ISO 3834-2 certification
Demonstrate welding quality with certification for fusion welding of metallic materials. Bureau Veritas provides experienced auditors, a dedicated contact and a clear process.
WHY ISO 3834-2 certification?
Welding quality directly affects the safety, reliability and service life of welded structures. Customers, clients and technical specifications increasingly require demonstrable control of welding processes.
Welding is a special process: weld quality cannot be fully verified by final inspection alone. ISO 3834-2 therefore requires control throughout the welding process, from technical review and welding coordination to qualifications, inspection, documentation and traceability.
ISO 3834-2 certification demonstrates that your organisation meets comprehensive quality requirements for fusion welding of metallic materials. Bureau Veritas Certification provides experienced auditors, a dedicated contact and a clear process through to certificate issuance.
What are the benefits of ISO 3834-2 certification?
-
Demonstrate control of welding processes
Structure and document your welding processes to demonstrate conformity with comprehensive quality requirements for fusion welding of metallic materials.
-
Build customer confidence
Certification demonstrates a professional approach to welding quality, supporting customer assessments, technical specifications, tenders and supplier selection.
-
Manage personnel, procedures and inspections
The standard addresses welding coordination, welders, procedure specifications and qualifications, inspection, testing and subcontracting. This strengthens control of the factors that determine welding quality.
-
Strengthen traceability and quality assurance
Manage documentation, materials, welding consumables, checks and records systematically, making welding quality easier to demonstrate and monitor.
Why choose Bureau Veritas Certification?
Expertise in welding processes and quality: We assess the elements needed to demonstrate control of welding, including welding coordination, procedure qualifications, welders, inspection, non-destructive testing, welding consumables and traceability.
A single point of contact: Your dedicated contact coordinates planning, audits, certificate issuance and changes. This keeps the process clear when multiple technical documents, qualifications, inspections and production sites are involved.
Combine with ISO 9001: Many organisations combine ISO 3834-2 with ISO 9001. We can review how to coordinate audits efficiently when you need welding quality and quality management assessed together.
Auditors and inspectors who know your industry: Our auditors and inspectors have experience in technical processes and industrial applications, helping them assess your operations, documentation and production environment effectively.
A practical certification process: We tailor the process to your scope, welding processes, production sites and relevant quality requirements, keeping it clear and manageable.
Transfer within your certification cycle: We can take over existing certification without starting again. We review your certificate, audit reports and documentation to continue within your current certification cycle where possible.
How do ISO 3834-2, ISO 3834-3 and ISO 3834-4 differ?
ISO 3834 defines three levels of quality requirements for fusion welding of metallic materials. The appropriate level depends on the complexity and risks of the work, technical specifications and client requirements.
ISO 3834-2 – Comprehensive quality requirements
For complex or critical welding that requires extensive control, documentation and traceability, including where clients, technical specifications or applicable standards require comprehensive quality assurance.
ISO 3834-3 – Standard quality requirements
For less complex welding that still requires clear quality assurance, with an emphasis on procedures, qualifications and production checks.
ISO 3834-4 – Elementary quality requirements
For simpler welding with limited risks and less extensive documentation requirements, focusing on basic control of the welding process.
