Applications of Ultrasonic Flaw Detectors

Steel gates are widely used in water conservancy projects, mainly based on high quality steel plates, made by welding means, with rubber water stops on the surface, anti-corrosion methods for sandblasting and rust removal and hot spray zinc on the surface, widely used in hydropower stations, reservoirs, irrigation, rivers, environmental protection, sewage treatment, aquaculture and other water conservancy projects. The welding quality of steel gates is directly related to the safety of people's lives and property downstream of the gates, so the welding quality and welding detection methods of the gates are crucial.

Ultrasonic flaw detector as one of the non-destructive testing inspection methods, is not to destroy the processing surface on the basis of the application of ultrasonic instruments or equipment to detect, both to check the naked eye can not check the internal defects of the workpiece, but also can greatly improve the accuracy and reliability of detection.

Ultrasound is a mechanical wave, has a very high frequency, frequency ratio of more than 20 kilohertz, its energy is much greater than the energy of the same amplitude of the audible sound waves, has a strong penetrating ability. Ultrasonic waves used for flaw detection have a frequency of 0.4 - 25 megahertz, with the most used being 1 - 5 megahertz.

Because of the ability to quickly and easily, non-invasive, accurate detection and location of a variety of defects within the workpiece, and ultrasonic flaw detection has a large detection distance, small size of the detection device, light weight, easy to carry to the site flaw detection, fast detection, and flaw detection in the consumption of only coupling agent and wear probe, the total cost of detection is low, so it is increasingly widely used.

Multi-function Phased Array Ultrasonic Flaw Detector HS PA20-Aex

HS PA20-Aex（Bolt）is a kind of bolt special detecting instrument based on phased array guide wave detection technology. UT flaw detectors can realize the detection of multi specification in-service fastening bolts, 3D bolt structure simulation function was added based on the general function of the phased array, which could display the detection results in real time. Ultrasonic Flaw Detector is also supported multi-mode scanning in groups and special bolt detection software.
