Development Of Welding Procedure

The Critical Role of WPS & PQR in Modern Welding & Fabrication

In today’s fabrication industry, welding procedures (WPS/PQR) are essential for ensuring structural integrity, safety, and client confidence in critical applications like pressure vessels, pipelines, and load-bearing structures.

Why WPS & PQR Matter:

Welding Procedure Specification (WPS) – Defines the approved parameters for welding, including:
- Base metal & filler material grades
- Joint design & tolerances
- Amperage, voltage, travel speed ranges
- Preheat & post-weld heat treatment (if required)
Procedure Qualification Record (PQR) – Validates the WPS through destructive & non-destructive testing (NDT) of weld coupons, ensuring compliance with AS/NZS, AWS, or ISO standards.

A properly qualified WPS/PQR ensures:
✔ Repeatable, high-quality welds
✔ Compliance with industry codes (ASME, ISO 3834, EN 1090)
✔ Enhanced safety in high-risk applications (pressure vessels, bridges, mining equipment)
✔ Reduced defects & rework costs

Welding Supervision

IWQMS-Certified Welding Supervision for Quality Assurance

IWQMS welding supervisors hold AS 1796 Certificate 10, AS 2214, or International Welding Specialist (IWS) qualifications, ensuring strict adherence to welding codes and quality standards. Their supervision covers all critical aspects of the welding process:

Key Responsibilities of IWQMS Welding Supervisors:

Joint Fit-Up & Tolerance Verification – Ensuring proper alignment and gap compliance per WPS requirements.
Material & Consumable Verification – Cross-checking base metal grades, filler wires, and fluxes against qualified WPS.
Preheat & Interpass Temperature Control – Calculating and monitoring to prevent cracking & HAZ defects.
Interpass Cleaning – Removing slag and contaminants between passes for sound weld integrity.
Weld Bead Profiling – Ensuring correct reinforcement and smooth transitions to avoid stress concentrations.
Post-Weld Visual Inspection – Checking for undercut, porosity, cracks, and other discontinuities.
Welding Supervision Report – Documenting compliance for traceability & quality audits.

Why Choose IWQMS-Certified Supervision?

✔ AS/NZS & ISO 3834 Compliance
✔ Defect Prevention in Critical Welds
✔ WPS-Compliant Execution
✔ Enhanced Structural Integrity
✔ Audit-Ready Documentation
