Abstract
The objective of the present work is the modelling of parameters influencing the temperature during friction stir lap welding. The area of physical understanding is the influence of the 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 butt lap joints in aluminium 3003 Alloy. The results obtained allowed us to propose a mathematical model to study the interactions between different factors. Thus, it was shown that the most influential parameters are respectively the rotational speed and weld speed.
