What is it?
For fabricators, ISO 3834 goes beyond ISO 9001 to demonstrate their competence in fusion welding processes.
A fabricator with an ISO 3834 certification stands out against the rest, as it shows they've been independently assessed for welding. One of the key elements is that it requires the manufacturer to demonstrate the competence of their welding coordinators.
Compliance with ISO 3834 Parts 2, 3 or 4 as appropriate, is now mandatory in many EN pressure vessel and construction standards.
What we do.
Lloyd’s Register is a globally accredited certification body for ISO 3834. For fabricators , having an ISO 3834 certification from LR provides an authoritative, globally recognized reference of commercial value. That value lies in our long history of certifying welders, welding operations and welding quality procedures according to several international standards.
We can certify your company to Parts 2, 3, and 4 of the ISO 3834 standard:
- Part 2 – Comprehensive Quality Requirements
- Part 3 – Standard Quality Requirements
- Part 4 – Elementary Quality Requirements
Overview of the ISO 3834 certification process
An examination of the company's welding quality management system helps identify areas which require attention and correction.
The scheme requires you to complete a detailed questionnaire about the capabilities of your facility.
This includes qualifications and experience of the nominated welding coordination personnel.
In the third step, you conduct a self-audit against the ISO 3834-2 audit checklist.
The audit is a two-stage process:
Stage 1 identifies areas within the welding quality management system which require attention.
Stage 2 is implementation confirmation, where the assessment team will
examine specific contracts to assess compliance with customers' expectations.
Once issued, the ISO 3834 certificate is valid for five years.
An annual surveillance audit by a qualified assessor is required to maintain the approval.
