Abstract

The methodology of prediction of the heat-affected zone (HAZ) microstructure in a multiple-bead welds of the two layers of 1.25Cr-1Mo-0.25V steel using SMAW deposition process is presented. A computer program was developed to calculate extension zones of interest of two layer multipass weld-beads HAZ and predict a percentage of HAZ coarse grains refinement for determined welding parameters, preheating temperature and weldbead overlap. The computer model has been validated by experiment depositing a series of two-layer weld-beads getting reasonable concordance of model prediction and measured during experiment structural HAZ distribution. Keywords HAZ microstructure. Numerical simulation. Cr-Mo-V steel. Two-layer multipass weld-beads
