Lub hom phiaj ntawm NDT yog txhawm rau txheeb xyuas qhov tsis xws luag sab hauv lossis saum npoo, cov yam ntxwv ntawm cov qauv, lossis kev ua haujlwm tsis zoo ntawm cov khoom, cov khoom siv, lossis cov khoom siv siv lub cev lossis tshuaj lom neeg yam tsis muaj kev puas tsuaj lossis cuam tshuam rau kev ua haujlwm ntawm cov khoom raug kuaj. Nws cov txiaj ntsig tseem ceeb nyob hauv kev ua kom muaj kev nyab xeeb, txhim kho kev tswj kom zoo, thiab txuas ntxiv kev pab cuam lub neej.
Los ntawm txoj kev xav, NDT siv txoj hauv kev xws li suab nthwv dej (kev sim ultrasonic), hluav taws xob tsis zoo (kev sim tam sim no), thiab hluav taws xob (X- kuaj kab hluav taws xob) txhawm rau ntes cov teeb liab txawv txav hauv cov ntaub ntawv. Piv txwv li, ultrasonic tsis tuaj yeem ntes porosity hauv cov hlau welds nrog lub siab ntawm 0.1 hli; X-rays tuaj yeem txheeb xyuas qhov shrinkage kab noj hniav hauv castings nrog kev daws teeb meem txog li 2 μm.
Daim ntawv thov npog tag nrho cov kev lag luam saw:
Manufacturing Stage: Crack detection in automotive engine castings (detection rate >99.5%)
Kev Saib Xyuas Kev Pabcuam: Corrosion phab ntsa thickness ntsuas hauv cov kav dej (qhov tseeb ± 0.05 hli)
Kev Ntsuam Xyuas Kev Ntsuas: Kev qaug zog kev puas tsuaj ntawm lub dav hlau tsaws iav (raws li ASTM E1444 tus qauv) Kev lag luam cov qauv yog nruj; Piv txwv li, aerospace yuav tsum tau ntawv pov thawj NAS410, thiab lub zog hluav taws xob nuclear ua raws li ASME cov qauv. Cov kev hloov tshiab kawg suav nrog AI- txhawb nqa kev txheeb xyuas qhov tsis zoo (tus nqi tsis raug<3%) and the development of portable devices (such as handheld spectrometers weighing <2kg).
