Abstract: The invention relates to a method for manufacturing a steam turbine low-pressure or medium-pressure module deflector, said deflector comprising an internal ring and an external ring as well as vanes, said method comprising a step of welding said vanes to said rings. The main characteristic of a method according to the invention is that the welding step is preceded by a step of automatically machining the ends of each vane to create a peripheral recess around each of said ends.

Abstract: A pinned root fixing arrangement of axial flow steam turbine rotor discs made of a low alloy that is less susceptible to stress corrosion cracking (SCC). Such an arrangement has a first ratio, which is defined as ratio of the axial breadth of the disc fingers and the sum of the axial breath and the axial breadth G of the gap between adjacent disc fingers, in the range of about 0.4 to about 0.6 and further has a second ratio, which is defined as the ratio of the length of the disc fingers and the blade fingers to the diameter, between 4 and 6.
