Three-Dimensional Temperature Field Numerical Simulation of Twin-Arc High-Speed Submerged Arc Welding Process Based on ANSYS
Based on analysis of submerged arc welding arc heat source model and droplet heat inputting uniform distribution, ANSYS parametric design language was applied to develop sub-program for loading moving heat sources. ANSYS software was used to calculate the temperature fields. In the same welding conditions, weld seam width and depth value of experiments and simulation are contrasted, the biggest error was below 5%. The influence of different welding speed to molten pool temperature of twin-arc submerged arc welding was analyzed, it obtained results that temperature field distribution of twin-arc submerged arc welding changes more gentle than single arc submerged arc welding in condition of increased welding speed, it was helpful to the further analysis of molten pool dynamic behavior and weld seam shape factors of twin-arc high speed submerged arc welding.
