Demonstrate your welders are competent.

Independent assurance, from KLL’s welding experts.


The qualification of welders and welding operators by a third party organisation is required for most safety-critical, pressure-related manufacturing and fabrication.  

This is done through welder qualification tests. The tests allow welders to demonstrate their ability to follow verbal and written welding instructions according to a national code, standard or regulation.

Need help with your welder or welding operator qualification tests?

KLL provides independent, third-party witnessing of welder and operator qualification tests. We also endorse welder certification according to national, European and international recognised standards, including:

  • EN ISO 9606
  • EN 287
  • ISO 14732
  • AWS

KLL is able to provide this service in two ways:

  • KLL attends the clients’ facilities directly
  • KLL attends the welding school

Looking for your Lloyd’s Register-issued welding certificate, or looking to renew your LR-endorsed certificate?

LR does not provide copies of any welding certificates we endorse. These certificates are issued through academic centres or through companies’ internal welding qualification tests. These certificates can ONLY be re-issued through the original issuing organisation or company.

Please contact the company or organisation on your certificate to obtain a copy.
