ABSTRACT:
A rotor for a steam turbine for working steam and including at least two rotor parts welded to one another using a circumferential, annular weld zone, which is closed in the circumferential direction. A cooling channel system is formed in the rotor and has at least one inlet flow channel, at least one outlet flow channel and at least one cooling channel. In order to simplify the integration of the cooling channel system in the rotor, the weld zone surrounds a cavity which forms a component of the cooling channel system and through which cooling steam flows.
