Kev tswj kom cov khoom siv siab ruaj khov yog qhov tseeb rau txhua tus tswv/tus neeg ua haujlwm. Cov tswv/tus neeg ua haujlwm ntawm cov khoom siv xws li cov hlab ntsha, cov cub tawg, cov boilers, cov khoom pauv, cov thoob cia khoom, thiab cov kav dej thiab cov cuab yeej cuam tshuam vam khom rau qhov kev tswj hwm kev ncaj ncees los ntsuas qhov kev ntseeg tau ntawm cov khoom siv thiab tiv thaiv qhov kev ncaj ncees ntawm cov khoom siv rau kev ua haujlwm zoo thiab muaj kev nyab xeeb. Ntau txoj hauv kev tsis ua puas tsuaj feem ntau siv los saib xyuas cov khoom tseem ceeb, vim tias kev nkag siab txog cov hlau zoo ntawm cov khoom no yog qhov tseem ceeb rau lawv qhov kev ntseeg tau thiab kev ua haujlwm zoo. Kev siv hom khoom tsis raug tuaj yeem muaj qhov tshwm sim tsis zoo.
Kev sim qee yam ntawm cov khoom no (xws li cov khoom me me lossis cov kav dej sib dhos) rau kev tshuaj xyuas cov pa roj carbon thiab cov qib khoom siv tuaj yeem nyuaj vim yog geometry lossis qhov loj me. Vim yog qhov nyuaj ntawm kev tshuaj xyuas cov khoom siv, cov khoom no feem ntau raug tshem tawm ntawm qhov kev pab cuam Positive Material Identification (PMI). Tab sis koj tsuas yog tsis tuaj yeem tsis quav ntsej txog cov ntu tseem ceeb, suav nrog cov kav dej me me. Ib qho khoom me me uas ua tsis tiav hauv lub kaw lus tseem ceeb tuaj yeem muaj qhov cuam tshuam zoo ib yam li qhov ua tsis tiav ntawm cov khoom loj dua. Cov txiaj ntsig ntawm kev ua tsis tiav yuav me dua, tab sis cov txiaj ntsig yuav zoo ib yam: hluav taws, lub sijhawm ua haujlwm ntawm cov nroj tsuag, thiab kev raug mob.
Vim tias Laser Induced Breakdown Spectroscopy (LIBS) tau hloov ntawm cov txheej txheem tshuaj ntsuam hauv chaw kuaj mus rau cov txheej txheem tseem ceeb, lub peev xwm los ua 100% ntawm qhov kev kuaj carbon uas xav tau ntawm txhua yam khoom hauv daim teb yog qhov sib txawv loj hauv kev lag luam uas nyuam qhuav tau sau los ntawm cov txheej txheem tshuaj ntsuam. Cov thev naus laus zis no ua rau cov tswv / cov neeg ua haujlwm tuaj yeem sim cov khoom no kom raug thiab raug rau cov txheej txheem khoom siv thiab muab cov kev daws teeb meem rau kev txheeb xyuas cov khoom siv hauv tsev suav nrog kev tshuaj ntsuam carbon.
Daim Duab 1. Kev Tshawb Fawb Txog Carbon ntawm SciAps Z-902 ER308L Weld ¼” Dav Qhov Chaw: SciAps (Nyem daim duab kom loj dua.)
LIBS yog ib txoj kev siv lub teeb ci uas siv lub laser pulsed los rhuav tshem qhov chaw ntawm cov khoom thiab tsim cov plasma. Lub spectrometer onboard ntsuas lub teeb ntawm cov plasma, cais cov wavelengths ib leeg los qhia cov ntsiab lus ntawm cov khoom, uas tom qab ntawd ntsuas los ntawm kev ntsuas onboard. Nrog rau cov kev tsim kho tshiab hauv cov handheld LIBS analyzers, suav nrog cov qhov me me tawm, ib qho chaw inert argon tuaj yeem ua tiav yam tsis tas yuav kaw cov nplaim nkhaus lossis cov khoom me me, ua rau cov kws kho tshuab tuaj yeem sim cov khoom tsis hais qhov loj me lossis geometry. Cov kws kho tshuab npaj cov chaw, siv cov koob yees duab sab hauv los tsom mus rau qhov chaw sim thiab tshuaj xyuas lawv. Thaj chaw sim yog kwv yees li 50 microns, uas yuav tso cai rau cov kws kho tshuab ntsuas cov khoom ntawm txhua qhov loj me, suav nrog cov khoom me me, tsis tas yuav tsum tau adapters, sau cov shavings, lossis xa cov khoom txi rau lub chaw kuaj mob.
