摘要：

A three-dimensional (3D) finite element (FE) model for the submerged arc welding process of medium thick plates was established. The welding temperature distribution for varying heat input was obtained by taking into account nonlinear relationships between temperature and thermal-physical properties. According to the characteristic temperatures of welding thermal cycles, widths of heat-affected zones (HAZs) were obtained. The widths of HAZs were also investigated through combination of metallographic examination and hardness measurements. The simulation prediction results and experimental results were compared and had generally good conformity.
