Kev kuaj tsis yog kev puas tsuaj yog siv cov yam ntxwv ntawm lub suab, lub teeb, hlau nplaum thiab hluav taws xob los xyuas seb puas muaj qhov tsis xws luag lossis tsis sib xws hauv cov khoom yuav raug tshuaj xyuas yam tsis muaj kev puas tsuaj lossis cuam tshuam rau kev ua haujlwm ntawm cov khoom yuav tsum tau kuaj xyuas, thiab muab qhov loj me. , txoj hauj lwm, thiab qhov chaw ntawm qhov tsis xws luag. Lub ntsiab lus dav dav rau txhua txoj kev txhais tau tias los txiav txim siab txog lub xeev ntawm cov khoom kuaj xyuas (xws li seb nws puas tsim nyog lossis tsis tsim nyog, lub neej tseem tshuav, thiab lwm yam)
Feem ntau siv cov kev sim uas tsis yog kev puas tsuaj: kev kuaj ultrasonic (UT), kuaj cov hlau nplaum sib nqus (MT), ntsuas dej nkag (PT) thiab kuaj X-ray (RT).
Kev kuaj ultrasonic
UT (Ultrasonic Testing) yog ib qho ntawm cov kev lag luam tsis muaj kev puas tsuaj. Thaum lub ultrasonic nthwv dej nkag mus rau hauv ib qho khoom thiab ntsib qhov tsis xws luag, ib feem ntawm lub suab nthwv dej yuav raug cuam tshuam, thiab lub transmitter thiab receiver tuaj yeem txheeb xyuas qhov cuam tshuam ntawm nthwv dej, thiab qhov tsis xws luag tuaj yeem kuaj pom tau zoo heev. Thiab nws tuaj yeem tso saib txoj haujlwm thiab qhov loj ntawm qhov tsis xws luag, ntsuas cov khoom tuab, thiab lwm yam.
Qhov zoo ntawm kev kuaj ultrasonic:
1. Muaj peev xwm nkag mus tau loj, piv txwv li, qhov kev tshawb pom qhov tob hauv cov hlau tuaj yeem ncav cuag ntau tshaj 1 meter;
2. Rau qhov tsis xws luag xws li cov kab nrib pleb, interlayers, thiab lwm yam, qhov kev tshawb pom rhiab heev, thiab qhov tob thiab txheeb ze ntawm qhov tsis xws luag tuaj yeem ntsuas tau;
3. Cov cuab yeej siv tau yooj yim, kev ua haujlwm muaj kev nyab xeeb, thiab nws yooj yim kom paub txog kev tshuaj xyuas tsis siv neeg.
tsis txaus:
Nws tsis yooj yim rau kev tshuaj xyuas cov khoom ua haujlwm nrog cov duab nyuaj, thiab qhov chaw yuav tsum tau kuaj xyuas yuav tsum muaj qee qhov kev sib tw, thiab qhov sib txawv ntawm qhov kev sojntsuam thiab qhov chaw yuav tsum tau kuaj xyuas yuav tsum tau ntim nrog couplant kom paub meej txaus acoustic coupling.
Sib Nqus Particle Test
Ua ntej ntawm tag nrho cov, cia peb nkag siab lub hauv paus ntsiab lus ntawm magnetic particle kuaj. Tom qab cov khoom siv ferromagnetic thiab cov khoom ua haujlwm tau magnetized, vim qhov muaj qhov tsis sib xws, cov kab hlau nplaum ntawm qhov chaw thiab nyob ze ntawm qhov chaw ua haujlwm yog distorted hauv zos, uas ua rau muaj qhov sib nqus sib nqus, uas absorbs cov hmoov sib nqus ntawm cov khoom siv. nto ntawm lub workpiece, thiab tsim ib tug pom magnetic teb nyob rau hauv haum lub teeb. cov kab, yog li qhia qhov chaw, cov duab thiab qhov loj ntawm qhov tsis sib xws.
Kev siv tau thiab cov kev txwv ntawm kev ntsuas magnetic particle yog:
1. Kev tshuaj xyuas cov khoom sib nqus yog tsim nyog rau kev kuaj xyuas qhov tsis sib xws uas me me ntawm qhov chaw thiab nyob ze ntawm cov khoom siv ferromagnetic, thiab qhov sib txawv yog qhov nqaim heev thiab tsis yooj yim rau kev pom qhov muag.
2. Kev tshuaj xyuas cov khoom sib nqus tuaj yeem kuaj xyuas qhov chaw hauv ntau qhov xwm txheej, thiab tseem tuaj yeem ntes ntau yam ntawm qhov chaw.
3. Cov kab mob xws li cov kab nrib pleb, suav nrog, cov kab plaub hau, cov pob dawb, cov quav, qhov txias kaw thiab xoob tuaj yeem pom.
4. Kev ntsuam xyuas cov khoom sib nqus tsis tuaj yeem ntes cov ntaub ntawv austenitic stainless hlau thiab welds welded nrog austenitic stainless hlau electrodes, thiab nws tsis tuaj yeem ntes cov khoom tsis sib nqus xws li tooj liab, txhuas, magnesium thiab titanium. Nws yog ib qho nyuaj rau nrhiav delaminations thiab folds nrog ntiav khawb ntawm qhov chaw, faus qhov tob, thiab cov ces kaum tsawg dua 20 ° nrog lub workpiece nto.

