In many ways, the Automotive industry is one of the most diverse and unique industries that MTI serves. Though the projects don't involve sending spacecraft into orbit like some of our Aerospace jobs, the demands of this ever-changing industry keep us on our toes and inspire us to keep thinking ahead.
MTI has gained global recognition for designing and building the most advanced, customized friction welding machines—including the world’s largest inertia friction welder.
While we are proud of building the largest rotary and linear friction welders in the world, we have also designed and built hundreds of smaller friction welding machines.
And that’s where the SPARTAN product line comes in, providing a high quality and cost-effective solution.
It's true - no two friction welding applications are the same. But no matter the part, the intent or the industry, there is one common goal we hope to achieve with each project we handle: create a component that is fit-for-purpose and can be ultimately joined on a production machine.
So, how do we accomplish this?
Using our friction welding and solid state joining know-how, MTI has developed, designed, and manufactured low force friction welding machines that are operating in industry today.
Solid-state welding processes are a group of technologies in which joining is accomplished without melting the individual substrates. In these processes, bonding is accomplished by a combination of heating and forging. Heating is used to both lower the flow stresses enabling forging, as well as promote diffusion between the individual substrates. Common variations of these processes include flash-butt, upset, projection, and mash-seam welding, as well as friction-based welding processes such as direct-drive, inertia, and linear friction welding.
For decades, MTI has successfully joined hundreds of applications across multiple industries using our traditional friction welding process. However, with the introduction of our newest solid-state joining technology, Low Force Friction Welding, you may now be wondering whether it's time to consider switching to Low Force - even if you've relied on our traditional process for years.
Long before the word "Tesla" spurred any thoughts beyond the iconic inventor of the 1800s, companies around the world were relying on friction welding to join their parts. But just as automotive technology has shifted throughout the decades, friction welding has followed right along, aligning with the demands of the modern consumer and commercial vehicle market.
When you think of friction welding, you likely imagine a highly engineered machine bringing two materials together and performing a solid-state weld using either a rotary, linear or stir motion.
It's a scenario you've likely encountered at least once.
You have two metals you want to join, but you're not sure which welding technology is the best fit for your application.
From Low Force Friction Welding to Friction Stir Welding, MTI specializes in several different types of friction welding processes. But in this article, we will explore our Inertia Rotary Friction Welding technology and explain how it works and outline how it could be beneficial in your next project.
MTI is proud to announce its involvement in a U.S. Department of Energy (DOE) research project, which focuses on the durability of friction welds created with dissimilar metals.
