Consumable collar for linear friction welding of blade replacement for damaged integrally blades rotors

A method of repairing an integrally bladed rotor (20) includes the steps of placing a support collar (29) around at least leading and trailing edge portions (41,43) of the blade stub (24), and performing linear friction welding to add a replacement airfoil (60) to the blade stub (24). The linear fri...

Zusammenfassung:	A method of repairing an integrally bladed rotor (20) includes the steps of placing a support collar (29) around at least leading and trailing edge portions (41,43) of the blade stub (24), and performing linear friction welding to add a replacement airfoil (60) to the blade stub (24). The linear friction welding is generally along a direction between the leading and trailing edges (41,43). In addition, the support collar leading and trailing edge portions are connected together.
