What is Orbital Friction Welding? Uses and Process

Orbital Friction Welding

Joining two pieces of metal together is no easy task, but orbital friction welding makes it look effortless. By combining solid-state heat generation with a spinning motion, this advanced process can securely and quickly weld two pieces of metal together. Let’s explore exactly how this process works and some of the key benefits that come along with it.

What is Orbital Friction Welding?

Orbital friction welding is a form of solid-state welding that uses heat generated from friction to create strong, reliable bonds between two pieces of metal. Unlike traditional arc welding techniques, which use gas or electricity to generate heat, orbital friction welding relies on spinning one piece of metal against another at high speeds to generate enough heat to fuse them together. This method creates a joint with very low levels of distortion and minimal material loss due to its relatively low-temperature range.

Orbital Friction Welding Uses

The unique properties of orbital friction welding make it an ideal choice for many different types of applications. Its ability to create joints with low levels of distortion makes it ideal for creating parts with complex geometries or tight tolerances, such as medical implants or aerospace components. It’s also used in the automotive industry for joining tubes and other components that need to have precise angles and angles. Additionally, since orbital friction welding produces fewer sparks than traditional arc methods, it’s often used in environments where combustible materials are present.


Orbital friction welding consists of three main steps; pre-alignment, spin-up/spin-down, and cool-down. During pre-alignment, the two pieces are clamped into place against each other, so they remain in contact during the entire process. In the spin-up/spin-down phase, the clamped pieces are spun rapidly against each other until enough heat has been generated from friction to weld them together. Finally, in the cool-down phase, the spindle is allowed to slow down gradually before being stopped completely after a certain period of time. This helps ensure that the joint will be strong and stable once cooled off completely.


Orbital Friction Welding is an advanced technique that combines heat generation from spinning motion to create strong bonds between two pieces of metal without relying on traditional arc or gas welding methods. It can be used for a variety of applications, including medical implants and automotive components, due to its ability to create joints with little distortion or material loss, even when working with delicate materials or tight tolerances. Although more expensive than other forms of welding, its precision, and reliability make it well worth considering when designing components requiring extremely durable bonds between metals!
