Personnel should be trained and certified in accordance with or an equivalent standard.
Surface white light must be a minimum of 350 lx , though 500 lx is recommended.
Scanning for undercut, overlap, surface porosity, stray arcs, and surface cracks.

The standard outlines specific parameters to ensure that the inspection environment and the examiner’s techniques do not introduce variables that could lead to missed defects or false rejections. It covers:
She grabbed her hard hat. “We’re going old school.”
The inspector’s eyes must be within 600 mm (approx. 24 inches) of the surface being examined.
Verifying that the weld conforms to the original Welding Procedure Specification (WPS), including the depth and shape of any gouging. 4. Documentation and Records Personnel should be trained and certified in accordance
Ensuring compliance with thermal constraints. Phase 3: After Welding (Final Inspection)
Conclusive statement marking the weld as Acceptable or Rejected based on the referenced quality standard.
The standard outlines specific technical requirements to ensure that visual inspections are reliable and standardized across the industry. Testing Conditions & Environment Illuminance : A minimum surface light level of is required, though is strongly recommended for better visibility. : The inspector's eye should ideally be within of the surface, with a viewing angle not less than 30 raised to the composed with power Personnel Qualifications
ISO 17637 does not mandate a single certification path, but it strongly emphasizes that visual testing must be performed by a . The standard references ISO 9712 (NDT personnel qualification) as the recommended certification for visual inspectors. In practice, this requires: And right now, the Trans-Continental Shipyard was hiding
: Checking edge preparation, fit-up, and cleanliness before welding starts.
Ensuring throat thickness, leg lengths, and weld reinforcement profiles meet engineering specifications. 7. Documentation and Reporting
