| Abstract: | According to the analysis of manufacturing processes difficulty and failure in fixing and applying of the rail for replacing fan-shaped section, some techniques are adopted separately such as applying special fixture, controlling weld step, making use of welded stress to control welded distortion , and external force rectifying etc. And proper annealing craft is adopted. So welded distortion is controlled effectively and then producing and designing requirement is fulfilled. |
