Welding procedures for your next job
Need a written welding procedure or help with an existing one? PWC prepares and qualifies WPS and PQR for jobs Australia-wide. Send us the job requirements so we can discuss the work needed.
What are WPS and PQR?
A Welding Procedure Specification (WPS) sets out how a weld is to be made. A Procedure Qualification Record (PQR) records the test weld used to support that procedure.
Start with the job requirements
Tell us the material, welding process and standard named in your contract. If you already have a procedure, send that too.
Standards we work to
We prepare and qualify procedures to AS 1554, AS 3992, ASME, ISO, AWS and API.
Send the material grade, thickness, welding process and the standard your customer has requested, and we'll confirm what the job needs.
From review to records
We start by reviewing what your job requires. The agreed work may include preparing the procedure, arranging the required testing and completing the records.
1. Review
Review the job and any existing procedure.
2. Agree
Agree on the procedure and testing needed.
3. Complete
Complete the documents included in the quote.
What's included
We review your drawings and job requirements, prepare the draft procedure and agree the test weld needed to support it. The test weld can be run at your workshop or ours.
You receive the completed WPS, the PQR and the supporting test reports. Mechanical testing is carried out by NATA-accredited laboratories, or in-house where a NATA report isn't required. We explain any work or costs that are quoted separately.
Procedures we've prepared
PWC has prepared and qualified welding procedures for NWEC, Karuah, TTM Engineering and Veolia, among others.
Have a procedure already?
Send it with the new job requirements so we can discuss whether a review is needed. Need it by a particular date? Include your deadline so timing can be agreed before work starts.
Common questions
What’s the difference between a WPS and a PQR?
A Welding Procedure Specification (WPS) sets out how a weld is to be made. A Procedure Qualification Record (PQR) records the test weld that supports that procedure. Most jobs that need a qualified procedure need both.
Which standards do you prepare procedures to?
AS 1554, AS 3992, ASME, ISO, AWS and API. Send the standard your customer has named and we’ll confirm what the job needs.
Where is the test weld done?
At your workshop or at PWC’s own workshop, depending on the job. We agree the location, and who supplies what, before the test.
Who does the mechanical testing?
We work with NATA-accredited laboratories. Where the job doesn’t need a NATA report, we can carry out the testing in-house.
What do I receive at the end?
The completed WPS, the PQR and the supporting test reports. Anything quoted separately is explained upfront.
Can you review a procedure we already have?
Yes. Send it with the new job requirements and we’ll tell you whether it covers the work or needs a new or revised procedure.
