Friction Stir WeldingBiSS friction stir welding test rigs feature high-stiffness; precision-aligned annular load frame with 5 axis movements and independently controlled servo-actuators using the advanced features of the 2370MS controller to provide translation and deformation control of each axis, these systems are ideal for welding aluminium sheets. In FSW, a cylindrical shouldered tool with a profiled pin is rotated and plunged into the joint area between two pieces of sheet or plate material. The parts have to be securely clamped to prevent the joint faces from being forced apart. Frictional heat between the wear resistant welding tool and the workpieces causes the latter to soften without reaching melting point, allowing the tool to traverse along the weld line. The plasticised material, transferred to the trailing edge of the tool pin, is forged through intimate contact with the tool shoulder and pin profile. On cooling, a solid phase bond is created between the workpieces. |
