What is the main purpose of using a bore scope in visual inspection?

To measure external dimensions of pipes.
To detect surface cracks on materials.
To examine internal features of components.
To ensure proper alignment of welding equipment.

The correct answer is: To examine internal features of components.

The main purpose of using a bore scope in visual inspection is to examine internal features of components. Bore scopes are specialized tools designed to provide visibility into previously inaccessible areas of machinery, systems, or assemblies without requiring disassembly. This capability is crucial for assessing the condition of internal components, such as engines, pipes, and other structures, where visual access is limited. Through the use of a bore scope, inspectors can identify issues such as wear, corrosion, blockages, or misalignments within these components, ensuring that they function properly. The ability to observe intricate internal details facilitates preventive maintenance and helps in diagnosing problems before they lead to significant failures. Therefore, its primary application aligns directly with the need to inspect and assess internal structures effectively.
