Modeling Weld Formation Mechanism of Automated Submerged Horizontal Position Arc Welding

Abstract:

An 3D mathematical model was established to illustrate weld pool development in the ASHPW (Automated Submerged Horizontal Position Welding) process. This model takes into consideration the spatial position characteristic of ASHPW, and used the heat transfer and mass transfer phenomena during welding process to explain the weld geometry mechanism in order to correctly design the bevel geometry. The final results show that the predicted geometry , such as the weld cross-section, weld width and weld cross section area, are in good agreement with experimental measurements.
