Qualify the Procedure Before the
Procedure Gets Tested

PQR plates through mechanicals and paperwork — CWB and ASME IX, in our own Edmonton lab.

Weld Procedure Qualification (WPS/PQR) Testing

A welding procedure isn't qualified because it looks right — it's qualified because a test plate welded to it survived the mechanical testing its code demands. CIC's Edmonton lab runs weld procedure qualification end to end: test plate coordination, specimen machining, bends, tensiles and macros, and the PQR documentation that supports your WPS under CWB requirements or ASME Section IX.

What a PQR Involves at CIC

  • Test plan — essential variables, positions and test matrix mapped against the governing code before an arc strikes

  • Plate welding — at your shop with parameters recorded, or coordinated at our facility

  • Specimen machining and testing — tensiles, guided bends, macro-etch and hardness as the code and service require

  • Documentation — PQR records tied to test results, supporting the WPS your production runs under

Procedure Development, Not Just Pass/Fail

When a procedure fails qualification, a bare 'fail' report leaves you guessing at parameters. Because the testing and the metallurgy live in the same building, CIC can tell you what the failed specimen says — hardness spike in the HAZ, incomplete fusion at the root, ferrite out of range — and what to change before the next plate. That's the difference between a testing vendor and a qualification partner.

Pairs Naturally With Welder Qualification

A new WPS usually means welders qualifying to it. Procedure and performance qualification run through the same lab, same visit where practical — one scheduling conversation covers both, and production starts sooner.

Frequently Asked Questions

What's the difference between a WPS and a PQR?

The PQR (procedure qualification record) is the evidence — the recorded parameters and test results from the qualification plate. The WPS (welding procedure specification) is the instruction written from that evidence, giving welders their working ranges. The PQR proves; the WPS directs.

When does a procedure need requalification?

When an essential variable changes outside the qualified range — different base material group, thickness range, process, or heat treatment condition, per the governing code's tables. Send us the change you're contemplating and we'll confirm whether it triggers a new plate.
