WebLarge-scale Circumferential Friction Stir Welding Machine. Highlights ★ Welding depth up to 16 mm (2XXX) ★ Diameter up to 3,350 mm ★ Length of product up to 12,000 mm … Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material. Heat is generated by friction between the rotating tool and the workpiece material, which leads to a softened region near the FSW tool. … See more The FSW is performed with a rotating cylindrical tool which has profiled pin (also known a probe) having diameter smaller than the diameter of shoulder. During welding the tool is fed into a butt joint between two … See more The solid-state nature of FSW leads to several advantages over fusion welding methods, as problems associated with cooling from the liquid phase are avoided. Issues such as See more During welding, a number of forces will act on the tool: • A downwards force is necessary to maintain the position of the tool at or below the material … See more For any welding process, it is, in general, desirable to increase the travel speed and minimise the heat input, as this will increase … See more The solid-state nature of the FSW process, combined with its unusual tool shape and asymmetric speed profile, results in a highly … See more Tool design The design of the tool is a critical factor, as a good tool can improve both the quality of the weld and the maximal possible welding speed. See more Early work on the mode of material flow around the tool used inserts of a different alloy, which had a different contrast to the normal material when viewed through a microscope, in an effort to determine where material was moved as the tool passed. The data … See more WebFeb 20, 2012 · Method of Circumferential Friction Stir Welding without Using an Internal Mandrel.
