The numerical simulation technique is a kind of numerical solution to mathematical model based on computer programs. For some engineering problems such as temperature field and stress field in welding that normally cannot be addressed by analytical or experimental method, numerical simulation technique can conduct analog computation on these problems so as to obtain the approximate solution. As a highly complex process, the welding process involves processes of heat transmission, metal melting and solidification, welding residual stress and distortion. In addition, since the welding thermal process is of great significance to the welding terminal cracks control, and the improvement of welding quality and production efficiency, the welding numerical simulation technique, adopting finite element analysis software, can conduct analog computation on welding thermal process and obtain the approximate solution to welding process, which plays a vital role in the optimization of technical parameters and structural design and in improvement of practical productivity. |
