  • Patent number: 12275093
    Abstract: A method of attaching a tube having a tube wall defining a tube channel therein to a workpiece having a workpiece wall. A workpiece opening defined by a workpiece opening wall surface is formed in the workpiece wall. A tube engagement surface is formed on the tube wall for engagement with the workpiece opening wall surface. A workpiece heated portion in the workpiece, and a tube heated portion in the tube, are heated in a non-oxidizing atmosphere by energized heating elements to a hot working temperature. The tube is subjected to an engagement motion, moving the tube engagement surface relative to the workpiece opening wall surface. While the heated portions are at the hot working temperature, and while the tube is subject to the engagement motion, the tube engagement surface is pressed against the workpiece opening wall surface, for plastic deformation of the heated portions, to create a metallic bond.

  • Patent number: 12263542
    Abstract: Properties and performance of weld material between metals in a weldment is controlled by modifying one or more of the nitrogen content and the carbon content to produce carbide (e.g. MC-type), nitride and/or complex carbide/nitride (e.g. MX-type) type precipitates. Fusion welding includes (i) adjusting shield gas composition to increase nitrogen/carbon gas and nitride/carbide species, (ii) adjusting composition of nitrogen/carbon in materials that participate in molten welding processes, (iii) direct addition of nitrides/carbides (e.g. powder form), controlled addition of nitride/carbide forming elements (e.g. Ti, Al), or addition of elements that increase/impede solubility of nitrogen/carbon or nitride/carbide promoting elements (e.g. Mn), and (iv) other processes, such as use of fluxes and additive materials. Weld materials have improved resistance to different cracking mechanisms (e.g., hot cracking mechanisms and solid state cracking mechanisms) and improved tensile related mechanical properties.

  • Patent number: 12251772
    Abstract: A method of securing an insert in a preselected region of a workpiece. An opening wall is formed in the workpiece with an opening wall surface defining an opening to produce a remainder segment of the workpiece. The opening encompasses or coincides with the preselected region. An insert is provided to fit in the opening. An insert heated portion and a remainder segment heated portion are heated to a hot working temperature, at which they are plastically deformable. While the insert is subjected to an engagement motion, to move the insert relative to the remainder segment, an insert engagement surface of the insert is pressed against the opening wall surface, for plastic deformation of the insert heated portion and of the remainder segment heated portion, creating a metallic bond between the insert and the remainder segment. The insert and the remainder segment are allowed to cool, to bond them together.
