  • Publication number: 20110009979
    Abstract: This invention discloses a method, using pure niobium as a transient liquid reactive braze material, for fabrication of cellular or honeycomb structures, wire space-frames or other sparse builtup structures or discrete articles using Nitinol (near-equiatomic titanium-nickel alloy) and related shape-memory and superelastic alloys. Nitinol shape memory alloys (SMAs), acquired in a form such as corrugated sheet, discrete tubes or wires, may be joined together using the newly discovered joining technique. Pure niobium when brought into contact with nitinol at elevated temperature, liquefies at temperatures below the melting point and flows readily into capillary spaces between the elements to be joined, thus forming a strong joint.

  • Publication number: 20110000953
    Abstract: A laser, aimed at a flyer plate tab, causes optical energy to be directed at the tab, specifically, at a top surface thereof. Energy impacting the tab accelerates the tab out of an initial bent position, straightening it into an impact with a target sheet. The impact occurs in excess of 100 m/s, resulting in a metallurgical bond between the tab and the target sheet. The laser preferably strikes the top surface in a normal direction, based upon an initial angularity of the tab relative to the target. The laser emission, preferably in the range of 1 to 100 Joules delivered in a microsecond, may be augmented by an ablative layer on the top surface or a transparent covering on the top surface that reacts against the expanding gas from ablative activity on the top surface. The weld is formed without physical contact between the welding device and the tab.

  • Publication number: 20100294484
    Abstract: A swelling element packer is made with internal rings that are either split or scrolled. After the swelling element is built on a temporary mandrel a longitudinal seam of a variety of designs is cut through the element. This allows the rapid deployment of the element on the tubular that will be a part of a string and will serve as the final mandrel. The assembly is then magnetic pulse welded or crimped so as to urge the open ends of the rings to move toward each other and become secured to each other and further opening the possibility of attaching parts on the ring itself to the underlying tubular by displacing or otherwise removing the swelling material that was between the ring and the final mandrel when the magnetic pulse process began. The rings can be embedded wholly within the element or can extend beyond the opposed ends or combinations of the two.

    Abstract: A pair of metallic components are co-axially aligned prior to full energization of the magnetic pulse welding inductor to provide for improved control of the magnetic pulse welding process. To accomplish this, either or both of the components are supported in a floating manner. An electromagnetic coil is then energized so as to generate a magnetic field of relatively small intensity within or about one of the components. This relatively small intensity magnetic field exerts a relatively small force on the two components, causing them to move to a co-axially aligned position relative to one another and to the coil. Then, while the components are co-axially aligned, they are subjected to a magnetic field of relatively large intensity for the purpose of permanently joining such components together. This relatively large intensity magnetic field exerts a large pressure on one of the two components, causing it to deform toward the other of the two components at a high velocity.

    Abstract: An apparatus for supporting a workpiece, such as a yoke having a body portion and a pair of opposed yoke arms, during a magnetic pulse welding operation includes a lower jaw, an upper jaw, and a support pin extending therebetween. During the magnetic pulse welding operation, the lower and upper jaws of the support apparatus engage the opposed yoke arms, and the support pin extends through respective openings formed through the opposed yoke arms. The support apparatus can also include a counter die that is disposed between the lower jaw and the upper jaw and has an arcuate recess formed therein that receives the outer portions of the opposed yoke arms therein. Lastly, the support apparatus can further include a pair of positioning rails that engage the body portion of the yoke. As a result, the support apparatus prevents deformation of the opposed yoke arms and absorbs shock waves that can be propagated through the yoke during the magnetic pulse welding operation.

  • Publication number: 20040256441
    Abstract: A composite structure comprises several layers of various materials which are to be united by welding and simultaneously consolidated. The method resides in that the densities and moduli of elasticity of the various layers are adapted by composition, shape, state and temperature in such a way that the velocity of sound is considerably modified upon penetration of the composite structure. A shock wave is applied to one or both sides. This shock wave breaks down into harmonic vibrations that can sum up, concentration of energy resulting on the respective interfaces, ensuring the union within and between the layers.

  • Patent number: 6749101
    Abstract: A method for manufacturing x-ray tube parts wherein metallic pieces are explosively bonded together to establish a high strength, stable union between them. The x-ray tube parts may then be milled from the bonded metallic pieces. The explosion bonding process creates only discrete intermetallic components in the joint region instead of a continuous, weakening intermetallic layer common in brazed joints. An explosion bond joint is characterized by a wavelike interface, thereby increasing surface area over which the components are bonded and further increasing bond integrity. Rotor sleeves and other tube components may be manufactured using this method.
