Full title and description

St AS NZS 1554.1-2014 (2017) — AS/NZS 1554.1:2014 Structural steel welding — Part 1: Welding of steel structures. This joint Australia / New Zealand standard specifies requirements for the welding of steel structures made up of combinations of plate, sheet or sections (including hollow and built‑up sections), and also applies to castings and forgings; the 2014 edition has been amended by Amendment 1 (2015) and Amendment 2 (2017).

Abstract

AS/NZS 1554.1:2014 sets out mandatory and recommended requirements covering materials, welding consumables, weld types and sizes, details of welded connections (butt and fillet), weld quality categories, welder and procedure qualification, inspection and testing, and safety for the welding of structural steel. It is intended for use where welded steelwork forms part of structural designs and includes provisions and limitations for fatigue‑sensitive joints.

Scope

The standard applies to the welding of structural steelwork composed of combinations of plate, sheet and sections (including hollow sections and built‑up members), and to relevant castings and forgings. It addresses requirements for welding materials, consumables, welding procedure and welder qualification, joint details, design throat/thickness, permissible weld types, inspection, nondestructive testing and safety. The standard is limited to parent steels with a specified minimum yield strength not exceeding approximately 500 MPa and contains specific limitations and fatigue provisions when used with structural design standards.

Key topics and requirements

• Weld categories and design rules for butt and fillet welds (sizes, design throat, effective length/area, transition of thicknesses).
• Materials and welding consumables: parent materials, backing materials, electrodes, filler wires, flux and shielding gas requirements and care.
• Qualification: welding procedure specification (WPS), welding procedure qualification, welder qualification and ranges of qualification.
• Inspection, testing and acceptance criteria including nondestructive testing (NDT) requirements and categories of acceptance.
• Fatigue provisions and limitations when applied to dynamically loaded joints — guidance on which weld categories and detail categories are acceptable for fatigue service.
• Safety, welding equipment and workplace practices specific to welding operations.

Typical use and users

Used by structural and welding engineers, fabricators, welding supervisors, welding inspectors, certifying bodies and asset owners involved in the design, fabrication, inspection and qualification of welded steel structures for buildings, bridges, machinery and general steelwork. It is commonly referenced in project specifications and referenced by building and structural design guidance in Australia and New Zealand.

Related standards

AS/NZS 1554.1 is part of the AS/NZS 1554 series and is associated with other parts such as AS/NZS 1554.2 (stud welding), AS/NZS 1554.3 (stainless steels), AS/NZS 1554.4 / 1554.5 / 1554.6 etc. It also references and aligns with related standards on welding consumables and procedure qualification (for example ISO 15614‑1 and other welding and metal standards cited within the normative references).

Q: What does it cover?

A: It covers materials, allowable weld types and sizes, design throat/thickness rules for butt and fillet welds, welding consumables and their handling, welding procedure and welder qualification, inspection and acceptance criteria, NDT, and safety matters for welding of steel structures. It also includes fatigue and service limitations for dynamically loaded joints.

Q: Who typically uses it?

A: Structural and welding engineers, fabricators, welding supervisors and inspectors, certifying authorities, and project specifiers who need to ensure welded steelwork meets recognised engineering and quality requirements in Australia and New Zealand.
