NOTES:
1/ The mechanical properties of test weldments for cast materials shall meet the minimum requirements of the applicable base material specification, except when the base material is shown, by actual testing, to have lower values. In this case, these lower values may be used to evaluate and accept the mechanical property test results of the weldment, provided: (a) The actual tensile properties of the weldment are equal to at least 90 percent of the values in the applicable base material specification. (b) The bend angle of the test weldment specimen is equal to or greater than that attained with the base metal test specimen. 2/ Charpy V-notch (CVN) impact tests shall be performed under any of the following conditions: (a) For production welding of material 1/2 inch or greater in thickness when both the base metal specification and the filler metal specification have impact requirements (except when the production application is for weld cladding). (b) For production welding of material 1/2 inch or greater in thickness in bimetallic joints where both base metals and the filler metal specifications have impact requirements. Where qualification was performed on base material without specified toughness requirements and cross-qualification is permitted for materials having toughness requirements, welding of materials with toughness requirements shall be limited to 1/2 inch or less in thickness. (c) When specified by the fabrication document or governing specification. (d) For production welding of S-53A materials 1/2 inch or greater in thickness, unless otherwise approved by NAVSEA. Toughness test, test method, temperature, and acceptance criteria shall be as approved by NAVSEA. 3/ See 4-4.6 and 4-4.8.1. 4/ When required for the testing of specimens taken from thick test assemblies, the reduced section tensile specimens and the side bend specimens shall be cut into multiple specimens as permitted by AWS B4.0.
