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.

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.

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 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.

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.

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.

Friction Stir Welding is another friction welding technique that has beneficially impacted the aerospace, transportation and electronics industries. Like other friction welding processes, friction stir welding uses frictional heat and force to forge materials together creating extremely high-quality, solid-state joints.
