RISK ANALYSIS ON TECHNICAL SAFETY OF PRODUCTION OF WELDED STRUCTURES USING NON-DESTRUCTIVE TEST AND TECHNICAL DIAGNOSTICS

The object of research is welded structures and their production. There is always a risk, but it is obvious that making decisions to minimize and eliminate it requires a structured and systematic approach. For example, top, middle and line managers need to constantly analyze the risks associated with the dangers that arise in very difficult situations in the welding industry. An algorithm for the formation of risk during the operation of welded structures is constructed. A process approach is proposed with the aim of analyzing deviations in the design, production and maintenance processes. The parameters of the ultimate state of the welded structure from mechanical stresses and the quality indicators of corrosion effects are determined. The calculated formulas for the speed (probability) of reaching limit states from mechanical stresses are selected. To analyze the combination of actions, it is recommended to use the Bayesian grid method. It has been established that one of the main tasks of the welding production quality management system according to DSTU ISO 9001:2015 is to ensure the identification of potential inconsistencies in the welding production system and to prevent their detection through risk management. Deviations of the processes of the management system are the reasons for the formation of a shortage of products and the risk of an emergency at work. The success of risk management will depend on the effectiveness of the management structure, which provides the rationale and measures that integrate it throughout the welding plant at all levels. The structure helps to implement effective risk management through the production of risk management processes and non-destructive testing and technical diagnostics at different levels and within the specific context of the enterprise. The structure ensures that the risk information obtained in the risk management process appropriately is used as the basis for making decisions and appointing those responsible for the result at all relevant levels of welding production
