Title

EFFECT OF DIFFERENT BACKING PLATE ON THERMO-MECHANICAL MODELLING OF FRICTION STIR WELDING IN ALUMINIUM ALLOY AA 2014

Abstract

This research aims to experimentally explore the thermal histories and temperature distributions in a workpiece during a friction stir welding (FSW) process involving the butt joining of aluminum AA 2014 T6. K- Type thermocouples are used to measure the temperature histories during FSW at different locations on the workpiece in the welding direction. Successful welding processes are achieved by appropriately controlling the maximum temperatures during the welding process. Regression analyses by the least squares method are used to predict the temperatures at the joint line. A second-order polynomial curve is found to best fit the experimental temperature values in the thickness direction of the workpiece. A three-dimensional thermal model for Friction Stir Welding (FSW) is presented. Series of welds were made by friction stir welding (FSW) with various backplates made out of materials ranging from low diffusivity Asbestos to high diffusivity copper in order to reveal the effect of back plate diffusivity on the joint microstructure and properties. The peak temperatures and cooling rates can be used to explain the microstructure evolution during cooling in different regions of the weld. The results of the simulation are in good agreement with that of experimental results.
