Friction Stir Welding (FSW) is widely used in the aerospace sector due to its high-quality welds, low deformation, and suitability for lightweight materials. It is used in fuselage structures such as fuselage panels, skins, and frames, reducing the use of rivets, lowering weight, and enhancing structural strength and fatigue performance. It is particularly suitable for manufacturing liquid fuel tanks, ensuring sealing, reducing leakage risks, and improving safety. For engine mounts and casings, FSW performs excellently with high-temperature alloys, adapting well to the high-temperature and high-pressure environments of engines.
