Non-destructive testing (NDT) is an analytical technique used to detect flaws or imperfections in materials without causing any damage to the object being tested. This is a critical feature in industries such as aerospace and nuclear power, where the cost of failure is very high. There are many different applications for non-destructive testing, and several different techniques can be used depending on the material being tested and the type of problem being looked for. Traditional non-destructive testing generally uses sound, light, electricity, magnetism and other methods, all of which have varying degrees of limitations.
As a new type of tool, industrial endoscopes install tiny lenses on long tubes to transmit internal images and provide data reference for inspection personnel. It has become an important auxiliary tool in the non-destructive testing process. The advantage is the ability to inspect complex shapes and structures, and the flexibility of the products allows them to be inserted into tight spaces and bent around corners. Endoscopes also enable remote inspection, reducing the need to disassemble or disassemble components. They allow detailed inspection of components without causing damage or disassembly. As a result, endoscopic products are widely used in various industries, including automotive, aerospace, piping and manufacturing. Their flexibility and ability to inspect hard-to-reach areas make them an important tool for any inspection programme.
