摘要： Cladding and remanufacturing a machine component includes directing cleaning and welding beams split from an incident laser beam toward the machine component, and moving the machine component relative the cleaning and welding beams such that the welding beam trails behind the cleaning beam along a common travel path. A surface of the machine component is decontaminated by the cleaning beam, while a cladding material is melted via the welding beam such that upon solidifying the cladding material forms a coating metallurgically bonded to base material and previously deposited cladding material of the machine component.

摘要： A piston including a piston crown, the piston crown defining a combustion bowl with a bowl base and bottom surface. A failure initiation structure is provided on the bottom surface of the combustion bowl to initiate favorable fracture at predetermined loads. Such favorable fracture may lead to the a separation of a fragment of the bowl base from the combustion bowl when a predetermined load or pressure is exceeded within the combustion bowl.

摘要： A method for repairing a cylinder liner includes: placing a cylinder liner having a first inner diameter and a first outer diameter into a cavity of a confinement, the cavity including a cavity inner diameter that is substantially the same as the first outer diameter of the cylinder liner; heating the cylinder liner to a temperature at which the cylinder liner undergoes plastic deformation, causing the first inner diameter of the cylinder liner to decrease; and cooling the cylinder liner. The cooled cylinder liner has a second inner diameter that is less than the first inner diameter. An apparatus for repairing a cylinder liner includes a confinement having a cavity and a fluid passageway for controlling the temperature of the confinement, and a heating block for heating the cylinder liner when the cylinder liner is inserted into the cavity.

摘要： A method of remanufacturing a fluid end block of a well stimulation pump includes cleaning an interior surface of a body of the fluid end block. The interior surface defines a chamber, a plunger passage in communication with the chamber, an intake passage in fluid communication with the chamber, and a discharge passage in fluid communication with the chamber. The interior surface is made from a base material. The interior surface of the fluid end block is cold-worked to produce a compressive residual stress layer within the body. A coating layer made from a non-metallic material is applied to at least a portion of the interior surface of the body. The non-metallic material is different from the base material.

摘要： A laser cladding system includes a laser apparatus, a chamber, and a pump system. The laser apparatus is configured to generate a laser beam. The chamber includes an interior surface that defines a cladding area comprising a sealed volume. The chamber includes a window that is made from a laser-transparent material and is configured to allow the laser beam to pass therethrough into the cladding area. The pump system has a port in communication with the cladding area. The pump system is configured to selectively generate a vacuum pressure within the cladding area sufficient to evacuate gas from within the cladding area out through the port. The laser apparatus includes a laser head from which the laser beam is emitted and a robotic laser motion system configured to selectively move the laser head such that the laser beam moves relative to a reference point within the chamber.
