Sketches, Production Drawings, Weld Symbols or Written Description
Should show the general arrangement of the parts to be welded. Where
applicable, the root spacing and the setails of weld groove may be
specified.
(At the option of the Mfgr., sketches may be attached to illustrate joint
design, weld layers and bead sequence, e.g. for notch toughness proce-
dures, for multiple process procedures, etc.)
