AS/NZS ISO 3834 Certification is an assessment of welding quality management systems for structural steel manufacturers. It mainly evaluates welding system establishment, personnel qualifications, raw material control, product testing, and traceability management.

Scope of Application

AS/NZS ISO 3834 applies to all metal structure manufacturers performing permanent welding. It is widely used in structural steel, bridges, pressure vessels, energy equipment, marine engineering, rail transit, offshore engineering, and heavy equipment industries. This certification is also one of the essential prerequisites for entering the Australian and New Zealand markets through AS/NZS 5131 certification.

Certification Requirements

· Welding Procedure Qualification Record (PQR) and Welding Procedure Specification (WPS)

· Welder and welding operator qualifications

· Welding coordinators

· Non-Destructive Testing (NDT) personnel

· Material purchasing, identification and traceability control

· Inspection plans and quality records

· Testing equipment management and calibration

· Base material storage and post-weld heat treatment

· Subcontractor management

· Non-conformity control and corrective actions

· Document control and continual improvement

Certification Levels

· AS/NZS ISO 3834.2 – Comprehensive Quality Requirements: The highest level with the most stringent control requirements, suitable for high-risk applications.

· AS/NZS ISO 3834.3 – Standard Quality Requirements: Suitable for general structural steel fabrication with balanced quality and cost requirements.

· AS/NZS ISO 3834.4 – Elementary Quality Requirements: Basic requirements suitable for lower-risk products.

Certification Process

· Application submission

· Pre-assessment and standard implementation

· Welding quality management training and system establishment

· Welding procedure qualification and personnel examination

· Internal audit and simulated assessment

· Document review by certification body

· On-site audit covering welding processes from design, materials, fabrication to inspection

· Issuance of certificate and periodic surveillance audits
