This code contains welding requirements applicable to welding ground combat vehicles, other alloy structures and components. It is to be used in conjunction with appropriate complementary codes or specifications for materials design and construction. It is not intended to supplant codes developed for use in specialized fabrication, such as the ASME Boiler and Pressure Vessel Code, aerospace codes, or military specifications; it is appropriate for use in fabrication of ballistic and non-ballistic primary structures, supporting structures and appurtenances.
When conformance to the code is stipulated in contract documents, all provisions of this code shall be complied with, except for those provisions that contract documents specifically exempt.
The following is a summary of the code sections and appendices:
1. General Requirements — This section contains basic information on the scope and limitations of the code.
2. Design of Welded Connections — This section has been omitted. Responsibility for this section resides with the design agency.
3. Prequalification — This section contains the requirements for exempting a non-armor Welding Procedure Specification (WPS) from the qualification requirements of this code.
4. Qualification — This section contains the qualification requirements for non-armor WPSs and welding personnel (welders, welding operators and tack welders).
5. Fabrication — This section contains the requirements for the preparation, assembly and workmanship of welded steel structures.
6. Inspection — This section contains criteria for the qualifications and responsibilities of inspectors, acceptance criteria for production welds, and standard procedures for performing visual inspection and NDT (nondestructive testing) 7. Stud Welding — This section contains the requirement for the welding of studs.
Appendices
Appendix A — Code-Approved Base Materials. This appendix contains tables that cross-reference and group the base and filler material qualification requirements. Within the type/grade grouping, other materials not specifically listed, may also be used with this document with Engineering approval.
Appendix B — Welding of Armor Steel. This appendix contains the welding, testing, procedure qualification, and performance qualification requirements of armor steel.
Appendix C — Forms. This appendix contains applicable forms for procedure qualification, performance qualification, and armor welding data sheets.
Appendix D — Illustrations – Weld Positions, Test Specimens and Test Fixtures. This appendix contains illustrations displaying dimensional information related to test specimens and fixtures.
Appendix E — Prequalified Joint Details and Joint Preparations. This appendix contains the Prequalified WPS limitations.Intended Use: This document does not address the design of welded connections. The responsibility for the design and designation of weld criticality is a function of the appropriate design agency.
