Visual Testing (VT) Practice Exam

What type of examination would use a fiberoptic borescope most effectively?

1. Examination of external weld surfaces.

2. Inspection of internal components in tight spaces.

3. General visual inspection of structural integrity.

4. Measurement of large surface areas.

The correct answer is: Inspection of internal components in tight spaces.

The use of a fiberoptic borescope is optimized for the inspection of internal components in tight spaces. This specialized tool is designed to provide a clear view into areas that are otherwise difficult to access, such as the insides of engines, pipes, or other confined spaces. The borescope utilizes a flexible tube equipped with a camera and light source, allowing for detailed observation without the need for disassembling the entire structure. This capability is particularly valuable in many industrial applications, where the integrity of internal components is critical and potential issues must be identified swiftly and accurately. By allowing inspectors to see into tight or hard-to-reach areas, the fiberoptic borescope enhances the thoroughness and effectiveness of visual inspections. In contrast, options like examining external weld surfaces or performing general structural integrity inspections typically do not require the use of such specialized equipment, as these can often be accomplished through simpler visual inspection methods or by utilizing other types of measuring tools. Measurement of large surface areas also falls outside the typical applications of a borescope, which is specifically intended for focused, detailed internal inspections rather than broad measurements.
