MIL‐DTL‐14522E
3.5.2 Treatment and painting. Each component shall be treated and painted in accordance with MIL-
T-704 except that, unless otherwise specified (see 6.2), the finish coat shall be semigloss black enamel,
Color No. 27038 in accordance with FED-STD-595.
3.6 Workmanship.
3.6.1 Casting. All cast strong room components shall be free from harmful extraneous material such
as sand, dirt, pits, sprues, scale and flux. Rework shall be limited to procedures which do not reduce
strength or affect function.
3.6.2 Metal fabrication. Metal used in fabrication shall be free from kinks and sharp bends. The
straightening of material shall be done by methods that will not cause injury to the material; corners shall
be square and true. Flame cutting, using tips suitable for the thickness of the steel, may be employed
instead of shearing and sawing, providing all slag is removed after burning. All bends shall be made with
controlled means to ensure uniformity of size and shape. Precaution shall be taken to avoid overheating.
Heated steel shall be allowed to cool slowly. External surfaces shall be free of burrs, sharp edges, and
corners, except when sharp edges or corners are required or where they are not detrimental to safety.
3.6.3 Machine work. Tolerance and gages for metal fits shall conform to the limits specified on
drawing 13218E8075 and to the standard of the industry.
3.6.4 Welding. The surfaces to be welded shall be free from rust, scale, paint, grease, and other
foreign matter. Welds shall transmit stress without permanent deformation or failure and shall have no
crack type defects when the component is completed. Parent materials, weld filler metals, and fabrication
techniques shall be as required to enable the components to conform to the examination and test
requirements specified in Section 4. Parts to be joined by fillet welds shall be brought into as close
contact as possible and in no event shall be separated by more than 1/16 inch, unless appropriate
bridging techniques are used. Unless otherwise specified, the welding process used in fabrication of the
component shall be at the option of the contractor.
3.6.5 Welders. Before assigning any welder to welding work covered by this document, the
contractor shall provide the contracting officer with certification that the welder has passed qualification
tests as prescribed by either of the following listed codes for the type of welding operation to be
performed and that such qualification is effective as defined by the particular code:
AWS D1.1/D1.1M, Structural Welding Code-Steel
ASME Section IX, Qualification Standard for Welding and Brazing Procedures, Welders, Brazers,
and Welding and Brazing Operators
Contractors who only make horizontal welds need not qualify welders for "all position welding". Subject to
approval by the Government, the contractor's standard welder qualification may be substituted in lieu of
the above codes provided that the contractor's procedure is equivalent to the above codes. The
contractor shall be responsible for determining that automatic welding equipment operators are capable
of producing quality welds. For the purpose of this document, automatic welding equipment operators
shall be considered welders and subject to the qualification procedures outlined above.
4. VERIFICATION
4.1 Certificates of compliance. When certificates of compliance are submitted, the Government
reserves the right to inspect such Items to determine the validity of the certification.
