Welding to AS/NZS 1554.1 of Boron Containing Steel

Recent reports indicate that some imported steel may show elevated levels of boron; traditionally steel in Australia and New Zealand has been made without boron additions.  The welding requirements of AS/NZS 1554 have been established ...

Welding to AS/NZS 1554.1 of Boron Containing Steel

Written by Dr Michail Karpenko, Dr Stephen Hicks, Alistair Fussell on May 2nd, 2016.      0 comments

Recent reports indicate that some imported steel may show elevated levels of boron; traditionally steel in Australia and New Zealand has been made without boron additions.  The welding requirements of AS/NZS 1554 have been established without considering the effect of boron as an alloying element. This article discusses steps that should be undertaken by the fabricator to ensure the integrity of the steel fabrication work when welding structural steel with elevated boron levels.

Heat Input Limits of Welding Consumables for Earthquake Resisting Structures

Written by Alan McClintock; Kevin Cowie on April 24th, 2014.      0 comments

The Steel Structures Standard, NZS 3404, references the AS/NZS 1554 suite of standards for compliance of welding consumables. NZS 3404 includes additional requirements limiting the heat input in the deposited weld metal for welds subject to earthquake loads or effects. This article discusses the background to these requirements, identifies welding processes restricted by the heat input limits and how to qualify welding process that are restricted by the heat input limits.

Welding Consumables and Design of Welds

Written by Kevin Cowie; Alan McClintock on February 28th, 2014.      0 comments

The Steel Structures Standard, NZS 3404, references the AS/NZS 1554 suite of standards for compliance of welding consumables. New editions of the AS/NZS 1554 suite of welding Standards have recently been published and these refer to newly published editions of the AS/NZS Standards for welding consumables. Over the last few years, Australia and New Zealand have adopted the harmonized ISO welding consumable classification system. These changes in welding consumable classification system impact on structural engineers designing fillet welds and partial penetration butt welds.

Withdrawal of Welder Qualification Standard NZS 4711

Written by Alistair Fussell; Clark Hyland; Charles Clifton on September 26th, 2010.      0 comments

Some changes to the way NZ welders qualify for structural welding will result from the Standards NZ announcement in March 2010 that NZS 4711 is to be withdrawn. With effect from 1 April 2011, new or renewal welder qualifications will not be available under this Standard. For most users of NZS 4711, AS/NZS 2980:2007 Qualification of Welders for Fusion Welding of Steels, will become the standard for welder qualification.
