Pre-Qualified Welding Procedure Specification

Pre-Qualified Welding Procedure Specification

Pre-Qualified Welding Procedure Specification

Where do I look for getting the information that would say that Pre-qualified WPS does not require a PQR?

RE: Pre-Qualified Welding Procedure Specification

Assuming you are using section IX, since this is the ASME forum, look at Article V.  It describes the requirements for using a SWPS. (Standard Welding Procedure)

RE: Pre-Qualified Welding Procedure Specification

Sorry to disagree,   Use of prequalified weld procedures is controlled by the individual contruction codes only which details the extra steps you may have to take to use them.  ASME VIII discusses it in UW-28 (d), section I in PW-1.2, NBIC in RC-1092, etc....

RE: Pre-Qualified Welding Procedure Specification

In addition, the statement of "no PQR required" in not found in any of the Codes to my knowledge...  The scope section of the procedure itself talks breifly about how the procedure was developed including a reference to a PQR.  What is driving your question...has someone asked to see a PQR?

RE: Pre-Qualified Welding Procedure Specification

when the change in the qualified WPS is limited only to non-essential variables then all that is needed is to simply referenced the previous pqr to the new wps. the new wps does not require requalification.

RE: Pre-Qualified Welding Procedure Specification

No deviation from essential or NON-essential variables are permitted when using standard WPS's.

RE: Pre-Qualified Welding Procedure Specification

The SWPS is typically a generic procedure that has been qualified thousands of times, for this reason the term prequalified means a procedure qualification record is not necessary for that individual procedure. The SWPS is joint effort of the AWS and ANSI for more info look at the AWS B2.1 Standard for welding procedure and performance qualification. Hope this helps.

RE: Pre-Qualified Welding Procedure Specification

Is there a word template that anyone has to create a WPS?

RE: Pre-Qualified Welding Procedure Specification

There are several sources for computer programs and templates.  I'd be happy to refer you outside this forum

RE: Pre-Qualified Welding Procedure Specification

If you have MS Access, I can supply you with a simple program for filling out a WPS, Printing it, and printing out a WPS Index. No cost.

Also a company called C-Spec has an great program with a free demo. If you just want a "Word" form I have one or can make another easily.

Let me know if you need any other assistance.
