MODELING AND ANALYSIS OF TECHNOLOGICAL PROCESS OF WELDING OF TANK COURSE
The article describes the results of modeling and optimization of the technological process of finite element welding using the ESI Visual Weld software. The object of the study is steel thin-sheet elements of the vessel body design. Various methods and modes of welding the structure have been analyzed, and defects have been identified and residual stresses in the structure have been determined. The distribution of thermal fields and stresses is shown, their graphic analysis is performed. Recommendations are given to reduce residual stresses after welding.
