摘　　要：本文介绍了二滩机组的主要焊接部件定子机座和转子支架的制造工艺。机座采用大盒形筋结构 ,对于控制环板的平面度的效果比较明显 ,也增加了机座的刚度。转子支架的工地焊缝中立焊缝采用搭板连接的接头形式。中心体的立筋与支臂的立筋之间可以允许有较大的间隙 ,与传统的工艺相比 ,可以在中心体装焊后不再对立筋进行机加工 。This paper describes technology process of stator frame and rotor spider for Ertan power station. The selection of box type rib structure allows effective controlling of the platness of ring plate and increasing of the frame stiffness. Stiffener connection is used as the joint form for the vertical position welds in site wedling of rotor spider.Relatively large gap is allowed between the hub rib and the arm rib Compared with traditional technology process,machining cost is low,because it's not necessary to ma chine the rib after the assembly of the hub.
