“…Different welding parameters can lead to a different combination of strain and temperature distribution in the NZ. Normally, heat is generated by friction between the tool and work piece and via plastic deformation during FSW [4,36,37]. The volumetric heat sources Φ represents the plastic deformation inside the shear layer of the work piece:…”

“…Recently, Su et al [11] modelled the effects of tool geometry on the thermal and plastic flow behaviour during FSW of AA2024 using the CFD code FLUENT. The study investigated both conical and triflat tool designs and used experimental weld data to calculate the friction coefficient and slip rate on the tool surface.…”

The tool is a key component in the friction stir welding (FSW) process, but the tool degrades and changes shape during use, however, only a limited number of experimental studies have been undertaken in order to understand the effect that worn tool geometry has on the material flow and resultant weld quality. In this study, a validated model of the FSW process is generated using the CFD software FLUENT, with this model then being used to assess the detail of the differences in the flow behaviour, mechanically affected zone (MAZ) size and strain rate distribution around the tool for both unworn and worn tool geometries. Comparisons are made at two different tool rotational speeds using a single weld traverse speed. The study shows that there are significant differences in the flow behaviour around and under the tool when the tool is worn. This modelling approach can therefore be used to improve understanding of the effective limits of tool life for welding, with a specific outcome of being able to predict and interpret the behaviour when using specific weld parameters and component geometry without the need for experimental trials.

“…This is because thorough understanding of the flow will help to predict the performance of friction stir welds in service. Researchers have employed different techniques and models in attempting to establish the flow patterns, as well as material positioning in dissimilar friction stir welds with consideration of different welding parameters [1][2][3][4][5][6][7][8][9][10][11][12][13]. However, all of these are far from being fully understood and established.…”
