WELDING THEORY - OD1650 - LESSON 1/TASK 1
be used for intermittent and continuous fillet welding when the two are used in combination
(figure 9, view I, on page 20).
Surface Contour of Fillet Welds.
r.
(1) Fillet welds that are to be welded approximately flat faced, without recourse to any
method of finishing, will be shown by adding the flush contour symbol to the weld symbol,
observing the usual location significance (figure 9, view J).
(2) Fillet welds that are to be made flat faced by mechanical means will be shown by
adding both the flush contour symbol and the user's standard finish symbol, observing the usual
location significance (figure 9, view K).
(3) Fillet welds that are to be mechanically finished to a convex contour will be shown by
adding both the convex contour symbol and the user's standard finish symbol to the weld
symbol, observing the usual location significance (figure 9, view D).
NOTE
The finish symbols referred to in (2) and (3) above indicate the
method of finishing ("C" = chipping; "G" = grinding; "H" =
hammering; "M" = machining) and not the degree of finish.
Plug and Slot Welding Symbols.
s.
(1) General. Neither the plug weld symbol nor the slot weld symbol will be used to
designate fillet welds in holes.
(2) Arrow and Other Side Indication of Plug and Slot Welds. Holes or slots in the arrow
side member of a joint for plug or slot welding will be indicated by placing the weld symbol on
the side of the reference line toward the viewer (refer to figure 6, view A, on page 14). Holes or
slots in the other side member of a joint are indicated by placing the weld symbol on the side of
the reference line away from the viewer (refer to figure 6, view B).
