More creep resistant turbine rotor, and procedures for repair welding of low alloy ferrous turbine components. |
摘要 |
<p>A method for repairing worn surfaces of Cr-Mo-V steam turbine components includes specified alloy compositions and welding procedures that minimize weld stresses and cracking. These alloys exhibit improved creep and fatigue properties and are preferably deposited using a gas tungsten arc welding procedure. Bead sequencing, cooling side plates and the use of run-off tabs are also disclosed for minimizing welding defects in turbine rotors and discs.</p> |
