Cov txheej txheem ntawm kev sim tsis muaj kev puas tsuaj

Kev kuaj tsis yog kev puas tsuaj yog kev siv cov khoom siv acoustic, kho qhov muag, sib nqus thiab cov khoom siv hluav taws xob, thaum tsis muaj kev puas tsuaj lossis tsis cuam tshuam rau kev siv cov khoom raws li qhov ua tau zoo ntawm cov khoom raug tshuaj xyuas, kev kuaj xyuas qhov muaj qhov tsis xws luag. los yog inhomogeneities nyob rau hauv cov khoom raug soj ntsuam, muab qhov luaj li cas, qhov chaw, xwm thiab tus naj npawb ntawm cov tsis xws luag thiab lwm yam ntaub ntawv, thiab yog li txiav txim lub xeev ntawm technology nyob rau hauv uas cov khoom raug soj ntsuam. (piv txwv li, tsim nyog lossis tsis tsim nyog, lub neej seem, thiab lwm yam) Lub npe dav dav ntawm txhua txoj kev txhais tau tias.
Feem ntau siv cov kev sim uas tsis yog kev puas tsuaj: Ultrasonic Test (UT), Sib Nqus Particle Test (MT), Liquid Penetration Testing (PT) thiab X-ray Test (RT).
Kev kuaj ultrasonic
UT (Ultrasonic Testing) yog ib qho ntawm cov kev sim tsis muaj kev puas tsuaj hauv kev lag luam. Ultrasonic nthwv dej rau hauv cov khoom tau ntsib qhov tsis xws luag, ib feem ntawm lub suab nthwv dej yuav raug cuam tshuam, lub transmitter thiab receiver tuaj yeem txheeb xyuas qhov cuam tshuam yoj, nws tuaj yeem ntsuas qhov ntsuas qhov tsis xws luag, thiab tuaj yeem qhia qhov chaw thiab qhov loj ntawm qhov tsis xws luag, txiav txim qhov thickness ntawm cov khoom thiab lwm yam.
Ultrasonic soj ntsuam zoo:
1, lub peev xwm nkag mus yog loj, piv txwv li, nyob rau hauv cov hlau nyob rau hauv qhov zoo nrhiav kom pom qhov tob txog li 1 meter los yog ntau tshaj;.
2, rau lub dav hlau hom tsis xws luag xws li cov kab nrib pleb, interlayers, thiab lwm yam., qhov kev tshawb pom rhiab heev yog siab dua, thiab tuaj yeem txiav txim siab qhov tob thiab txheeb ze ntawm qhov tsis xws luag;
3, cov khoom siv hnyav, kev ua haujlwm nyab xeeb, yooj yim kom paub txog kev tshuaj xyuas.
Qhov tsis zoo:
Tsis yooj yim rau kev kuaj xyuas cov duab ntawm lub workpiece, yuav tsum muaj qee qhov kev sib tw ntawm qhov chaw kuaj xyuas, thiab qhov xav tau rau tus neeg sawv cev sib txuas los ua kom tiav qhov sib txawv ntawm qhov kev sojntsuam thiab qhov chaw kuaj xyuas kom paub meej txaus acoustic coupling.
Magnetic particle soj ntsuam
Ua ntej tshaj plaws, cia peb nkag siab lub hauv paus ntsiab lus ntawm kev tshuaj xyuas cov khoom sib nqus. Tom qab cov hlau nplaum ntawm ferromagnetic cov ntaub ntawv thiab cov khoom ua haujlwm, vim muaj qhov tsis sib xws, cov kab sib nqus ntawm lub zog ntawm qhov chaw ua haujlwm thiab nyob ze ntawm qhov chaw ntawm lub zos distortion, thiab tsim cov xau tawm, adsorption ntawm magnetic hmoov siv rau saum npoo. ntawm lub workpiece, tsim ib tug visually pom cov kab nrib pleb nyob rau hauv lub teeb tsim nyog, yog li qhia qhov chaw, cov duab thiab qhov loj ntawm qhov discontinuity.

