Yuav Ua Li Cas Pipe Weld Flaw Detection

Weld flaw detection testing yog dab tsi?

Weld flaw detection testing yog kuaj xyuas cov kab nrib pleb lossis qhov tsis xws luag hauv cov khoom siv hlau lossis cov khoom siv, tsis muaj tshuaj lom neeg hloov pauv, tsis muaj kev puas tsuaj. Kev kuaj xyuas qhov tsis zoo yog siv cov khoom siv acoustic, kho qhov muag, sib nqus thiab hluav taws xob ntawm cov khoom, thaum tsis muaj kev puas tsuaj lossis tsis cuam tshuam rau kev siv qhov kev ua tau zoo ntawm cov khoom yuav tsum tau sim nyob rau hauv qhov chaw ntawm qhov chaw kuaj xyuas thiab cov sab hauv zoo ntawm kev soj ntsuam ntawm ib tug txhais tau tias ntawm kev ntsuam xyuas kom paub tias muaj cov tsis xws luag los yog inhomogeneities nyob rau hauv cov khoom yuav tsum tau soj ntsuam.

Weld flaw detection soj ntsuam Scope:
1. kev soj ntsuam ntawm weld nto defects. Tshawb xyuas qhov chaw ntawm qhov vuam rau cov kab nrib pleb, tsis muaj welded thiab weld to thiab lwm yam teeb meem vuam.
2. Kev tshuaj xyuas sab hauv kab noj hniav. Txheeb xyuas qhov chaw ntawm cov kab nrib pleb, khawb, qhov, pob, tawv nqaij, kos kab, me ntsis, corrosion thiab lwm yam tsis xws luag.
3. Kev tshuaj xyuas ntau dhau. Xyuas seb puas muaj cov khoom seem sab hauv, cov khoom txawv teb chaws thiab lwm yam khoom siv ntau dhau hauv cov kab noj hniav sab hauv ntawm cov khoom.
4. Xeev daim tshev. Thaum qee yam khoom (xws li cab iav twj tso kua mis, cav, thiab lwm yam) ua hauj lwm, raws li cov kev cai ntawm qhov project teev nyob rau hauv lub endoscopy.

Txoj kev kuaj xyuas:
1. Kev nkag mus rau qhov tsis txaus ntseeg PT Kev ntsuas kev nkag mus yog tsuas yog siv rau kev kuaj tsis muaj kev puas tsuaj ntawm qhov qhib qhov tsis xws luag. Xws li cov kab nrib pleb, folds, cua qhov, txias cais thiab porosity. Nws tsis txwv los ntawm cov qauv thiab tshuaj lom neeg muaj pes tsawg leeg ntawm cov khoom. Nws tuaj yeem kuaj xyuas tsis yog cov khoom siv hlau nkaus xwb tab sis kuj tseem muaj cov ntaub ntawv tsis ntxeem tau xws li plastics, ceramics thiab iav.
Lub permeability zaub yog intuitive thiab yooj yim rau txiav txim. Txoj kev ua haujlwm yog ceev thiab yooj yim. Kev tsis xws luag hauv txhua qhov kev taw qhia tuaj yeem kuaj pom los ntawm kev ua haujlwm, tab sis muaj qee qhov kev txwv. Nws tsuas tuaj yeem tshawb xyuas qhov chaw qhib qhov tsis xws luag, thiab tsis tuaj yeem kuaj pom qhov tsis xws luag uas raug thaiv los ntawm cov kab mob los yog tau kho kho tshuab (polished, hauv av, thiab lwm yam) nrog kaw qhov qhib). Nws kuj tseem 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. Nws tus tsim tawm siv tau rau lub sijhawm soj ntsuam zoo ntawm 8-10 feeb. Thiab feem ntau nws tsis tuaj yeem siv tib lub sijhawm nrog kev sib nqus particle qhov tsis zoo; magnetic suspension thov los ntawm nws cov hmoov sib nqus yuav thaiv qhov qhib ntawm qhov tsis xws luag. Raws li cov kev cai tshwj xeeb, koj tuaj yeem ua qhov kev nkag mus rau qhov tsis txaus ntseeg ua ntej, thiab tom qab ntawd ua cov khoom sib nqus particle qhov tsis zoo, tab sis qhov kev kuaj pom yuav tsawg heev, tsis muaj qhov tseem ceeb.

