The difference between riveting and welding

Riveting and welding are two common methods of metal joining, and they have some differences:

How it works:

Welding is the process of creating a molten state on a metal surface and then fusing two or more metal parts with each other to form a permanent connection.

Riveting is the process of placing a rivet or cap (one end of a rivet) between two or more parts, and then using a rivet gun or other tool to press the rivet to form a permanent connection.

Connection:

Welding is the formation of a continuous connection between metals, so that two metal parts are fused into a single whole in the welded area.

Riveting joins the metal by passing the rivet or rivet cap through the metal part and forming a head at the other end, which makes it impossible to remove the rivet from the metal part.

Applications:

Welding is often used in applications that require high strength and tightness, such as automotive manufacturing, shipbuilding, and pipe connections.

Riveting is commonly found in applications that require frequent disassembly and reconnection, such as the connection of aircraft, machinery and equipment, and some building structures.

Connection Quality:

Welding is usually able to provide higher joint strength because the metal is continuous during the welding process and there are no gaps.

Riveted joints typically have slightly lower strength than welding, but may be more suitable in some cases as it can provide a more flexible connection.

Operational Complexity:

Welding usually requires a high level of skill and expertise, as the welding process involves controlling parameters such as high temperatures, currents, etc.

Riveting is comparatively less technically demanding as it does not involve the melting of the metal and only requires proper tools and techniques to complete.

Overall, welding provides a stronger connection and is suitable for applications that require high strength and tightness, while riveting provides a more flexible connection for applications that require frequent disassembly and reconnection.
