Specific embodiment
The present invention is described further with reference to the accompanying drawings and examples.
As shown in Figures 1 to 4, a kind of heavy water reactor spentnuclear fuel basket shroud RB-C1# welds comparison test block, generally arc panel
Shape, inner sidewall and lateral wall are arcwall face, and upper surface and lower end surface are horizontal plane, and left side and right side are vertical plane.?
The left part of test block upper surface is opened up along the vertical direction there are two detection hole, for simulating defect present in weld seam.
Test block entire length is 150mm, is highly 40mm, outer arc radius 57mm, inner arc radius 45mm.Two
Detection hole is through-hole, is sequentially arranged test block upper surface is forward and backward, diameter 1.5mm, and the distance between two detection holes is 4mm, after
Portion's detection hole and external arc end face distance are 6mm, and two detection holes are 60mm at a distance from test block left side.
Right part etching and processing in test block upper surface identifies, and word depth 0.2mm etches position pigment coloration.
In the present embodiment, test block integrally uses 022Cr19Ni10 type stainless steel material to be made.
Application method of the invention is as follows:
1. the probe using ultrasonic nondestructive testing device is scanned test block, records institute's detection waveform and store to super
Sound wave non-destructive testing device；
2. the probe of ultrasonic nondestructive testing device is placed in outside fuel-basket shroud at cross joint, outside is moved up and down, and
It is compared with the test block detection waveform of storage, if the detection waveform amplitude at cross joint is greater than the vibration of test block detection waveform
Width then illustrates that there are problems for weldquality herein, need to further do PT penetration inspection, detect venthole position and accordingly mended
Weldering.
3. carrying out Ultrasonic Nondestructive again after the completion of repair welding, examined using the probe of ultrasonic nondestructive testing device
It looks into, and is compared with the test block detection waveform of storage, be less than test block detection wave as detected the detection waveform amplitude at cross joint again
The amplitude of shape then illustrates this weld seam no problem, meets welding requirements.The detection waveform amplitude such as detected at cross joint again is still big
In the amplitude of test block detection waveform, then illustrate that this weld seam problem still remains, needs to carry out repair welding until meeting the requirements.
4. the probe of ultrasonic nondestructive testing device is placed on the outside of fuel-basket shroud exterior circumference commissure, probe is carried out
Circular motion is simultaneously compared with the test block detection waveform of storage, if the detection waveform amplitude at circumferential weld is examined greater than test block
The amplitude for surveying waveform then illustrates that there are problems for weldquality herein, need to further do PT penetration inspection, detect venthole position
And carry out corresponding repair welding.
5. carrying out Ultrasonic Nondestructive again after the completion of repair welding, examined using the probe of ultrasonic nondestructive testing device
It looks into, and is compared with the test block detection waveform of storage, detected as detected the detection waveform amplitude at circumferential weld again less than test block
The amplitude of waveform then illustrates this weld seam no problem, meets welding requirements.As detected the detection waveform amplitude at circumferential weld again
It is still greater than the amplitude of test block detection waveform, then illustrates that this weld seam problem still remains, needs to carry out repair welding until meeting the requirements.
The above is only the preferred embodiments of the invention, is illustrated herein: method based on the principle of the invention improve and
Structural adjustment all will be regarded as protection scope of the present invention.
