Position light sources to create shadows over surface breaks, making cracks easier to spot.
The most authoritative document is (the latest update).
Check for visible cracking, undercut, or surface porosity before the next layer is deposited.
Visual testing of fusion-welded joints in metallic materials.
For a more detailed guide on BS EN 970 visual inspection, you can download a PDF copy of the standard from the British Standards Institution (BSI) website or other reputable sources.
Visual testing under this standard is primarily performed in the . However, the standard allows for inspections at multiple intervals throughout the manufacturing process based on contractual or application mandates.
: The angle of the eye relative to the weld surface should not be less than 30 degrees Personnel Vision
Date of examination, stage of inspection (before, during, or after), and ambient lighting levels.
Verify alignment (hi-lo) and ensure tack welds are clean, uncracked, and properly profiled. Phase 2: During Welding (In-Process) This phase is critical for multi-pass welds.
