THE WELD OF METAL
Australian Standards for welding in
metal have been recently enhanced with
international expertise brought into
focus. Two sections of the AS/NZS 2205
series have recently been superseded to
adopt the international guidance from
ISO. The following two standards are a
sample of the work being done in this
space by the technical committee:
AS/NZS 2205.4.1:2019, Methods for
destructive testing of welds in metal
Method 4.1: Fracture test
The objective of this Standard is to
specify the sizes of test specimen and
the procedures for carrying out fracture
tests in order to obtain information
about types, sizes and distribution
of internal imperfections such as
porosities, cracks, lack of fusion, lack of
penetration and solid inclusions on the
fracture surface.
This Standard is identical with,
and has been reproduced from ISO
9017:2017, Destructive tests on welds in
metallic materials - Fracture test.
AS/NZS 2205.5.1:2019 Methods
for destructive testing of welds in
metal, Method 5.1: Macroscopic and
microscopic examination of welds
The objective of this Standard is to
provide recommendations for specimen
preparation, test procedures and their
main objectives for macroscopic and
microscopic examination.
Users of this Standard should be
aware that its test methods include the
methods specified in the superseded
AS 2205.5.1 and now includes
additional methods for microscopic
examination not previously available.
This Standard is identical with,
and has been reproduced from ISO
17639:2003, Destructive tests on welds
in metallic materials — Macroscopic and
microscopic examination of welds.
THIS IS NOT A DRILL…
Self-drilling screws were on the agenda
in recent months with an industry
forum held by Standards Australia. The
purpose was to engage stakeholders in a
comprehensive conversation highlighting
the current gap in standards on self-
drilling screws, working towards finding
an acceptable solution for the industry.
Some interesting and challenging
subjects were raised and discussed at
length, with the group making great
progress on how to push forward and
deliver on what is needed. Watch out for
some future proposals to produce a new
edition of AS 3566.2-2002 Self-drilling
screws for the building and construction
industries - Corrosion resistance
requirements.
