Machining of the weld joints shall be per DWG 803-2145807 (see excerpt above), with the following exceptions:

• To prevent weld burn-thru, as well as excessively thin welds in the way of GRP end preps, the backing strip thickness shall be 0.188” +0.000/-0.005”.

• To improve weld shrinkage, the 50° bevel angle in the weld joint detail (Detail 61-B) shall be changed to 60°.

• To ensure watertight integrity at the sleeve ends, the backing strip widths will be increased for the first 6” under the ends of the finished sleeve so as to reduce the fit-up gap to 0.019” +/- 0.003”, which will result in a nominal shrink fit at the sleeve ends of 0.012”. For the remainder of the joint between the 6” ends, the fit-up gap shall be 0.022” +/-0.003”, which will result in a nominal shrink fit of 0.014”. The transition in backing strip width shall have a generous corner break so as not to create a sharp step.

Measure and record the widths of the backing strips (Wstrip) and that of the respective slots (Wslot) prior to splitting the sleeve into halves.

During welded installation of the sleeves, strain gages shall be installed to monitor the stress due to weld shrinkage as follows:

• A welding procedure prepared by a welding engineer and approved by NAVSEA is required.

• Strain gages shall be located along the weld joints (both sides) and 90° from the weld joints along the length of the sleeve. The distance between the gages and the weld joints shall be sufficient to prevent gage damage, de-bonding, or false readings.

• All strain gages will measure uniaxial strain around the circumference of the sleeve, so as to indicate the measured shrink fit.

• The prior joint modifications require placement of strain gages within 3” of the sleeve ends and additional gages in between shall coincide with the dimensional measurement stations along the length of the sleeve to monitor the stress in areas of design and modified fit-up.

• The sleeves shall be accurately aligned and securely clamped to the shaft and appropriately grounded prior to welding. In no case shall the sleeve be welded to the shaft.

• Peening of welds shall only be accomplished as required to remove excessive stress, while optimizing residual stress within the allowable limits. Repair activities are cautioned against premature peening of welds in an effort to limit the in-process stress below the 16 ksi limit, as this typically leads to insufficient shrink fit in the final condition. Based on a modulus of elasticity of 21 x 106 psi, the threshold strain limit after final welding would be 762 x 10-6 in/in.

• Every weld layer will be subject to a liquid dye penetrant (PT) inspection with Class 2 acceptance criteria per MIL-STD-2035A(SH) in lieu of the RT requirements for M-1 Category A in S9074-AR- GIB-010/278. The final PT shall also use Class 2 acceptance criteria.

• After welding there shall be no gap between the sleeve groove and backing strip. If gaps remain, or if any of the strain gages indicate a shrink fit of less than 0.012”, a completed copy of this document shall be submitted for engineering evaluation prior to machining the sleeve.

Measure and record the final strain [e] values indicated by the strain gages.

e

After final welding, but prior to removing the runoff portion of the backing strips, measure and record the final widths of the backing strip by measuring the protruding portion of the backing strips immediately adjacent to the sleeve end at each end of each weld joint using dial calipers.

Prior to machining the sleeve, measure and record any gaps remaining after final installation, where GAPfinal for a particular sleeve end is the sum total of combined gaps remaining in both joints at that end, as determined by inspection with wire, cut-down feeler gages, etc.

GAPfinal

Upon completion of welding, and to ensure watertight integrity, the ends of the weld joints shall be ground after final machining to remove metal burrs that may have been forced into gaps remaining around the ends of the backing strips. Grinding is to be a minimum of 0.03” deep and is to include the outline of the backing strip to the maximum extent possible without damaging the shaft surface.

Incidental damage to the shaft must be evaluated for acceptability, faired smooth, and be subject to either MT or PT per NAVSEA Technical Publication T9074-AS-GIB-010/271.

Following grinding, repeat measurements and record any gaps remaining after final machining, where GAPmachined for a particular sleeve end is the sum total of combined gaps remaining in both joints at that end, as determined by inspection with wire, cut-down feeler gages, etc.

