What is a PQR in welding?

A Procedure Qualification Record is a crucial document in welding that outlines the specific parameters and results of a welding procedure test. It serves as evidence that the welding process and parameters have been qualified to meet specified standards, ensuring both the quality and reliability of the welds produced in actual applications.

The PQR provides essential information about the welding materials, techniques employed, and the test results, including mechanical properties. This document ensures that the welding process can consistently produce welds that meet the required standards for strength and integrity, ultimately contributing to the safety and performance of welded structures in various industries.

Understanding the significance of a PQR is vital, as it confirms that the welding procedures are adequately documented, validated, and can withstand scrutiny in regulatory or quality assurance processes.
