What are the main applications of FSW in aerospace industry?

Friction stir welding has many applications in the aerospace industry. Indeed, this sector has adopted FSW, which makes it possible to weld all aluminum alloys
One of the main aerospace applications is the assembly of aluminum hydrogen tanks. FSW provides a higher strength weld than conventional welding processes such as TIG or arc welding.
The development of aluminium liquid cold plates in the aerospace industry was also made possible by friction stir welding.
Aluminum parts previously assembled by riveting, such as aircraft sides or floors, can be welded with FSW while maintaining the mechanical properties of the metal.
