assembly in accordance with MS53052 shall be furnished. The location
of the bracket shall be such that it is accessible to personnel and
provides clearance to remove and emplace a 5-gallon container
conforming to MIL-C-1283.
3.37 Workmanship.
3.37.1 Castings and forgings. All parts, components and assemblies
of the forklift which include castings and forgings shall be clean of
harmful extraneous material such as sand, dirt, sprues, scale and
flux. Rework shall be limited to procedures which do not reduce
mechanical properties or affect function.
3.37.2 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. All bends shall be made with controlled means to insure
uniformity of size and shape. Precaution shall be taken to avoid
overheating. Heated steel shall be allowed to cool slowly, except in
the performance of designed heat treatment. External surfaces shall
be free from burrs, sharp edges and corners, except when sharp edges
or corners are required or where they are not detrimental to safety.
3.37.3 Welding. The surfaces of parts to be welded shall be free
from rust, scale, paint, grease, mill scale that can be removed by
chipping and wire brushing, and other foreign matter. Welds shall
transmit stress without permanent deformation or failure when the
parts connected by the welds are subjected to proof and service
loading. Parent materials, weld filler metals, and fabrication
techniques shall be as required to enable the forklift 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 3/16
inch, unless appropriate bridging techniques are used. The welding
process used in fabrication of the forklift shall be at the option of
the contractor.
3.37.3.1 Welders. Before assigning any welder to manual welding
work covered by this specification, the contractor shall obtain
certification that the welder has passed qualification tests as
prescribed by either of the following listed codes or the
manufacturer's commercial code, for the type of welding operations to
be performed and that such qualification is effective as defined by
the particular code:
