Effect of Tool Pin Diameter on the Tensile Strength of Friction Stir Welded AA6061 Joints: Implications for Railway Carbodies
Friction stir welding (FSW) is a solid-state joining process that is increasingly used to fabricate aluminum railway carbodies. This study examined the effect of tool pin diameter on the tensile properties of FSW joints in 6 mm thick AA6061-T6 aluminum plates. High-speed steel tools with a 13 mm flat shoulder and strai...
