Re: [MW:25703] Re: what is pre qualified WPS as per AWS D1.1

Dear Sridhar,

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

To initiate the welding, pWPS required.

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.

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).
