1. A method for manufacturing a wind turbine blade, comprising:
arranging a joining portion comprising a fiber lay-up inside adjacent blade sections,
covering the joining portion and the adjacent blade sections at least partially with a vacuum bag, and
applying vacuum to a space covered by the vacuum bag, infusing at least the fiber lay-up with a resin, and curing the resin to obtain a cured joining portion joining the blade sections inside such that the cured joining portion joins the adjacent blade sections on their inside surfaces,
wherein the joining portion is provided on a mandrel, and the joining portion is arranged inside the adjacent blade sections by arranging the mandrel with the joining portion inside the adjacent blade sections, and
wherein the vacuum bag is prepacked with the joining portion on the mandrel.
