CHAPTER 1 SCOPE
1-1 SCOPE. This document contains the requirements for the qualification of welding and brazing procedures, welders, welding operators, brazers, and brazing operators that must be met prior to any production fabrication. It includes manual, semiautomatic, automatic, mechanized, and robotic welding and brazing of ferrous, nonferrous, and dissimilar metals. The qualification tests required by this document are devised to demonstrate the adequacy of the welding or brazing procedures and to demonstrate the ability of welders, brazers, welding operators, and brazing operators to produce sound welds or brazes. 1-1.1 SAFETY. Safety and health issues and concerns are beyond the scope of this document and are therefore not addressed herein. Safety and health information is available from the following sources:
a. Department of the Navy – Office of The Chief of Naval Operations: (1) OPNAVINST 5100.23 (series) (2) OPNAVINST 5100.19 (series) b. American Welding Society: (1) ANSI Z49.1 (2) AWS Safety and Health Fact Sheets (3) Other safety and health information on the AWS website c. Material or Equipment Manufacturers: (1) Safety Data Sheets supplied by materials manufacturers (2) Operating Manuals supplied by equipment manufacturers d. Applicable Regulatory Agencies.
Work performed in accordance with this document may involve the use of materials that have been deemed hazardous and may involve operations or equipment that may cause injury or death. This document does not purport to address safety and health risks that may be encountered. Users of this document shall comply with appropriate safety programs to address such risks as well as to meet applicable regulatory requirements. 1-2 PREVIOUSLY QUALIFIED PROCEDURES AND PERSONNEL. Except as required by 1-2.1 and 1-2.2, procedures and personnel previously qualified to earlier revisions of this document, for which records are available and qualifications have been maintained, are acceptable for use to this revision. However, the authorized representative may require requalification to this revision on a case-by-case basis where both of the following apply: a. There are specific concerns about the adequacy of procedures or ability of personnel to produce welds of intended integrity or which meet requirements of the applicable fabrication document, and b. The existing qualification requires requalification by this document. These requirements also apply to the visual inspection training of personnel required by this document. It is not the purpose of this document to require extensive requalification of previously qualified procedures or personnel. Changes to existing procedures and procedure and personnel qualifications, and qualification of new procedures and personnel performance, shall be accomplished in accordance with the requirements of this document. New procedures developed from existing qualifications shall conform to this revision. 1-2.1 MIL-120XX PROCEDURES. Procedures involving the use of MIL-12018-M2 or MIL-120S-1 electrodes previously qualified to other revisions of this document are not approved for use when this revision is invoked, unless specifically approved by NAVSEA.
