Efficient and Effective Nondestructive Analysis
As the name might imply, visual inspection is the most fundamental of nondestructive testing methods. It often requires nothing more than sufficient light to illuminate the material surface being examined and the well-trained eyes of an experienced inspector (sometimes assisted by a magnification lens, or lens system that provide easier access to remote surfaces). In fact, a number of commonly used nondestructive testing methods simply represent the application of advanced visualization technologies to make flaws and imperfections more visible to the eyes of an inspector.
Visual inspection techniques are generally used to evaluate the surface condition of a material under evaluation, and to search for evidence of cracks or leaks. Visual inspection can also be used to assess the shape of critical components, or the alignment of surfaces of adjacent materials and parts. Finally, visual inspection techniques can be an efficient and cost-effective method for examining interior surfaces of complex equipment.
Despite its apparent simplicity, visual inspection requires the knowledge and experience of trained professionals. TÜV SÜD inspection professionals are certified to the American Society of Nondestructive Testing (ASNT) Level III and Level II requirements, and are skilled in every aspect of NDT inspection and testing techniques. To provide our customers with maximum flexibility, we can conduct visual inspections and other types of NDT testing at customer site locations and in the field as required, as well as in our state-of-the-art laboratories and testing facilities.
