A new model of heat source applicable to TIG welding is proposed. The model uses three calibration parameters - efficiency, effective heating spot radius and heat source concentration factor. Based on the experimental results, the model was calibrate

A 3D multi-scale and multi-physics numerical model has been developed and validated to predict the occurrence of hot cracking during fusion welding of Al-Mg-Si alloys. The new model consists of four modules: (I) a welding solidification module that c

En soudage par friction malaxage (Friction Stir Welding, FSW), l’outil est l’acteur principal de l’opération. Dans sa configuration conventionnelle, l’outil FSW n’est pas considéré comme un consommable lors du soudage des alliages d’al

Numerical simulation of nanosecond pulsed laser welding of eutectoid steel components

Autor: Leonardo Orazi, Giovanni Tani, Giampaolo Campana, Alessandro Ascari, Alessandro Fortunato, Gabriele Cuccolini

This paper considers the micro-closed seam laser welding of two nearly eutectoid carbon steel grades. These materials are difficult to weld due to their poor ductility. In particular, in closed seam welding, the laser beam starts and finishes in the
