FSW works by using a non-consumable tool, rotated at the interface of two workpieces, in our case aluminium. The tool is then moved through the interface and the frictional heat causes the material to heat and soften. The rotating tool then mechanically mixes the softened material to produce a solid-state bond.

Advantages of FSW

·       A high welding speed

·       No filler material

·       Superior mechanical properties: weld with improved strength, resistance, sealing and durability

·       Less distortions, and therefore better controlled final dimensions

·       Final weight assembly reduced

·       An aesthetic weld

·       An increased lifespan of the products concerned

·       A process suitable for dissimilar materials

·       Greener production – no harmful gaseous emissions, no grinding residues,

·       A safer workplace
