Welding Procedure Inspection & Qualification Services
What Is It
Every Sound Weld Starts With a Proven Procedure
A Welding Procedure Specification (WPS) defines how a weld must be made - including process, filler material, preheat, current, travel speed, and post-weld treatment.
IRC verifies the WPS through qualification testing and documents the results in a Procedure Qualification Record (PQR), proving that the procedure delivers the required weld quality and performance.
Our qualification covers:
- WPS & PQR review
- Essential variable verification
- Mechanical testing
- Metallurgical examination
- Non-destructive testing
Why Qualify
Why It’s Worth Getting Right Before Fabrication
Prevents Repeated Defects
Identify procedure-related problems before production begins.
Code Compliance
Qualification aligned with ASME Section IX and applicable project standards.
Defensible Documentation
Complete, third-party-verified WPS/PQR documentation for audits and handover.
Reduced Rework
A proven procedure means fewer rejected welds during fabrication.
How It Works
Our Welding Procedure Qualification Method
WPS & PQR Review
Review essential variables against the applicable code.
Test Coupon Verification
Verify the qualification weld produced under specified parameters.
Mechanical Testing
Tensile, bend and impact testing where required.
Metallurgical Examination
Macro and micro examination to assess weld soundness and HAZ structure.
NDT & Reporting
Radiography, ultrasonic, magnetic particle or dye penetrant testing, followed by complete reporting.
Our Capability
One Lab for the Whole Qualification Package
IRC combines mechanical testing and NDT capabilities under one NABL and IBR-accredited setup. This means your WPS qualification can be completed as one consistent, traceable package instead of being divided between multiple laboratories.
