Sažetak
The mathematical model for prediction of microstructure composition and mechanical properties of steel welded joint was developed. Finite volume method (FVM), was suitable to create integrated computer program for simulation physical processes during the welding. The computer simulation of hardness of welded joint is based on both, CCT diagrams and the thermo- kinetic expressions using linear alignment with the actual chemical composition. Microstructure and hardness of welded joint has been predicted based on calculated characteristic time of cooling from 800 °C to 500 °C, (t8/5). Distribution of hardness of welded joint has been predicted by conversion of calculated cooling times from 800 to 500 °C to the hardness. The algorithm for prediction of hardness in welding joint is based on real chemical composition. Results of steel welding were estimated by taking into account the process of reheating of workpiece during the welding. The established procedure was applied in computer simulation of heat treatable steel welded joint.
