    摘要： Superalloy components are joined by mating a recess formed in one component with a corresponding projection formed in another component along a contact surface. The components are compressed along the contact surface and resistance heat welded to each other. Current is passed between the components at a selected flow rate and application time until localized melting occurs along the contact surface, and they are mutually affixed to each other. When repairing a damaged surface portion of a superalloy material component, the damaged portion is removed to form an excavated recess. A repair splice is formed, preferably of a same material with similar mechanical structural properties, having a mating projection with profile conforming to the corresponding recess profile. The splice and substrate are resistance heat welded under compression pressure until localized melting occurs along the contact surface, so that they are mutually affixed.

    摘要： A process for enhancing the bond strength of resistance welded joints between titanium alloy articles includes a first step of resistance welding two titanium alloy articles and a second step of heat treating the resistance welded titanium alloy articles in a vacuum or inert environment at temperatures in a range of 1675.degree. F. to 1825.degree. F. for a period of 15 minutes to 4 hours. The process of the present invention is particularly useful in providing efficient joining of face sheets to a honecomb core element.

    摘要： Methods and apparatus for positive displacement casting and/or for positive displacement bonding and, more particularly, for automatically forming, on a continuous, reproducible basis, fusion bonds devoid of structural and electrical defects between two or more workpieces by moving a heated electrode into the area to be bonded so as to uniformly heat and melt the portions of the workpieces to be bonded while, at the same time, displacing substantially all of the molten material from the area to be bonded into a storage area or reservoir surrounding the heated electrode where such molten material is maintained in its uniformly heated molten state, and then retracting the electrode so as to permit the molten material to return to the cavity formed by the electrode in the workpieces where such molten material is allowed to cool and solidify, thus forming a flawless bond between the workpieces-thermal or fusion bonds are made in accordance with the methods of the invention and with the apparatus of the invention by a combination of (1) elevated temperature levels sufficient to melt the material to be bonded, and (2) displacement of the molten material; as contrasted with more conventional techniques and/or apparatus which combine elevated temperature levels and pressure.
