Comparative analysis of bonding mechanism in solid state metal working processes
University of Palermo, Department of chemical engineering, management, computer, mechanical-DICGIM, Viale delle Scienze 128, 90128 Palermo, Italy
The Piwnik and Plata pressure-time bonding criterion was applied to Friction Stir Welding, Linear Friction Welding, Porthole Extrusion and Roll Bonding. A neural network was set up, trained and used to predict the bonding occurrence starting from the main field variable distributions calculated through specific numerical models developed for each process. The analysis of the results permitted to predict the occurrence of solid bonding and to highlight differences and analogies between the processes in order to obtain sound solid welds.
