Моделирование сварочного нагрева изготавливаемых соединений энергетического оборудования

Abstract

Ресурс эксплуатации сварных соединений энергетического оборудования в значительной мере зависит от их структурного состояния. Целесообразно, для получения исходной структуры сварных соединений с улучшенными качественными характеристиками, производить моделирование сварочного нагрева при их изготовлении. Затем, на основе данных моделирования путем подбора параметров режима выполнять сам процесс сварки, позволяющий получать качественную исходную структуру сварных соединений с возможно меньшей структурной неоднородностью.

The service life of welded joints of power equipment largely depends on their structural condition. It is advisable, to obtain the original structure of welded joints with improved quality characteristics, to simulate the welding heat during their manufacture. Then, on the basis of modeling data by selecting the mode parameters, perform the welding process itself, which allows to obtain a high-quality initial structure of welded joints with the least possible structural heterogeneity. It should be noted that welded joints with the obtained improved quality characteristics have a crucial function during the operation of the whole complex of power equipment. It is found that modeling the welding process is an important part in the manufacture of welded joints of power equipment. Simulation of welding heating allows to obtain the structure of welded joints with improved quality characteristics. When determining the required design temperature in welded joints, it is possible to determine the conditions for the formation of their optimal initial structure with improved quality characteristics. The development of this model for modeling the welding temperature heating of the compounds being made is applied in the manufacture of especially important and important structures of power equipment, which is very necessary and relevant.
