Latest Patents

One of Amos's latest patents is the "Turbine Rotor Modernization and Repair Method." This invention relates to an improved method for repairing damaged or worn surfaces of turbine components or upgrading older designs to new, improved designs. The method applies to both high-pressure and low-pressure turbine component applications. It includes depositing a plurality of individual spaced apart weld volumes onto a prepared surface of a turbine rotor. These individual spaced apart weld volumes form individual fingers without the need to machine them from a single rectangular weld volume. Multiple weld volumes are formed concurrently with a space maintained between each weld volume using multiple torches, addressing the problems normally associated with closely spaced welding arcs. Each individual spaced apart weld volume is formed by a plurality of layers of weld metal, with each layer being formed from a single oscillating weld bead to achieve a predetermined width. The invention provides for reduced cycle time for repair work by using multiple torches simultaneously without causing arc instability.

Another significant patent is the "Linear Friction Welding of Steeples and Device Thereof." This invention provides a blade-rotating device for rotating a plurality of radially-oriented blades. The device has a portion, such as a disc or a rotor disc of a turbine, for rotating the blades with the portion having an outer cylindrical surface. The device also includes a plurality of steel steeples, each having a steeple base and two opposite grooved steeple sides extending therefrom. The steeple bases are linear friction welded to the outer cylindrical surface in an approximately longitudinal direction, allowing the blade bases to engage with the steel steeples.
