3.3.3
Welding Procedures. All welding should be performed in
accordance with written and approved welding procedures (see
3.3.2). Welding procedures must include requirements for
documenting welder qualification and criteria for weld joint
acceptance. The applicant must make available the written
welding procedures and the welder qualification records,
including any destructive/nondestructive test records required
for proof-of-welder qualification on the specific material
selected, for SCA review. Any repair involving heat or welding
should be accomplished in accordance with approved written
procedures and subjected to the tests and inspections specified
for construction. All welded pipe joints must be documented and
inspected in accordance with the P-1 requirements in NAVSEA
S9074-AR-GIB-010/278 or ANSI/ASME B31.1, Power Piping, as
supplemented by NAVFAC required inspections and documentation.
The fabrication activity must provide traceability between the
joint record and the actual welded joint for each welded pipe
joint or structural weld joint.
The following procedures are typical of satisfactory welding
practices:

Brazing Procedures. In piping systems fabricated with
3.3.4
brazed joints, all brazing should be performed in accordance with
written and approved brazing procedures (see 3.3.2) which meet or
exceed the requirements of Class P-3A, Special Category I, Table
3.1, described in NAVSEA 0900-LP-001-7000, Fabrication and
Inspection of Brazed Piping Systems. Brazing procedures must
