Abstract: A process for repairing a section of a rotatable shaft is disclosed. The section of the rotatable shaft has a surface portion having a surface parallel to an axis of rotation of the rotatable shaft and axial ends perpendicular to the axis of rotation of the rotatable shaft. The process includes preparing a well region extending over a perimeter of the section and extending downward in the surface portion, depositing material into the well region to fill the well region using a welding process and displacing a portion of the material that was deposited in the well region. The well region has a bottom portion that is substantially parallel to the axis of rotation and includes opposing sidewalls. Each sidewall extends proximate to the axial ends of the rotatable shaft and directly adjoins a remaining portion of the surface portion.
