The article presents differences in the character of thermal cycle changes in welding conditions compared with the cycle of a traditional heat treatment, discusses the essence of austenite transformations in steels in welding conditions compared with heat treatment conditions, presents test results in the form of CTT-W diagrams (i.e. for welding conditions) for X10CrMoVNb9-1 (T/P91), X10CrWMoVNb9-2 (T/P92), X12CrCoWVNb12-2-2 (VM12-SHC), 7CrMoVTiB10-10 (P24), 10CrMo9-10 and S355JR grade structural steels and compares CTT-W diagrams with CCT diagrams for typical heat treatment conditions.
