FSW (Figure 1) is based on the use of a tool consisting mainly of a probe, the height of which, inhe case of butt joints, is approximately equal to the thickness of the material to be joined, and a shoulder. For welding aluminium alloys, the tool is made of steel. Prior to being joined, the parts are brought together and fixed rigidly on a supporting plate, the process begins with perforation of the sheets by the rotating tool; once submerged in the material, the tool proceeds along the weld line. Little by little, the heat produced by the friction between the shoulder, the pin and the piece reduces the material’s resistance to plastic deformation. The rotation-translational motion of the tool allows the displacement of the material itself from the leading edge to the trailing edge. The metal is thus extruded and mixed. On cooling, the plasticised zone forms the weld between the edges. Also, by convention, the advancing side is the side of Micro friction stir welding of 2024-6082 aluminium alloys
