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.)
