How can we judge the internal quality of 7075 aluminum sheet material after we buy it?The most commonly used is ultrasonic flaw detection, 7075 aluminum plate manufacturers will give you introduce 7075 aluminum plate ultrasonic flaw detection principle.

7075 is ultrasonic flaw detection using an internal physical nondestructive testing method directly in 7075 aluminum.

The defects are analyzed by ultrasonic directivity and sound wave during inspection.The size, quantity, shape, and defect characterization distribution of energy information reflected or transmitted by ultrasonic waves.

Ultrasonic flaw detection methods are many, such as the p-wave pulse reflection water immersion automated flaw detection method.The principle of the p-wave velocity pulse reflection flooding automation and flaw detection method is that the 7075 aluminum plate is placed on the wheel of a tank before flaw detection, and the data center can be mounted on the 7075 aluminum plate through a car with two probes, and the probe system is placed on the axial normal line of the 7075 aluminum plate.During the flaw detection, 7075 aluminum plate rotates at a constant speed, and the flaw detection vehicle moves at a constant speed, so that the ultrasonic wave can form a spiral scan of 7075 aluminum plate.

To be shown encountering a defect by the ultrasonic probe interface during transmission, when it is reflected and returns to its original path, as a high-frequency electrical pulse through the probe, expands.

Ultrasonic flaw detection and sensitivity, detection accuracy, no damage 7075, easy to operate, fast, no damage characteristics.

The above is the introduction of ultrasonic flaw detection principle of 7075 aluminum plate. If 7075 aluminum plate is needed, please consult us.
