The AS/NZS 1554.5:2011 standard is titled "Structural Steel Welding: Welding of Steel Structures Subject to High Levels of Fatigue Loading." This standard sets out the requirements for welding steel structures that are subject to high levels of fatigue loading. The standard covers various welding processes, including manual metal-arc welding, submerged arc welding, gas metal-arc welding, gas tungsten-arc welding, flux-cored arc welding, electroslag welding, and electrogas welding.

The standard is applicable to steel structures composed of steel plate, sheet, sections, hollow sections, built-up sections, castings, and forgings. However, it is limited to steel parent material with a specified minimum yield strength not exceeding 500 MPa. The standard applies to structures that comply with AS 3990, AS 4100, AS/NZS 4600, or NZS 3404.1. For structures with dynamically loaded welded joints, the standard only applies to welded joints that comply with the fatigue provisions of AS 3990, AS 4100, NZS 3404.1, or other applicable standards.

In addition to structures complying with the above standards, the AS/NZS 1554.5:2011 standard also applies to welding in cranes, hoists, road and pedestrian bridges, and other dynamically loaded structures. It also covers welding in applications other than structural steelwork. Further information on this standard can be found in the WTIA Technical Note 11.
