N2 - A computer model for the prediction of weld structure and phase composition for fusion welding process based on a modified Schaeffler diagram has been developed. The model takes into account the non-equilibrium crystallization of metals and strengthening phase formation processes in the weld with any level of alloying and permits calculation of the quantities of each phase formed regardless the concentration level of alloying components. Chemical composition of new flux-cored wire for build up layers with good shock-abrasion resistance properties using the proposed model have been calculated. A calculated phase microstructure of the build up weld made by the computer was presented. Flux-cored wires were fabricated from a cold-rolled ribbon (1008 steel) and filled with a powder mixture. Low carbon steel (A 516) was used as the base metal. The samples were prepared by 3-layered build up. The prepared samples were tested using elemental analysis, hardness measurements, and metallographic tests were performed. The results of the mentioned tests confirmed the correct calculation of the model.
