Abstract

At the present stage of welding production development an important condition of its perfection is creation of highly efficient methods and means of simulation and modeling of welding processes, their control and optimal management in real time. Great attention is paid to applying modern means of mathematical modeling and computer simulation, which have become a powerful tool of research and understanding thermo-mechanical processes taking place in fusion welding. However, applying methods of mathematical modeling is hindered by a lack of sophisticated models of processes and phenomena taking place in welding. Making high-quality welds of alloyed steels is a difficult engineering problem, and even minor deviation in technology of welding brings to a great variety of microstructures and changing of operating properties of welds, which makes it difficult to forecast and model them. In spite of rapid development of mathematical modeling and computer simulation of welding processes and a great variety of specific models, there is no model yet which would profoundly describe the process of fusion welding. At present the development of computer-aided all-factor model of fusion welding of alloyed steels taking into account peculiar properties of different methods (manual arc welding, shielded gas machine welding, SAW) is being finished. The model can be used to investigate the influence of processing factors on the processes in the welding pool, structure and operating properties of welds, forecasting operating properties of welds in industry and engineering design of welded structures and in training students of technological higher educational institutions.
