Abstract A turbine rotor is formed from two rotor segments that are composed of different low allay steels, one a high temperature alloy and the other a low temperature alloy. The rotor segments have cavities in confronting faces that form an annular flange at the outer surface, with the segments welded together across the flange. A clad layer is first welded an one of the flanges and a filler material welds the clad layer to the other flange to form a composite turbine rotor.
