Method and arrangement for providing a stator or rotor component that is intended during operation to conduct a gas flow. A first wall part (14, 15) is placed with its one edge bearing against the flat side of a second wall part (9, 10), extending in the radial direction of the component, in such a way that the first wall part extends in the circumferential direction of the component. The edge of the first wall part is then laser-welded to the second wall part from an, in the circumferential direction, opposite side of the second wall part in relation to the first wall part in such a way that the joined-together portions of the wall parts form a T-shaped joint.

The invention claimed is: 1. A method for manufacturing a generally ring-shaped stator or rotor component which is intended during operation to conduct a gas flow, comprising: constructing a portion of said stator or rotor component by steps including 1) providing a curved first wall part having one edge bearing against a flat side of a second wall part that extends in a direction corresponding to an eventual radial direction of the component in such a way that the first wall part extends and curves in a direction corresponding to an eventual circumferential direction of the component and also extends in a direction corresponding to an eventual axial direction of the component; and 2) laser-welding the edge of the first wall part to the second wall part from an, in the circumferential direction, opposite side of the second wall part in relation to the first wall part in such a way that the joined-together portions of the wall parts form a T-shaped joint; wherein a sufficient number of stator or rotor component portions are so constructed and are mutually arranged so as to form the stator or rotor component, with the curved first wall parts of the stator or rotor components defining an axially extending, substantially annular flow-guiding surface that delimits a gas duct in said eventual radial direction. 2. The method as recited in claim 1, wherein the first wall part of said stator or rotor component portion abuts the flat side of the second wall part in generally perpendicular fashion. 3. The method as recited in claim 1, wherein the second wall part of said stator or rotor component portion is arranged such that it also extends in the direction corresponding to the eventual axial direction of the component. 4. The method as recited in claim 1, wherein the second wall part, extending in the direction corresponding to the eventual radial direction of the stator or rotor component, is arranged so as to circumferentially limit said gas duct in the direction corresponding to the eventual circumferential direction of the component. 5. The method as recited in claim 1, wherein the second wall part is arranged such that it has an essentially radial widening for guidance of the gas flow and/or transmission of load during operation of the component. 6. The method as recited in claim 1, wherein the first wall part is placed with a second edge, which is opposite to the first-named edge, bearing against the flat side of a further second wall part, which is arranged at a distance in the circumferential direction from the first-named second wall part, and is connected thereto. 7. The method as recited in claim 6, wherein the second edge of the first wall part is also laser-welded to this further second wall part from an, in the circumferential direction, opposite side of the second wall part in relation to the first wall part in such a way that the joined-together portions of the wall parts form a T-shaped joint. 8. The method as recited in claim 6, wherein the two second wall parts which are spaced apart in the circumferential direction constitute at least part of two different blades or stays for guidance of a gas flow and/or transmission of load. 9. The method as recited in claim 6, wherein the two second wall parts are formed by a single, substantially U-shaped element. 10. The method as recited in claim 9, wherein the first and second wall part are arranged between an, in the radial direction, inner and outer ring element and the U-shaped element, prior to the laser-welding of the wall parts, is arranged between the inner ring element and the outer ring element. 11. The method as recited in claim 1, wherein the first and second wall part are arranged between an, in the radial direction, inner and outer ring element. 12. The method as recited in claim 11, wherein the second wall part is connected to at least one of the ring elements by laser-welding from an, in the radial direction, opposite side of the ring element in relation to the second wall part in such a way that the joined-together portions form a T-shaped joint. 13. The method as recited in claim 1, wherein the stator or rotor component is intended for a gas turbine. 14. The method as recited in claim 1, wherein the stator or rotor component is intended for a jet engine.
