AS NZS 1554.1-2014

Description

AS NZS 1554.1 – 2014 Edition – Structural steel welding, Part 1: Welding of steel structures

AS NZS 1554 Part 1 specifies requirements for the welding of steel structures made up of combinations of steel plate, sheet or sections, including hollow sections and built-up sections, or castings and forgings, by the following processes:

1. Manual metal-arc welding (MMAW).
2. Submerged arc welding (SAW).
3. Gas metal-arc welding (GMAW orMIG), including pulsed mode.Gas tungsten-arc welding (GTAW or TIG).
4. Flux-cored arc welding (FCAW).
5. Electroslag (including consumable guide) welding (ESW).Electrogas welding (EGW).

AS NZS 1554.1 is limited to the welding of steel parent material with a specified minimum yield strength not exceeding 500 MPa.
AS NZS 1554.1 applies to the welding of steelwork in structurescomplying with AS 3990, AS 4100, AS/NZS 4600 or NZS 3404.1. Where welded joints in these structures are governed by dynamic loading conditions, this Standard applies only to those welded joints that comply with the fatigue provisions of AS 3990, AS 4100 or NZS 3404.1, as limited by Item (ii) below, or the directlyequivalent fatigue provisionsof other application Standards.

Welded joints complying with theabove Standards are the following:

(i) Those that are not subject to fatigue conditions.
(ii) Those that are subject to fatigue conditions, where—

(A) the stress range in the welded joint complies with the permissible stress range
of stress categories C, D, E or F of AS 3990, or weld categories lower than or equal to detail category 112 of AS 4100 or NZS 3404.1; or
(B) the stress range in the welded joint is not greater than 80% of the permissible
stress range of stress category B of AS 3990.

In addition to the abovementioned structures, the Standard applies to the welding of cranes,hoists and other dynamically loaded structures, the welding ofroad and pedestrian bridges
and the welding of steelwork in applications other than structural.

NOTES:
1.Further information on this Standard, is given in WTIA Technical Note 11.
2.GMAW includes waveform controlled welding such as ‘synergic’, ‘programmable’, and‘microprocessor controlled’ processes (e.g. pulsed spray transfer or controlled short circuittransfer).
