Short HistoryFriction Stir Welding was developed in England in the late 1980’s and patented in 1991. This means that in order to use the process, you must obtain permission.

So why bother? Because it has some unique advantages that no other welding process, right now, have.

Page 10: Welding Friction Stir Welding (FSW) Copyright © Texas Education Agency, 2012. All rights reserved

The ProcessRotating tool

Central pin/probe

Heats

Plasticizes

Moves tool along the joint

Movement pushes material to the rear, eliminating interface.

UsesOriginal applications for FSW include:

Welding of long lengths of material in the aerospace,

Shipbuilding

Railway industries.

Formula 1 race cars

Other examples include large fuel tanks and other containers for space launch vehicles, cargo decks for high-speed ferries, and roofs for railway carriages.
