Enhancing Mechanical Properties of Friction Stir Welded Al Alloy Joints By Adding Magnesium Particles

Abstract

Friction stir welding (FSW), a solid-State welding technique, is being extensively used in similar as well as dissimilar joining of Al Mg, Cu, Ti, and their alloys. In the present study, the two aluminum plates are joined by adding Magnesium particles of 60 mesh were the welding zone before the welding was carried. The variable parameters that affect much are taken as input parameters. They are tool rotation speed, tool traverse speed and three different joint profiles like (straight, inclined, semicircle) and with and without magnesium the paper discuss the influence of hardness, tensile strength, impact strength. The work material conducted AA6061 T6. Taguchi method based on L18 so used as DOE.
