Procedure

    1. SUBTASK 72-50-23-110-103 Clean the Worn Surfaces before Welding

      1. Clean the surfaces to be welded.

      1. Use silicon carbide rag or equivalent.

    2. SUBTASK 72-50-23-220-122 Examine the Surfaces to be Welded

      1. Do the test for cracks locally.

      1. Refer to SPM TASK 70-23-05-230-501.

        No cracks permitted.

    3. SUBTASK 72-50-23-110-104 Clean the Stage 5 turbine Airseal Segment

      1. Clean the segment.

      1. Refer to SPM TASK 70-11-03-200-503.

    4. SUBTASK 72-50-23-310-071 Weld Repair the Worn Surfaces

      1. Build up surfaces. Use manual tungsten inert gas weld technique.

      1. Refer to Figure and SPM TASK 70-31-13-310-501.

        Make sure that there is sufficient material to do last machining.

        To prevent honeycomb braze damage, several weld passes should be made.

        Prevent too much temperature build-up.

    5. SUBTASK 72-50-23-220-123 Examine the Welded Surfaces for Cracks

      1. Do the test for cracks on welded areas.

      1. Refer to SPM TASK 70-23-05-230-501.

        No cracks permitted.

    6. SUBTASK 72-50-23-320-054 Machine the Welded Areas

      1. Machine the repaired areas.

      2. Remove all surplus weld to original contours.

      1. Welded areas must be blended into adjacent surfaces.

        The surface texture of the blended surface must be equal to or better than that of the adjacent area.

    7. SUBTASK 72-50-23-220-124 Examine the Machined Dimensions

      1. Dimensionally examine the repaired areas.

      1. For finish dimensions refer to Figure.

      2. Do the test for cracks on the repaired areas.

      1. Refer to SPM TASK 70-23-05-230-501.

        No cracks permitted.

      3. Clean the stage 5 turbine airseal segment.

      1. Refer to SPM TASK 70-11-03-200-502.
