Abstract
The invention concerns welded turbine rotors. It is characterized in that, n the elements constituting a welded rotor which consist of a blade bearing block having at least one axial protuberance, that axial protuberance is made of steel having a lower carbon and nickel content than the remainder of the element and is joined thereto by a transition zone also made of steel. The invention applies more particularly to high-power steam turbines.
