Abstract
A method of making an aerofoil blink comprising a plurality of aerofoil blades joined to a disc to extend radially outwardly therefrom is provided. The method includes the step of: (a) modelling a linear friction welding process in which a blade member is joined to the disc, the blade member having a stub for joining to the disc, wherein the modelling provides results which are indicative of the welding power at positions along the stub during the welding process; (b) identifying adaptations to the stub using the modelling results to compensate for differences in welding power along the stub during the welding process; (c) providing a blade member having a stub with the identified adaptations; and (d) joining the provided blade member to the disc by the linear friction welding process.
