(2)
Grind cut-away edges to forty!-five degree bevel. This will help to ensure complete weld penetration.
(3)
Position corner fitting as follows: (a) Corner fitting should fit closely, with maximum gap of 5/64 inch
between the casting and the end and side rails.
(b) Grind rails so that corner fitting fits closely and is on level.
(c) Tack weld corner fitting into position.
(d) Measure distances D1, D2, D3, D5, Ds, and D6 indicated in Figure 3-1. Each of these measurements
is made between the exact centers of the corner fitting openings. Subtract D2 from D1, D4 from D3
and D5 from D6. If the results exceed the maximum tolerances listed in Figure 3-1, reposition the
corner fitting.
(e) Measure the overall length and width of the container. Measurements must be within the maximum
tolerances listed in Figure 3-1.
(f) Adjust corner fitting position to meet maximum tolerances. Remeasure and adjust as necessary.
(4)
Continuously weld corner fitting in place using low hydrogen welding rod. Welds must be uniform, free of
scale, pin and blow holes, and with full penetration.
3-2. Side, End and Roof Panels.
a.
Method of Repair. Repair damage to side, end and roof panels in one of four ways, depending on the kind of
damage. Holes may be repaired by filling with weld metal, patching, filling the hole with an insert, or replacing
the panel. Temporary repairs to loaded containers may be made with fiberglass patches according to procedures
in paragraph 2-6.
(1)
Fill holes less than one quarter inch in diameter with weld metal.
(2)
Patch holes larger than a quarter inch in diameter which occur on a flat surface. Damaged surfaces which
can be returned to their original shape should be smoothed out and patched.
(3)
Use an insert instead of a patch whenever the hole is not limited to a single flat surface, and/or when
denting is so severe that the metal could not be reshaped to its original profile.
(4)
Replace the side or end panel when an insert of identical corrugation shape and depth is not available for
repair of a damaged section. The shape of the corrugation is not as critical when replacing complete
panels, as long as the number and depth of the corrugations on the panel is the same. Replace the panel
if damage has affected more than fifty percent of the panel.
