AS/NZS ISO 3834 Certification

AS/NZS ISO 3834 Quality requirements for fusion welding of metallic materials specifies the production control requirements expected for fusion welded products globally, whether fabricated on-site or in a workshop. It is the internationally recognised benchmark for welding quality.

Certification increases the likelihood of global supply chain opportunities and repeat business, and increases the technical knowledge of all welding personnel, bolstering profitability. AS/NZS ISO 3834 considers all aspects that could affect weld quality—it seeks to control the entire lifecycle of the welding process, from design right through to inspection. This type of approach is essential because it is impossible to undertake complete verification of a welded joint without destroying it.

Unfortunately, inspection after completion does not guarantee weld serviceability. As such, quality must be built into the welding process, right from the very beginning.

Benefits of Certification

There are multiple benefits associated with certification to AS/NZS ISO 3834. These include benefits for fabricators and purchasing organisations.

  • Compliance: AS/NZS ISO 3834 certification demonstrates that you have the ability to deliver a compliantly welded product, on time and on budget, including compliance with normative requirements such as AS 5100.6:2017.
  • Efficient Processes: Obtain AS/NZS ISO 3834 certification for improved efficiency in processes and procedures. This reduces costs and overheads, material and consumables waste, and production time.
  • Client Satisfaction: Clients use AS/NZS ISO 3834 certified organisations again and again, due to their efficient processes and reduction in production time and costs.
  • Technical Knowledge: All personnel, from trades and inspectors to supervisors and managers, see an increase in technical knowledge from obtaining AS/NZS ISO 3834 certification.
  • Global Supply Chain Opportunities: With AS/NZS ISO 3834 certification, you increase your opportunities to expand into new market sectors including the global supply chain.
  • Reduced Risk: Reducing risks of error means reducing project costs. AS/NZS ISO 3834 certification significantly reduces failures and miscalculations, keeping projects within schedule and budget.

What is AS/NZS ISO 3834 Certification?

AS/NZS ISO 3834 is a factory production control system designed to complement quality management systems such as ISO 9001. It helps businesses to improve their efficiency and productivity, which leads to great profitability and client satisfaction. AS/NZS ISO 3834 is recognised around the world as a minimum benchmark for welding quality.
