摘要： A welding method of a turbine diaphragm for joining a spacer having a plurality of nozzle blades to outer and inner wheels. The spacer and the outer or inner wheel are welded from both sides. At first or inlet side of the diaphragm where a motive fluid flows into the diaphragm, the spacer and the outer and inner wheel are welded so that weld depth from the first side will be at most 0.5 L, wherein L is a distance between the first side and the top of the nozzle blade. At the second or outlet side of the diaphragm, from which the motive fluid exits, the spacer and the outer and inner wheels are weld so that a welded depth from the second side will be at least 0.3 C, wherein C is height of the nozzle blades.
