The Simulation and Analysis of the New Type Large Vacuum Container Flange Welding Process

Abstract

Flange is the key part of the large vacuum container and its stiffness property affects the sealing effect and the stability of the container. Large flange welding process will have a greater impact on its structural strength. In view of the traditional way of forming large vacuum container flange has problems that processing and manufacturing are difficult, more material consumption, and poor stiffness, a new type of flange structure was support. The new design has hollow structure and the welding process of cover flange was simulated through the finite element method. After that, the stress and the deformation were analyzed and then the proper welding scheme was optimized.
