Prediction of the temperature recorded in lap joint at during the friction stir welding

The aim of the present work is to model the parameters influencing the temperature during friction stir welding. The area of physical understanding is the influence of tool pin geometry and material on the temperature field, microstructural refinement, resulting material flow and the influence of flow variations on the subsequent mechanical properties of FSW lap welded joints in aluminium 3003. The results obtained allowed us to propose a mathematical model to study the interactions between the different factors. It was found that the most influential parameters are the rotation speed and the welding speed.
