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.

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.
