As an advanced manufacturing technology in an important component of the future development of welding technology from the "skills" to the "Engineering Science," and welding simulation technology development is an important sign [1]. In the field of welding simulation of the main targets, including temperature, displacement, strain, stress and so on. Welding and non-equilibrium heating and cooling process in the welding stress and deformation, not only affects the structure of the manufacturing precision welding, but the structure of the service have a significant impact on performance, stress and deformation of welding simulation is the ultimate target, also has been a welding Broad areas of concern and one of the important issues covered. However, the process of welding is the welding accurately calculate the basis of analysis of stress and strain, the process depends on the heat plus the heat distribution, welding materials, and thermal properties and welded pieces of the surrounding factors such as heat exchangers. Rykalin to the classic formula of points, lines, the distribution of welding heat to simulate all kinds of heat, there are certain limitations. Early on welding process has been staying in two-dimensional level [2] [3] [4]. In recent years, with computer technology and finite element technology development and related welding numerical simulation software development, the process of welding the three-dimensional numerical simulation research into the forefront of research in this area. However, due to the complexity of the welding process, welding process of three-dimensional numerical simulation in order to remain as a typical joint research, applied to the actual welding components there are still certain difficulties. In view of this, we have adopted a welding dedicated analysis software SYSWELD EAST Superconducting Tokamak in the vacuum chamber 2 1 / 16 segment welding process for the actual numerical simulation and simulation results and experimental pieces and Comparative Analysis of the real situation, made a similar Numerical simulation of welding pieces of the structure should be of concern to a number of issues.
