SIST EN ISO 15614-11:2026 PDF

Overview

SIST EN ISO 15614-11:2026 establishes the requirements for the specification and qualification of welding procedures for metallic materials, focusing specifically on electron and laser beam welding. The standard sets out the methodology for the qualification testing of welding procedure specifications (WPSs), ensuring that both new fabrications and repair work involving metallic components meet stringent quality and safety standards.

This standard is relevant for a wide range of metallic materials, irrespective of shape, thickness, manufacturing method (such as rolling, forging, casting, or sintering), or heat treatment. Developed by SIST and aligned with the latest international guidelines, SIST EN ISO 15614-11:2026 supersedes previous editions and harmonizes European (EN) and ISO requirements for welding process qualification.

Keywords: electron beam welding, laser beam welding, welding procedures, metallic materials, welding qualification, welding standards, WPS qualification

Key Topics

• Qualification Testing Requirements: Details the process for qualifying welding procedure specifications for both electron beam and laser beam welding, including preparation and documentation standards.

• Scope of Application: Applies to most metallic materials regardless of component geometry, thickness, or manufacturing process, covering both production and repair welding activities.

• Standardized Test Pieces: Specifies the preparation, dimensions, and configuration of representative test pieces for various welding joint types-such as butt welds, T-joints, and lap welds-ensuring accurate simulation of production conditions.

• Examination and Testing Procedures: Stipulates both non-destructive testing (NDT) and destructive testing methods, referencing essential tests like radiographic (RT), ultrasonic (UT), visual testing (VT), tensile, bend, hardness, and metallographic tests.

• Acceptance Criteria: Aligns acceptance levels with ISO 13919-1 and ISO 13919-2, which determine quality levels for imperfections in welded joints for various metals and alloys.

• Documentation and Records: Requires a formal Welding Procedure Qualification Record (WPQR) to document every aspect of the test, ensuring traceability and compliance.

• Alignment With Legislation: Supports compliance with European Pressure Equipment Directive 2014/68/EU, providing presumption of conformity when cited in the Official Journal of the European Union.

Applications

The practical scope of SIST EN ISO 15614-11:2026 spans numerous industries where high-integrity metal welding is mission-critical:

• Aerospace and Automotive: Essential for the manufacture and repair of precision components, ensuring safety and longevity of critical assemblies.

• Pressure Vessels and Pipelines: Facilitates compliance with EU safety directives for pressure equipment and related welded structures.

• General Manufacturing: Applicable to the fabrication or repair of metallic parts across diverse sectors, enhancing reliability where electron or laser beam welding is utilized.

• Research and Development: Supports laboratories and technical departments in validating new welding procedures and materials as part of innovation strategies.

• Quality Assurance: Provides a robust framework for companies seeking third-party certification or internal audit compliance related to welding quality.
