Friction stir welding, Tool profile, Simulation, Static & Dynamic AnalysisAbstract
In case of Friction stir welding (FSW) process, a spinning non- consumable tool is used to generate frictional heat in the work piece due to which joining occurs without melting of metal therefore friction stir welding is categorized as solid state joining process. A lot of experiments and research has been carried out in this technique for joining of similar and dissimilar aluminum alloys. Welding of steel and other similar metal is still a challenge for scholars and researchers. A part from experimental work related to study of friction stir welding, there is space to work on modeling & simulation of friction stir welding tool and process by using analysis software like ANSYS, Hyper Works, etc. The simulation work includes static and dynamic analysis. Through this article some light is put on the above aspects through the available literature. Static analysis of FSW is performed on different types of tool profiles which are modeled and analyzed in ANSYS for the condition of structural and thermal loadings. Dynamic analysis of FSW is performed on tool & work piece for obtaining residual stresses and temperature gradients along the weld line of the plates. In this case the pin of tool is neglected because of negligible heat generated through pin and the focus is only on the shoulder.
