LINEAR FRICTION WELDING

MTI Welding Technologies is based in the heart of the midlands and is part of the larger MTI group of companies which was founded in 1926. Over time, MTI has expanded and established operations in several countries, including the UK.

In the world of Aerospace and advanced engineering, titanium forgings have long been hailed as critical, unique materials for their lightweight yet high strength properties. However, a recent and developing disruption to the existing supply chain may threaten the availability of these critical components.

Amidst this challenging scenario, a promising solution emerges – Linear friction welding, a cutting-edge technique that has the potential to mitigate the crisis and revolutionize the manufacturing of titanium forgings.

The Challenge

As a critical and highly demanded material, supply chain issues cause disruptions for the companies that depend on it. Given the sometimes complex geometry and critical nature of the components manufactured from the forgings, the tooling and machines required to provide an alternative solution to component supply are not easily replaced. That brings us to the current challenge. Russia is a top supplier in the titanium market, accounting for nearly 20% of the global supply and 45% of titanium Aerospace components.

With international sanctions being imposed against Russia (and predicted to increase), it's essential to consider alternative ways of manufacturing titanium forgings that are cost effective and environmentally conscious.

Titanium Forgings

So, why are titanium forgings so unique?

Titanium forgings refers to Titanium that has undergone a forging process where the metal is hot forged into the required geometry according to the desired application. By undergoing a forging process, the titanium gets enhanced strength, improved material integrity, and a longer useful life with minimal maintenance needed because the grain direction is manipulated in accordance to the load path within the component during its service life. Besides enhanced strength, titanium is also forged because the price per pound of raw titanium is high, and forgings are designed to minimize the amount of expensive material that needs to be r
