Calculation of the Heat Affected Zone Coupled with the Arc Simulation in Tig Welding Process Considering the Marangoni Effect
Keywords:tungsten inert gas welding, constricted arc, arc simulation, weld pool
The present article is focused on a tungsten inert gas (TIG) welding process in two operation regimes, a normal and a constricted one. A computational model is applied for simulations of the liquid weld pool and the heat-affected zone of the workpiece coupled with a simulation of the welding arc. Welding experiments are used for model validation. Temperature profiles obtained from high-speed images with spectral filters correspond well with arc simulation results for both operation regimes.
