Systems () and methods () for additively manufacturing or repairing a component from a base material (). The system may include a laser metal deposition (LMD) system () operably connected to a means for cooling () the base material during laser processing of additive materials deposited in a melt pool on the base material. The LMD system includes a laser energy source () configured to direct laser energy towards the base material to form the melt pool thereon and to processes the deposited additive materials to form layers on the base material upon solidification. The means for cooling may be configured to cool the base material to within a cooling temperature range during the LMD process, which results in, e.g., a cooling/freezing effect. This cooling effect shortens the solidification period during laser processing and allows for weld heat to be released from the base material.

A resonator ring for a combustor basket, in particular for a gas turbine power plant, which has at least one ring, wherein the ring or the rings has or have apertures, wherein insert plates are connected to the ring or the rings within the aperture. A method for producing a resonator ring, in which a ring or rings is or are produced from a first metal, then insert plates made of a, preferably cast, second material are connected to the ring or the rings, and individual resonator boxes are produced.

A system for manufacturing of a sintered wire and in-situ feeding to a laser wire welding system is presented. The system includes a pressure vessel connected to a powder feed system for delivering at least two powders to a powder mixing zone of the pressure vessel. The at least two powders are mixed via a rotating cone in the pressure vessel. After mixing, a heating device contained within the pressure vessel heats the mixture so that liquid phase sintering occurs and a sintered rod is created. The sintered wire is continuously fed to a laser metal deposition system for depositing a layer of additive material on a base material. A method of additively manufacturing or repairing a superalloy component is also presented.

Systems and methods for additively manufacturing or repairing a component from a base material. The system may include an inoculation source to direct inoculation materials and a laser metal deposition (LMD) system to direct laser energy during laser processing of additive materials deposited in a melt pool on the base material. The LMD system includes a laser energy source configured to direct laser energy towards the base material and inoculation materials to form the melt pool thereon and to process the deposited additive materials and inoculation materials to form layers on the base material upon solidification.

A method for joining a modular hot gas component by welding and high-temperature soldering. In order to optimally join high-temperature components, a first component is plugged into pins of a second component, a soldering material is placed between the two components, and the pins of the second component are welded to the first component.

A turbine blade for the rotor of a gas turbine, having a blade airfoil, which has a blade airfoil main body with a first material and a blade airfoil tip with a second material, the second material being more resistant to oxidation than the first material. The composition of the second material is graduated at least in subregions.

A method for producing a component by the successive solidification of individual layers of powdered, granular or liquid material by irradiation with laser radiation using a laser, each layer being divided into an inner region and an edge region with an edge region surface, and, for each layer, after irradiation with the laser, at least the edge region surface of the edge region of the layer being irradiated with an ultrashort pulse laser. An optical irradiation device produces a component by successive solidification of individual layers of powdered, granular or liquid material.

A method for generating, in layers, an application structure made of high heat resistant super alloys on a substrate is provided. A powdery construction material is melted by an energy beam at a working point, wherein the working point is guided across the substrate along a primary movement direction and thus swings transversely to the primary movement direction. The working point thereby swings from a first edge of a respective layer of the application structure to a second edge of the layer. In this way, a time interval passes between departure from a respective edge and a return to the respective edge directly following the departure, such that a melt bath on the respective edge solidifies into a paste-like zone during the time interval.

A method is provided for welding a substrate, in which an energy source and/or a material feed is or are moved in an oscillating motion over the surface of the substrate. The oscillating movement in a vertical and/or horizontal direction during welding results in smaller grains, which prevent the formation of fractures during welding.

Oscillating welding method

The use of a laser beam, which has an external and an internal laser beam area with different intensities allows a higher temperature gradient to be produced along the z direction, is provided.
