Cut surface roughness exceeding these values shall be repaired by grinding to give a value less than
the specified roughness. Grinding marks shall be parallel to the direction of the cut.
Notchesand gouges, not closer than20t(where tis the component thickness) and not exceeding 1%
of the total surface area on an otherwise satisfactory surface, are acceptable provided that
imperfections greater than t/5 but not exceeding 2 mm in depth are removed by machining or
grinding. Imperfections outside the above limits shall be repaired by welding in accordance with
AS/NZS 1554.1.
A re-entrant corner shall be shaped notch free to a radius of at least 10 mm.
14.3.4 WeldingWelding shall comply with AS/NZS 1554.1 or AS/NZS 1554.5 as appropriate
(seeClause 11.1.5), and welding of studs shall comply with AS 1554.2.
14.3.5 Holing
14.3.5.1 GeneralAround hole for a bolt shall either be machine flame cut,or drilled full size, or
subpunched 3 mm undersize and reamed to size, or punched full size.
Aslotted hole shall be either machine flame cut, or punched in one operation, or formed by drilling
two adjacent holes and completed by machine flame cutting.
Handflame cutting of a bolt hole shall not be permitted exceptas a site rectification measure for holes
in column base plates.
Apunched hole shall only be permitted in material whose yieldstress (fy) does not exceed 360 MPa
and whose thickness does not exceed (5600/fy) mm.
14.3.5.2 Holesize The nominal diameter of a completed hole other than a hole in a base plate shall
be2 mm larger than the nominal bolt diameter for a bolt not exceeding 24 mm in diameter, and not
more than 3 mm larger for a bolt of greater diameter.
Fora holein a base plate, the hole diameter shall be not more than 6 mm greater than the anchor bolt
diameter.A special plate washer of minimum thickness 4 mm shall be used under the nut if the hole
diameter is 3 mm or more larger than the bolt diameter.
An oversize or slotted hole and the limitations on its use shall comply with the following:
(a) Oversize or slotted holeAn oversize or slotted hole shall be permitted, provided that the
following requirements are satisfied:
(i) Anoversize hole shall not exceed 1.25df
or (df+ 8) mmin diameter, whichever is the
greater, where df
is the nominal bolt diameter, in millimetres.
