A quasisteady approach to friction stir welding (FSW) heat transfer modeling is proposed and implemented using FLUENT. An idealized model of the mechanical dissipation heating in FSW is employed. Selected numerical predictions based on the model are shown to capture most of the features of corresponding experimental data available in literature. It is concluded that the quasisteady formulation (due to its simplicity and moderate usage of computational resources) is an attractive alternative to more computationally intensive unsteady approaches to FSW modeling under some circumstances.
