  • Patent number: 6648207
    Abstract: This disclosure describes a technique for fusing self-fluxing metallic coatings on non-cylindrical objects without the need to conduct the fuse operation in a vacuum furnace or some other type of protective environment. The technique consists of first applying the self-fluxing coating to the surface, then optionally applying a ceramic coating on top of the self-fluxing coating. The object is then submerged into a vessel containing a low-melting inert material. The aggregate is then heated, and as the glass becomes molten, it encases the object and protects it from oxidation. As heating continues, the fusing temperature is reached and the self-fluxing alloy becomes molten. The ceramic coating encases the self-fluxing alloy and acts as a mold. When fusing is complete, the aggregate is then slowly cooled to ambient temperature. The glass frit and the ceramic shell are then removed, and one is left with an object coated with a uniform thickness of a dense adherent fused coating on the surface of the object.

The initial heating, inter-rolling, thermal treatment and solution treatment, especially the latter two, are carried out at very high temperatures such as 1030° F. Each aforesaid hot rolling stage produces substantial metal thickness reduction. The improved sheet or plate product has a substantially reduced occurrence of reduced density features revealed in scanning electron microscope examination at 500× and exhibits improved (reduced) fatigue crack growth rate providing an advantage in aerospace applications such as fuselage skin, especially fuselage belly skin.

  • Patent number: 6527160
    Abstract: A method whereby a composite clad metal ingot can be produced for onward processing at higher temperatures which are sufficient to allow the properties of the substrate material to be adequately controlled to meet specific requirements. These higher temperatures are required to avoid the undue levels of work hardening which occurs at the lower temperatures previously employed because of the need to avoid the formation of deleterious intermetallics at the bonded clad substrate interface. Such intermetallics are formed at temperatures above approximately 850° C. and should they be present, will weaken or destroy the bond. The ingot, consisting of a steel or stainless steel substrate which is clad with a corrosion resistant metal, preferably of titanium, zirconium or their alloys, and containing an interlayer of high melting point metal of tantalum, niobium (columbium) or their alloys, is processed at temperatures above 900° C.

  • Patent number: 6513699
    Abstract: A process for the production of metal pipes is described in which a thin-walled metal band inclined toward cold spots is gradually formed into a slotted pipe, the longitudinal edges lying flush against one another are welded to one another, and the welded pipe is reduced in its diameter. The forming of the metal band into the slotted pipe is done by opposing metal forming rollers or forming cylinders cooperating pairwise. The forming rollers or forming cylinders guide the metal band to be deformed in its edge area with rolling friction between them. Therein the forming and guiding of the metal band is done with forming rollers and/or forming cylinders and the reduction with rollers whose surface hardness is greater than 100 GPa.

  • Publication number: 20020125301
    Abstract: A method and machine for deburring the burr which is formed when wires are butt welded is disclosed. The machine comprises a deburring head which has a pair of opposed deburring rollers mounted thereon. Each of the rollers has a milled surface formed therein. A linkage is connected to the rollers to cause the rollers to rotate when the linkage is moved between first and second positions. When the linkage is in its first position, the milled surfaces of the rollers face one another to enable the wires and burr to be positioned therebetween. As the linkage moves to its second position, the circumferences of the rollers engage the burr to roll out the same, thereby providing a substantially smooth, cylindrical surface where the burr was located. The method of deburring is also disclosed.

  • Patent number: 6443352
    Abstract: Resistance heating, preferably with applied pressure, is used to consolidate incremental volumes of material to produce a desired object in accordance with a description thereof. The joining of the material increments may occur in the solid state, liquid state, or ‘mushy’ state in conjunction an atomically clean faying surface between the increments without melting the material in bulk. Residual stresses are minimized, particularly in metal objects, by imposing a compressive residual stress on the surface of each deposited layer or increment, which offsets all or a portion of the tensile stress created as the next layer deposited above it cools. In terms of apparatus, a moving cathode is used to ensure uniform electrical current flow in an object with constantly changing geometry.

  • Publication number: 20020063145
    Abstract: Selectively reinforced blanks are used in a hydroforming process to produce completed components having a predetermined shape and sufficient structural integrity to perform their desired function. To reinforce those components, reinforcing patches are added to the blank prior to hydroforming. Planar patches can be bonded to planar blanks or arcuate patches can be bonded to tubular blanks. In so doing, the hydroforming process produces a complete component, which does not require additional manufacturing steps to reinforce it. Additionally, by selectively using the reinforcing patches, the overall weight of the component is not unduly increased.

At the time when the following material can catch up with the preceding material at an aiming position on the line, the following material is extracted from the heating furnace according to the result of the above prediction calculation. Control is carried out so that both of the preceding material and the following material finish the process at a preset speed. Also, the traveling speed of the following material is controlled according to the position and the speed of the tail edge of the preceding material in a section close to the catch-up position so that a distance between the tail edge of the preceding material and the leading edge of the following material be closed.

    Abstract: The invention relates to the joining of flat products of metallic materials to be interconnected overlapping. The joining takes place in a roll nip into which the flat products to be interconnected are introduced at an acute angle. Before they are pressed on one another in the roll nip, they are heated on their facing surfaces by radiation energy, but not melted. By a suitable profiling of at least one roller generated surface or one flat product the surface pressing is limited to the zone of the overlap joint and any flow of material transversely of the direction of the overlap joint is prevented.

The transfer speed of the succeeding material is controlled by adjusting at least the drive speed of the pinch rolls so as the front end of the succeeding material to contact with the rear end of the preceding material at a specified position in a travelling welder. the rear end of the preceding material is joined with the front end of the succeeding material by flash-butt welding using the travelling welder to form a continuous material while letting the travelling welder move at a speed synchronous with the transfer speed of the continuous material. The welded portion on the continuous material is ground and/or cut to remove burr therefrom.
