Visual Endoscopic Inspection
Visual endoscopy inspection is an optical inspection method that visually examines inaccessible cavities and internal surfaces. It enables direct detection of corrosion damage or contamination.
Physical-Chemical Working Principle
Visual endoscopy uses a flexible or rigid optical camera that is fed through a tube into hard-to-reach areas. The camera sends images back to a display device, making the inside of the inspected objects visible.
Metallurgical Relevance & Welding Risks
Visual endoscopy is especially important in weld inspection to spot corrosion damage or contamination inside pipes, pipelines, or complex components. Missing or inaccurate inspections can lead to safety risks and further damage over time.
Workshop Practice & Procedures
For visual endoscopy testing, you need a qualified borescope and the right image analysis equipment. Perform the inspection under clean conditions to make sure no contaminants are introduced. Pick the right type of scope depending on the geometry and size of the area being checked. Analyze the images carefully to identify any corrosion damage or contamination.
