Friction Stir Welding Test Rigs

Bangalore Integrated System Solutions Private Limited offers BiSS Friction Stir Welding (FSW) Test Rigs. These 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. The 2370MS controllers require a separate host computer and a PC running MS-Windows. All operations including system set up, calibration and tuning are performed from this computer. BiSS hardware is designed to deliver high-speed closed loop control and data acquisition. A unique feature of the 2370MS controller is the GDS environment. The GDS environment effectively converts the control system into an application server, permitting the connection of additional networked MS-Windows terminals, each with its own keyboard and mouse and Windows desktop.
