets over spot welding.

1.Riveting is a cheap process as it does not require electricity like in spot welding.

2.Rivets can be manufactured in required size and shape so they have more flexibility.

3. Maintenance and inspection is easy in riveting.

4. No distortion of material in rivetting.

5. Similar thickness diverted joint carry more ultimate load.

Disadvantage of Riveting over spot welding..

1.Rivetting require more work force.

2. Rivetting causes high structural weight

3. Efficiency of rivetting joint is not as equal to base metal.

4. Rivetting structure looks rough but spot welding looks finish.

5.Rivetting can not be done in each position of the product.

6.Rivetting require more time than welding.
