  • Friction stir welding and processing - ScienceDirect

    2005-8-31 · Friction stir welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used to join high-strength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding.

    2018-1-30 · Based on these observations, Reynolds et al. [29,30] suggested that the friction stir welding process can be roughly described as an in situ extrusion process wherein the tool shoulder, the pin, the weld backing plate, and cold base metal outside the weld zone form an extrusion chamber which moves relative to the workpiece.
