Zusammenfassung:	The present invention relates to a method for welding rotors for power generation. More particularly, the present invention relates to a method for welding rotors for power generation to greatly reduce manufacturing time and cost. A method for welding rotors for power generation according to one embodiment of the present invention includes a step of providing rotor disks (26); a step of stapling the disks (26) in upper ends, respectively; a step of increasing the height of a wedding part by narrow gap TIG welding; a step of completing the welding by filling an external SAW welding gap; and a step of testing the welding parts of the rotor.
