Development of Welding Distortion Analysis Method Using

There are two ways of conventional thermal distortion analysis. One is thermal elastoplastic analysis and the other is equivalent forces method based on inherent strain. The former needs exorbitant analysis time, while the latter cannot obtain stress results and requires more time with loads modeling on curved plates. To solve those time-consuming problems, a new kind of thermal distortion Distortion - Corrective Techniques - TWIThe dangers of using thermal straightening techniques are the risk of over-shrinking too large an area or causing metallurgical changes by heating to too high a temperature. As a general rule, when correcting distortion in steels the temperature of the area should be restricted to approximately 60° - 650°C -

Effect of controlled rolling/controlled cooling parameters

3.1 Thermal-mechanical simulation of TMCP process Nine steel specimens with the size of U10 mm 9 15 mm are cut from cast slabs and nal hot rolled to a cylinder with a height of 4 mm through a two-stage controlled rolling process, as shown in Fig. 1. The results of the experiments and the analysis of orthogonal test are shown in Table 3. Effects of initial condition of steel plate on welding The effects of initial deflection and initial residual stress in steel plate on the out-of-plane deformation and residual stress due to welding are investigated from analysis results of thermal elastic-plastic FEM modeling with large deflection theory. Initial residual stress due to plate forming has very little effects on welding deformation and welding residual stress.