Following grinding, the ends of the weld joints and the entire periphery of the sleeve ends and backing strip ends shall be sealed with a wicking grade thread sealant (Loctite 290 or equivalent).

NOTE: Measurement stations B and D are not required for sleeves less than 36” in length.

NOTE: At least 24 hours before taking measurements, place the sleeve in close proximity to the shaft to ensure that both are at the same temperature and that both shaft and sleeve are between 60°F - 80°F.

2.4.2 CHECKPOINT (SP-1 Cleanliness Prior to Preparation Inspection):

2.4.2.1 Verify that a freshwater wash down was performed as specified in Section 5.2.

Sign Table 3 after completion of fresh water wash down.

Perform a visual inspection to verify all surfaces to be blasted are free of hydrocarbons, and other contaminants such as sea salts, loose rust, mud, and marine growth, which could become imbedded in the surface to be prepared.

2.4.2.3 The SP-1 surface condition shall be met prior to abrasive blasting or mechanical surface preparation. Sign Table 3 when pre-surface preparation inspection is satisfactory.

2.4.2.4 Have the Abrasive Blasting Prerequisite List shown on Appendix A completed and signed by the appropriate departments.

2.4.3 Where doubt exists as to the adequacy of surface cleanliness prior to surface preparation, inspect the surface using a UV light (approx. 60 A) to detect hydrocarbons on the surface. The ultraviolet light will not allow the proper detection of hydrocarbons on the surface if the surface being inspected is exposed to day or artificial light. For proper UV light hydrocarbon detection, lights must be off for interior spaces, and the inspection must be conducted during darkness for surfaces exposed to sunlight. Take appropriate safety measures to prevent worker hazards in the darkened space. When hydrocarbons are present, the hydrocarbons will fluoresce as bright green, lime green, or blue/violet on the surface.

CAUTION

UV lights that contain mercury are prohibited from use in mercury exclusion areas.

2.4.4 To remove detected contaminants or hydrocarbons, perform a solvent wipe using clean lint free rags wetted with IPA or PF-145HP on affected areas to achieve a SP-1 surface condition.

2.4.5 If contaminants or hydrocarbons are detected on the surface after attempting to solvent spot repair, de-grease the surface again.

3. SURFACE PREPARATION:

3.1 Monitor environmental conditions during surface preparation operations to ensure they meet the requirements in paragraphs herein. All blasted surfaces shall meet the surface condition of "near white metal". "Near white metal" is defined as a surface from which all oil, grease, dirt, mill scale, rust, paint, hull fairing compound, and other foreign material have been removed except for very slight streaks or discolorations. The blasted steel surface shall have an appearance similar to or better than SNAME Bulletin #4-9, Figure 12, or Society for Protective Coatings: SSPC, surface preparation standard SSPC SP-10.

3.2 The average surface profile shall be 2.5 to 3.5 mils, with no profiles less than 2 mils or greater than 4 mils as measured using a Testex Inc. Replica Tape/Dial Indicator Profile measuring system (ASTM D4417, method C).

3.3 Blasted surfaces shall be blown down and/or vacuumed to remove all blasting residue prior to painting. Only dry, oil free compressed air shall be used for blasting and blowing down. Spent abrasive and paint particles shall be disposed of according to the latest waste disposal regulations of the federal, state and local governments.

3.4 CHECKPOINT (Surface Preparation):

3.4.1 Check the surface for compliance with the applicable surface preparation standard (SP-10). The record shall show the extent of the inspection and detailed results. Visual aids provided in Ref. 2.d or 2.e may be used to ensure quality standards are met.

3.4.2 Check and record the surface profile of abrasive blasted surfaces using TESTEX PRESS-0-FILM replica tape (X-course).

