Overview

ISO 15611:2024, titled "Specification and qualification of welding procedures for metallic materials - Qualification based on previous welding experience," is an international standard published by ISO. This standard provides detailed guidance on qualifying welding procedures by leveraging documented previous welding experience. It supports manufacturers and fabricators who have accumulated extensive welding data through production and service performance, enabling them to certify welding procedures efficiently while ensuring quality and safety.

This second edition replaces ISO 15611:2003 with updated references, revised clauses, and streamlined content. It complements ISO 15607 by explaining specific requirements and qualification ranges related to prior experience-based welding procedure approval. The standard can be restricted or supplemented by specific application standards or specifications.

Key Topics

  • Preliminary Welding Procedure Specification (pWPS): ISO 15611 mandates the preparation of a pWPS as the basis for qualification. This specification must define the welding parameters and comply with standards such as ISO 14555 (arc stud welding), ISO 15609 series (general welding procedures), ISO 15620 (friction welding), ISO 18785-4, and ISO 25239-4 (friction stir welding of aluminium).

  • Qualification Criteria: Procedure qualification requires submission of a pWPS along with documented evidence of previous welding experience. This documentation includes test data (destructive, nondestructive, leak, or pressure tests) and manufacturing records or service history confirming consistent, satisfactory weld performance.

  • Documented Welding Experience: Experience must be traceable via records showing at least one year of welding manufacturing or a service period generally considered to be five years, unless otherwise specified. This ensures the weld procedures are validated through real-world application and performance.

  • Range of Qualification: The extent to which a welding procedure is qualified derives from related standards:

    • ISO 15614 series – fusion welding
    • ISO 14555 – arc stud welding
    • ISO 15620 – friction welding
    • ISO 25239-4 – friction stir welding of aluminium
    • ISO 18785-4 – friction stir spot welding of aluminium
  • Welding Procedure Qualification Record (WPQR): The WPQR consolidates the pWPS and documented previous experience. It must be comprehensive, including all relevant welding parameters, and signed by an authorized examiner or body.

Applications

ISO 15611:2024 is crucial for industries where welding quality is fundamental, such as:

  • Manufacturing and Fabrication: Enables efficient qualification of welding procedures based on proven experience, reducing the need for repetitive testing.
  • Construction and Infrastructure: Supports durable and reliable welded joint certification in structural steelwork and piping.
  • Automotive and Aerospace: Facilitates qualification of weld processes involved in critical, high-performance components.
  • Energy Sector: Assists qualification of welding procedures applied to power plants, oil and gas pipelines, and renewable energy structures.
  • Metalworking Industries: Useful for companies engaged in friction and arc stud welding requiring compliance with international standards.

Using prior welding experience for qualification streamlines certification while maintaining strict quality control, helping organizations save time and costs without compromising safety.

Related Standards

ISO 15611 is part of a comprehensive series on welding procedure specifications and qualifications, including:

  • ISO 15607: General rules for specification and qualification of welding procedures.
  • ISO 15609 series: Detailed welding procedure specifications for various welding processes.
  • ISO 15614 series: Welding procedure tests and qualifications for fusion welding.
  • ISO 14555: Arc stud welding of metallic materials.
  • ISO 15620: Friction welding specifications.
  • ISO 25239-4: Friction stir welding of aluminium – Specification and qualification.
  • ISO 18785-4: Friction stir spot welding of aluminium – Specification and qualification.

Together, these standards ensure harmonized approaches worldwide for welding procedure specification, qualification, and quality management.


By adhering to ISO 15611:2024, organizations can confidently validate welding procedures based on extensive prior experience, fostering safer and more cost-effective welding process management aligned with international best practices.
