Procedure

    1. SUBTASK 72-50-32-350-113 General Instructions for the Rework of the Stage 3 LP Turbine Blades

      1. Inspect turbine blade.

      1. Refer to TASK 72-50-32-200-000 (INSPECTION/CHECK-000).

    2. Repair the blade if applicable.

    2. SUBTASK 72-50-32-350-114 Prepare the Turbine Blade for Build Up Welding

      1. Locally remove the aluminide coating.

      1. Locally remove aluminide coating from shroud surface.

        Refer to Figure.

        Install the blade into IAE 3M14382 Welding fixture welding fixture 1 off.

    3. SUBTASK 72-50-32-310-060 Weld the Stage 3 Turbine Blade

      1. Build up weld the shingling stop.

      1. Refer to the SPM TASK 70-31-08-310-501.

        Use CoMat 03-283 COATING ALLOY to the dimensions given in Figure.

        Electrical contact in area CZ is permitted.

        No burring, no selective attack are permitted.

    4. SUBTASK 72-50-32-220-215 Dimensionally Inspect the Reworked Stage 3 Turbine Blades

      1. Check dimensions.

      1. Refer to requirements given in Figure.

    5. SUBTASK 72-50-32-220-216 Do a Hardness Check on the Weld Location

      1. Do a hardness check on the weld location.

      1. Minimum hardness 40 HRC.

    6. SUBTASK 72-50-32-230-116 Do a Crack Test on the Weld Location

      1. Do a crack test.

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

        Discontinuities up to 0.016in. (0.4 mm) are permitted.

    7. SUBTASK 72-50-32-850-052 Reidentify the Stage 3 Turbine Blade with the New Part Number

      1. Reidentify with new part number. Use roller stamp method or vibropeen method.

      1. PART NUMBER BEFORE - 3A0883.

        NEW PART NUMBER - 3A2053.

        Refer to the SPM TASK 70-09-00-400-501.

        Refer to Fig. 72-50-32-990-130.
