Abstract
Overview
EN ISO 17639:2022 (ISO 17639:2022) provides recommendations for destructive tests on welds in metallic materials, focusing on macroscopic and microscopic examination of welds. The standard defines specimen preparation, test procedures and the main objectives for revealing weld geometry, defects and microstructural features. It supersedes the 2013 edition and is published by CEN/ISO for harmonized national implementation.
Key topics and technical requirements
- Scope and purpose: Guidance for preparing and examining weld sections to assess structure (grain structure, morphology, precipitates, inclusions) and detect cracks, cavities and other defects.
- Examination definitions:
- Macroscopic examination: visual or low magnification (generally
