Abstract:
1. A method for manufacturing a stator component that is intended for a jet engine and intended in operation to guide a gas flow and to transfer loads, comprising constructing the component of at least two sections in the direction of its circumference, casting the sections in separate pieces, positioning the at least two sections adjacent to each other, joining the at least two sections together by welding, casting each section of the at least two sections in such a shape that a first, radially and axially extending wall element and a second, radially and axially extending wall element are arranged at a distance from each other, an inner plate and an outer plate are disposed at opposite ends of and substantially perpendicular to the first and second wall elements, the first and second walls elements defining between them a gas duct defining a flow path extending in an axial direction of the component, and joining two wall elements, one from each of two adjacent sections, to each other to form together a radially and axially extending strut, which is closed for an incoming axial flow so that there will be no axial flow path between the joined wall elements.
