Abstract: A method for assembling a wind turbine blade is disclosed. The method includes providing a root end element 70 of the wind turbine blade 10, providing a tip end element 72 of the wind turbine blade 10, and inserting one or more alignment members 82 at pre-defined positions in at least one of the root end elements 70 and the tip end element 72. The one or more alignment members 82 is of a pre-defined shape. The method further includes aligning the one or more members 82 with a receiver portion of at least one of the root end elements 70 and the tip end element 72 in which the one or more alignment members 82 is not inserted, along a joining portion. Then, joining the root end element 70 and the tip end element 72 wherein, during joining, the one or more alignment members 82 align along a longitudinal axis of at least one of the root end elements 70 and the tip end element 72.
