Procedure Qualification Record (PQR)

A Procedure Qualification Record (PQR) is a formal document that captures all welding parameters and results from the qualification of a welding procedure. It serves as a factual record of the welding conditions used to produce a test coupon, along with the results of the required mechanical or toughness testing. All essential variables, including specified ranges, must be documented, especially when notch toughness is a qualification requirement, in which case supplementary essential variables must also be included.

The PQR must be certified for accuracy by the responsible party and cannot be subcontracted. When multiple welding processes are employed, the weld deposit thickness and filler metal used for each process must be recorded. Ensure Welding Excellence with Certified Professionals

SV NDT Services specializes in Welder Performance Qualification (WPQ) services that verify a welder's skill and capability to perform high-quality welds according to industry codes and project specifications. We aim to help businesses across the construction, manufacturing, energy, and industrial sectors meet safety, quality, and regulatory demands by certifying their welders through rigorous performance testing.

Welder Performance Qualification (WPQ)

What is Welder Performance Qualification?

Welder performance qualification is a formal evaluation process that ensures a welder can deposit sound welds using specific materials, positions, processes, and joint configurations. It’s a requirement in industries where weld integrity is critical for safety, structural soundness, and code compliance.

The test is typically performed on test coupons and follows:

• Welders - EN ISO 9606 procedure.

• Welding operators - EN ISO 14732

Why Welder Qualification Matters

Welder performance qualification is more than a compliance requirement—it’s a critical step in ensuring the integrity and safety of welded structures. Qualified welders reduce the risk of failures, increase productivity, and boost your reputation for delivering quality workmanship.