kev ntsuam xyuas kua penetrant
Lub hauv paus ntsiab lus ntawm kev ntsuam xyuas cov kua penetrant yog tias tom qab qhov chaw ntawm qhov chaw yog coated nrog fluorescent dyes los yog xim dyes, tus penetrant tuaj yeem nkag mus rau hauv qhov chaw qhib qhov tsis xws luag hauv qab capillary ua rau lub sijhawm; Tom qab tshem tawm qhov dhau ntawm qhov nkag mus rau ntawm qhov chaw, tus tsim tawm A yog siv rau qhov chaw ntawm qhov chaw.
Ib yam li ntawd, nyob rau hauv qhov kev txiav txim ntawm capillary, tus neeg saib xyuas yuav nyiam cov dej nkag mus rau hauv qhov tsis xws luag, thiab cov dej nkag nkag mus rau hauv cov duab pom, thiab nyob rau hauv ib qho teeb pom kev zoo (ultraviolet light los yog dawb lub teeb), kab ntawm Cov kua dej nkag mus rau ntawm qhov tsis xws luag yog tso tawm, (daj-ntsuab fluorescence lossis ci liab), thiaj li txhawm rau txheeb xyuas cov morphology thiab kev faib tawm ntawm qhov tsis xws luag.
Qhov zoo ntawm kev ntsuas kev nkag mus yog:
1. Nws tuaj yeem ntes ntau yam khoom siv;
2. Siab rhiab heev;
3. Intuitive zaub, kev ua haujlwm yooj yim thiab tus nqi qis.
Qhov tsis zoo ntawm kev ntsuas kev nkag mus yog:
1. Nws tsis tsim nyog rau kev tshuaj xyuas cov khoom ua haujlwm ua los ntawm cov ntaub ntawv xoob xoob thiab cov khoom ua haujlwm nrog cov khoom ntxhib;
2. Kev ntsuam xyuas kev nkag mus tsuas tuaj yeem tshawb xyuas qhov kev faib tawm ntawm qhov tsis xws luag, thiab nws yog qhov nyuaj rau kev txiav txim siab qhov tseeb qhov tob ntawm qhov tsis xws luag, yog li nws yog qhov nyuaj rau kev ntsuas qhov ntsuas ntawm qhov tsis xws luag. Cov txiaj ntsig kev tshawb pom kuj tseem cuam tshuam los ntawm tus neeg teb xov tooj.
X-ray kuaj
Qhov kawg, kev kuaj pom hluav taws xob, yog vim X-rays yuav ploj tom qab dhau los ntawm cov khoom irradiated, thiab cov khoom sib txawv nrog cov thicknesses sib txawv muaj qhov sib txawv ntawm qhov nqus rau lawv, thiab cov yeeb yaj kiab tsis zoo yog muab tso rau sab nraud ntawm cov khoom irradiated, uas yuav txawv vim qhov sib txawv ray siv. Cov duab sib thooj raug tsim tawm, thiab cov neeg tshuaj xyuas tuaj yeem txiav txim seb puas muaj qhov tsis xws luag hauv cov khoom thiab qhov xwm txheej ntawm qhov tsis xws luag raws li daim duab.
Kev siv thiab kev txwv ntawm kev kuaj hluav taws xob:
1. Nws yog rhiab heev rau kev tshawb pom ntawm ntim-hom tsis xws luag, thiab nws yooj yim dua rau tus yam ntxwv ntawm qhov tsis xws luag.
2. Radiographic negatives yog ib qho yooj yim khaws cia thiab muaj traceability.
3. Visually tso saib cov duab thiab hom tsis xws luag.
4. Qhov tsis zoo yog qhov faus qhov tob ntawm qhov tsis xws luag tsis tuaj yeem nyob. Nyob rau tib lub sij hawm, nrhiav kom pom thickness yog txwv. Cov yeeb yaj kiab tsis zoo yuav tsum tau ntxuav tshwj xeeb, thiab nws muaj kev phom sij rau tib neeg lub cev, thiab tus nqi siab.
Tag nrho cov nyob rau hauv tag nrho cov, ultrasonic thiab X-ray flaw detection yog tsim nyog rau kev soj ntsuam sab hauv; ntawm lawv, ultrasonic yog haum rau qhov chaw nrog ib tug niaj hnub zoo li ntawm ntau tshaj 5 hli, thiab X-rays tsis tuaj yeem nrhiav qhov faus qhov tob ntawm qhov tsis xws luag thiab muaj hluav taws xob. Sib nqus particle thiab penetrant xeem yog tsim los xyuas qhov tsis xws luag ntawm cov khoom; ntawm lawv, kev ntsuam xyuas qhov sib nqus yog txwv rau kev kuaj xyuas cov khoom sib nqus, thiab kev ntsuas kev nkag siab tsuas yog txwv rau kev kuaj pom qhov qhib qhov tsis xws luag.
