Detection defect size of airborne ultrasonic testing.

Ultrasound propagates through the air without the need for a coupling medium! It can detect materials that cannot be applied to water or oil, etc.

In ultrasonic testing, a contact medium (such as water, oil, or glycerin) was necessary to transmit ultrasonic waves to the test specimen; however, this testing method allows ultrasonic waves to propagate through the air without the need for a contact medium. Therefore, it can detect items that cannot be tested with water or oil. Our company offers the non-destructive testing image processing system, the air ultrasonic flaw detection device 'GSCAN type.AERO', which can conduct material inspections without a contact medium. 【Features】 ■ Air ultrasonic waves do not require a contact medium compared to the water immersion method, which is an advantage, but the condition of the defect size in air ultrasonic flaw detection should be confirmed. ■ A resin plate test specimen with paper artificial defects of φ9mm, φ7mm, φ5mm, and φ3mm was prepared, with the transmitting and receiving probes arranged opposite each other for flaw detection, and the detection status was confirmed. ■ For artificial defects up to φ3mm, the height of the transmitted pulse decreased, but it was still sufficiently possible to distinguish between the defect and the sound part. *For more details, please refer to the PDF document or feel free to contact us.
