Abstract: A prechamber ignition assembly for an internal combustion engine includes a base attached to a remanufactured prechamber ignition device at a base weld interface. The remanufactured prechamber ignition device includes a new tip formed of a tip material, and a root formed of a root material, with a used body formed of a body material disposed therebetween. The new tip is bonded to the used body at a tip weld interface and the root is bonded to the used body at a root weld interface.

Abstract: A method and system for sorting pistons with flaws is disclosed. In an embodiment, a piston with flaws is three dimensionally scanned and compared to a reference image to detect the location and geometry of the flaws. The location and geometry of the flaws are recorded and used to generate a surface condition score. The pistons are sorted based on the surface condition score being higher or lower than a set threshold value.

Abstract: A repaired piston includes a crown composed of base and welding filler materials, and having an annular rim extending around a combustion bowl. A finite number of repaired defects are within the annular rim, and have a spatial distribution limited by a multidirectional spacing parameter, and a size distribution limited by a unidirectional sizing parameter.

Abstract: 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.

Abstract: A method of remanufacturing a component having a heat treated hardened layer over a substrate material is disclosed. The method includes removing at least the heat treated hardened layer of the component to expose the substrate material. The method also includes providing a cladding material on the substrate material. The method further includes melting the cladding material via a laser beam to form a single layered coating with hardness greater than or substantially equal to hardness of the heat treated hardened layer, on the substrate material.

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.
