Visual Inspection

Visual Inspection; It is a so-called method that has been known and practiced for centuries. The biggest advantage of this examination method is that it can get results very cheaply and very quickly compared to others, and the biggest disadvantage is that it requires high experience and experience.

In fact, Visual Inspection is also applied during the application, inspection and interpretation of many NDT methods, but it does not require high investment costs and expensive devices like other methods, Visual Inspection is usually only done with the naked eye in this sector. It also uses auxiliary equipment such as magnifying glass, mirror, gauge and light when necessary.

In Visual Inspection, one of two techniques is applied, namely Direct Visual Inspection and Indirect Visual Inspection, which are explained below. The technique, place, time and quality levels to be applied are decided by our Visual Inspection Level-3 specialist in line with customer demands.


Visual inspection is applied in welded productions before, during and/or after welding, as well as in Forging and Casting productions according to the relevant standards.


a. Direct Visual Inspection:

It is a method of visual testing of a continuous optical path between the observer and the test area. eg. deviceless direct visual inspection or inspection of narrow areas (pipe interiors, gearboxes, heat exchangers, turbines, etc.) where direct eye contact cannot be made with equipment such as mirrors, lenses, endoscopes (boroscopes) or fiberoscopes.


b. Indirect Visual Inspection:

In cases where the conditions described in the Direct Visual Inspection technique cannot be met, this technique is applied. It is the transmission of the image on the examination surface to the eye with assistive devices. eg. videoscope, photography, automated systems and robot use.
