Review Paper on Friction Stir Welding of Aluminium and Magnesium Alloys

Objective: Friction Stir Welding (FSW) is a relatively new solid state welding technique for similar and dissimilar materials, especially on current interest with aluminum and magnesium alloys. Methods/Analysis: The Friction Stir Welding of aluminum alloys with magnesium alloys are reviewed on this paper. The basic principles of FSW are described, followed by process parameters study which affects the weld strength. Findings: The microstructure and the likelihood of defects also reviewed. Tensile strength properties attained with different process parameters are discussed. Conclusion/Application: It is demonstrated that FSW of aluminum and magnesium alloy is becoming an emerging technology with numerous commercial applications.
