TM 55-8115-203-23 & P (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. 3-3
