Investigation of Optimal Temperature Distribution, Mechanical Properties and Microstructures of Friction Stir Welded Copper Alloy Joints

Abstract

In this work to determine the maximum temperature at weld zone by using three dimensional finite element heat transfer model is developed by ANSYS. Copper specimens were prepared under different FSW condition, by varying the tool speed, welding speed and axial force in a vertical axis CNC milling machine by programming (APT). Plans of experiments were via 8 experimental runs are based on the Taguchi orthogonal arrays to determine the optimum factor level condition and also carried out the experimental mechanical tests on the copper joints to characterize the mechanical properties like tensile strength, percentage of elongation, hardness and microstructures.
