Nyob rau hauv lub zog cia chaw vuam tshuab, kom ntseeg tau qhov zoo thiab kev ncaj ncees ntawm cov pob qij txha yog qhov tseem ceeb tshaj plaws.Txhawm rau ua tiav qhov no, ntau txoj hauv kev tshuaj xyuas yog ua haujlwm los ntsuas cov pob qij txha rau qhov tsis xws luag, xws li fusion tsis txaus, tawg, lossis porosity.Tsab ntawv xov xwm no tshawb txog cov txheej txheem sib txawv rau kev tshuaj xyuas cov pob qij txha hauv lub zog cia qhov chaw vuam tshuab, muab cov neeg ua haujlwm nrog cov cuab yeej muaj txiaj ntsig rau kev tswj xyuas cov welds zoo.
- Kev Ntsuam Xyuas Kev Pom Zoo: Kev kuaj pom pom yog qhov yooj yim tshaj plaws thiab feem ntau siv txoj hauv kev los ntsuas cov pob qij txha.Cov neeg ua haujlwm pom qhov muag tshuaj xyuas qhov chaw vuam kom pom qhov tsis xws luag, xws li fusion tsis tiav, qhov tsis zoo ntawm qhov chaw, lossis kev tsis sib xws.Txoj kev no yuav tsum tau kawm qhov muag thiab teeb pom kev zoo kom raug txheeb xyuas cov teeb meem muaj peev xwm.
- Kev Xeem Tsis Muaj Kev Ua Phem (NDT) Cov Txheej Txheem: a.Kev Ntsuas Ultrasonic: Kev ntsuam xyuas ultrasonic siv lub suab nrov zaus los kuaj xyuas cov teeb meem sab hauv lossis qhov tsis xws hauv cov pob qij txha.Ultrasonic nthwv dej yog kis los ntawm kev sib koom ua ke, thiab cov nthwv dej uas cuam tshuam tau raug tshuaj xyuas los txheeb xyuas qhov txawv txav.Cov txheej txheem no tshwj xeeb tshaj yog rau kev kuaj xyuas cov kab nrib pleb lossis porosity.
b.Kev Ntsuas Hluav Taws Xob: Kev kuaj hluav taws xob muaj feem cuam tshuam nrog X-rays lossis gamma rays los ntawm kev sib koom ua ke thiab ntes cov duab ntawm cov yeeb yaj kiab lossis cov cuab yeej digital.Txoj kev no tuaj yeem nthuav tawm cov teeb meem sab hauv, xws li kev nkag mus tsis tiav lossis voids.Kev kuaj hluav taws xob yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig rau cov pob qij txha tuab lossis nyuaj.
c.Sib Nqus Particle Test: Sib nqus particle kuaj yog ua haujlwm los tshuaj xyuas cov ntaub ntawv ferromagnetic.Ib qho chaw sib nqus yog siv rau qhov sib koom ua ke, thiab cov khoom sib nqus tau siv rau saum npoo.Txhua qhov deg-breaking defects yuav ua rau cov magnetic particles rau pawg, qhia tias muaj ib tug flaw.
d.Dye Penetrant Testing: Dye penetrant testing yog siv los txheeb xyuas qhov tsis xws luag hauv cov pob qij txha.Ib qho xim dye yog siv rau saum npoo, thiab tom qab lub sijhawm teev tseg, cov xim ntau dhau raug tshem tawm.Tom qab ntawd tus tsim tawm yog siv, uas rub cov hlua khi tawm ntawm txhua qhov chaw tsis xws luag, ua rau lawv pom.
- Kev kuaj kev puas tsuaj: Hauv qee qhov xwm txheej, kev sim ua kom puas tsuaj yog tsim nyog los ntsuas qhov sib koom ua ke zoo.Qhov no suav nrog tshem tawm ib qho piv txwv ntawm qhov sib koom ua ke thiab ua rau nws mus rau ntau qhov kev sim, xws li kev sim tensile, khoov, lossis kuaj qhov tawv.Kev ntsuam xyuas kev puas tsuaj muab cov ncauj lus kom ntxaws txog kev sib koom ua ke ntawm cov khoom siv kho tshuab thiab tuaj yeem nthuav tawm qhov tsis xws luag.
Kev tshuaj xyuas cov pob qij txha hauv lub zog cia qhov chaw vuam tshuab yog qhov tseem ceeb rau kev ua kom cov vuam zoo thiab cov qauv kev ncaj ncees.Los ntawm kev siv cov kev soj ntsuam pom, cov txheej txheem tsis muaj kev puas tsuaj (xws li kev sim ultrasonic, kuaj hluav taws xob, kuaj cov khoom sib nqus, thiab kuaj cov xim dye penetrant), thiab, thaum tsim nyog, kuaj kev puas tsuaj, cov neeg ua haujlwm tuaj yeem soj ntsuam cov pob qij txha rau qhov tsis xws luag.Kev ua raws li kev soj ntsuam xyuas txhua yam pab tswj cov txheej txheem siab ntawm kev ua tau zoo thiab kev ntseeg siab hauv lub zog cia qhov chaw vuam daim ntawv thov.Kev tshuaj xyuas tsis tu ncua ua kom muaj kev txheeb xyuas sai thiab daws teeb meem ntawm txhua qhov teeb meem, ua rau kev txhim kho vuam zoo thiab kev ua haujlwm vuam tag nrho.
