Abstract


The welding temperature field in the two-wire tandem submerged arc welding (SAW-T) process of X80 steel pipe using a three-dimensional (3D) finite element (FE) model. The thermal cycles and temperature distribution induced in the welding process were simulated using ANSYS software based on a moving heat source model. The technique of element birth and death method was also employed in the simulation of weld metal deposition. Influence of welding parameters on the distribution of temperature filed was analyzed.