3.4.3 Perform surface cleanliness tests (tape test) in accordance with ISO 8502-3.

4. PAINTING REQUIREMENTS:

4.1 CHECKPOINT (Shelf life): Verify shelf life of material has not expired. Recording not required.

4.2 Verify that application of the first spray coat is complete within 24 hours of surface preparation. If more than 24 hours has passed, request QA to re-inspect unpainted areas to verify that the surface preparation is still satisfactory.

4.3 Apply the Sherwin Williams Nova plate UHS Primer to the prepared surfaces at 14-18 mils DFT to the shaft.

4.4 The SYSTEM DFTs shown above are target thicknesses. The overall average of the dry film thickness measurements shall not be less than the low end of the range for the System DFT shown above and may be up to 1.25 times the maximum thickness shown for the range.

4.5 Do not take dry film thickness measurements on runs, drips, sags or puddles, or (when a stripe coat is applied) directly on striped welds, striped edges, etc.

Note that depending on configuration, a 'spray-stripe' application may extend onto flat surfaces further than a typical brush applied stripe coat. In this case the stripe coat thickness may be captured while measuring total system DFT.

During welded installation of the sleeves, strain gages shall be installed to monitor the stress due to

• A welding procedure prepared by a welding engineer and approved by NAVSEA is required.

• Strain gages shall be located along the weld joints (both sides) and 90° from the weld joints along the length of the sleeve. The distance between the gages and the weld joints shall be sufficient to prevent gage damage, de-bonding, or false readings.

• All strain gages will measure uniaxial strain around the circumference of the sleeve, so as to indicate the measured shrink fit.

• The prior joint modifications require placement of strain gages within 3” of the sleeve ends and additional gages in between shall coincide with the dimensional measurement stations along the length of the sleeve to monitor the stress in areas of design and modified fit-up.

• The sleeves shall be accurately aligned and securely clamped to the shaft and appropriately grounded prior to welding. In no case shall the sleeve be welded to the shaft.

• Peening of welds shall only be accomplished as required to remove excessive stress, while optimizing residual stress within the allowable limits. Repair activities are cautioned against premature peening of welds in an effort to limit the in-process stress below the 16 ksi limit, as this typically leads to insufficient shrink fit in the final condition. Based on a modulus of elasticity of 21 x 106 psi, the threshold strain limit after final welding would be 762 x 10-6 in/in.

• Every weld layer will be subject to a liquid dye penetrant (PT) inspection with Class 2 acceptance criteria per MIL-STD-2035A(SH) in lieu of the RT requirements for M-1 Category A in S9074-AR- GIB-010/278. The final PT shall also use Class 2 acceptance criteria.

• After welding there shall be no gap between the sleeve groove and backing strip. If gaps

After final welding, but prior to removing the runoff portion of the backing strips, measure and record the final widths of the backing strip by measuring the protruding portion of the backing strips immediately adjacent to the sleeve end at each end of each weld joint using dial calipers.

AFT End FWD End

Prior to machining the sleeve, measure and record any gaps remaining after final installation, where GAPfinal for a particular sleeve end is the sum total of combined gaps remaining in both joints at that end, as determined by inspection with wire, cut-down feeler gages, etc.

Upon completion of welding, and to ensure watertight integrity, the ends of the weld joints shall be ground after final machining to remove metal burrs that may have been forced into gaps remaining around the ends of the backing strips.

Grinding is to be a minimum of 0.03” deep and is to include the outline of the backing strip to the maximum extent possible without damaging the shaft surface. Incidental damage to the shaft must be evaluated for acceptability, faired smooth, and be subject to either MT or PT per NAVSEA Technical Publication T9074-AS-GIB-010/271.

Following grinding, repeat measurements and record any gaps remaining after final machining, where GAPmachined for a particular sleeve end is the sum total of combined gaps remaining in both joints at that end, as determined by inspection with wire, cut-down feeler gages, etc.

Following grinding, the ends of the weld joints and the entire periphery of the sleeve ends and backing strip ends shall be sealed with a wicking grade thread sealant (Loctite 290 or equivalent).
