What is WPS PQR and WPQ?
Here’s the translation. WPS – Welding Procedure Specifications. PQR – Procedure Qualification Records, and. WQT / WPQ – Welder Qualification Test / Welder Performance Qualifications.
What is meant by WPQ in welding?
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.

How do you do WPS and PQR?

What Pqr means?
Procedure Qualification Record
The procedures for creating and testing the sample welds, as well as the final results, are documented on a Procedure Qualification Record, or PQR. In short, a PQR serves as evidence that a given WPS can, in fact, be used to produce an acceptable weld.
How do you qualify for PQR?
After completion of welding and heat treatment (if needed), you need to send the test specimen to the metallurgical lab for mechanical testing. For any PQR, normally two tension tests, two root face bend test and two face bend test is required. The acceptance criteria have been provided in the ASME Code Section IX.

Is it possible to qualify welder during WPQ?
The WPQ record indicates the ability of the welder or welding operator to deposit sound weld metal. The WPQ can be qualified by either radiography or ultrasonic testing; alternatively it can also be qualified by mechanical testing.
What is a PQR?
A Procedure Qualification Record (PQR) is the record of the actual weld test parameters used.It is the founding document as far as procedures are concerned and is used to produce welding procedure specification sheets (WPS) for production welds.
