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?

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.

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!

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.

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.

Throughout the past few episodes of Whiteboard Wednesdays, we've walked you through some of the key benefits of Low Force Friction Welding.

If you've been following along with our Whiteboard Wednesdays series, by now, you are likely beginning to understand some of the key benefits of Low Force Friction Welding.

In this episode, we will walk you through one of the biggest advantages of Low Force — the ability to accomplish little to no interior flash (ID.)

If you peel back the exterior of an airplane, you will find thousands of parts working together to help safely lift the plane into flight. And if you look a little closer, you'll notice some of those parts were joined by friction welding.

MTI has successfully friction-welded dozens of parts for aircraft and the aerospace industry. But perhaps no part is more complicated to take from concept to completion than the blisk.

  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 – Manufacturing Technology Inc., (MTI) announced it will develop North America’s largest Linear Friction Welder, in terms of force capacity and tooling envelope, and deliver it to LIFT – Lightweight Innovations for Tomorrow – for use in lightweight metals research and development projects, based in Detroit.

Friction welding is a forging technique that produces ultra-strong bonds for diverse applications. 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.

Two buzz words in the manufacturing industry today are near net shape manufacturing and additive manufacturing. Both terms are manufacturing processes that save time and money when producing parts.

Linear friction welding is similar to direct drive rotary friction welding since both are a constant energy input process. But unlike rotary, linear friction welding uses linear oscillation (a repeated back and forth motion) to create a solid state weld. There are two components of the oscillation that drives the energy input:

Linear friction welding is a solid-state joining process that uses relative motion and high force in order to create enough heat to create a two-piece forging. In linear friction welding, one part is moved back and forth rapidly in a linear reciprocating motion while the other part is forced into it, generating enough heat between the two parts to forge them together.

Manufacturing Technology, Inc., has shipped the world’s largest capacity linear friction welding machine, to Pratt & Whitney’s world-class Middletown facility in Connecticut. The machine will be used to friction-weld critical aircraft engine components to support Pratt & Whitney’s most advanced military programs and next generation product family.
