Visual inspection using endoscopes and borescopes
Visual inspection with endoscopes and borescopes is an optical inspection of hard-to-reach cavities and internal structures. It enables visual assessment of hidden weld roots.
Physical-Chemical Mechanism of Action
Endoscopes and borescopes use optical lenses or light guide systems to direct light into small cavities. The introduced light is reflected off the material surface and returned, making hidden structures visible.
Metallurgical Relevance & Risks in Welding
This method is especially important for inspecting weld roots in complex components because it provides direct information on the quality and integrity of the weld. Missing or defective roots can lead to cracks and deformations, compromising component safety.
Workshop Practice & Instructions
Use high-quality endoscopes or borescopes with high resolution and sufficient light output. Make sure the interior is clean and free of interfering factors like dirt or moisture. Take images or videos as needed for detailed analysis.
