Friction Stir Welding (FSW) is a solid-state joining process that’s especially popular in the aerospace, transportation, and electronics industries.

Below, we'll explore some commonly asked questions about Friction Stir Welding.

In our fourth installment of Eyes of an Engineer, we introduce you to junior service engineer James Lovell and junior design engineer Luke Barratt.  Luke and James both graduated from MTI’s apprenticeship program in February of 2018.

Discover why they chose MTI, what they learned, and where they’re headed next.

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:

Global joining solutions provider MTI has collaborated with technology company HMK, the Siemens motion partner, to pioneer the development of a double axle friction welding machine worth in excess of $2.4 million for one of the world’s leading trailer manufacturers.

In our third installment of Eyes of an Engineer, we introduce you to Tori Zellerhoff and Margot Hughan.  They began working at MTI as part of their capstone thesis for Notre Dame’s Master’s Program in Entrepreneurship, Technology, & Innovation (ESTEEM).

Combining technology with entrepreneurship, the two developed a business plan and go-to-market strategy for MTI’s latest technology, low force friction welding. 

Find out how they got started, what they learned at MTI, and what they enjoyed most about the experience.

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.

South Bend, IN - October 6, 2017:  Manufacturing Technology, Inc (MTI) opened its doors to area high schoolers in celebration of Manufacturing Day. The nation-wide event introduces the next generation of workers to high-skilled careers in modern manufacturing.

Students from Riley, Washington, and Adams High School attended the event, which was held at MTI’s world headquarters. 

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. 

Here are the three things you need to know about MTI’s latest double axle machine:

SOUTH BEND, IN - Aerojet Rocketdyne, a subsidiary of Aerojet Rocketdyne Holdings, Inc. (NYSE: AJRD), has recognized Manufacturing Technology, Inc. (MTI) for its work on the RS-25 rocket engine, a key element of NASA’s space exploration program.  MTI was instrumental in the refurbishment of the inertia welder and production inertia welding for the RS-25 Main Injector. 

 When it comes to friction welding, we want to work towards repeatability, even when there are incoming part variations.  But how can we do that?  One way is through pressure modulation.

When a 261 metric ton airplane lands or a medivac helicopter is headed to the hospital—that is no time for a critical component to fail.

MTI understands this. That’s why we’re NADCAP* accredited. Our aerospace partners like GE, Pratt & Whitney, Rolls-Royce, Boeing, and Honeywell trust the quality of MTI’s welded parts.  

SOUTH BEND, IN - Ball Aerospace has recognized Manufacturing Technology, Inc. (MTI) for outstanding technical performance on the TIRS-02 Program, a NASA initiative which uses thermal infrared sensors to measure the Earth’s temperature.  MTI played an integral role by joining together titanium and copper for the TIRS-02 Cryocooler, which is used on the Landsat Data Continuity satellite.

“We were thrilled to work with Ball Aerospace and work together to find a joining solution that met their needs” said Mike Laiman, MTI’s Manufacturing Services Business Unit Manager.  “Collaboration was key to our success.”

SOUTH BEND, IN - Manufacturing Technology, Inc. (MTI) today announced changes to the company’s leadership team, as well as the addition of three outside Board of Director members.  The changes are part of the company’s focus on new product development, operations, and sales.

Dan Adams, who is currently MTI’s President and one of the company’s fourth generation owners, is assuming the role of CEO.  He will continue overseeing the company’s recently launched new product development efforts.
