Visual Inspection

|
Visual Inspection is one of the most common Non-Destructive Testing methods used to evaluate the condition or quality of an item. This NDT method is easily carried out, inexpensive and usually doesn't require special equipment. It entails reflected or transmitted light from a test object being imaged with a light-sensitive device, such as the human eye. Such a testing method requires proper vision, good lighting conditions and the knowledge of what exactly to look for. Visual Inspection can be enhanced by various methods of inspection ranging from a low power magnifying glass through to boroscopes. These devices can also be used with television camera systems. Surface preparation can range from wiping with a cloth to blast cleaning and treatment with chemicals to reveal the surface details. NDT Visual Inspection can sometimes identify where a failure is most likely to occur and identify when a failure has started. Visual Inspection is often enhanced by other surface methods of inspection, which can identify flaws that are not easily seen by the naked eye. SGS offers not only Non-Destructive Testing and Inspection services but also NDT Courses which are available regularly at our NDT Training Centre. We can also provide onsite training on request for your NDT personnel. Send us your inquiry on NDT Visual Inspection now. |
