Description
The development and experimental validation of a finite element model ("DEFORM-3D" software) for friction stir welding (FSW) of 7XXX series aluminium alloys (e.g. AA-7075) with varying pin angle and advancing speed are described, and application of the model to predict process variables and to highlight issues in FSW of tailored welded blanks is reported. The model is thermo-mechanically coupled, uses a rigid-viscoplastic material description and a continuum assumption for the weld seam, and is capable of forecasting such characteristics as temperature, strain and strain rate as well as material flow, forces and grain size in the welded joints. Results obtained showing the effect of pin angle on the main process variables and the consequences for HAZ, TMAZ (thermomechanically affected zone) and nugget are discussed.
