Welding as compared to riveting 

Riveting is an old and important technique used to join metals together. But nowadays its area is decreasing due to the developed welding technology.


 Several new methods of welding and soldering have been adopted in today's modern era. The main reason for using different sources of welding is to reduce the cost/time involved in manufacturing the equipment or in the plant.

In today's time, the welding process is being used more than the riveting process, used earlier in bridges, ships, boilers., etc. Similarly, in many fields, the welding process has gradually replaced the riveting process due to time and cost savings.

Welding as compared to riveting and casting         

  • If welding is compared with riveting then it is a more economical and faster method.
  • The use of mild steel has increased in place of cast iron as compared to earlier because it is lighter than cast iron and welding can also be done easily, by this way, it is cheaper and the work gets done faster.
  • In terms of tensile strength, mild steel structures are stronger than cast iron.
  • With the development of advanced welding techniques, it became possible to join metals of two different properties (dissimilar metals) together.
  • It also became possible to manufacture complex structures such as structures with high tension and other desired properties.
  • The most important fact is that Structural shapes that are not easily obtained with riveting or casting can be produced by welding without much difficulty.

Apart from this, many other factors are influential in reducing the popularity of rewriting such as:-

Welding as compared to riveting and casting   

  • There is less noise in the welding process as compared to riveting, this becomes more important when a modification, repair, or extension work has to be done in a sensitive area, such as in a hospital area.
  • Less manpower is used in doing fabrication work through welding as compared to riveting work.
  • Welding fabrication against riveted construction involves a lower cost of handling.
  • The welding design involves low cost and is very flexible as well as saves the machining cost involved in the manufacturing of cast parts.
  •  In this context, the most important fact is that the ratio between the weight of the weld metal and the overall weight of the structure is much less than the ratio between the weight of the rivets and the overall weight of the structure.
  • The cover plate connecting angle gusset plates etc. is not required in riveted construction when welding structures.
  • Such shaped members that present difficulty for riveting can be easily welded.
  • Welding can be done at any point on a structure, but riveting always requires adequate clearance.
  • The layout does not require punching or drilling of holes in welding.
  • Drilling holes in plates to accommodate rivets break the continuity of the material and weakens a riveted structure.
  • Old structures can be easily strengthened by welding.
  • A welded structure processes a better finish and appearance than the related riveted structure.
  • The cost of a standard rolled section is much lower than casting, resulting in lower material costs involved in welded structures.
  • Making changes to an already inserted or riveted structure is extremely difficult, if not impossible. On the other hand, a welded structure can be modified or repaired without any difficulty.
  • Welding can produce a 100% efficient joint that is difficult to make by riveting.
    • Riveting high strength steels increase the problem of obtaining high-strength steel rivets.


While welding claims its supremacy, casting, although it has its good points. such as A product is obtained as one piece, very heavy and bulk parts like those of power plants and mill housings, which are otherwise difficult to fabricate can be cast.
