Material of component

The HP compressor rotor blades - stage 3, are made from titanium alloy.

General

This repair must only be done when the instruction to do so is given in 72-41-15 Inspection/Check.

This repair restores the HP compressor rotor blade, stage 3 tip length by welding.

The practices and processes referred to in the procedure by the TASK/SUBTASK numbers are in the SPM.

This is a source demonstrated repair which can only be done by approved vendors.

To keep the HP compressor efficiency, rotor blades are repaired as near to the new blade condition as possible.

Rotor blades must be repaired as soon as damage or wear is monitored, to get back HP compressor efficiency and extend the rotor blade life.

This repair can be done again to the welded rotor blades if:

- The minimum airfoil dimensions are as given in 72-41-15 Inspection.

- The airfoil surface has been polished up to two times, refer to VRS6150, TASK 72-41-15-300-040 (REPAIR-040).

Discard the blades if, during the weld procedure, arcing has occurred on any part of the blades.

Price and Availability
