What are the main applications of FSW in aeronautics industry?

Friction stir welding (FSW) is a welding technique that has been democratized in the aeronautical sector.
The FSW offers the ability to weld large or complex panels such as wedi hull plates. It also provides a robust and reliable alternative to riveting.
In addition, FSW offers new perspectives for the manufacture of more environmentally friendly aircraft. This innovative technology allows for a reduction in machining scrap. The aeronautical industry is studying the design of cryogenic hydrogen tanks based on FSW.
