Of all the various uses for ultrasonics, flaw detection is the oldest and the most common. Prior to 1950, the laws of physics that govern the propagation of sound waves through solid materials have been used to detect hidden cracks, voids, porosity, and other internal discontinuities in metals, composites, plastics, and ceramics. High frequency sound waves reflect from flaws in predictable ways, producing distinctive echo patterns that can be displayed and recorded by portable instruments. Ultrasonic testing is completely nondestructive and safe, and it is a well-established test method in many basic manufacturing, process, and service industries, especially in applications involving welds and structural metals.

Ultrasonic flaw detection is basically a comparative technique. Using appropriate reference standards along with a knowledge of sound wave propagation and generally accepted test procedures, a trained operator identifies specific echo patterns corresponding to the echo response from good parts and from representative flaws. The echo pattern from a test piece may then be compared to the patterns from these calibration standards to determine its condition.

The HFD-1 is a digital ultrasonic flaw(inclusion) detector with 800 x 480 WVGAdisplay for superior visibility in all lightingconditions, including direct sunlight.Using the advanced tunable squarewaveexcitation technology, the HFD-1 providesexcellent material penetration and a highsignal to noise ratio when detecting specialcomposite materials, highly attenuated orthick work pieces.The zoom function for the in-gate waveformallows users to observe the waveform detailconveniently with an optimized height towidth rate to insure a higher resolution.The HFD-1 has different color change ofthe waveform for visual and an optionalalarm function.The auto calibration includes fastcalibrating material velocity, probestime delay and angle of signal.The USB port allows access forupdating the software, downloadingand printing of the data.