2.Magnetic particle kuaj MT
Magnetic particle flaw detection yog tsuas yog siv los txheeb xyuas qhov chaw thiab qhov chaw ze ntawm qhov chaw nyob hauv cov pa roj carbon steel, alloy structural steel, nag lossis daus hardening steel thiab hluav taws xob hlau. Raws li cov khoom sib nqus tsis txuas ntxiv sib sau ua ke rau ntawm qhov chaw ntawm cov khoom kuaj xyuas, cov duab, txoj haujlwm thiab qhov loj ntawm qhov tsis sib xws tuaj yeem pom thiab lawv qhov xwm txheej tuaj yeem txiav txim siab. Lub rhiab heev ntawm kev sib nqus particle flaw detection kuj yog siab heev, thiab qhov dav ntawm qhov kuaj pom qhov tsis xws luag tuaj yeem ncav cuag 0.1 μm, thiab qee qhov tsis sib xws tau faus txog li ob peb millimeters lossis txawm tias kaum millimeters tuaj yeem kuaj pom.
Magnetic particle flaw detection yog zoo li unlimited los ntawm qhov loj thiab cov duab ntawm ib feem raug soj ntsuam, thiab siv ntau yam ntawm magnetisation cov tswv yim los xyuas txhua qhov tsis xws luag. Nws cov txheej txheem yog qhov yooj yim, kev soj ntsuam ceev ceev thiab tus nqi qis. Txawm li cas los xij, nws tsis tuaj yeem kuaj xyuas cov hlau tsis muaj hlau xws li txhuas, magnesium thiab tooj liab, thiab tsis tuaj yeem kuaj xyuas cov khoom tsis yog hlau xws li roj hmab, yas, iav thiab ceramics. Tsis tuaj yeem kuaj austenitic stainless hlau, feem ntau yog siv rau hull welds, diesel cav qhov chaw, steel forgings, cam khwb cia hlau qhov chaw tshuaj xyuas. Magnetic particle soj ntsuam tsuas yog siv rau cov ntaub ntawv ferromagnetic; tsuas yog kuaj xyuas qhov chaw thiab qhov ze ntawm qhov chaw; nws muaj peev xwm ua kom pom cov kab nrib pleb.
3.Ultrasonic flaw nrhiav pom
Ultrasonic flaw detection yog siv dav hauv kev lag luam, feem ntau yog siv rau forgings, dov qhov chaw, welds, castings thiab lwm yam. Muaj feem xyuam rau ferrous, non-ferrous thiab non-metallic cov ntaub ntawv thiab qhov chaw. Ultrasonic nthwv dej yog tsim rau kev kuaj lub dav hlau tsis xws luag, xws li tawg, folds, interlayers, unwelded, unfused thiab hais txog. Ntev npaum li lub nqaj ultrasonic yog perpendicular rau lub dav hlau tawg, lub siab tsis xws luag tuaj yeem tau txais. Txawm li cas los xij, nws tsis rhiab txaus rau qhov tsis xws luag xws li porosity slag, thiab cov hluav taws xob tsawg.
4.Ray teeb pom kev zoo
X-ray qhov teeb meem nrhiav pom yog ib qho ntawm cov ntxov tshaj plaws thiab feem ntau siv cov kev kuaj tsis muaj kev puas tsuaj. Lub hauv paus ntsiab lus yog ua raws li X-ray nkag mus ntawm cov khoom tom qab lub degree ntawm attenuation los txheeb xyuas qhov tsis xws luag hauv cov khoom, yog li ua qhov sib txawv blackness ntawm cov duab ntawm qhov tsis zoo. Cov duab tsis zoo yog intuitive thiab yooj yim los nrhiav qhov zoo thiab ntau. Nws muaj feem xyuam rau ntau yam ntaub ntawv xws li hlau thiab tsis yog hlau.
