Abstract
Certain features of simulation of gas-shielded consumable-electrode multi-pass welding with item preheating are considered. The paper shows the differences of the improved model from that of single-pass welding (SimWeld program package). Weld geometry and temperature cycles obtained through simulation, are in good agreement with the experimental data.
Keywords: multi-pass arc welding, consumable electrode, shielding gas, simulation, heat mass transfer, temperature field, form of weld, modulation
