ABOUT ISO 3834-2:2021 WQMS

BS EN ISO 3834-2:2021 is an internationally recognised standard defining the quality requirements for the fusion welding of metallic materials.

It ensures all welding activities are:

  • Planned and controlled.
  • Delivered by competent personnel.
  • Completed using qualified procedures and equipment.
  • Fully traceable and compliant throughout.

 

The standard underpins both our workshop fabrication and on-site welding, ensuring consistent, repeatable, high-quality results across all projects.

CERTIFIED TO THE HIGHEST LEVEL

ISO 3834-2:2021 is structured across three levels:

  • Grade 4 – Basic
  • Grade 3 – Standard
  • Grade 2 – Comprehensive (Highest Level)

 

REL continues to be certified to Grade 2, confirming that our welding processes, controls, and personnel meet the very highest levels of quality assurance.

ABOUT OUR AUDIT

We first achieved ISO 3834 certification in 2015 and undergo annual reassessment by our accredited body TÜV UK.

The latest audit included a detailed review of REL:

  • Welding procedures (WPS).
  • Personnel competence.
  • Material traceability.
  • Equipment calibration.
  • Inspection, testing & NDT.
  • Quality documentation.

 

Achieving zero findings across all areas demonstrates that our Welding Quality Management System continues to operate at an exceptionally high level.

WHY ISO 3834-2:2021 MATTERS

ISO 3834-2 forms a key part of the REL wider quality framework alongside:

  • ISO 9001 Quality Management System.
  • BS EN 1090-1 Factory Production Control.

 

This ensures all welding and fabrication activities are delivered safely, efficiently, and in full compliance with recognised standards.
