The mobile limiting device of head.
Background technique
Ultrasonic phased array obtains that principle is similar with conventional ultrasound detection, is all based on the principle of pulse reflection method.Ultrasound
The relatively conventional ultrasonic wave advantage of phased array mainly includes the following aspects:
(1) phased array is swept using S, i.e., can possess the ultrasonic wave of many angles simultaneously, be equivalent to possess multiple angles
Probe work at the same time, so phased array be not necessarily to Zigzag scan, as long as moving probe along weld seam, detection efficiency is higher.
Suitable for automated production, and batch production.
(2) phased array can possess focusing function, and conventional ultrasound is typically no (other than focusing probe), so phase
The sensitivity and resolution ratio for controlling battle array detection all detect than conventional Ultrasound high.
(3) phased array detection can possess that B is swept, D is swept, S is swept and C-scan simultaneously, can establish a three-dimensional by modeling
Solid figure, defect show very intuitive, even the people for being ignorant of NDT can see clear, and conventional ultrasound can only pass through waveform
To differentiate defect.
(4) ultrasonic phase array can detecte complex part, for example can detecte the blade root of turbo blade, conventional ultrasound inspection
It surveys because probe acoustic beam angle is single, there is very big blind area, cause missing inspection.And phased array can be quick, it is intuitive to detect.
(5) ultrasonic phase array can record detection process, realize the retrospective of detection, and conventional Ultrasound can only lean on artificially
Judge that waveform comes to a conclusion to testing result.
Just because of the above-mentioned advantage of ultrasonic phased array technology, it is applied more and more extensive in non-destructive testing engineering.
It is not necessarily to Zigzag scan when ultrasonic phase array detects, only need to move towards scanning one along weld seam away from detected weld certain distance
The secondary whole detection that can be completed to weld seam.
It in phased array detection, needs to be accurately positioned the defect of discovery, positioning is inaccurate to later period defect processing band
Carry out very big trouble.The front end of probe with weld seam distance a is passed through previously according to parameters such as thickness, the weld widths of plate
