Group scanning function, Supports dual phased array + TOFD scanning on the same screen

HS PA20-Ex ultrasonic flaw detector is a phased array flaw detector with 32/128 detection channels, which can solve more complex phased array detection problems, Real-time analysis of inspection data, which is more suitable for ultrasonic inspection requirements of complex structures or materials, Such as electric fusion welding PE pipe, hot melt welding PE pipe; steel skeleton PE pipe electric fusion welding; composite material inspection, etc. HS PA20-Ex ultrasonic flaw detector can be adapted to 2 groups of TOFD inspection channels and can scan welds covering 100mm thickness at one time.

What is a phased array imaging ultrasonic flaw detector?

The phased array imaging ultrasonic flaw detector can individually control the excitation time of each wafer in the phased array probe through software, thereby controlling the angle, focus position and focus size of the generated beam.

The geometric shapes of common probe arrays are as follows:

• Linear array

1-dimensional linear array

2-dimensional rectangular array

• Circular array

1-dimensional circular array

2D fan array

Advantages of ultrasonic phased array technology:

1. Real-time color imaging, including A/B/C/D and S-scan, is convenient for defect interpretation, and will not misjudge or miss defects;

2. The phased array technology can realize linear scanning, sector scanning and dynamic depth focusing, so that it has the characteristics of wide beam and multi-focus at the same time, so the detection speed can be faster and more accurate;

3. The phased array has higher detection flexibility, and can realize functions that other conventional detection technologies cannot achieve, such as the detection of complex workpieces;

4. It is easy to detect defects in various directions and different positions, with a high defect detection rate, wide detection range, and high quantitative and positioning accuracy;

5. The scanning device is simple, easy to operate and maintain; it is more convenient to use, no harm to the human body, and no pollution to the environment;

6. The test results are less affected by human factors, and the data is easy to store, manage and call, and connect to a computer to print and view. You can also directly connect the mouse to operate the instrument.

7. It can save a lot of costs. The multi-purpose of a probe + wedge at various angles can automatically generate graphic defect reports. If there is an internal network, you can directly send the quality inspection report to the data center for review.
