Non-Destructive Testing (NDT) technology refers to a method that detects internal and surface defects of materials or finished products without compromising their structure or performance. It utilizes changes in heat, sound, light, electricity, magnetism, etc., caused by abnormalities or defects within the material’s structure. Using physical methods and advanced technical equipment, NDT can complete the detection of internal and surface defects.
Ultrasonic Testing (UT) is an important method in NDT, using high-frequency sound waves to probe for internal flaws in materials.
Working Principle of Ultrasonic Testing Equipment
UT equipment generates high-frequency sound waves that are transmitted into the material under test. When these sound waves encounter interfaces or defects within the material, phenomena such as reflection, refraction, or scattering occur. The receiver captures these returned signals and analyzes the material’s internal structure based on the signal’s time, amplitude, and shape. Different defects cause different echo characteristics, and by comparing with standard samples or theoretical models, one can determine the location, size, and type of defect.
