Overview
SIST EN ISO 15611:2024 specifies the requirements for the qualification of welding procedures for metallic materials based on previous welding experience. Developed by CEN and ISO, this international standard provides critical direction for manufacturers seeking to demonstrate welding procedure compliance without conducting new tests, relying instead on demonstrable, documented prior experience. SIST EN ISO 15611:2024 supports organizations in establishing welding procedure qualification in a manner that is both efficient and aligned with ISO 15607 general requirements. The standard applies to metallic materials and covers a wide range of welding processes, offering guidance on documentation, traceability, and the extent of qualification.
Key Topics
SIST EN ISO 15611:2024 addresses several central aspects for the effective qualification of welding procedures:
- Scope and Applicability: Defines how previous welding experience can be used as a basis for welding procedure qualification in accordance with ISO 15607.
- Required Documentation: Details the documentation needed to support claims of previous welding experience, such as test data, manufacturing summaries, or records of component service performance.
- Preliminary Welding Procedure Specifications: Explains the creation and use of preliminary welding procedure specifications (pWPS) as per relevant standards.
- Qualification Process: Outlines steps for confirming that welding procedures comply using past experience, including service history and manufacturing consistency.
- Range of Qualification: Provides the framework for determining the applicability of qualified procedures to similar operations, referencing associated standards for specific processes.
- Welding Procedure Qualification Record (WPQR): Describes the structure, content, and required signatures for a valid WPQR based on documented experience.
Applications
SIST EN ISO 15611:2024 is essential for industries and companies involved in the fabrication and production of welded metallic components and structures. The standard is especially valuable in scenarios where:
- Established Manufacturing Experience: Organizations have significant documented experience with specific welding procedures and want to avoid redundant testing.
- Time and Cost Efficiency: Manufacturers seek faster and more economical routes to procedure qualification compared to conducting additional qualification tests.
- Regulatory and Client Compliance: Demonstrates weld quality and procedure conformity to regulators or clients without new destructive or non-destructive test programs.
- Audit and Traceability: Supports robust traceability through systematic documentation of previous welding experience and quality records.
- Continued Production: Helps maintain continuity for ongoing manufacturing, especially after updates to procedures or standards.
Typical user sectors include structural engineering, pressure equipment manufacturing, automotive, shipbuilding, and other fields where metallic welds play a critical role in safety and performance.
Related Standards
SIST EN ISO 15611:2024 references and works in conjunction with several foundational welding standards, including:
- ISO 15607: General rules for specification and qualification of welding procedures for metallic materials.
- ISO 14555: Arc stud welding of metallic materials - qualification guidelines.
- ISO 15609 (all parts): Covers the preparation of welding procedure specifications (WPS).
