Welding procedure qualification.

How do you show that your welders are competent?

What is it?

Welding procedure qualification tests are designed to show independent proof that if your welders follow a given set of parameters, then they will produce a joint that meets the design requirements. If procedures are followed, then the joint will also have the desired levels of weld quality and mechanical properties.

This indepenent validation is required by a code of construction, a regulation, or even by a contract with the end user.  

Even beyond an external requirement, code compliant welding procedures are not only important for a fabricator's consistency, but also for the safety of their welders. Independent witness and review can also help refine the procedures to make sure safety-critical assets are welded to the proper level of quality.

What we do.

As an independent, accredited and globally recognised third-party inspection agency, LR can certify your welding procedures in accordance with many codes and standards.

In our 250+ years of history, we reviewed some of the first welding procedures used onboard steel ships. This has led to a wealth of knowledge that our customers use not only to refine their procedures, but also show their stakeholders their commitment to quality.

As an ASME Authorised Inspection Agency and EU Notified Body for permanent joining approval, LR has the expertise to assist you in the qualification of your welding procedures according to national, European and internationally recognised standards. This includes:

  • ASME Section IX
  • AWS
  • BS 4515

Our passion is to deliver a service of quality, integrity and a safety ethos, coupled with a technical wealth of experience, knowledge and professional academics; which in turn provides confidence for you and your stakeholders throughout the whole service.
