What is ISO 17639 - Macroscopic and microscopic examination of welds about?
ISO 17639 helps its users to perform tests that reveal the macroscopic or microscopic features of a welded joint.
ISO 17639 is an international standard that specifies gives recommendations for specimen preparation, test procedures, and their main objectives for macroscopic and microscopic examination.
Who is ISO 17639 - Macroscopic and microscopic examination of welds for?
ISO 17639 on macroscopic and microscopic examination of welds useful for:
Welding services
Testing houses and labs for metallic materials
Suppliers of metallic components
Quality assurance services
Why should you use ISO 17639 - Macroscopic and microscopic examination of welds ?
Destructive weld testing involves the physical destruction of the completed weld in order to evaluate its characteristics. This method of testing is used frequently for a number of applications.
ISO 17639 helps you to assess the structure (including grain structure, morphology and orientation, precipitates and inclusions) independently and/or in relation to various cracks and cavities. ISO 17639 gives guidance on the assessment of features that can be detected by macroscopic and microscopic examination.
Overall, the guidance of ISO 17639 enables you to identify the macroscopic and microscopic features of welded joints.
