AS/NZS 5131 is the authoritative Australian and New Zealand standard for Structural Steel Fabrication and Erection. It evaluates the quality management capability of structural steel manufacturers, including welding systems, personnel qualifications, raw material control, product testing and traceability management.

Key Certification Requirements

· Welding Procedure Qualification Record (PQR) and Welding Procedure Specification (WPS) shall comply with AS/NZS 1554.1.

· Approved welding procedures and complete qualification records are required.

· Welding plans shall define welding sequence, preheat requirements and inspection points.

· Welding shall be managed under an appropriate quality management system, with AS/NZS ISO 3834 recommended.

· Quality documentation, Quality Plan and Inspection and Test Plan (ITP) shall be established.

· Welding personnel shall meet applicable requirements including AS/NZS 1554, AS/NZS 2980, ISO 9606-1, ISO 14731, AS/NZS 2214 and AS ISO 9712.

Product Testing and Inspection

· Non-Destructive Testing (NDT), including UT, MT, RT and PT.

· 100% visual inspection (VT) of welds.

· Coating thickness inspection and surface treatment verification.

· Material testing certificates for steel materials.

Traceability Management

· CC2: Partial Traceability.

· CC3/CC4: Full Traceability, where welders and welding procedures can be traced to individual welds.
