: Magnifying lenses (typically 2x to 5x) and specialized weld gauges are permitted to verify dimensions and defect sizes. Stages of Visual Inspection
: For direct visual inspection, the inspector's eye must be within 600 mm (approx. 24 inches) of the weld surface. Viewing Angle bs en 970 visual inspectionpdf best
Visual testing of fusion-welded joints in metallic materials.
The weld must be completely clean, free of slag, spatter, and protective coatings. Purchasing from BSI costs approximately , depending on
An irregular groove melted into the base metal at the weld toe.
A common point of confusion is that for weld imperfections. It is a method standard, not a quality standard. 24 inches) of the weld surface
BS EN 970 remains foundational to welding inspection practice. It standardized European visual testing and continues to influence contract requirements and legacy system audits. While modern quality systems demand ISO 17637, understanding BS EN 970 provides essential context for interpreting historical fabrication requirements and the development of visual inspection methods.
The ultimate guide to BS EN 970 provides critical insights into the standard for the visual inspection of fusion welds. While BS EN ISO 17637 has officially superseded this standard, many legacy projects, specifications, and quality manuals still directly reference BS EN 970. Understanding its core requirements ensures compliance and maintains high welding quality. Overview of BS EN 970
