What Is Ultrasonic Flaw Detector Used For?

Apr. 19, 2022

Ultrasonic Flaw Detectors are sensors that use ultrasound to detect defects. These devices are used in all industries, including transportation, railroads, aviation, infrastructure projects, manufacturing, turbines, and the oil and gas industry.


These flaw detectors are popular because they apply NDT or non-destructive techniques using ultrasound. Using these does not damage the material and object being tested and gives accurate results. Ultrasonic flaw detectors are part of a range of tools used by non-destructive testing (NDT) engineers, inspectors or technicians, metallurgists, and materials engineers to ensure the integrity of parts and materials.


This can save a lot of money and prevent any accidents or disasters from occurring. In this article, let's check what to look for in an ultrasonic flaw detector that will be useful for your business and other needs.

 Applications of Ultrasonic Flaw Detectors

Applications of Ultrasonic Flaw Detectors

1. Accurate Analysis and Reporting

Ultrasonic flaw detectors are used to obtain the various measurements that must be accurate. In addition to this, they should be able to provide quick results for timely decisions. The data should be measured quickly in order to generate the required reports. This can be achieved with embedded software that provides a wide range of inspection tools, scan configuration, and analysis capabilities.

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.

2. Rugged and easy to use

Flaw detection equipment is used in several industries, including outdoors, in different media (e.g., water, slurry), and with extreme temperature changes (including humidity and heat). Ultrasonic flaw detectors should be easy to train and operate, as technicians must work under challenging conditions to obtain accurate reports. On top of that, it would be a blessing if they were battery-powered and cordless.


HS PA20-Fx Ultrasonic Flaw Detector is a high-end phased array flaw detector, which is specially developed for the high-end detection requirements of the market. The Ultrasonic Flaw Detector has 64/128 detection channels, which can detect complex structures or materials such as ultra-thick carbon steel and honeycomb plate. Matching a double crystal matrix array probe can solve the problem of thick stainless steel detection. The HS PA20-Fx Ultrasonic Flaw Detector can be equipped with two groups of TOFD detection channels, which can scan the weld with a thickness of 100 mm at one time.

3. Mobile and portable

Ultrasonic detectors are used in a variety of fields. Oil and gas exploration, pipelines, infrastructure projects, and some other industries have sites and structures located remotely. Therefore, mobile flaw detectors that can be easily transported and operated to remote sites become a necessity.


Lightweight portable flaw detectors will be easy to carry and operate. In addition to this, ultrasonic flaw detectors with replaceable batteries will continue to work without the need for immediate recharging. Therefore, look for portable and mobile flaw detectors for these industry needs.

4. Provides high-resolution displays and images

High-resolution displays and images provide greater insight into defect detection. Inspectors can examine these clear images with enhanced capabilities to pinpoint the shape, size and location of defects, whether they are surface defects or sub-surface defects. Accurately deciphering defects leads to better judgment and decision-making, saving organizations money and avoiding easily avoidable disasters.   


HS Q6 Ultrasonic flaw detector is a lightweight, easy to carry, easy to operate, powerful hand-held flaw detector, which uses a true color highlight display, rocker type keys, SD card expansion storage, can be used in the oil and gas, aerospace, power generation and automobile industry in the most demanding testing environment for a long time.
