Description
A phenomenologically based semiphysical modelling approach was employed to develop a process window for friction stir welding (FSW) of AA 2024-T3 aluminium alloy, incorporating simulation of the filling level of the welded joint as a means to determine its soundness. The model was based on the mass conservation law and EMSO (environment for modelling, simulation and optimisation) software was used for simulation. FSW experiments were conducted on AA 2024-T3 sheets (thickness 4.8 mm) with an adapted milling machine in position control mode and an H13 steel tool at a rotational speed of 500-1085 rpm and a traverse speed of 45-187 mm/min. Voids or material flaws were measured using a micropipette and displaced volume data were transformed into a filling level. Process parameter combinations were simulated with EMSO software.
