  • Patent number: 10858997
    Abstract: A method of joining includes applying braze to a braze reservoir in a first component. A second component is engaged to the first component, wherein a joint location is defined between the first and second components. A wicking structure provides flow communication from the braze reservoir to the joint location. The method also includes joining the first and second components together at the joint location by applying heat to the braze to flow the braze from the reservoir through the wicking structure to the joint location to form a braze joint at the joint location.

  • Patent number: 10352109
    Abstract: A technique facilitates coupling of sections of tubing, e.g. a casing and a liner. A first tubing is positioned at a desired location, and then a second tubing is deployed through an interior of the first tubing until predetermined regions of the first tubing and the second tubing are in proximity to one another. A molten metal material is located between the first tubing and the second tubing at the predetermined regions. The molten metal material is then solidified to secure the second tubing to the first tubing.

  • Patent number: 9752708
    Abstract: An exhaust system is manufactured in the following manner. Initially, a plurality of pipe sections are put into each other with a clearance fit, so that connecting points are formed, at which two pipe sections overlap each other. The pipe sections then are calibrated at the connecting points, so that a narrow gap is obtained. Subsequently, the connecting points are soldered. The exhaust system thus includes a plurality of pipe sections which are put into each other and soldered to each other. Outer pipe sections of the plurality of pipe sections are calibrated.

  • Publication number: 20140327239
    Abstract: An improved coupling system for joining two items together, typically in the form of copper pipes, to other copper pipes, or in the form of other fittings, includes a pair of flange couplings, each of which is independently secured to one of the items to be joined together so that when the two flange couplings are securely joined to each other by suitable fasteners received through fastening apertures in the two flange couplings, the two items are sealingly joined to one another to form a substantially water tight junction. The improvement being that the bare metal parts of the ferrous components of the coupling are coated with a protective coating, such as a copper coating, so that there is no direct contact between two dissimilar metals thereby inhibiting or preventing corrosion of the metal components of the coupling due to electrolytic or galvanic action arising from direct contact between the two dissimilar metals.

  • Patent number: 6918617
    Abstract: A soldered feed-through device that is inserted into a bulkhead opening has one or more sets of laterally protruding and symmetrically distributed teeth that cut through the bulkhead material as the feed-through is inserted into the bulkhead opening. The teeth automatically center the feed-through device within the bulkhead opening and resist tilting of the feed-through and its through-hole conductor so that application of solder to the area between the feed-through and the inner periphery of the opening produces a solder joint having uniform radial thickness of preferably about 0.14 mm (0.0055 in.).
