Visual Inspection (VT)

Of the non-destructive testing methods, the simplest and most easily applied visual inspection method (visual testing, VT). Non-destructive testing methods are applied without damaging the properties of the material being used and without damaging the material. In this respect, visual inspection does not detect the inside of the material, it is only a superficial method. However, many non-destructive testing methods primarily require visual inspection and recording of the findings.

Mainly, the visual inspection method examines discontinuities, noticeable structural defects and details that may adversely affect the quality of the products under inspection and inspection. In these studies, a number of auxiliary optical devices such as magnifiers, endoscopes or videoscopes are used depending on the accessibility of inspection surfaces. But it is not a necessity. Visual inspection or visual inspection is generally performed mechanically and optically.

This method can be applied to all metallic or non-metallic materials. When applying this method, the surface should be able to show the best possible defects. Therefore, it is not desirable to clean the surface before inspection. However, the environment should be bright enough.

The aim of the Regulation on Health and Safety Conditions in the Use of Work Equipment is to regulate the minimum requirements for the health and safety of work equipment used in the workplace. Details of the Annex to the Regulation on Maintenance, Repair and Periodic Inspections (Annex 3) are provided. Accordingly, tanks and tanks containing hazardous liquids, which are corrosive or harmful to health, must be inspected and inspected annually by non-destructive testing methods unless otherwise specified in the relevant standards.

Our company is non-destructive visual inspection services within the framework of inspection services. In these studies, relevant legal regulations, standards and test methods published by local and foreign organizations are complied with. A few standards are based on:

  • TS EN 13018 Non-destructive testing - Visual inspection - General rules
  • TS EN 13927 Nondestructive testing - Visual inspection - Equipment
  • TS EN ISO 17637 Non-destructive testing of fusion welds - Visual inspection of fusion welded joints
  • TS EN ISO 17635 Non-destructive testing of welds - General requirements for metallic materials
  • TS ISO 3058 Nondestructive testing - Visual inspection tools - Selection of low-magnification tools
