【 摘 要 】

An integrated model of phase transformations is proposed, which unites the model of changes in the temperature fields of the workpiece during welding and subsequent cooling, as well as a simulation model of phase transformations that occur during cooling of the steel. The developed method allows predicting the amount of residual δ-ferrite in the structure of the weld of austenitic stainless steel, which is necessary to justify the welding conditions.
