A Simplified Design of Clamping System and Fixtures for Friction Stir Welding of Aluminium Alloys

Sound friction stir welds could be attained by using an active design of backing/clamping system with a proper selection of the welding parameters. This work presented a simplified design of fixtures and backing plates to be used for friction stir welding of aluminum alloys. The test-rig was const...
