"Clause 6.2," Elias countered, scrolling down the PDF. "Lighting conditions must be sufficient to identify such shadows. You claim the lights were working? Then this isn't a shadow. It's a crater crack."
Inspecting the bevel angle, root gap, and cleanliness before welding.
Verify mandatory lighting levels for inspection environments. iso 17637 pdf
Checking joint preparation, cleanliness, and assembly.
ISO 17637:2016 establishes international standards for the non-destructive visual testing (VT) of fusion-welded joints in metallic materials, outlining requirements for inspection before, during, and after welding. The standard specifies key conditions, including a minimum 350 lx illumination, a maximum viewing distance of 600 mm, and a minimum viewing angle of 30° to the surface, while requiring compliance with WPS specifications.
