Abstract
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.
