    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.

    Abstract: A method for laser cladding a material onto a surface of a machine component using a laser scanning head with laser scanning optics is disclosed. The method includes forming a molten bead of cladding material by directing a beam with the laser scanning optics over a bead scan on the machine component. The method also includes directing the beam with the laser scanning optics over a secondary scan on the machine component, the secondary scan being offset from the bead scan at a predetermined distance on the machine component.

    Abstract: A pre-chamber for a fuel injector is disclosed. The pre-chamber includes a cylindrical body member extending axially from a first end portion to a second end portion opposite to the first end portion. The pre-chamber further includes a bottom plate located proximal to the first end portion of the cylindrical body member. The pre-chamber also includes a sacrificial member extending axially outwards from the second end portion of the cylindrical body member.
