We’re thrilled to announce that we have been recertified for UKAS BS EN ISO 3834-2:2021 Welding Quality Management System (WQMS), an internationally recognised welding standard.

This outstanding achievement highlights the exceptional hard work and dedication of our team. It further demonstrates our commitment to providing the best quality welding that’s possible.

ABOUT ISO 3834-2:2021 WQMS

ISO 3834-2:2021 WQMS is a globally recognised standard that outlines the quality requirements needed for the fusion welding of metallic materials. It provides us a best-practice framework focusing on welding coordination, personnel competence, and proper equipment usage.

The standard defines quality across three levels of work:

  1. Grade 4: Basic
  2. Grade 3: Medium
  3. Grade 2: High


We’re certified to Grade 2, the most comprehensive Quality Standard available, enabling us to deliver the best level of quality currently possible for all our welding work.

To adhere to this rigorous standard, we have implemented all necessary controls, processes, and procedures to ensure alignment with best practice methodology.


We first gained certification in back in 2015 and undergo an annual reassessment by TUV UK Ltd, our Accreditation Body.

On January 29th, TUV UK conducted a recertification audit, performing an in-depth analysis of our processes, procedures, and systems to ensure our ongoing compliance with the standard.

Having passed our audit with flying colours, we are now certified for the next three years and only need to pass an annual surveillance audit, a much simpler process, rather than going through full recertification again

Auditor feedback was extremely positive, confirming that our Quality Management System is working to an extremely high standard.

WHY ISO 3834-2:2021 WQMS

ISO 3834-2:2021 is a crucial part of our overall Quality Management System, complementing other internationally recognised standards, including:


This integrated approach ensures we provide the highest quality welding services, both in our workshop and onsite.

Used in addition to testing, the ISO 3834-2 standard dictates the quality criteria for producing welded constructions and controls our production process to meet these criteria, so we consistently produce high quality welds, each and every time.
