A PQR stands for Qualification of Welding Operation Mode.
This qualification is carried out by a third party organization of the validity of the welding parameters, the samples are welded in front of an inspector then sent to a laboratory to be subjected to tests (hardness, macroscopy, traction, folding…) in order to validate the operating mode which will be used then to carry out WPS.
The PQR is therefore a document recognizing the reliability of a weld performed according to a WPS subject of qualification and gives satisfactory results to the intended service.
For some companies, the PQR may require special management. Imagine the magnitude of the task when there are multiple welds and many WPS – PQRand that during the course of the project there are possible changes in the parameters of the customer or the standards in force.
A management system established in Excel will show its limits in terms of ergonomics and efficiency when the activity increases. Well-made formulas do not protect against errors and unfortunate modifications, especially when used by several people.
