From American Friction Welding, Inc.

The challenges of material price versus performance in food manufacturing equipment have gotten tougher with each price increase for raw materials.
Friction welding as a way to reduce costs is a viable option for design engineering and new product development.

Although the term welding is used in defining the friction welding process, it bears no resemblance to conventional welding since no filler material is involved. Instead, two components are rubbed together at a controlled rotational speed, which creates the friction and heat that allows both components to reach a plastic state and forge together into a bond. Friction welding involves the use of unique technology incorporating state-of-the-art monitoring controls. This process is in widespread use by large OEMs throughout the industry.
