Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
There has been no concrete pipe sheet silane surface impregnating depth non-destructive testing device and method fields in currently available technology
Research, the present invention provides a kind of based on ultrasonic wave impregnating with silane depth lossless detection method, and Ultrasonic Nondestructive technology is
Achieved the purpose that measure object thickness (depth), defect according to Ultrasonic Pulse-Echo principle, supersonic generator probe generates
Ultrasonic pulse enter testee, ultrasonic pulse is reflected back when reaching object backing material interface is connect by probe
It receives, according to the ultrasonic pulse time t used in the layer material communication process and velocity of wave v that measuring device records, can calculate
The thickness S of the layer material.Using ultrasonic reflections principle measurement object thickness when, ultrasonic wave propagated in measured material when
Between are as follows: timer timing since the supersonic generator of probe emits ultrasonic wave is reflected back toward to ultrasonic wave and is sensed by probe
Device stops timing when receiving, this period of timer record is required propagation time t.Currently, whether timer stops counting
When detection there are two types of method:
First method is to set a ultrasonic echo to ultrasonic receiver sensor to trigger the threshold value of its work, is surpassed
Timer starts timing when sonic generator emits ultrasonic wave to test specimen, receives sensing when the Mintrop wave of ultrasonic echo reaches
Device, and ultrasonic echo signal wave amplitude be more than setting threshold value when, timer stop timing, the threshold value be timer judgement
Ultrasonic echo Mintrop wave reaches the mark of receiving sensor, and in the process, the time measured by timer is that ultrasonic wave is trying
The total time propagated in part.Since ultrasonic wavelength with test specimen can couple shape because of supersonic generator circuit, energy converter, probe
Condition, temperature etc. change, and component size and the uniformity of distribution can also cause the variation of wavelength, wave inside test specimen
The point generation that long variation will lead to energy trigger sensor threshold value on ultrasonic echo Mintrop wave deviates forward or backward, i.e. the change of wavelength
Change and will lead to time advance or the delay of ultrasonic echo activation threshold value, will lead to ultrasonic wave that timer obtains at this time in quilt
The propagation time shortens or increases in test block, and especially when measuring relatively thin material, error can be bigger.
Second method is that timer starts timing when supersonic generator emits ultrasonic wave to test specimen, when ultrasound is returned
When the Mintrop wave peak value of wave is received sensor reception, timer stops timing, and in the process, the time measured by timer is
The total time propagated in test specimen for ultrasonic wave.This kind judges that the method for timer stopping timing being avoided that the mistake of first method
Difference, but high speed data acquisition system is needed in the method that wave crest arrival receiving sensor terminates timing to obtain higher sampling frequency
The microprocessor of rate and superior performance, this results in the volume of final instrument and cost to greatly increase.
The object of the present invention is to provide a kind of impregnating with silane depth non-destructive testing device and methods, have and are not destroying coagulation
The advantages of improving detection accuracy on the basis of the i.e. measurable impregnating with silane depth of native element structure.
