A Productive Friction Stir-Welded Aa 6061 Joints Using Different Pin Tool Profiles Configuration to Grow Mechanical and Microstructural Characteristics

Abstract

There are six brand-new dual-pin FSW tools that are displayed, each with a unique combination of Dual Circle, Dual Triangle, Dual rectangle, and Triangle-Rectangle profiles. Combination pins in the shapes of circles, triangles and rectangles were developed. The samples with the welded joints underwent quasi-static testing, and information on stress-strain was gathered. The use of dual pin welding equipment resulted in expanded SZ and improved plastic flow, among other micro-structural changes. The highest tensile strength and ductility were found in the weld connections made using Dual Triangle and Rectangle-Triangle tools. This investigation looks at the effects of tool shapes on the tensile characteristics and micro-structural components in the stir zone and heat-affected zone of friction stir-welded Al 6061 joints.
