| 20090074582 | METHOD FOR JOINING METAL COMPONENTS AND DEVICE FOR EXECUTION OF AN INDUCTIVE LOW OR HIGH-FREQUENCY PRESSURE WELDING METHOD - The present technology concerns one or more methods for joining of metal components especially components of a gas turbine, in which joining of the corresponding joining surfaces of the components occurs by means of an inductive low or high-frequency pressure welding and in which, before heating and joining of the components by means of inductive low or high-frequency pressure welding, sputter etching of the joining surfaces is carried out. The present technology also concerns a device for execution of an inductive low or high-frequency pressure welding method for joining the metal components, especially components of a gas turbine, with at least one induction generator and at least one inductor, as well as a component produced with the method according to the present technology. | 03-19-2009 |
| 20090108051 | Method for joining components - A method for joining components is described, in particular, for joining a rotor blade to a rotor base member when manufacturing and/or repairing an integrally bladed gas turbine rotor. The method includes the following steps: providing two components to be assembled, respectively joined to one another; providing a joining part; mutually aligning the two components to be assembled and the joining part such that the joining part is positioned as an insert between the two components to be assembled; driving the two components being assembled with the joining part being interposed therebetween in that the joining part to execute a linear, reciprocating motion in opposition to the two stationary components to be assembled in order to generate the frictional motion, further comprising exerting an upsetting force via the joining part on the joint zones between the two stationary components and the joining part, namely in a direction that extends essentially perpendicularly to the frictional motion. | 04-30-2009 |
| 20090113708 | Method for joining components - A method for joining components, in particular for joining a rotor blade to a rotor base body in the manufacture and/or repair of an integrally bladed gas turbine rotor, is disclosed. The method includes the following steps: a) providing two components that are to be connected, i.e., joined together; b) providing a joining part; c) aligning the two components and the joining part that are to be joined together such that the joining part is arranged as an insert between the two components that are to be joined together; d) connecting the two components with the intermediate arrangement of the joining part by moving the joining part with respect to the two stationary components that are to be joined together and in particular by exerting a compression force on the joining zones between the two stationary components and the joining part via the two stationary components. | 05-07-2009 |

The induction coil includes a meandering pattern section shaped around the at least one component in such a way that the section extends over at least a partial area of the at least one lateral face of the at least one component to be heated in the area of the at least one face to be heated. A device and method for inductive heating of at least one metallic component are also provided. | 05-21-2009 |
| 20090277541 | METHOD AND APPARATUS FOR HARDENING A SURFACE OF A COMPONENT - A method and apparatus for surface hardening parts is disclosed. To harden a surface of a part, a relative movement, or advancing motion, is established between the part and at least one sonotrode-like tool which is excited in the ultrasonic frequency range. The tool is aligned during the surface hardening in such a way to the surface of the part to be hardened that a tool axis running in the effective direction of the tool runs at an angle to the surface of the part to be hardened. | 11-12-2009 |
| 20100284817 | METHOD FOR PRODUCING A BLISK OR A BLING, COMPONENT PRODUCED THEREWITH AND TURBINE BLADE - A method for producing a blisk (bladed disk) or a bling (bladed ring) of a gas turbine is disclosed. The method includes the following steps: a) producing a turbine blade by joining a blade to an adapter element consisting of a metal material that is suitable for fusion welding, the adapter element being used to form a blade root of the turbine blade, and b) joining the turbine blade to a rotor disk consisting of a metal material that is suitable for fusion welding or to a rotor ring consisting of a metal material that is suitable for fusion welding in such a manner that the turbine blade is arranged on the outer periphery of the rotor disk or of the rotor ring. A component of a gas turbine or of a high-pressure or low-pressure compressor, especially a blisk or bling, and a turbine blade are also disclosed. | 11-11-2010 |

| 20110129347 | PROCESS FOR PRODUCING A JOIN TO SINGLE-CRYSTAL OR DIRECTIONALLY SOLIDIFIED MATERIAL - A process for producing a join between a first component and a second component is disclosed. The second component contains a single-crystal or directionally solidified material. A polycrystalline layer is produced on a joining surface of the second component for joining the second component to the first component. The joining surface of the second component is joined to the first component by friction welding. | 06-02-2011 |
| 20110133102 | METHOD AND ARRANGEMENT FOR DETECTING A SURFACE OF AN OBJECT - The invention relates to a method for optically detecting surfaces wherein strip patterns are projected onto the surface, images are captured, and the three-dimensional contour thereof is determined from the reproduction of the strip pattern on the surface of the object. The aim of the invention is to prevent reflections that interfere with the images and as a result, the surface of the object is covered with a layer of a fluorescent material, is then radiated with ultraviolet radiation, and the radiation emitted by the fluorescent material in the visible light is detected. | 06-09-2011 |
