Development of Thermo Mechanical Model for Prediction of Temperature Diffusion in Different FSW Tool Pin Geometries During Joining of AZ80A Mg Alloys

Heat generated during the friction stir welding (FSW) process is of complex nature and plays a vital role in influencing quality fabricated joints. In this experimental research, an thermo mechanical model was formulated to estimate values peak temperatures employment FSW tools with four different pin geometries (namely cylindrical, taper square triangle) for joining AZ80A Mg alloy flat plates, understand their significant size grains, strength The temperature are found be consistent that actual results exhibited relatively very small variation It observed joints by cylindrical geometry possess fine sized due generation ideal (i.e., 348 °C which nearly 81–82% melting Workpiece).
