Portable NDT Instrument MEES-803

MEES-803 is an all-in-one detector including ECA, video inspection, satellite positioning, high sensitivity/broadband high-resolution UT, swept frequency, RF, MIA. It is designed for flaw inspection of metal material, and for sorting of alloy, heat treatment condition and thickness. The UT inspection, combined with strong emission high penetration and high sensitivity narrow band, is especially suitable for flaw detection of large heavy workpieces such as large forgings, castings and composites. The narrow pulse probe worked together with weak emission high resolution and broadband enables to find tiny flaws with very high sensitivity. Results from different inspection methods make engineers easy to analyze and easy to verify. This helps to obtain a more objective and true evaluation. The application fields including aviation, aerospace, electric power, nuclear industry, metallurgy, shipbuilding, petrochemical industry, automobile and so on. It is especially suitable for flaw detection of composite material and adhesive structural parts.

02  UT, SWEPT FREQUENCY, RF, PULSE, MIA

·UT A scan: UT is widely used for internal flaw inspection of metal, nonmetal and composites. Ultrasonic pulse echo and pulse through methods are commonly used to detect poor bonding, debonding, holes and bonding quality for thick composite materials such as multi-layer metal bonded composite plate.

·Swept frequency: the bonding quality is determined by amplitude change of return signals detected, processed and displayed by transmitting transducer, which is excited by electronic swept frequency (no couplant required, frequency range 20K~80KHz, can be extended to 5MHz).

·RF: debonding is determined by amplitude and phase change, which is measured by steady-state excitation from continuous wave (no couplant required).

·Pulse: the transmitting transducer is excited by short pulse, and the best frequency is selected to make the workpiece generate the biggest bending vibration. When the probe scans over the poor bonding area, the signal amplitude will be bigger than that on the good area (no couplant required).

·MIA: the transmitting transducer vibrates the work piece being tested. The mechanical impedance reflecting the work piece vibration performance reacts on the receiving chip to constitute the load of the transducer. When there’s any defect or any bonding quality change, the vibration performance will change too. By measuring these changes, the discontinuity of the work piece under test can be found (no couplant required)
