: Focus on edge preparation, fit-up, cleanliness, and alignment.

As a professional in the non-destructive testing (NDT) industry, you're likely familiar with the importance of visual inspection in ensuring the integrity and reliability of materials, components, and systems. One of the most widely recognized and adopted standards for visual inspection is BS EN 970, a British Standard that outlines the requirements and guidelines for visual testing and inspection.

Using the principles of BS EN 970, inspectors must identify the following surface imperfections: Surface cracks (longitudinal or transverse).

: Vernier calipers, spirit levels, and feeler gauges to check for gaps and misalignments. 3. The Three Stages of Inspection

Clear description of any imperfections found, referenced by weld number.

The standard is concise but dense, covering three critical pillars of the inspection process:

BS EN 970 is a British Standard that defines the requirements for visual inspection and testing of materials, components, and systems. The standard is widely adopted across various industries, including aerospace, oil and gas, power generation, and construction. BS EN 970 provides a framework for visual inspection, including the selection of personnel, equipment, and techniques to ensure that inspections are carried out effectively and efficiently.

Even though the document code has changed, the technical requirements for visual inspection remain largely consistent with the original EN 970 framework: CSWIP 3.1: Question with Answer and Explanation – Part 25

: Such as surface cracks or lack of fusion. Surface Cavities : Such as gas pores or craters.

A common point of confusion is that for weld imperfections. It is a method standard, not a quality standard.
