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 no secret Friction Welding is a highly scientific process; it involves a lot of calculations, engineering and research to get it right. But thanks to the MTI-engineered control system found on each of our friction welding machines, you can trust our technology to do the complex work for you on your shop floor!

DETROIT – The first and only linear friction welder capable of full-sized part development in North America is now fully operational and ready for project work at LIFT - Lightweight Innovations for Tomorrow, a national manufacturing innovation facility operated by the American Lightweight Materials Innovation Institute, in Detroit.

Steel and Inconel: they look similar, but metallurgically speaking, they’re two very different materials. They melt at different temperatures, they have different densities and their forgeabilities vary greatly.

Kingswinford, UK – MTI Welding Technologies, Ltd. is building a state-of-the-art friction welding machine for a leading truck manufacturer in Europe.

South Bend, Ind. - Recently recognized for its role in high-profile space missions, Manufacturing Technology, Inc. (MTI) is gearing up to showcase its friction welding expertise to some of the biggest aerospace influencers in the nation.

The year was 1970: the Boeing 747 had just completed its first commercial flight, IBM was preparing to shake up the tech world with the floppy disk and Americans were flooding the streets, calling for stricter environmental regulations.

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.

WELDING PROBLEMS THE RAIL INDUSTRY FACES TODAY

For decades, railroad companies have been welding 80-foot rails to form Continuous Welded Rails (CWRs) that span from 400 feet to several miles. To accomplish this, they’ve heavily relied on two forms of welding: thermite and flash-butt. However, despite the wide use of these two processes, a significant percentage of railroad failures are a result of low-quality welds.

Friction welding is a solid state joining process. It’s actually a forging process: not a welding process. In the Friction Welding process we use relative motion and high force in order to create frictional heat at the weld interface. This heats the materials being joined to the point where they will plasticize without melting. The result is molecular intermixing at the weld interface and a forged quality joint.

  SOUTH BEND, IN - OCTOBER 9, 2018: Manufacturing Technology, Inc. (MTI) has shipped North America’s first linear friction welder capable of full sized part development to the LIFT - Lightweight Innovations for Tomorrow facility in Detroit where it will contribute to cutting edge lightweighting research in the automotive and aerospace sectors.

SOUTH BEND, IN -- Former astronaut Brian Duffy along with representatives from NASA, Aerojet Rocketdyne, Boeing, Lockheed Martin and Orbital ATK acknowledged Manufacturing Technology, Inc (MTI) for its contributions to the NASA Space Launch System (SLS).

In friction welding, we always strive toward repeatability—even when there are differences in the length of incoming parts.  This is especially true in the automotive and aerospace industry where finished parts are held to rigid standards.  Using Torque Modulation with Dynamic Profile Modification, we’re able to ensure our first welded part is the same length as our last welded part. 

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.

Unscheduled downtimes can result in significant financial losses and consume the maintenance department. That’s why refurbishing your old friction welding machine has several cost-saving advantages. 

If you’re falling behind or having difficulty meeting quality compliance, an MTI upgrade may be just what you need. 

Here are 5 signs to look for:  

Our customers—especially those in the automotive industry—rely on repeatable upset in order to meet tight part tolerances.  Remember, upset is the amount of shortening of the two parts as a result of friction welding.

Leveraging the latest in advanced rotary friction welding technology, MTI’s newest double axle machine increases efficiency, accuracy, and cost-effectiveness in axle production.

This process has been the answer to many manufacturing and engineering challenges for over five decades. From aerospace to automotive, friction welding is continually opening the possibilities for ongoing technological advancement.

Thanksgiving is finally here! It’s time for succulent turkey, tart cranberries, savory stuffing, and the ultimate side dish: creamy mashed potatoes.

Friction welding offers a wealth of solutions to tough manufacturing problems. Thanks to key advantages — such as consistent quality, the ability to join different metals together, and reduced material waste — friction welding is a time-efficient and cost-effective way to produce new parts. Friction welding is a powerful process that not only provides forged quality components, but gives engineers the confidence that the part will meet the quality standards of their application.

SOUTH BEND, IN-  As part of an ongoing strategy of investing in and adapting to the best market opportunities, Manufacturing Technology, Inc. (MTI) is proactively realigning its US machine build and corporate operations.  This allows the company to be more cost competitive, and will result in 24 positions being eliminated or reassigned. MTI’s UK operation is not affected.

MTI’s US business is built around large complex friction welding machines, a successful niche, but only a small portion of the global market.  The global friction welding machine market is dominated by smaller automated machines.  This is a segment where the US operation has become much less cost competitive over time.

Over the course of this series on upset control, we’ve discussed the repeatability of upset control and part variation in rotary friction welding. Remember, upset is the amount of shortening you get in the part as a result of friction welding.  Upset is different than overall length, which is the total length of the part after welding.

When manufacturing critical components for applications such as transportation, space flight, oil & gas, construction, and the military, quality isn’t just important — it’s absolutely essential. Implementing a trusted joining technology allows components to reach the desired quality and durability.

The International Manufacturing Technology Show (IMTS) is held every two years in Chicago giving national and international manufacturing companies an opportunity to network, learn about new technologies and engage with colleagues. This year’s IMTS wrapped up on September 17, 2016 and once again MTI was thrilled to have spent the week meeting new people, hearing about new challenges and teaching people about friction welding.

In Part One of this series, we talked about how upset is the amount of shortening of a part resulting from friction welding. Remember, if we had perfect incoming parts then we could fix the amount of energy used to make that weld, and get very repeatable upset. However, incoming parts variations such as area differences, surface conditions, material differences, or even interface “squareness” can cause subtle variations in upset.
