Riveting and welding have been around since the beginning of metalworking. They both require the use of heat to fuse two metal parts together and are considered permanent, strong joints. However, they are very different processes with different costs, strengths, and weaknesses.
There are many ways to join metal parts, but which is the best? Riveting and welding — are both great ways to achieve a secure connection, but the processes are quite different. Here’s a closer look at each of the two joining methods.
Today, we’ll be comparing riveting and welding to help you better understand when to use each of them in your next project.
What is Riveting?
Riveting is a common sheet metal fabrication process where two metal parts are joined together using heat and pressure. A small hole is drilled into each of the parts to be joined, and then a rivet (a metal rod with a head on one end) is placed into the holes. The ends of the rivet are then hammered down, which fuses the two pieces of metal together. Riveting is a very strong joint that can withstand a lot of force and vibration.
One advantage of riveting is that it does not require any special skills or equipment – just a drill, some rivets, and a hammer. Riveting is also faster than welding, which can be important when tight times. However, riveted joints are not as strong as welded joints, and they are more difficult to repair if they break. Riveting is also limited to joining smaller pieces of metal; larger projects will need to be welded instead.
What is Welding?
Welding joins two pieces of metal together by melting them and fusing them together. This process requires specialized equipment and skills but results in a stronger joint than either riveting or bolting. Welding can be done with many different metals, including steel, aluminum, brass, and even some plastics.
There are several different types of welding: MIG welding (inert metal gas), TIG welding (inert tungsten gas), Plasma Arc Welding (PAW), and Oxy-Acetylene Welding (OAW). Each type has its own advantages and disadvantages; for example, MIG welding is fast but produces less precise joints than TIG welding. OAW requires expensive equipment but can weld metals that other methods cannot weld effectively.
Differences Between Welding and Riveting
1. Welding is a fusion of metals that are heated together to create a solid bond between them. In welding, two pieces of metal are brought together and melted at their interface. When they cool down, the molten material forms a strong joint.
2. Riveting is a joining technique where two pieces of metal are joined using a mechanical fastener. A rivet is used to join two pieces of metal together. The head of the rivet is placed into the first piece of metal and then the second piece is pushed over the top of the head. Once both pieces have been put together, the rivet is hammered down until it makes contact with the bottom surface of the first piece.
Weld joint vs Rivet Joint
3. Both welding and riveting require heat to fuse the metals together. However, welding requires much higher temperatures than riveting. This means that welding can only be done with certain types of metals. On the other hand, rivets can be used to join any type of metal.
4. Welding uses filler metal to fill in gaps between the parts being welded. Filler metal is added to the area where the weld is going to take place. Because welding creates a large amount of heat, the filler metal melts and flows into the gap.
5. Riveting does not use filler metal. Instead, it relies on the pressure from the hammer to push the rivet through the two pieces of metal.
6. Welding is usually performed manually, while riveting is automated. Manual welding takes longer than automatic riveting.
Comparison Between Welding and Riveting
Advantages of Welding
- Welding produces a stronger joint than riveting.

- Welding is less expensive than riveting.
Disadvantages of Riveting
- Riveting is slower than welding.
- Riveting is more difficult to perform than welding.
- Riveting is harder to automate than welding.
- Riveting is limited by the size of the hole in the part.
Advantages of Riveting
- Riveting has lower costs than welding.
- Riveting is easier to automate than welding.
Disadvantages of Riveting
- Riving is limited by the size and shape of the hole in the parts.
Conclusion
The two main types of joining techniques used in manufacturing are riveting and welding. In this video, we’ll discuss the pros and cons of each method and show you how to perform both processes.
Welding is a very versatile technique that can be used to join many different materials. Rivets are typically used to join metals together but can also be used to join other materials such as wood and plastic.
We hope this article will help you to choose the best method for your project.
