Rotary Friction Welding is a solid-state process in which one part is rotated at high speed and is pressed against another part that is held stationary. The resulting friction heats the parts, causing them to forge together.

PROCESS OVERVIEW

1.One piece is held stationary while the other piece is rotated.

2.Two pieces are then brought together as force is applied.

3.The force and rotating motion create friction at the faying surfaces, which is the interface of the parts being joined.

4.Friction creates heat. As a result, rubbing two faying surfaces heats the pieces and upsetting (bonding of parts) begins.

5.The rotary friction welding process is completed when the rotation of one piece stops and the upsetting ends. The result is a part with a 100-percent bond and a joint of forged quality.
