Effect of Friction Stir Welding Parameters on the Mechanical & Microstructure Properties of Aluminium 6061 Alloys

Abstract

Objective: Friction stir welding (FSW) is a relatively new solid state welding technique for similar and dissimilar materials, especially on current interest with Aluminium 6061 to Aluminim 6061. Method/Analysis: The present paper discusses the process parameters followed by mechanical properties and microstructures which affect the weld strength. Findings: Mechanical properties-Tensile strength attained with different process parameters and Microstructures are obtained by Optical Metallurgical Microscopy (MET SCOPE-1) and a Scanning Electron Microscopy equipped with an X-radiation detector EDS Conclusion/Application: In this study Similar FSW between Al 6061 to Al 6061 plates with thickness 6mm were performed. The future research will contain creep tests and microstructural investigations using aluminium 6061 alloy using TEM microscopy (Transmission Electron Microscopy).It is demonstrated that FSW of aluminium to aluminium alloys is becoming an emerging technology with numerous commercial applications.
