Parametric study of the thermal behavior of cold metal transfer welding with titanium

Abstract

This work focused on enhancing the efficiency of thermal behaviour in the application of Cold Metal Transfer (CMT), especially for welding tough metals like titanium, which has the potential to impact the field of welding technology significantly. The investigation of the thermal behavior of CMT welding, carried out by means of parametric analysis, was a crucial step in this direction. This study, which was carried out with the assistance of numerical simulations with COMSOL Multiphysics, particularly emphasized critical factors such as plate thickness and welding power. The significance of this study in advancing our understanding of additive manufacturing in welding is highlighted by the results of the study. These results, which illustrate the effects of the specified influencing parameters through temperature distribution at various time intervals, 2D and 3D graphs depicting temperature evolution along the welding path, and the 2D temperature profile at (t=5s) across different plate thicknesses, have the potential to revolutionize the field of welding technology and bring about exciting new possibilities.
