Nondestructive Testing Ultrasonic

Non-destructive ultrasonic testing utilizes high-frequency sound waves that propagate through the interior of materials. When these waves encounter defects or interfaces, they generate reflected echoes. By analyzing the characteristics of these echoes, the internal structure of the material can be evaluated. This method is used to detect coating thickness, material cracks, bubbles, and other flaws, making it suitable for quality control in metals, plastics, and composite materials.
Selection
Select the probe frequency based on the material type: 2-5 MHz for metals and 0.5-2 MHz for plastics. Consider the detection depth: high frequency is suitable for thin materials, while low frequency is suitable for thick materials. Match the couplant to ensure sound wave transmission: water-based couplants for regular surfaces and gel couplants for rough surfaces. Choose the instrument resolution according to the defect size: micro-cracks require a precision of 0.1 mm or higher. Environmental temperature affects the sound velocity, requiring calibration and compensation.

Ultrasonic Thickness Gauge Selection: Technical Considerations for Probe Configuration and Measurement Modes
This article primarily introduces the technical factors to consider when selecting an ultrasonic thickness gauge. In terms of probe configuration, the frequency affects both resolution and penetration depth, while crystal size determines adaptability to curvature and surface conditions.
