Friction Stir Welding of Dissimilar materials between AA6101 Aluminium and pure Copper
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2014, Vol 3, Issue 12
Abstract
There are many applications where dissimilar Aluminium and Copper weldments are used. In present work Friction Stir 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 at the surface of joint. Tensile testing of joint is done using computerized UTM.
