A device is provided for heating a turbine blade or vane in that a heating coil is arranged in a particular manner to obtain a temperature gradient in a component. A process for welding a turbine blade or vane is also provided. | 01-06-2011 |
| 20110020127 | Component Comprising Overlapping Weld Seams and Method for the Production Thereof - A turbine blade or vane with a platform and two overlapping weld seams, each weld seam having a width, is provided. An overlapping region of the two weld seams is 40% to 60% of the width of one weld seam. The weld seams run parallel or perpendicularly to the platform of the turbine blade or vane. Further, a method for welding a turbine blade or vane is provided. | 01-27-2011 |
| 20110056919 | Method for Fusing Curved Surfaces, and a Device - A method for fusing a curved surface of a substrate is provided. An energy beam with an energy source and a curved surface of a substrate are provided. The energy beam and/or the substrate are moved toward one another in order to fuse the curved surface and an orientation of the energy beam in relation to the curved surface is varied during the fusing of the curved surface. | 03-10-2011 |
| 20110062120 | Device for welding using a process chamber and welding method - A device and a method for welding a component are provided. The component is arranged and welded in a chamber. A welding appliance is provided, the welding appliance being arranged outside the chamber. | 03-17-2011 |
| 20110073636 | Method and device for welding workpieces made of high-temperature resistant super Alloys - A method of welding workpieces of high-temperature superalloys is provided. Welding filler is applied in a plurality of layers to a surface of the workpiece via a heat input zone and a supply zone for supplying the welding filler into the heat input zone. The heat input zone and the supply zone on the one hand and the workpiece surface on the other hand are moved in relation to one another. A polycrystalline weld seam is generated by remelting a previously applied layer of the plurality of layers. Welding parameters are chosen such that a cooling rate during a solidifying of the material is at least 8000 Kelvins per second. Further, a welding apparatus for carrying out such a method is provided. | 03-31-2011 |
| 20110089150 | Method and Apparatus for Welding Workpieces of High-Temperature Superalloys - A welding apparatus for welding workpieces of high-temperature superalloys is provided. The welding apparatus includes a heat source for producing a heat input zone on the workpiece surface, a supplying device for supplying welding filler into the heat input zone and a transporting device for producing a relative movement between the heat source and the supplying device on the one hand and the workpiece surface on the other hand. The welding apparatus further includes a control unit with a control program, which carries out the relative movement in such a way that the welding power and the diameter of the heat input zone are set such that the cooling rate during the solidifying of the material is at least 8000 Kelvins per second. | 04-21-2011 |
| 20110100964 | WELDING PROCESS WITH A CONTROLLED TEMPERATURE PROFILE AND A DEVICE THEREFOR - A welding method in which the power is controlled in accordance with the temperature of the welding point is provided. The temperature of the welding point is lowered in a controlled manner at the end of the method and the temperature of this welding point is measured by a temperature measuring appliance. | 05-05-2011 |
| 20110111248 | Component Having Weld Seam and Method for Producing a Weld Seam - During welding, frequently cracks develop at the end of the weld seam. A method is provided in which the power is reduced at the end of the weld seam, reducing the development of cracks. For the method, a welding appliance is used wherein the welding appliance may be a laser. | 05-12-2011 |
