Friction Stir Welding (FSW) is a solid-state joining process widely used for welding metals, especially aluminum and its alloys. Invented in 1991 by The Welding Institute (TWI), FSW uses a non-consumable rotating tool with a specially designed pin and shoulder to generate frictional heat, softening the materials at the joint without melting them. The rotating tool stirs and forges the softened material together, resulting in a high-strength, defect-free weld. FSW is energy-efficient and ideal for aerospace, automotive, and marine applications due to its ability to join dissimilar materials and produce superior mechanical properties compared to conventional welding methods.
Friction Stir Welding (FSW) has gained significant industrial adoption due to its advantages in producing high-strength, defect-free joints in lightweight materials like aluminum, magnesium, and copper alloys. Its applications span across aerospace, automotive, shipbuilding, and rail industries, especially for structures requiring precision and strength. FSW allows welding of dissimilar metals and complex geometries with minimal distortion. Research continues to expand its applicability to harder materials like steels and titanium. Automated FSW systems and robotic integration are also advancing, making the process more versatile for mass production. Its environmental benefits, like low energy consumption and absence of harmful emissions, further enhance its appeal.
