Friction Stir Welding

Friction stir welding

Friction stir welding (FSW) is a solid-state joining process used to join two similar and dissimilar materials below the liquidus temperature of the material. It is a recently developed technique by The Welding Institute (TWI) in 1991. The advantages of FSW over conventional welding techniques had led to its advancements in almost all the industrial sectors. The increasing demand for the high strength to weight ratio components has led to various materials in industries such as polymers, ceramics, metals, composites, etc.
