The purpose of this paper is to develop a methodology to fasten the process of setting-up the heat source parameters used in CWM simulations for LAHW technology. The methodology involve both the development of an analytic equation and a machine learning algorithm using the welding parameters (power and travel speed) and weld bead parameters (width and depth of the weld bead) as inputs. The results calibrated with experiments shows that the developed mathematical model is efficient to quickly set-up the heat source model for LAHW simulations.
