Computational models have been of great use to understand various aspects of welding processes and can be useful to understand tool wear during friction stir welding (FSW) of high strength materials. However, computational models are not available for estimation of tool wear and pin shape during FSW of high strength materials. A three dimensional heat transfer and material flow based model is developed to estimate tool wear and worn out tool pin shape during FSW of CuCrZr alloy. Mass, momentum and energy conservation equations are solved to compute temperature evolution and material flow. The computed temperatures are used to calculate forces and stresses acting on the tool. The estimated tool pin shape from the model are compared with experimentally observed shape for various combinations of process parameters. The developed wear model can be used to understand and estimate worn out tool shape during FSW of several other high strength materials.
