should show the general arrangement of the parts to be welded. Where
applicable, the root spacing and the details of weld groove may be
specified.
(At the option of the contractor, sketches may be attached to illustrate joint
design, weld layers and bead sequence, e.g., for notch toughness A-Root Gap,
B-Root face
