What is ISO 17637-Visual testing of fusion-welded joints about?
ISO 17637 is an International Standard that specifies the visual testing of fusion welds in metallic materials. It may also be applied to visual testing of the joint prior to welding.
Note: ISO 1763 does not define the extent of visual testing. However, this should be determined in advance, e.g. by reference to an application or product standard.
Who is ISO 17637- Visual testing of fusion-welded joints for?
ISO 17637 on non-destructive testing of welds is applicable to:
- Fusion-welded joint manufacturers
- Inspection authorities in various sectors such as construction, automotive, general engineering, aerospace, and marine
- Authorised training and qualification bodies
- Certification bodies
Why should you use ISO 17637- Visual testing of fusion-welded joints?
The visual testing method allows detecting discontinuities and identifying the defects in fusion welded joints. Visual testing is usually performed with the naked eye or with magnifying glasses.
ISO 17637 specifies the visual testing of fusion welds in metallic materials. It may also be applied to visual testing of the joint prior to welding.
ISO 17637 ensures that visual testing of fusion welds in metallic materials is uniform and repeatable, irrespective of new processes, revised standard practices, newly developed equipment or changes to the materials used. ISO 17637 can thus help you improve the weld quality by precise and efficient visual testing of fusion-welded joints.
