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, whilst 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 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.

Abstract: 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.

Abstract: A method of manufacturing a component is disclosed. The method includes depositing a material on a removable form structure having geometry corresponding to an internal space of the component. The material is deposited on the removable form structure by an additive manufacturing technique. The method includes removing the removable form structure to obtain a pre-machined component, and then machining the pre-machined component to manufacture the component having the internal space.

Abstract: A method of forming a layer of cladding material on a component includes performing a metal deposition process to deposit cladding material onto a surface of the component and onto a mold member. A metallurgical bond is formed between the cladding material and the component, but not between the cladding material and the mold member. The mold member may be removed after the metal deposition process, and the layer of cladding material can be processed to modify its shape.

Abstract: The present disclosure relates to a method for inspecting worn surface of camshaft lobes of a camshaft. The method includes providing a laser scanning device at a predetermined distance from the worn surface of the camshaft lobes, the laser scanning device being configured to scan and gather data. The method includes moving the laser scanning device along a reference axis parallel with an axis of rotation of the camshaft and repeating the scanning for each camshaft lobe of the camshaft. The method includes generating a set of data points for each camshaft lobe. The method further includes determining a maximum depth of the worn surface based on the set of data points. The method also includes selecting the camshaft lobes for a remanufacturing process, if the maximum depth of the worn surface for each measured camshaft lobe is less than or equal to a predefined tolerance limit.
