1. A method of friction welding a first component to a second component, the method comprising the steps of:
rotating the first component relative to the second component about a rotation axis; and
bringing the first component into contact with the second component;
wherein, while the first component and the second component are in contact, a first average force is applied during a first stage of the friction welding process and a second average force is applied during a second stage of the friction welding process, wherein force applied during the second stage changes at a constant rate until the friction welding process is complete;
the second average force is different from the first force; and
the rotation speed of the first component relative to the second component decreases during the first stage.
