Abstract

A method of manufacturing a wind turbine blade for a horizontal axis wind turbine (2), and mounting it to the pitch bearing of a hub of a wind turbine is described. The method comprises the steps of: manufacturing (402) a first wind turbine blade shell part; manufacturing (404) a second wind turbine blade shell part; assembling (406) at least the first wind turbine blade shell part and the second wind turbine blade shell part to form at least part of a shell body of the wind turbine blade, wherein the wind turbine blade extends between a root end and a tip end, and wherein the first wind turbine blade shell part and the second wind turbine blade shell part are at least adhered to each other along a first bond line that extends to the root end of the wind turbine blade; providing (408) a ring-shaped root end flange, which is configured to be connected to the root end of the shell body, and which is configured with a bond line marker, preferably on an inner circumference of the ring-shaped root end flange, and further configured with a pitch-angle marker; attaching (410) the ring-shaped root end flange to a root end face of the shell body, such that the ring-shaped root end flange covers the first bond line, and the bond line marker is aligned with the first bond line; and mounting (412) the wind turbine blade including the ring-shaped root end flange to the pitch bearing of the hub of the wind turbine, such that the pitch-angle marker is aligned with a zero-pitch position for the pitch bearing.