Kev siv tau thiab kev txwv ntawm kev tshuaj xyuas cov khoom sib nqus yog:
1, magnetic particle flaw detection yog tsim nyog rau kev kuaj xyuas qhov tsis sib xws ntawm qhov chaw thiab nyob ze ntawm cov ntaub ntawv ferromagnetic uas yog qhov me me thiab muaj qhov tsis tshua muaj nqaim uas nyuaj rau pom kev pom.
2, magnetic particle soj ntsuam tuaj yeem ua tau ntau yam ntawm qhov kev tshawb nrhiav, tab sis kuj muaj ntau hom kev kuaj xyuas.
3, Cov kab nrib pleb, suav nrog, kab plaub hau, pob dawb, folding, txias cais thiab xoob thiab lwm yam tsis xws luag tuaj yeem pom.
4, kev soj ntsuam cov khoom sib nqus tsis tuaj yeem kuaj xyuas cov khoom siv hlau tsis zoo austenitic thiab welds welded nrog austenitic stainless hlau vuam electrodes, thiab tsis tuaj yeem ntes tooj liab, txhuas, magnesium, titanium thiab lwm yam khoom tsis sib nqus. Rau qhov chaw ntawm qhov chaw ntiav, faus qhov tob thiab nrog lub workpiece nto lub kaum sab xis tsawg dua 20 degree delamination thiab folding yog qhov nyuaj nrhiav.
Ua kua nkag mus nrhiav kom tau
Lub hauv paus ntsiab lus ntawm kev ua kua nkag mus rau hauv qhov chaw, qhov chaw ntawm qhov chaw yog coated nrog fluorescent dyes los yog xim dyes, nyob rau hauv ib lub sij hawm ntawm qhov kev txiav txim ntawm capillary, cov kua nkag tau nkag mus rau hauv qhov chaw qhib qhov tsis xws luag; Tom qab tshem tawm cov kua dej ntau dhau ntawm qhov chaw, thiab tom qab ntawd coated nrog tus tsim tawm ntawm qhov chaw ntawm qhov chaw.
Ib zaug ntxiv, nyob rau hauv qhov kev txiav txim ntawm capillary, tus tsim tawm yuav nyiam cov permeate khaws cia hauv qhov tsis xws luag, cov permeate seeps rov qab rau hauv tus tsim tawm, thiab nyob rau hauv ib qho teeb pom kev zoo (ultraviolet lub teeb los yog lub teeb dawb), kab ntawm permeate ntawm qhov tsis xws luag. yog tso tawm kom pom, (daj-ntsuab fluorescence lossis ci liab), thiaj li txhawm rau txheeb xyuas qhov tsis xws luag morphology thiab kev faib tawm.
Qhov zoo ntawm kev tshawb nrhiav penetrant yog:
1, tuaj yeem ntes ntau yam khoom siv;
2, nrog siab rhiab heev;
3, cov zaub yog intuitive, yooj yim rau kev khiav lag luam, tsis tshua muaj nqi kuaj.
Thiab qhov tsis zoo ntawm kev ntsuas kev nkag mus yog:
1, tsis haum rau kev tshuaj xyuas lub workpiece ua los ntawm cov khoom ntxeem tau xoob thiab ntxhib nto workpiece;
2, kev ntsuam xyuas qhov nkag tuaj yeem tsuas yog kuaj pom qhov sib faib ntawm qhov tsis xws luag, nws yog qhov nyuaj los txiav txim siab qhov tseeb qhov tob ntawm qhov tsis xws luag, thiab yog li nws yog qhov nyuaj rau kev ntsuas qhov ntsuas ntawm qhov tsis xws luag. Cov txiaj ntsig tshawb pom kuj cuam tshuam los ntawm tus neeg teb xov tooj.
X-ray soj ntsuam
Qhov kawg, kev kuaj pom hluav taws xob, vim tias X-rays los ntawm cov khoom irradiated yuav poob, cov thicknesses sib txawv ntawm cov khoom sib txawv ntawm lawv qhov nqus tau sib txawv, thiab qhov tsis zoo yog muab tso rau ntawm lwm sab ntawm cov khoom irradiated, vim qhov kev siv ntawm cov khoom sib txawv. ray yog txawv thiab tsim cov duab sib xws, cov neeg soj ntsuam cov yeeb yaj kiab tuaj yeem ua raws li cov duab los txiav txim seb qhov khoom puas yog thiab qhov xwm txheej ntawm qhov tsis xws luag hauv khoom.

Kev siv thiab kev txwv ntawm kev tshuaj xyuas radiographic:
1. Nws yog rhiab heev rau kev soj ntsuam volumetric defects, thiab nws yog yooj yim dua rau characterize qhov tsis xws luag.
2, Radiographic negatives yog ib qho yooj yim khaws cia thiab muaj traceability.
3, Pom cov duab thiab hom tsis xws luag.
4, qhov tsis zoo tsis tuaj yeem nrhiav qhov tob tob ntawm qhov tsis xws luag, thaum kuaj pom cov tuab tuab, qhov tsis zoo yuav tsum raug xa mus rau kev ntxuav, thiab qee qhov kev puas tsuaj rau tib neeg lub cev, tus nqi siab dua.
Nyob rau hauv luv luv, ultrasonic, X-ray flaw detection yog haum rau kev soj ntsuam sab hauv; qhov twg ultrasonic rau ntau tshaj 5 hli, thiab cov duab ntawm qhov tsis tu ncua, X-ray tsis tuaj yeem nrhiav qhov faus qhov tob ntawm qhov tsis xws luag, hluav taws xob. Sib nqus particle thiab nkag mus rau qhov tsis txaus ntseeg yog tsim los xyuas qhov tsis xws luag ntawm qhov chaw; Ntawm lawv, sib nqus partle qhov pom kom pom tau yog txwv rau kev kuaj pom cov khoom sib nqus, thiab kev nkag mus rau qhov tsis pom zoo ntawm qhov chaw.
