受运输条件限制，三门峡水电站６号机组的ＺＧＯＣｒ１３Ｎｉ４ＭＯ全不锈钢转轮为分瓣制造，在工地组焊成整体。为严格控制焊接收缩量和焊接应力及变形，保证焊接质量，主要采取了把合水轮机主轴，限制径向和轴向变形；采用对称、分段、退步、多层、多道、小线能焊接方法；单面焊双面成型技术封底，取消碳弧气刨清根；以及层间采用锤击法消应等措施。封底焊条为Ａ２３７不锈钢焊条，直径３．２ｍｍ；主焊缝焊条为Ｍ８３１Ａ不锈钢焊条，直径４．０ｍｍ。焊后检查结果表明，焊缝无裂纹、无咬边现象，质量符合美国ＡＳＭＥ标准；转轮变形小于允许值，焊接质量良好。
Limited by the transport conditions, Sanmenxia Hydropower Station Unit 6 ZGOCr13Ni4MO all stainless steel wheels for the manufacture of sub-group welding in the field as a whole. In order to strictly control the amount of welding shrinkage and welding stress and deformation, to ensure the quality of welding, the main take the turbine shaft, limiting radial and axial deformation; symmetrical, segmented, regressive, multilayer, multi-channel, small wire can be welded Method; single-sided welding double-sided molding technology back cover, cancel carbon arc gouging clear root; The back electrode is A237 stainless steel electrode, diameter 3.2mm; the main weld electrode M831A stainless steel electrode, diameter 4.0mm. Post-weld inspection results show that the weld without cracks, no undercut phenomenon, the quality of the United States ASME standards; wheel deformation is less than the allowable value, the welding quality is good.
