The process of Friction Welding has been utilized in the United States and Europe for over 50 years. Although well known to some, in general it has been a very well kept secret. Once people completely understand the process, its benefits quickly become evident.

Friction welding is a "solid-state joint process that produces coalescence of materials under compressive force contact of workpieces rotating or moving relative to one another to produce heat and plastically displace material from the faying surfaces". The friction welding machine controls this rubbing through a series of unique parameters for rotational speed (rpm’s), axial force, and time. Once these parameters are established, they are recorded, stored, and then repeated with each cycle of the machine.
