S9074-AQ-GIB-010/248 Rev 1
4-5.1.2 Radiographic (RT), Magnetic-Particle (MT), Liquid-Penetrant (PT), and Ultrasonic (UT) Inspection. RT, MT, PT, and UT shall be performed in accordance with NAVSEA T9074-AS-GIB-010/271. For PT of hardfacing, see figure 7-6, note 4. Backing bars, if employed, may be removed and weld reinforcement ground smooth prior to RT and UT inspection. 4-5.1.3 Acceptance Standards. Acceptance standards for RT, UT, MT, PT, and VT shall be based on the requirements of MIL-STD-2035, class I; for titanium welds, also see 4-5.1.1.1. 4-5.2 DESTRUCTIVE TESTS. Required specimen preparation, dimensions, mechanical testing, and test reports shall be in accordance with AWS B4.0. Test results shall be evaluated as outlined in 4-5.2.1 through 4-5.2.6. 4-5.2.1 Transverse Weld Tension Tests. For acceptance, transverse weld tension test specimens shall be as follows: a. Shall have a tensile strength not less than the minimum specified in the applicable base material specification. If materials of different minimum tensile strengths are used, the strength of the weaker material shall govern. b. Shall have a tensile strength not less than the specified minimum tensile strength of the weld metal in those cases where the fabrication documents allow the use of weld metal of lower room temperature strength than the base materials. For aluminum, where the governing specification does not require minimum tensile strength, filler metal minimum tensile strength shall be the value listed by S9074-A1-GIB-010/1628, except that 40,000 psi shall be used for alloy 5183 and strengths for A-24B shall be as approved by NAVSEA. c. In applying the criteria of 4-5.2.1.a and 4-5.2.1.b above for A5-A, A5-B, A5-C, and A5-D filler materials and HSLA-65, HY/HSLA-80, HY/HSLA-100, and HY-130 base materials, where the governing specification does not list a minimum tensile strength, the minimum tensile strength shall be that specified by S9074-A1-GIB-010/1628 . d. 6061-T6 and 6082-T6 aluminum shall have tensile strengths not less than 24 ksi and 28 ksi, respectively. Except for the case in 4-5.2.1.d, if the specimen breaks in the base material outside of the weld or fusion line, the test shall be accepted as meeting the requirements, provided the strength is not more than 5 percent below the requirements specified herein. For the case in 4-5.2.1.d, no reduction in the minimum specified strength is permitted. For castings, see table 7-7, footnote 1. 4-5.2.2 All-Weld Metal Tension Tests. For acceptance, all-weld metal tension test specimens shall meet the minimum specified mechanical properties of the applicable filler material specification. 4-5.2.2.1 Titanium Specimens. Where properties are not specified in the filler material specifications, titanium weld specimens shall meet the minimum tensile and yield strength of the base material, and elongation and reduction in area shall be reported for information. 4-5.2.3 Guided Bend Tests. When guided bend tests are specified in table 7-7, joints of similar materials shall be tested by transverse bends, and joints of dissimilar materials shall be tested by longitudinal or transverse bends. For materials with 20 percent or less minimum elongation requirements, elongation for determining bend radius shall be selected based on the base metal or filler metal specification minimum elongation requirement, whichever is lower; where base material elongations are different, the lower minimum elongation shall govern. For welds and materials with elongation requirements exceeding 20 percent elongation, bend testing at 20 percent elongation is required. 4-5.2.3.1 Criteria for Acceptance. For acceptance, the guided bend specimen after bending shall have no cracks or other open defects greater than 1/8 inch (except weld cladding). The maximum open defect dimension in the cladding of corrosion-resistant weld clad bend tests shall be 1/16 inch. Cracks occurring on the corners of the specimen during testing shall not be considered unless there is definite evidence that they result from slag inclusions or other internal defects. Openings in the base metal outside the weld deposit and HAZ shall not be cause for rejection.
