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