Table 7-2. Grouping of Filler Materials (Welding) 1/ - Continued
NOTES:
1/ If filler material of similar chemistry and mechanical properties not listed under an A-group is to be used, it may be considered as a part of a group upon approval.
2/ Separate procedure qualification required (see 4-2.5 and 4-7.2); E6012 and E6013 qualify each other.
3/
See 4-7.2.b.
4/ Procedure qualification limited to 1T of test plate thickness for production groove welds. Overlay production use limited to 1/2T of qualification test plate (see 4-4.1.9). 5/ To be used with neutral flux when used with the submerged arc process. A neutral flux is defined as being one that does not readily oxidize the alloying elements or add significant alloy to the weld. 6/ Deposition technique using CoCr-A must yield a surface hardness of Rc35 minimum, unless a higher minimum hardness is required by the governing component specification/drawing, in which case the higher hardness requirement shall be met. 7/ Use in any position other than that specified for qualification testing in MIL-E-24403/2 and NAVSEA T9074-BC-GIB-010/0200 for this electrode shall require separate qualification and NAVSEA approval. 8/ Use of any shielding gas other than that specified for qualification testing in MIL-E-24403/2 and NAVSEA T9074-BC-GIB-010/0200 for this electrode shall require separate qualification and NAVSEA approval. 9/ The filler metal shall conform to all the quality conformance requirements for EN/RN625 specified in MIL-E-21562 but shall have a minimum tensile strength of 100 ksi, an elongation of 25 percent, and a chemical composition of ERNiCrMo-4 as specified in AWS A5.14/A5.14M. 10/ For other than clad welding applications involving these materials, procedure qualifications shall be submitted to NAVSEA for approval. Clad weld procedure qualifications shall be submitted for approval in accordance with 4-2.3.
11/ The interpass temperature for these materials shall not exceed 200 °F.
12/ These materials shall be used only with the gas tungsten arc, gas metal arc, and plasma arc welding processes, as applicable. 13/ The welding procedure and personal qualification requirements for MIL-120 and MIL-140 series filler materials shall be as approved by NAVSEA.
14/ With additional toughness and ferrite content requirements as imposed by the component specification.
15/ These electrodes are restricted in their use by the applicable fabrication document. 16/ The covered electrodes shall conform to all the quality conformance requirements of MIL-1N12 specified in MIL-E-22200/3 but with tensile properties and chemical composition of ENiCrMo-4 as specified in AWS A5.11/A5.11M. 17/ With additional melt control and composition, toughness, and other testing as approved by NAVSEA. Filler material specification requirements require NAVSEA approval prior to production welding. 18/ Alloy 625 type filler materials require separate welding performance qualification per table 7-8.
