  • Patent number: 8776343
    Abstract: During implementing a composite metal part by compaction of an insert having reinforcing fibers in a metal body or container, gas used for compaction may enter the cavity formed in the container for receiving the insert between a lid covering the insert and the container, which can prevent or degrade compaction and diffusion welding of fiber sheaths of the insert therebetween and/or with walls of the cavity. To solve this problem, the present method includes initiating isostatic compaction by a phase including raising and maintaining temperature, followed by a phase including hot-feeding pressurized gas, and machining an assembly to obtain the part. The temperature raising phase includes a diffusion pre-welding of material rigidly connecting the pressure-adjusted walls of the lid and the container. The method can be used for designing parts having a tensile and compression resistance, such as parts for aircraft landing gear.

  • Publication number: 20120061453
    Abstract: A method for producing tailor-made sheet metal strips, in particular steel strips, in which at least two sheet metal strips of different material quality and/or sheet metal thickness are welded to one another along the longitudinal edge in a continuous process. In order for the sheet metal strips produced by such a method to exhibit a relatively high level of weld seam strength, uncoated sheet metal strips are used in accordance with the invention as sheet metal strips to be welded. The tailor-made sheet metal strip formed of the uncoated sheet metal strips as a result of welding is then coated.

  • Patent number: 8109431
    Abstract: A method of joining a first article to a second article using adjustment features located in an assigned scrap portion of the first article. The first article can be a casing for a turbine engine the first article being the casing skin and the second article a flange. The adjustment features are springs that can be stretched to increase the circumference of the skin. Following the correct sizing of the skin and joining to the flange the attachment features are removed along with the assigned scrap portion of the skin.

  • Patent number: 8074866
    Abstract: A system and method for repairing turbine vane attachment systems in a turbine engine. In at least one embodiment, the invention may be directed to a system and method for repairing wear on a diaphragm hook fit configured to attach diaphragm airfoils, such as stationary turbine vanes, to a combustion turbine case. The restoration system may be formed from a carriage assembly having an assortment of material processing implements usable to build up material in the worn locations of the turbine vane attachment system to reestablish a diaphragm hook fit within the specified tolerances. The restoration system may be configured so that the restoration process may occur without removing a rotor assembly, which can reduce the repair time by about two weeks. Thus, use of the restoration system can result in a significant time and cost savings.

  • Publication number: 20110294636
    Abstract: A roll (1) for supporting and conveying hot material, including a roll element that has a roll jacket (2) made of a basic material and a wear coat which is applied to the basic material by means of a surface welding process (4) using a welding additive which surrounds the surface of the roll jacket. In order to increase the service life of the wear coat, improve the resistance to wear, and reduce the cost for producing the welded-on surface. The basic material of the roll jacket (2) is steel and contains up to 0.45 percent of C. The welded-on surface (4) is designed as a single-layer weld, and the wear coat contains 12.5 to 14.0 percent of Cr at least in an external zone that surrounds the surface of the roll jacket. Also disclosed are a method for producing the roll (1), a method for repairing a used roll (1), a welding additive and a welding rod for producing the welded-on surface.

  • Patent number: 8042723
    Abstract: Provided is a method of repair which method is capable of holding a molten brazing material at the bonding portion when a component is bonded with a brazing material to an inclined or to a curved surface. The method of repair repairs by brazing a repair portion in which a crack has developed and which needs repair, wherein a brazing material support (4) holding in the interior thereof a molten brazing material (5) is brought into contact with the repair portion, and under the condition that the brazing material support (4) is in contact with the repair portion, the molten brazing material (5) is solidified. Under the condition that the brazing material (5) in a powder form is brought into contact with the brazing material support (4), the brazing material (5) can be melted by heating to a temperature at or above the melting point of the brazing material (5).