Muaj ntau lub tuam txhab tsim cov tshuab ntsuas LIBS uas muaj nyob hauv khw. Thaum nrhiav cov tshuab ntsuas uas haum rau koj daim ntawv thov, cov neeg siv yuav tsum nco ntsoov tias tsis yog txhua lub tshuab ntsuas LIBS uas muaj tes yog tsim sib npaug. Muaj ntau tus qauv ntawm cov tshuab ntsuas LIBS hauv khw uas tso cai rau kev txheeb xyuas cov khoom siv, tab sis tsis yog cov pa roj carbon. Txawm li cas los xij, hauv cov ntawv thov uas xav tau qib khoom siv, carbon raug ntsuas thiab cov khoom siv raug ntsuas raws li qhov ntau ntawm carbon. Yog li ntawd, carbon yog qhov tseem ceeb rau kev tswj hwm kev ncaj ncees.
Daim Duab 2. Kev tshuaj xyuas carbon ntawm SciAps Z-902 ntawm 1/4-nti tshuab ntsia hlau, 316H khoom. Qhov chaw: SciAps (Nyem daim duab kom loj dua.)
Piv txwv li, 1030 carbon steel yog txheeb xyuas los ntawm cov ntsiab lus carbon hauv cov khoom siv, thiab ob tus lej kawg hauv lub npe khoom siv txheeb xyuas cov ntsiab lus carbon nominal - 0.30% carbon yog cov pa roj carbon nominal hauv 1030 carbon steel. Qhov no kuj siv rau lwm cov hlau carbon xws li 1040, 1050 carbon steel, thiab lwm yam. Lossis yog tias koj tab tom ntsuas 300 series stainless hlau, cov ntsiab lus carbon yog qhov tseem ceeb uas yuav tsum tau txheeb xyuas qib L lossis H ntawm cov khoom siv, xws li 316L lossis 316H khoom siv. Yog tias koj tsis ntsuas carbon, koj tsuas yog txheeb xyuas hom khoom siv thiab tsis yog qib khoom siv.

Cov tshuab ntsuas LIBS uas tsis muaj peev xwm ntsuas cov pa roj carbon tsuas yog tuaj yeem txheeb xyuas cov khoom siv, zoo ib yam li cov cuab yeej X-ray fluorescence (XRF). Txawm li cas los xij, ntau lub tuam txhab tsim cov tshuab ntsuas LIBS carbon uas muaj peev xwm ntsuas cov pa roj carbon. Muaj qee qhov sib txawv tseem ceeb hauv cov tshuab ntsuas xws li qhov loj me, qhov hnyav, tus lej ntawm kev ntsuas muaj, cov qauv interface rau cov nplaim kaw thiab tsis kaw, thiab nkag mus rau cov khoom me me rau kev ntsuas. Cov tshuab ntsuas LIBS nrog cov qhov tawm me me tsis xav tau lub foob argon rau kev sim, thiab tsis xav tau cov khoom siv hloov kho uas lwm cov tshuab ntsuas LIBS lossis OES xav tau los sim cov khoom siv. Qhov zoo ntawm cov txheej txheem no yog tias nws tso cai rau cov kws tshaj lij los sim txhua qhov ntawm cov txheej txheem PMI yam tsis tas siv cov khoom siv hloov kho tshwj xeeb. Cov neeg siv yuav tsum kawm ntau yam haujlwm ntawm lub tshuab ntsuas kom txiav txim siab seb cov cuab yeej puas tuaj yeem ua tau raws li qhov xav tau ntawm daim ntawv thov, tshwj xeeb tshaj yog tias daim ntawv thov xav tau 100% PMI.
Cov peev xwm ntawm cov cuab yeej LIBS uas siv tes tuav tau hloov txoj kev tswj hwm kev tshuaj xyuas thaj chaw. Cov cuab yeej no muab rau tus tswv / tus neeg ua haujlwm nrog txoj hauv kev los tshuaj xyuas cov khoom siv tuaj, cov khoom siv PMI uas siv hauv kev pabcuam / vintage, welds, cov khoom siv vuam, thiab txhua yam khoom tseem ceeb hauv lawv qhov kev pab cuam PMI, muab kev daws teeb meem zoo thiab txhim khu kev qha rau txhua qhov kev pab cuam kev ncaj ncees ntawm cov cuab tam. Kev daws teeb meem pheej yig yam tsis muaj kev ua haujlwm ntxiv lossis tus nqi ntawm kev yuav cov khoom siv lossis sau cov shavings thiab xa lawv mus rau chav kuaj thiab tos cov txiaj ntsig. Cov cuab yeej tshuaj xyuas LIBS uas siv tes tuav tau no muab rau cov neeg siv nrog cov haujlwm ntxiv uas tsis tau muaj ob peb xyoos dhau los.
