The present invention relates to methods and apparatus for turbine engine rotors and provides a method for welding two sections of a rotor (100) together, wherein each rotor section includes a welding surface, is provided. The method includes positioning the welding surface (114) of the first rotor section (102) substantially flush against the welding surface (116) of the second rotor section (104). The method also includes positioning the second section substantially flush against a flange circumscribing the first section such that a rabbeted joint (125) is defined therebetween.
