Prequalified welding procedure specification includes a weld joint specified in a governing code that does not require validation of welding parameters through the performance of a procedure qualification test. So, a prequalified WPS does not need a supporting Procedure Qualification test Record (PQR).

It means if you have already qualified a procedure for similar P nos,

say, as per ASME sec IX or any code, you can refer it in your new

WPS if done with AWS D 1.1 for same P nos. No need to do a PQR

for the new WPS.

Dear Sridhar,

Here we are talking about Pre-Qualified WPS i.e..pWPS.

To initiate the welding, pWPS required.

Prequalfied wps means you can use welding processes, base metal, filler metal and other welding variables as given in AWS D1.1 only..you can't deviate otherwise you need to qualify it.

Hope to have your understanding on above
Aly
