Overview

EN ISO 15607:2019 - Specification and qualification of welding procedures for metallic materials - General rules sets out the general framework for preparing, developing and qualifying welding procedure specifications (WPS) and welding procedure qualification records (WPQR) for metallic materials. Applicable to manual, partly mechanized, fully mechanized and automated welding, the standard defines the rules and qualification routes to ensure welding procedures are suitable for production and consistent with other ISO welding standards.

Key topics and requirements

• WPS / pWPS / WPQR: A preliminary WPS (pWPS) must be prepared and subsequently qualified. Qualification produces a WPQR that records essential and non‑essential variables and qualification ranges.
• Qualification methods: The standard lists permitted methods for qualifying a WPS, including:
  • Welding procedure test (laboratory or production test welds)
  • Qualification based on tested welding consumables
  • Qualification based on previous welding experience
  • Qualification by adoption of a standard welding procedure
  • Pre‑production welding test
• Format and content linkage: ISO 15607 refers to the ISO 15609 series for WPS content and format, ensuring technical consistency across process types (arc, gas, electron beam, laser, laser‑arc hybrid, resistance welding).
• Competence assumption: The document assumes WPSs will be applied by competent welders or operators qualified under relevant standards (e.g., ISO 9606 for welders, ISO 14732 for operators).
• Annexes for implementation:
  • Annex A - details of the series of standards for specification/qualification
  • Annex B - table showing how to use the standards
  • Annex C - flow diagram for developing and qualifying a WPS
• Validity and applicability: Qualification must precede production welding; WPQRs shall include all variables and ranges as required by the applicable part of the ISO 1560x series.

Practical applications

• Use EN ISO 15607:2019 to design and document welding procedures before production, ensuring metallurgical and mechanical performance are controlled where non‑destructive testing is insufficient.
• Apply when introducing new materials, joining technologies (including automated and hybrid processes), or when required by an application or contract standard that mandates a particular qualification route.
• Helpful for quality managers, welding engineers, fabricators, and inspectors to standardize procedure qualification and maintain traceable WPQRs for audits and compliance.

Who uses this standard

• Welding engineers and procedure authors
• Quality and production managers in fabrication and manufacturing
• Certification bodies, inspectors and auditors
• Manufacturers adopting automated or mechanized welding systems
