Dab tsi yogkev kuaj tsis muaj kev puas tsuaj?

Kev ntsuam xyuas tsis muaj kev puas tsuaj, hu ua NDT, yog ib qho kev tshuaj ntsuam xyuas niaj hnub no uas kuaj pom cov duab, txoj hauj lwm, qhov loj thiab kev loj hlob ntawm cov teeb meem sab hauv lossis sab nraud yam tsis muaj kev puas tsuaj rau cov khoom yuav raug tshuaj xyuas. Nws tau siv dav hauv kev tsim cov yeeb nkab steel hauv xyoo tas los no. Cov kev sim uas tsis yog kev puas tsuaj siv rau hauv kev tsim khoomseamless kav & rajFeem ntau suav nrog kev sib nqus particle kuaj, kuaj ultrasonic, eddy tam sim no kuaj, kuaj radiographic, kuaj penetrant, thiab lwm yam.

1. Sib nqus Particle Test
Siv cov hmoov sib nqus rau saum npoo ntawm cov yeeb nkab seamless mus kuaj, siv cov hlau nplaum los yog tam sim no kom nws nkag mus rau qhov tsis xws luag, tsim cov khoom sib nqus sib nqus, thiab tom qab ntawd soj ntsuam qhov tso tawm ntawm cov hmoov sib nqus kom pom qhov tsis xws luag.

2. Ultrasonic kuaj
Siv cov yam ntxwv ntawm ultrasonic propagation nyob rau hauv cov ntaub ntawv, los ntawm kev xa thiab tau txais ultrasonic signals, nws pom qhov tsis xws luag los yog hloov nyob rau hauv seamless kav.

3. Eddy kev sim tam sim no
Kev sib hloov electromagnetic teb ua rau ntawm qhov chaw ntawm cov yeeb nkab uas tau soj ntsuam seamless los tsim cov eddy tam sim no thiab xyuas cov khoom tsis xws luag.

4. Kev tshuaj xyuas hluav taws xob
Lub raj tsis muaj seamless kuaj yog irradiated nrog X-rays lossis γ-rays, thiab qhov tsis xws luag hauv cov khoom raug kuaj pom los ntawm kev kuaj pom kev sib kis thiab tawg ntawm cov kab hluav taws xob.

5. Kev xeem nkag
Cov kua dye yog siv rau ntawm qhov chaw ntawm qhov ntsuas seamless raj, thiab nws tseem nyob rau ntawm lub cev nto rau lub sij hawm preset. Cov zas xim tuaj yeem yog cov kua xim uas tuaj yeem pom nyob rau hauv lub teeb ib txwm muaj, lossis cov kua fluorescent daj / ntsuab uas xav tau lub teeb tshwj xeeb kom tshwm. Cov kua dye "wicks" rau hauv qhov qhib kab nrib pleb nyob rau saum npoo ntawm cov khoom. Capillary kev txiav txim txuas ntxiv mus thoob plaws hauv cov xim dye mus txog thaum cov xim ntau dhau raug ntxuav tag. Lub sijhawm no, ib tus neeg saib xyuas cov duab tau siv rau saum npoo ntawm cov khoom siv los kuaj xyuas, nkag mus rau hauv qhov tawg thiab ua rau nws xim, thiab tom qab ntawd tshwm.

Cov saum toj no yog cov hauv paus ntsiab lus ntawm tsib qhov kev sim tsis muaj kev puas tsuaj, thiab cov txheej txheem kev ua haujlwm tshwj xeeb yuav sib txawv raws li cov qauv sib txawv thiab cov khoom siv.
