WELDING THEORY - OD1650 - LESSON 1/TASK 1
(2) When fillet welding extends for the full distance between abrupt changes in the
direction of the welding, no length dimension need be shown on the welding symbol.
(3) Specific lengths of fillet welding may be indicated by symbols in conjunction with
dimension lines (figure 9, view I, on the previous page).
Extent of Fillet Welding.
o.
(1) When it is desired to show the extent of fillet welding graphically, one type of
hatching, with or without definite lines, shall be used.
(2) Fillet welding extending beyond abrupt changes in direction of the welding will be
indicated by means of additional arrows pointing to each section of the joint to be welded (figure
9, view H), except when the weld-all-around symbol is used.
Dimensioning of Intermittent Fillet Welding.
p.
(1) The pitch (center-to-center spacing) of intermittent fillet welding will be shown as the
distance between centers of increments on one side of the joint.
(2) The pitch of intermittent fillet welding will be shown to the right of the length
dimension (figure 9, view A).
(3) Chain intermittent fillet welding will be shown in figure 9, view F.
(4) Staggered intermittent fillet welding will be shown in figure 9, view G.
Termination of Intermittent Fillet Welding.
q.
(1) When intermittent fillet welding is used by itself, the symbol indicates that
increments will be located at the ends of the dimensional length.
(2) When intermittent fillet welding is used between continuous fillet welding the symbol
indicates that spaces equal to the pitch minus the length of one increment shall be left at the ends
of the dimensioned length. Separate symbols will
