A machine component including a base body produced from a base material is provided. The base body is equipped in a partial region of the surface thereof with a plating made of an application material having a greater hardness and/or viscosity as compared to the base material. The plating is foamed by a number of plating elements that are applied to the base body in the longitudinal direction thereof in a tilted manner relative to the main flow direction of a hot gas flowing through the base body.

A method for producing a part from ductile iron, including the steps of designing the part in such a way that the part is composed of a plurality of part components, producing the part components from ductile iron, providing the part components in pairs, depositing buffer material onto the rim edge of the first part component and onto the rim edge of the second part component by means of deposition welding, laying the second part component with the rim section thereof on the rim section of the first part component so that the rim edges lie against each other with the buffer materials thereof, and welding the rim sections, wherein the buffer material is selected in such a way that a structure change in the ductile iron material of the part components is prevented when the rim sections are welded.

Method for the welding production of a large-dimensioned part from ductile iron by using laser-deposition-welded buffer materials and electric welding

A burner assembly is provided. The burner assembly includes a support housing with a supply manifold, the supply manifold includes a fuel passage system, and fuel nozzles extending from the supply manifold and being supplied with fuel through the fuel passage system of the supply manifold. The supply manifold is sandwiched using at least two subparts.

The repair of cracks according to the state of the art comprises the fact that defects located on the inside must be worked outward in order to be able to be welded closed. The method according to the invention proposes not to work out cracks located on the inside, but to melt the crack located on the inside utilizing a flux agent.

Welded repair of defects lying on the inside of components

A machine component with a base body made of a base material, a part of the surface of which has been equipped with cladding material having a hardness greater in comparison to the base material. The cladding material is segmented and made up of a number of cladding segments that are spaced apart on the machine component. Each cladding segment may be disposed within a respective recess on the surface of the base body forming strips of the base body and material, and each such strip is disposed between consecutive segments forming a continuous surface.
