This document is a report on its contents during the experiment to know the specification welding the most appropriate for a process welding for one connection / joint, which includes the heat input, flow, type of filler, welding position, weld layer, etc.. Results welding is then conducted to test mekanical known where the most good.

Data from the PQR data processed by following the rules of the code, especially the problem of tolerance parameters parameter welding. Results from the processed data is transferred in a summary of disebit WPS.

WPS: Welding Procedure Qualification

The results of PQR is most appropriate for a joint. Contents more or less the same as PQR. WPS is used as a guide welder during welding.

WPS is a document that contains instructions how to do production welding in the field. Parameter contains the parameters on the process and make welding Technik. WPS made from data taken at the time of running test coupon. Collection of data on the running time to test coupon, NDT and mechanical test is called the PQR.

So PQR bus follow of material data (certificate), Consumable, welding process (amp, volt, HI, travel speed, polarity), pass the NDT records, record pass DT.
