Abstract: Disclosed is a wind turbine blade extending from a root end to a tip end, the wind turbine blade comprising a root region, and an airfoil region comprising the tip, a pressure side, a suction side and a chord extending between a leading edge and a trailing edge. The wind turbine blade comprises a leading edge protection element at the leading edge of the wind turbine blade. The leading edge protection element extends in a longitudinal direction between an outboard end and an inboard end and comprises a first section extending from the outboard end to a first section position, wherein the first section is made of a first erosion protection material having a first erosion resistance, and a second section extending from the first section position to a second section position, wherein the second section is made of a second erosion protective material having a second erosion resistance. The first erosion resistance is larger than the second erosion resistance.

Abstract: A method for assembling an integrated wind turbine blade shell, comprising:
attaching and distributing cleats onto the first wind turbine shell part at a distance from the first edge of a first wind turbine blade part, wherein a ledge surface and a rail of each cleat define, together with the interior surface, a ledge for supporting a glue flange;
securing a clamp tool to the anchor of each cleat;
resting the separately manufactured glue flange on the ledge surface of each cleat;
closing the first and second wind turbine blade shell parts;
actuate the clamp tools to clamp the glue flange between the clamp head of each clamp tool and interior surface; and
detaching and removing the clamp tools from the cleats.-
