隔板的焊接要求汽轮机隔板由五部分组成(图1),各部材料见表1。在隔板的进出汽侧各有两道焊缝,对焊接变形的要求:出汽边高度误差≤±0.2毫米;出汽边面积(喉部高度)应
Welding requirements of the separator Steam turbine separator consists of five parts (Figure 1), the various parts of the material in Table 1. In the partition into the steam side of the two welds, the welding deformation requirements: the height of the output side of the vapor error ≤ ± 0.2 mm; out of the steam area (throat height) should be
