Friction Welding

Friction Welding

Friction Welding and Its Advantages

Friction welding offers an efficient and sustainable method for joining metal components, ensuring high strength and reliability of the joints.

Friction Stir Welding

The principle of FSW technology

Friction stir welding (FSW) is a modification of the traditional friction welding and machining process.

It is a mechanical process whereby solid-state welding is performed using heat generated from the friction of a rotating tool. This process is invented and patented by The Welding Institute (TWI) in the United Kingdom in 1991. Designed for butt and lap welding of metals and plastics. Delivers defect-free joints with excellent mechanical properties.

Solid-state joining using rotational heat for clean, stable welds.
