Ultrasonic Flaw Detector

Introduction:

The ultrasonic flaw detector is a portable, all-digital ultrasonic flaw detector that enables rapid detection, positioning, evaluation and diagnostics of defects, cracks, inclusions, stomata, etc. functions. It can be used in the laboratory, and can also be used for engineering site. The instrument can be widely used in the field of manufacturing, iron and steel metallurgy, metal processing industry, chemical industry and other defects in the detection and quality control, but also widely used in aerospace, railway transportation, boiler and pressure vessels in the field of safety checks and life assessment.

Detection function:

Flaw detection standards: built-in industry commonly used testing standards, direct call, convenient and fast

Weld diagram: can be set to weld the shape parameters, the visual inspection of the weld map and defects in the weld position

Automatic calibration: probe zero and probe angle (K value) automatic calibration function; automatic speed measurement function

Peak memory: real-time retrieval of defects in the highest wave, record the maximum defect

Defect Quantification: Defect Equivalent dB value is displayed in real time

Defect qualitative: through the echo envelope waveform, easy to determine the manual experience

Surface correction: for the surface of the workpiece testing, real-time display defects in the circumferential position

DAC / AVG: curve is automatically generated, sampling points are not restricted, and can be compensated and amended. Curve with the increasing benefits, automatically floating, with the automatic expansion of the sound, with the delay automatically move. Can display any aperture The AVG curve.

AWS D1.1: American Society for Welding Standards provides a dynamic reflector "defect rating" for all types of AWS weld inspection applications. Can avoid manual calculation, improve detection efficiency.

Crack height measurement: the use of endpoint diffraction wave automatic measurement, calculate the crack height.

Door expansion: enlarge echo details, easy to echo analysis

Continuous recording: real-time recording of waveforms, storage, playback

Waveform Freeze: Freeze the waveform displayed on the screen for easy defect analysis

Echo code: 1 to 6 times in different colors display echo display area, easy to determine the defect location

B-type scanning: real-time scanning, cross-section display, the use of color coding, with different shades of color to mark the different depth of echo information.
