Visual testing of fusion-welded joints in metallic materials.
Drawing number, joint identification numbers, material types, and welding process used (e.g., TIG, MIG, MMA).
BS EN 970 acknowledges that the human element is the most critical component of visual inspection. It mandates that inspectors must: bs en 970 visual inspectionpdf best
The standard recognises that some areas are difficult to access. For these situations, it permits the use of specialised aids:
Whether you are looking for a for historical code compliance, training, or legacy project audits, understanding its structural principles, inspection criteria, and modern standard evolution is critical for quality control engineering. ⚠️ Critical Compliance Note: Standard Status Visual testing of fusion-welded joints in metallic materials
The primary objective of the standard is to provide a structured framework for identifying surface irregularities, geometric non-conformities, and visible defects before they compromise structural integrity.
Verify compliance with welding parameters (voltage, amperage, travel speed). Phase 3: After Welding (Final Inspection) Clean the weld surface entirely of slag and spatter. It mandates that inspectors must: The standard recognises
Visual inspection is the most cost-effective and critical form of Non-Destructive Testing (NDT). BS EN 970 ensures that: Surface imperfections are detected early. Welding parameters are being followed.
Tools like the Hi-Lo gauge, Cambridge gauge, or AWS gauge to measure weld reinforcement height, fillet weld leg length, throat thickness, and root misalignment.
Pocket magnifiers with a magnification factor of x2 to x5 are permitted to closely evaluate suspicious surface anomalies.
Ensure the area is free of rust, oil, and moisture. 2. During Welding Inter-run Cleaning: Verify slag removal between passes.
