| Abstract Scope |
Numerical modeling of friction stir welding (FSW) is challenging because of the complex interaction between components. Quality model inputs are critical to model accuracy. Two key items are the heat generated due to friction at the tool/workpiece interface and heat transfer boundary conditions. Tuning of the model relies on adjusting friction and/or heat transfer coefficients to match experimental measurements. Prior studies tend to validate models using measurements from either the workpiece or the tool, but not both. Validating model predictions for both ensures that the heat generation levels are correct. The current work validates a FSW plunge model in both the tool and the workpiece. Various levels of heat transfer and friction coefficients were studied to achieve agreement with the experiment. Uncertainty in the thermocouple positions and machine compliance were accounted for. It was found that tool temperatures were more sensitive to the heat transfer coefficient than the workpiece temperatures. |
