The article deals with the approach to an evaluation of steel resistance to formation of cold cracking (CC) based on the integrated assessment of properties of structure determining the steel capability to resist CC and the mathematical model for modification of these properties under the welding thermal cycle. The possibility to apply the proposed approach is demonstrated by the example of prediction of variation of 30ХН3М2FА steel resistance to CC under multi-layer welding.
