| 摘要 |
A turbine rotor is formed from two rotor segments that are composed of different low alloy 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 on one of the flanges and a filler material welds the clad layer to the other flange to form a composite turbine rotor. |
