Chidziwitso chowunikira zowonongeka

1. NDT imatanthawuza njira yoyesera ya zida kapena zogwirira ntchito zomwe siziwononga kapena kukhudza momwe amagwirira ntchito kapena kugwiritsa ntchito mtsogolo.

2. NDT angapeze zolakwika mkati ndi pamwamba pa zipangizo kapena workpieces, kuyeza makhalidwe geometric ndi miyeso ya workpieces, ndi kudziwa zikuchokera mkati, dongosolo, katundu thupi ndi boma la zipangizo kapena workpieces.

3. NDT ingagwiritsidwe ntchito pakupanga zinthu, kusankha zinthu, kukonza ndi kupanga, kuyang'anira zinthu zomalizidwa, kuyang'anira ntchito (kukonza), ndi zina zotero, ndipo zimatha kugwira ntchito yabwino pakati pa kuwongolera khalidwe ndi kuchepetsa mtengo.NDT imathandizanso kuwonetsetsa kuti ntchito yotetezeka komanso / kapena kugwiritsa ntchito moyenera zinthu.

Mitundu ya njira za NDT

1. NDT imaphatikizapo njira zambiri zomwe zingagwiritsidwe ntchito bwino.Malinga ndi mfundo zakuthupi kapena zinthu zoyesera ndi zolinga, NDT ikhoza kugawidwa m'njira zotsatirazi:

a) Njira ya radiation:

——Kuyesa kwa X-ray ndi gamma ray;

——Kuyesa kwa radiographic;

——Kuyesa kwa makompyuta;

——Kuyesa kwa neutron radiographic.

b) Njira yamayimbidwe:

——Kuyesa kwa Ultrasonic;

——Kuyezetsa mpweya womvera;

——Kuyezetsa kwamagetsi kwamagetsi.

c) Njira yamagetsi:

——Eddy panopa kuyezetsa;

——Kuyezetsa kutayikira kwa Flux.

d) Njira ya pamwamba:

——Kuyesa kwa tinthu tamagetsi;

——Kuyesa kwamadzi olowera;

——Kuyesa kowonekera.

e) Njira yodutsira:

——Kuyezetsa kutayikira.

f) Njira ya infrared:

——Kuyezetsa matenthedwe a infrared.

Zindikirani: Njira zatsopano za NDT zitha kupangidwa ndikugwiritsidwa ntchito nthawi iliyonse, kotero njira zina za NDT sizimachotsedwa.

2. Njira zodziwika bwino za NDT zimatengera njira zomwe zimagwiritsidwa ntchito kwambiri komanso zokhwima za NDT pakadali pano.Ndi mayeso a radiographic (RT), ultrasonic test (UT), eddy current test (ET), magnetic particle test (MT) ndi penetrant test (PT).
