19207-12472301 Revision A Page 3 of 123 Downloaded from https://www.everyspec.com Preface Format This document follows the AWS format, and is based on the current practice in the manufacture of ground combat vehicles. Therefore, the section that normally would be included to establish design standards has been eliminated from this code. This follows the practice within this industry of having design performed by structural design engineers using the latest in finite element analysis techniques. used in conjunction with Section 6 which establishes basic quality procedures.
Sections 1 through 5, excluding the nonexistent Section 2, establish the general workmanship and technique requirements for all aluminum welding. It also establishes the qualification of procedures and of welders. These sections produce the framework for good welding performance in any facility fabricating components for our country’s defense. They must be followed for the establishment of an acceptable facility with welders capable of performing the welding needed for this fabrication. This code has been divided into 9 sections (sections 1 through 10, with section 2, normally applied to design, eliminated) that can be grouped into the following areas related to welding manufacture:
Specification Cross Reference • General welding procedural requirements for the qualification of welding processes and weld joint geometries. A table is included on page 4 to provide a cross- reference between this code and military standards and specifications (active and cancelled). • Specific requirements for qualifying welders for various welding processes. Revisions • Specific requirements for welds in four different categories: This code and all revisions will be electronically maintained. Signed original copy of document located at AMSTA-TR-E. – Stud Welding – Non-Critical Welding Recommendations for change must be submitted in writing to U.S.
Army Tank-Automotive and Armament Research, Development and Engineering Center (TARDEC), Attention AMSTA-TR-E/MEPS. Consensus of the standing Weld Team is required for revisions to this code. – Critical Welding (Except Ballistic Structures) – Ballistic Welding Generally, the requirements for welds in the latter three categories can be related to the prior military specifications, as follows: TARDEC/UDLP Weld Team • Quality standards of Section 8, related to welding of attachments, is based upon MIL- STD-372, Class B. Charter Members x Michael W. Davis – UDLP • Quality standards of Section 9, related to welding of primary nonballistic structures, is based upon MIL-STD-372, Class A.
x Steven W. Taylor – UDLP x Richard J. Rush – UDLP • Quality standards of Section 10, related to welding of structures subject to ballistic attack, is based upon MIL-STD-1946. x David Berridge – UDLP x Marvin Kohn - UDLP For simplicity, this document can be divided into separate working sections. Sections 7 through 10 describe the requirements for specific weld categories and should be used to control welding of these individual categories. They should be x Terry A. Higgins – TARDEC x Joe B.
