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 WPS (Welding Procedure Specification).

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

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

• Generate and archive PQR (Procedure Qualification Report) for guiding on-site production.

• Applicable to various welding methods, including manual, arc, TIG, and submerged arc welding.

[Certification Process]

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

• Prepare test plates and perform welding according to WPS parameters.

• Commission laboratory testing for mechanical properties and metallographic analysis.

• Archive PQR documentation.

• Submit for EN 1090/ISO 3834/PED audits or on-site production applications.

[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.
