Effects of Welding Parameters On Mechanical Properties of Aa7050 Fsw Joints
<p> Friction Stir Welding (FSW) is a solid state joining process invented in 1991 by The Welding Institute (TWI, Cambridge, UK). The performance of the resultant welded joint in high strength aluminum alloys sets FSW apart from traditional fusion welding. Rapid process development of FSW joints for …
