Build‐up metal for shock‐abrasion resistance was the focus of this work, where the mathematical model of physicochemical high‐temperature processes developed by the authors in their previous works was used. A computer program based on the model permitted forecasting of the required chemical composition and structure of the build‐up metal. 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 specimens were prepared by 3‐layered build‐up. The prepared specimens were tested using light microscopy, scanning electron microscopy (SEM), energy dispersive X‐ray analysis (EDS), hardness measurements, and shock‐abrasion resistance measurements. The results of the above‐mentioned tests confirmed the correct calculation of the model and the good shock‐abrasion resistance of the suggested build‐up metal.
