dc.description.abstractThis paper proposes a metal transfer model describing the dynamic growth and detachment process of the molten drop at the electrode tip in gas metal arc welding under an Ar-rich shielding gas. The proposed model simulates the metal transfer including the growth of the molten drop as well as the formation and break-up of the liquid bridge between the electrode tip and the molten drop based on the forces exerted on the molten and the second order displacement equation. The tapering effect occurring at the side of the electrode tip is considered to enhance the prediction performance in the high-current region above the transition current. Simulation results are compared with experimental results reported in the available literatures and they show good agreement from the low to high current region.-
