<p>A method of making a multiple alloy (100), multi-section welded turbine rotor (10) includes providing (110) a forged multiple alloy rotor section having an integral microstructure, the rotor section comprising a first alloy (30) having a first alloy composition (32) and second alloy (40) having a second alloy composition (42), a first weld face (34) comprising the first alloy (30) on a first end (36) and an a second weld face (44) comprising the second alloy (40) on an opposed second end (46). The method (100) also includes providing (120, 130) a first rotor section (50) comprising the first alloy composition (52) and a second rotor section (60) comprising the second alloy composition (62). The method (100) also includes welding (140) the first rotor section (50) to the first weld face (34) and welding (150) the second rotor section (60) to the second weld face (44).</p> |
