Non-destructive inspection is a method of testing and evaluating materials, components, or structures without causing damage to them. This type of inspection is important in various industries, such as manufacturing, construction, aerospace, and automotive, as it allows for the detection of flaws, defects, or anomalies without the need for disassembly or destruction of the object being inspected. Non-destructive inspection techniques include visual inspection, radiography, ultrasonic testing, magnetic particle testing, and liquid penetrant testing. These methods help ensure the safety, reliability, and quality of products and structures, ultimately saving time and costs in the long run.
