What is Wpar in welding?
The welding procedure approval record (WPAR) is a record of this weld. If the WPAR is approved by the Examiner, it is used to finalise one or more WPSs which is the basis for the Work Instructions given to the welder. Welding procedure test (BS EN ISO 15614) Approved welding consumable (BS EN ISO 15610)
What is WPQR and WPS?
A Welding Procedure Specification (WPS) is the formal written document describing welding procedures, which provides direction to the welder or welding operators for making sound and quality production welds as per the code requirements . A WPS is supported by a Procedure Qualification Record (PQR or WPQR).
What is difference between PQR and WPQR?
WPS serves as a blueprint for a written instruction or guide on how to create a welded product based on a certain standard and quality. Meanwhile, PQR is a document that checks whether the standard is being followed by inspecting and answering the document regarding specific areas and tests.

Welder Performance Qualifications
Welder Performance Qualifications (WPQ’s) can be thought of as “what was done by a specific welder and what that qualifies the welder to” regarding welding. There will typically be at least one WPQ for every PQR. Generally, there will be more WPQ’s than any other document type.
