In order to minimize the welding deformation of diaphragm,the records of welding deformation are obtained through directly measuring size of the diaphragm with coroneted blades before and after welding.

蒸汽轮机自带冠静叶隔板是蒸汽轮机通流部分的静子部件 ,其制造精度直接影响到整个机组的效率。

ER410 welding wire selected and appropriate welding process should be taken,repair welding onsite of turbine diaphragm stationary blades,which material is 1Cr13.

针对汽轮机隔板静叶片出现的裂纹,对隔板静叶片的材料进行了焊接分析,提出了焊接方案,并对裂纹实施焊接,焊后进行修磨、检查,经检验证实选用ER410型焊丝、采用合适的焊接工艺,能成功地解决材质为1Cr13的汽轮机隔板静叶片的现场热补焊。
