What is Friction Welding ?

Friction welding is a method for making welds in which one component is rotated relative to, and in pressure contact, with the mating component to produce heat at the faying surfaces. The weld is completed by the application of a forge force during or after the cessation of relative motion.

Friction Welding Process

Friction welding is a completely mechanical solid-phase process in which heat generated by friction is used to create the ideal conditions for a high integrity welded joint between similar or dissimilar metals. In its simplest form, friction welding involves holding two components in axial alignment. Then rotate them under pressure causing the interface to heat up.
