What Is Friction Welding And How Does It Work?!?

Friction welding has been used to weld parts to make new or repair for many decades. The friction welding family of processes offers many different variants, including linear friction welding, rotary friction welding and friction stir welding. Though all of these processes differ in one way, they all have one purpose and work similarly.

In each case, friction heats the given materials in conjuction with an applied force so to create the necessary weld. All of these processes are classified as solid-state welding because no melting occurs whatsoever.

Frictin drilling, furthermore, often profuces welds with mechanical properties and the resulting weldment hasn less distortion than what fusion welding methods offer.
