Details the inspection steps across different project phases.
Visual inspection is an ongoing quality assurance process, not just a final check. ISO 17637 segments testing into three distinct execution stages. Phase 1: Before Welding (Joint Preparation) Before any arc is struck, the inspector must verify:
: 350 lux is the absolute minimum requirement for the surface being inspected. Recommended iso 17637 pdf
The client was a cryogenics firm building a storage tank for lunar-bound fuel cells. One bad weld, one hairline crack missed, and the whole thing would turn into a three-million-dollar geyser of liquid hydrogen. The contract specified compliance with ISO 17637, the international bible for visual testing of fusion-welded joints.

provides guidelines for the use of computed radiography (CR) for non-destructive testing. CR is a digital radiography technique that uses a photostimulable phosphor plate to capture and store radiographic images.
Using pirated, unauthorized, or outdated versions of the ISO 17637 PDF downloaded from unverified document-sharing forums introduces severe corporate liability. Outdated copies may lack recent amendments regarding tool calibration or inspector vision testing regulations, which can result in failed quality audits or costly project reworks.

Once the weld is complete and cooled down to ambient temperature, the final evaluation takes place:
Checking the profile, width, and height of the reinforcement.
She pulled out her illuminated magnifier (7×, as ISO 17637 required for fine surface evaluation) and started at the 12 o’clock position. For two hours, she moved clockwise, millimeter by millimeter.
Inspectors must have their vision checked regularly. The standard requires that personnel performing the test have adequate near-surface vision, usually verified by checking their ability to read Jaeger Number 1 or Times Roman 4.5-point font at a distance of not less than 30 cm. 2.
