Performance Evaluation of Friction Stir Welding of Dissimilar Materials

Abstract

The friction Stir Welding is a process concerning plastic deformation of the materials to be joined.This process does not involve the melting of the materials to be joined. This thing makes thisprocess suitable for joining the different materials having different mechanical and chemicalproperties and different material structure.In contemporary work FrictionStir Welding of AA6101 Aluminium and pure Copper plates of 5mm thickness in butt joint configuration is done.Friction stir welding is done at 700 rpm and at 11mm/min tool traverse speed with cylindrical H13 material tool.For this vertical machining center is used. Joint shows onion ring structure in stir zone. Cavity like defect are seen atthe surface of joint.
