Procedure

    1. SUBTASK 72-50-23-110-165 Clean the Worn Surfaces before Welding

      1. Clean the areas to be welded.

      1. Use silicon carbide rag or equivalent.

    2. SUBTASK 72-50-23-110-166 Clean the Stage 3 Shroud Seal Segment

      1. Aqueous cleaning.

      1. Refer to the SPM TASK 70-11-03-300-503.

    3. SUBTASK 72-50-23-310-098 Weld Repair the Worn Surfaces

    1. Refer to Figure.

      2. Gas tungsten arc weld the worn surfaces.

      1. Refer to the SPM TASK 70-31-13-310-501. Make sure that there is sufficient material to do last machining.

        Use CoMat 03-287 WELDING FILLER WIRE. To prevent honeycomb braze damage, several weld passes should be made. Prevent too much temperature build-up.

    4. SUBTASK 72-50-23-320-092 Dress the Welded Areas

      CAUTION

      DO NOT OVERHEAT THE AREAS WHICH ARE DRESSED.

    1. Refer to Figure.

      2. Dress the welds.

      1. Welded areas must be equal to the original contours and must be flush with the adjacent surfaces.

        Use hand held grinder.

      3. Bend the shroud seal segment back to shape if required.

      1. Use cold work.

        Make sure that the shroud seal segment aligns with the IAE 3M14212 Grinding/turning fixture 1 off.

    5. SUBTASK 72-50-23-230-110 Examine the Welded Areas for Cracks

      1. Do the test for cracks.

      1. Refer to the SPM TASK 70-23-05-230-501. Use medium sensitivity level.

        No cracks are permitted.

    6. SUBTASK 72-50-23-220-178 Examine the Machined Areas

      1. Examine dimensionally.

      1. Refer to Figure.

    7. SUBTASK 72-50-23-110-167 Clean the Stage 3 Shroud Seal Segment

      1. Aqueous cleaning.

      1. Refer to the SPM TASK 70-11-03-300-503.
