Third Party Witnessing of Welder Qualification and Weld Procedure Qualification

Our welding specialists provide third party witnessing of weld specification, procedure qualification and welder qualifications when you need independent verification.

Where you have a requirement for independent verification that welding has been performed to the required specification, our welding specialists provide third party witnessing of weld procedure qualification and welder qualifications.
  

Certifying welding procedures – Weld Procedure Specification and Weld Procedure Qualification Record:

Many manufacturers need independent approval for their welding procedures – either for compliance with international standards and codes or to comply with project requirements. Our welding specialists understand the codes or standards that are applicable to verify welding procedures and, as part of the third party witnessing process, we can:

  • Create a Weld Procedure Specification (WPS) - a ‘technique’ card that documents how to produce a weld.
  • Carry out non-destructive testing and destructive testing on the weld test piece produced under the WPS in our laboratories. 
  • Verify the weld test piece meets the applicable codes or standards
  • Issue a Weld Procedure Qualification Record (WPQR) for the weld procedure, which qualifies the WPS
      

Certifying welder qualifications – Welder Performance Qualification:

A welder must hold the necessary qualifications to carry out welding. Intertek’s welding specialists will certify the welder to an approved weld procedure by monitoring and assessing the welder during the welding process, and submitting the test piece to the lab for the relevant testing required by the applicable code. The certification of a welder is usually valid for two or three years, after which there would be a requirement for re-certification of their Welder Performance Qualification.  

By using Intertek’s third party witnessing services, you can ensure that your welding procedures and welders are in accordance with statutory legislation and internationally-recognised welding codes; we qualify and certify welding procedures to BS EN ISO 15614  and ASME IX, and welders in accordance with BS EN 287, BS EN IS0 9606, BS 4872 and ASME IX.
  

Company approvals and accreditations:

  • United Kingdom Accreditation Service (UKAS)
  • Rolls Royce Aerospace

We are a SAFED Associate member (The Safety Assessment Federation) and all testing of welds is undertaken in our UKAS (United Kingdom Accreditation Service) accredited laboratory. These accreditations demonstrate our commitment to promoting safety, reducing risk and to quality management.  

Intertek is also certified by a Notified Body to carry out third party witnessing of welding work under the Pressure Equipment Directive (PED) – a mandatory EU product directive for the design and manufacture of pressure equipment with maximum allowable pressure greater than 0.5 bar.
