Inspection isn't just a final check; it's a process that happens at three critical points:
An inspection is not legally complete until it is documented. Under the standard guidelines, a professional visual inspection report must feature the following data blocks:
Stringent (High-stress applications like aerospace or nuclear). Level C: Intermediate (General structural steelwork). Level D: Moderate (Low-load, non-critical applications). 5. Identifying the Best "BS EN 970 PDF" Resources

The inspector's eye must be within 300 mm (12 inches) of the weld surface.
Identified by looking down the weld toe line under angled light. Too much reinforcement height on the face of the weld. Measured using a bridge cam or fillet gauge. Surface Porosity

BS EN 970 remains a pillar of industrial welding knowledge. By ensuring that inspectors operate under ideal lighting conditions, utilize calibrated measuring gauges, and systematically evaluate joints before, during, and after welding, fabricators can prevent catastrophic structural failures long before more expensive NDT methods (like Radiography or Ultrasonic Testing) are even deployed.
Visual inspection is the most fundamental, cost-effective, and critical non-destructive testing (NDT) method in welding engineering. Before employing expensive radiography or ultrasonic testing, a thorough visual examination can detect up to 80% of surface defects. For decades, ("Non-destructive examination of fusion welds — Visual examination") served as the backbone standard for this process across Europe and international supply chains.
The standard specifies that inspection must be performed with the naked eye or with the aid of optical instruments.
