Abstract: A method for manufacturing a blade shell part of a wind turbine blade includes providing a mould for manufacturing a blade shell part of the wind turbine blade. The mould has a first moulding side with a first moulding surface that defines an outer shape of the blade shell part. The method comprises providing a blade shell part on the first moulding surface and providing a support element and attaching the support element to a fastening section of the blade shell part. Attaching the support element includes applying adhesive between the support element and the fastening part. The method also includes providing an air heating assembly having a cover extending in a longitudinal direction between a first cover end and a second cover end and extending in a transverse direction between a primary cover end and a secondary cover end, the cover defining a cavity.
