Zusammenfassung:	A method for retrofitting a wind turbine blade with a replacement blade tip segment includes producing a replacement blade tip segment with an internal beam receiver section, and producing a beam structure. The existing blade tip segment is cut away from the wind turbine blade, wherein the cut defines a chord-wise joint line at the remaining blade root segment of the wind turbine blade. The beam structure is fixed into spar structure of the blade root segment. The replacement blade tip segment is aligned and connected with the blade root segment in a span-wise direction so that the beam structure moves into the beam receiver section. A finish surface can be provided to the blade shell components of the blade root segment and the replacement tip segment at the joint line.
