ISO 15614 Welding Procedure Qualification (WPS/PQR)

Scope

ISO 15614 is an international standard for welding procedure qualification issued by ISO, applicable to all welding manufacturing enterprises. It serves as a core requirement for welding process control in quality certification systems such as ISO 3834, EN 1090, and PED.

[Certification Content]

• Develop project-specific pWPS (Preliminary Welding Procedure Specification).

• Perform actual welding operations covering joint type, base material, filler material and welding parameters.

• Conduct non-destructive and destructive tests on test plates (e.g., tensile, bending, impact and metallographic tests).

• Generate PQR (Procedure Qualification Report) and file for archiving.

• Create production-oriented WPS (Welding Procedure Specification) based on approved PQR.

• Applicable to multiple welding processes including SMAW, GMAW, GTAW(TIG), SAW and more.

[Certification Process]

• Define welding requirements and applicable standard scope (e.g., ISO 15614-1, -2).

• Prepare test plates and perform welding per pWPS parameters.

• Commission laboratory testing covering mechanical property tests and metallographic evaluation.

• Finalize and archive PQR documentation.

• Develop production WPS accordingly.

• Documents available for EN 1090 / ISO 3834 / PED audits or on-site production use.

[Allmark Advantages]

• Provide compatibility consulting for multiple standards (ISO, AISC, AWS, etc.).

• Synchronize welder qualification and WPS development to shorten certification timelines.

• Support customized process window parameter expansion to reduce re-certification costs.

• Collaborate with authorized laboratories for full-scope testing to ensure authoritative results.

[Why Choose ISO 15614]

• Provides standardized basis for on-site welding quality control.

• Establishes a welding procedure system meeting international project requirements.

• Fulfills foundational requirements for audits under EN 1090, ISO 3834, PED, and other systems.

• Enhances welding consistency, traceability, and product stability.
