The invention relates to a peening device for peening a component with a part to be peened and a part not to be peened. The peening device comprises a chamber with at least one opening located therein, wherein the opening is dimensioned in such a manner that the part not to be peened of the component can be guided there through, and a fixture for retaining the component which features a section which entirely covers the opening of the chamber when the part not to be peened is at least partially guided into said opening, and said section completely encloses the part not to be peened of the component between the adjacent region of the part to be peened of the component and the opening.

Conventional welding methods have the disadvantage of producing worse welded joints at the beginning of the process than in the later course of the method. The method in question uses an initializing plate on which the welding process is begun and then once a consistent quality can be achieved for the welded joint continues onto the points for repair.

Welding method and welding device

Process for preparing turbine blades or vanes for a subsequent treatment, for example the application of a coating and/or a material-removing operation, wherein the turbine blade or vane has an airfoil, which is delimited at at least one end by an endplate with peripheral surfaces, wherein at least one of the peripheral surfaces is at least partially covered prior to the treatment of the turbine blade or vane. In the process a covering strip is fitted onto at least one peripheral surface to form a plug connection.

A method includes coating a product with a metallic coating, in particular a high-temperature component product of a gas turbine, in a vacuum plant. An apparatus coats the product with a metallic coating in a vacuum plant, having a coating chamber and a postheat treatment chamber. Novel process control with regard to a temperature profile, in particular after the application of the metallic coating to the product and before the postheat treatment, involves the ensuring of a minimum temperature at all times, this minimum temperature being relatively higher than room temperature.

Method and device for coating a product

A method is directed toward decoating a parent body, provided with an anti-corrosion coating, of a turbine blade. An outer part of the anti-corrosion coating is removed abrasively by a water jet. An inner part of the anti-corrosion coating is then removed chemically. This combination permits efficient and cost-effective decoating of the turbine blade.

Method of decoating a turbine blade

The invention relates to a method for coating high-temperature components ( ) by means of plasma spraying. An infrared camera ( ) is used to determine the distribution of the thermal radiation ( ) of the component surface ( ), and to determine therefrom the temperature distribution ( ) in accordance with which a method parameter (p) is set in order to reach a threshold temperature (Ts). The invention also relates to a coating device for producing a coating ( ) while monitoring the surface temperature by means of an infrared camera ( ).
