What is different WPS and PQR ??

Question

Accepted Answer

WPS and PQR are both related to welding procedures, but they serve different purposes.

WPS stands for Welding Procedure Specification, which outlines the specific welding parameters and techniques to be used for a particular welding job.
PQR stands for Procedure Qualification Record, which is a document that verifies the welder's ability to produce welds meeting the required standards.
WPS is prepared before the welding job and provides instructions for welders, while PQR is created after the welding job to demonstrate compliance with the specified procedures.
WPS includes details like welding process, filler material, preheat temperature, etc., while PQR includes test results, such as mechanical properties and visual inspection records.
WPS is used as a reference during welding, while PQR is used for documentation and quality assurance purposes.
