Non-Destructive Testing (NDT) yog cov txheej txheem siv los txheeb xyuas qhov tsis xws luag hauv cov khoom lossis cov khoom yam tsis muaj kev cuam tshuam rau lawv txoj kev ncaj ncees. Rau cov khoom lag luam xws li forgings, kev sim tsis muaj kev puas tsuaj ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo thiab kev ntseeg siab.
Cov hauv qab no yog ob peb txoj kev kuaj tsis muaj kev puas tsuaj uas siv tau rau forgings:
Kev Ntsuas Ultrasonic (UT): Los ntawm kev xa cov suab nrov nthwv dej ntau zaus rau forgings, echoes raug kuaj pom los txiav txim qhov chaw, qhov loj me, thiab morphology ntawm qhov tsis xws luag. Txoj kev no tuaj yeem ntes cov kab nrib pleb, qhov pores, suav nrog, thiab lwm yam teeb meem hauv forgings.
Sib Nqus Particle Testing (MT): Tom qab siv lub magnetic teb rau saum npoo ntawm forging, magnetic particles dispersed rau nws. Yog tias muaj cov kab nrib pleb lossis lwm yam tsis xws luag tam sim no, cov khoom sib nqus yuav sib sau ua ke ntawm cov teeb meem no, yog li pom lawv.
Liquid Penetrant Testing (PT): Txheej txheej ntawm lub forging nrog cov kua permeable los sau nws nrog qhov tsis xws luag thiab tshem tawm tom qab ib ntus. Tom qab ntawd, tus neeg sawv cev txhim kho yog siv los tso cai rau cov kua permeable nkag mus thiab tsim cov cim pom ntawm qhov tawg lossis qhov chaw tsis raug.
X-ray Testing (RT): Siv X-rays lossis gamma rays los nkag rau hauv forgings thiab tsim cov duab ntawm cov yeeb yaj kiab photosensitive. Txoj kev no tuaj yeem kuaj xyuas qhov tsis xws li kev hloov pauv ceev thiab tawg hauv forgings.
Cov saum toj no tsuas yog teev ntau yam kev sim tsis muaj kev puas tsuaj, thiab txoj kev tsim nyog yuav tsum raug xaiv raws li hom forging, specification yuav tsum tau, thiab cov xwm txheej tshwj xeeb. Tsis tas li ntawd, kev ntsuam xyuas tsis muaj kev puas tsuaj feem ntau yuav tsum muaj kev cob qhia kev tshaj lij thiab cov neeg ua haujlwm tau ntawv pov thawj los xyuas kom meej qhov kev ua tiav thiab kev txhais cov txiaj ntsig.
