Abstract: The present invention relates to methods and devices for post mould processing of a composite structure, wherein the composite structure extends along a longitudinal direction and comprising a main composite part, and a flange section extending around a perimeter of the main composite part. The flange section comprises an upper surface having a first mating part with a specific shape in a cross-sectional plane perpendicular to the longitudinal direction, the first mating part being located at a fixed position relative to the main composite part. The method may comprise attaching a guiding device to the outer surface of the composite structure and inspecting and/or processing the surface area with a tool fitted to the guiding device.

Abstract: A method for assembling a component, such as a wind turbine blade, includes providing a first element of the component and providing a second element of the component. An alignment member is inserted at a predefined position in one of the first or second elements, the alignment member having a predefined shape. The alignment member is positioned within a receiver portion of the other of the first or second elements along a joining portion, and the first and second elements are then joined. During the joining process, the alignment member aligns along a longitudinal axis of at least one of the first or second elements.

Abstract: A method of manufacturing a shell (36 and 38) of a wind turbine blade (10) is disclosed. The method comprises providing a mould (9) having a marker (11) at pre-determined locations. One or more layers of fiber fabrics are provided on surface of the mould (9) to form a shell half structure (36 and 38). Resin is infused through the one or more layers of fiber fabrics and subsequently cured to obtain the shell half structure (36 and 38). A reference portion (19) is marked on the shell half structure (36 and 38) to assemble one or more components on the shell half structure (36 and 38), by detecting a location of the marker (11) in the mould (9) by a detection device (13). The above method facilitates accurate positioning of component such as shear webs (7).
