Welder/Welding Operator Performance Qualification, WPQ

Welder/Welding Operator Performance Qualification Test Report (WPQTR) is a document that shows that a welder or welding operator is capable of welding according to certain standards. The welder / welding operator is tested by applying various destructive and non-destructive examinations / tests on the welded joint produced by the welder / welding operator. Welding tests and inspections/tests are conducted according to a document of Welding Procedure Specification (WPS).

Qualification of welders is applied according to standards “EN ISO 9606–X (2017): Approval testing of welders – Fusion welding”, “EN ISO 14731 (2019): Welding coordination – Tasks and responsibilities”, and “EN ISO 14732 (2014): Welding personnel – Qualification testing of welding operators and weld setters for mechanized and automatic welding of metallic materials”. EN ISO 9606–X (2017) specifies the requirements for qualification testing of welders for fusion welding of steels. It provides a set of technical rules for a systematic qualification test of the welder and enables such qualifications to be uniformly accepted independently of the type of product, location and examiner or examining body. The others identify the essential welding quality related tasks and responsibilities included in welding coordination. The principle of an assessment according to these documents is that welding coordination personnel need to be competent in the welding-related tasks allocated to them. It is presumed that welding coordination personnel have the necessary education, qualifications and experience and are appointed by the manufacturer. Regulatory documents, application standards and contracts can give specific requirements for welding coordination personnel. Otherwise, it is the responsibility of the manufacturer to determine the requirements to be following these documents.

Welding Procedure Qualification Report, WPQR

WPQR is a document showing that the welded connection produced is suitable for welding method, material group, additional metal, consumable materials etc. according to the relevant standards, necessary destructive/non-destructive examinations and tests are carried out and the results are in the required competence. It is qualifying and approving a preliminary Welding Procedure Specification (pWPS), becoming WPS. It contains all the data required to qualify a pWPS form. Therefore, each WPS document must have a WPQR document that supports it. Briefly, WPS and WPQR are documents that cover all necessary welding parameters, verify and guarantee the welding procedure. For each new welding procedure, a new qualification is required.

As TEKNOLAB®, in our accredited laboratories according to TS EN ISO / IEC 17025 standard, we provide destructive / non-destructive inspection and test services to welder and welding operator certification bodies and welding procedure approval institutions.
