Austube Mills update test certificates to align with revised welding standards

Austube Mills has revised their structural steel hollow sections and profiles test certificates so as to comply with the 2014 revision of the AS/NZS 1554 series of Structural Steel Welding Standards, specifically parts 1, 5 and 7.

 In order to comply with this last revision, Austube Mills added boron to the listed chemical elements on their test certificates.

 This level of boron is less than or equal to 0.0006 per cent (or six parts per million), which is within the AS/NZS 1554 limit of 0.0008 per cent, thereby allowing Austube Mills products to be deemed ‘prequalified’ and compliant with the revised Standards.

 Fabricators in the building and construction sectors need to be aware of this important amendment to AS/NZS 1554 and its implications with the Building Code of Australia (BCA) as compliance to this standard can reduce the risk of structural failure or the need to replace the product.

 In lieu of the more rigorous qualified procedures, prequalified welding procedures are used to ensure the weld metal and heat-affected zone metal are in serviceable conditions after welding, and are permitted within AS/NZS 1554 subject to other nominated prequalification provisions.

 Therefore, as Austube Mills products are prequalified, fabricators can safely adopt ‘prequalified’ welding procedures, providing the other nominated provisions have been complied with.

 To further meet the Deemed-to-Satisfy provisions of the BCA (comprising Volumes 1 and 2 of the National Construction Code), compliance with the amended welding Standards along with the current version of AS/NZS 1163 (structural steel hollow sections), is also required.
