座环是水轮机的重要部件，它既承载着机组的重量，又控制着水的流量与速度。轴流式水轮机座环通常为双环板，固定导叶采用中空结构，各瓣体经通用模具成型后组焊成一体。其成型和焊接面临很大的技术难题，文章着重讨论单环板焊接式座环的装配焊接工艺。

The seating ring was an important part of hydraulic turbine, which not only bore the weight of the whole unit but also controlled the water flow and speed. Double-ring plate were the conventional structure of axi-al flow hydraulic turbine seating ring. Usually, the fixed vane was of hollow construction while the steel plates were welded and integrated into a whole unit after shaping. But the welding and shaping encountered many technology problems, thus, the assembly and welding procedure of the single seating ring were discussed emphatically.
