5.31 Weld Tabs (See 5.2.2)
5.31.1 Use of Weld Tabs. Welds shall be terminated at
the end of a joint in a manner that will ensure sound
welds. Whenever necessary, this shall be done by use of
weld tabs aligned in such a manner to provide an extension
of the joint preparation.
5.31.2 Removal of Weld Tabs for Statically Loaded
Nontubular Structures. For statically loaded nontubular
structures, weld tabs need not be removed unless
required by the Engineer.
5.31.3 Removal of Weld Tabs for Cyclically Loaded
Nontubular Structures. For cyclically loaded nontubular
structures, weld tabs shall be removed upon completion
and cooling of the weld, and the ends of the weld
shall be made smooth and flush with the edges of abutting
parts.
5.31.4 Ends of Welded Butt Joints. Ends of welded
butt joints required to be flush shall be finished so as not
to reduce the width beyond the detailed width or the actual
width furnished, whichever is greater, by more than
1/8 in. (3 mm) or so as not to leave reinforcement at each
end that exceeds 1/8 in. (3 mm). Ends of welded butt
joints shall be fared at a slope not to exceed 1 in 10.
