What technological advancements have made riveting more efficient?

The advent of pneumatic tools made riveting more efficient. Today’s riveting process is done with special air-powered riveting guns that fire many times a second, hammering the rivet head into its final, mushroom shape. Pop rivets are also known as blind rivets because one person can easily install them.

Why riveting process is commonly used in aircraft assemblies?

Compared with welding mainly a fusion method, riveting a mechanical method generates no thermal deformation, hence widely used for joining high thermal conductive materials such as aluminum sheet metals used in aircraft assembly [1].

Which type of rivet is used in aircraft industry?

The universal head rivet and the 100 degree countersunk head rivet (MS20426) are the most widely used within our industry. See Figure 3. These MS numbers are also interchangeable with AN numbers AN470—MS20470 and AN426—MS20426. Additionally, two types of material are available within these designations.

What is the advantage of using flush rivets in aircraft construction?

A flush rivet takes advantage of a countersink hole; they are also commonly referred to as countersunk rivets. Countersunk or flush rivets are used extensively on the exterior of aircraft for aerodynamic reasons such as reduced drag and turbulence.

How does hot riveting work?

The hot upset riveting process uses heat and pressure to form a boss or rivet. At the start of the process, electrical current is applied to the workpiece. As the boss or rivet heats up, the material becomes malleable and collapses under pressure applied by the power head.

What is hot riveting used for?

Hot riveting is used mainly in the permanent mounting of materials, such as PCBs and covers to a building, and in permanently fastening lead frames.

Are bolts stronger than rivets?

For typical workshop applications, where pop rivets are usually used, threaded fasteners will provide superior strength. Pop rivets use a hollow shaft, reducing their ability to resist shear loads. By contrast, solid rivets are perhaps the strongest mechanical fastener available.

Is hot riveting still used?

Plastic and metal are two of the most common materials that have to be joined. Hot riveting is one of the most effective ways of joining materials. And it is being used extensively by many companies.

What is the process of riveting?

Riveting is a forging process that may be used to join parts together by way of a metal part called a rivet. The rivet acts to join the parts through adjacent surfaces. A straight metal piece is connected through the parts. Then both ends are formed over the connection, joining the parts securely.

What is the most common rivet?

Standard: The most common and the least expensive, these blind rivets are not watertight and aren’t as strong as other types of fasteners. Sealed: Similar to standard rivets, the mandrel on this rivet is completely enclosed, making it watertight.
