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.

There's a reason you clicked on this blog.

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.

Friction welding offers a world of possibility for all types of industries, and MTI is a global leader in this highly adaptable technology. Our engineers are continually innovating and creating new solutions to difficult manufacturing challenges.

One place friction welding technology is making a difference, is in the oil and gas industry. With durable welds that can stand up to incredible stress, friction welding is a practical response to the demands that are put on drill pipes, manifold tubes, valves, perf-gun tubes, actuation balls, and more.

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.

Adding to its continually growing list of value-added offerings, MTI UK's contract friction welding facility has welcomed a new, state-of-the art CNC machine onto its shop floor.

From Low Force Friction Welding to Friction Stir Welding, MTI specializes in several different types of friction welding processes.

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.

Practice makes perfect: it’s an old saying, but one that continues to ring true in just about every aspect of life – especially when it comes to manufacturing.

Total indicator runout, or TIR, is a term often used in manufacturing, especially when dealing with rotating parts.  Other names include total indicator reading, or more recently, full indicator movement (FIM).  TIR is simply the difference between the maximum and minimum values measured across an entire rotating surface about a reference axis.

Following a nearly seven-week closure of our buildings amid the COVID-19 pandemic, MTI reopened its doors on May 11 to resume US operations after Indiana's governor deemed it was safe for non-essential manufacturers to do so.

The world of friction welding is vast -- and so is the vocabulary used to describe it! We've compiled a list of the most commonly used friction welding terms -- from machine components to MTI's processes -- to help you grow your engineering mind!

It's our newest technology and has the potential to revolutionize solid-state joining as we know it - Low Force Friction Welding is here to stay and since its inception, we've learned a lot about its potential in all of the industries that MTI serves.

You might not realize it yet, but friction welded parts are all around us, from the cars you drive to the planes you fly in.

Here’s a look at some everyday objects you never knew were friction welded:

Friction welding is rooted in a fairly simple, yet effective concept: make good parts great and strong parts even stronger.

The future of integration is now. What do I mean by that? I mean, we have seen many examples of how friction welding is seamlessly integrated into an automated manufacturing process. A number of our customers are already working with us and integrating friction welding technology into their production process. Based on their successes, it is the right time to take advantage of this innovative process that leads to (1) process repeatability, (2) improved cycle time, (3) increased production volume, and (4) cost savings.

The whir of machines, the beep of a forklift— a manufacturing floor isn't exactly a place you'd go to find some peace and quiet. But nestled among the hustle and bustle of MTI's Manufacturing Services building, you'll find a much quieter place; one that fosters thorough analyses and a methodical evaluation process that's one part science, one part art.

2020. We made it.

The confetti has fallen, the noisemakers have been tucked back into storage, and now, we're left with an unfiltered view of both a new year and a new decade (unless you're one of those people who believes the new decade doesn't begin until 2021, but that's a separate discussion.)

Though MTI is eager to dive head-first into 2020, we first want to pause and reflect on our accomplishments from 2019 – after all, without them, we wouldn't be where we are now!

Developing and engineering a part for the aerospace industry is no easy task — but then again, why should it be? Companies depend on these parts to help keep passengers and cargo safe each time a plane takes off, lands and every step in between.

Friction welding is not a one-size-fits-all process — that's what makes it such a versatile joining method.  It's just as effective for joining components that you can fit in the palm of your hand as it is for joining parts that require a crane to move from one place to another.

At MTI, there’s a reason why we use the word “family” so often – it’s at the core of who we are as an organization.

Friction Welding has become the premier choice for companies looking to join dissimilar metals.  Because Friction Welding is a solid-state joining process that does not require melting, it allows for the bonding of two metals, such as Copper and Aluminum, that may be impossible to join with more traditional welding techniques.

With fusion welding processes like MIG and TIG welding, it can be challenging to join dissimilar metals because they often differ substantially in composition and physical, mechanical and metallurgical properties.

At MTI’s Manufacturing Services, we do more than bond parts together; we provide you with a proven, turnkey solution. Whether you need help with just one portion of the friction welding process or want guidance every step of the way, MTI’s team of highly skilled engineers is ready to help.
