Abstract
Development of a diagnostic model for monitoring welding production of nuclear power plant equipment
Incoming article date: 17.12.2025This paper presents the results of research into the synthesis of a mathematical model for the welding process of critical power engineering structures. To quantitatively assess the condition of welding components, an entropy approach is proposed, allowing for the study of objects taking into account the stochastic nature of the processes occurring within them. An information and analytical system is proposed as a means of obtaining information, enabling measurement procedures to be performed under real production conditions. Electrical signals of welding current and voltage are measured. In the first stage, the signals are converted into time series and subjected to entropy parameterization. Next, the condition is monitored using a vector entropy model. The model is constructed based on a procedure for comparing vector entropies characterizing the states of components from the previous and current welding processes.
