Kev ua tau zoo yog lub neej ntawm kev lag luam, kev nrhiav kev ua tau zoo tshaj plaws yog los ua kom tau raws li qhov xav tau ntawm cov neeg siv khoom, txhua yam khoom siv zoo yog muaj zog lav.
Steel qauv
1. Tag nrho cov khoom siv hlau yuav tsum raug tshuaj xyuas los ntawm cov kws tshaj lij QC ua ntej khaws cia. Xws li: cov khoom siv, qhov loj me, teeb tsa, qhov hnyav thiab qhov sib txawv tau tso cai. Lub teb chaws tus qauv: GB/T700-2006, GB/T 709-2006, GB/T3274-2007, GB/T1591-2008.
2. Txhua daim ntawv weld groove, qhov loj me, cov khoom siv vuam yuav tsum nruj me ntsis raws li cov txheej txheem vuam specification thiab daim ntawv qhia dav dav; Thiab xyuas kom cov vuam zoo, cov khoom kuaj muaj xws li: kev kuaj pom, kev kuaj tsis muaj kev puas tsuaj (kev kuaj hluav taws xob, kuaj ultrasonic, kuaj, ntsuas qhov sib nqus sib nqus) thiab lwm yam. Kom paub meej cov vuam tsim nyog xa mus rau lub teb chaws tus qauv ntawm: GB / T {{1} }, JB/T10559-2006, thiab JB/T6062-2007.
Cov nram qab no xya feem ntau siv:
1. RT: Kev kuaj hluav taws xob
2. UT: Kev Ntsuas Ultrasonic
3. PT: Kev xeem nkag
4. MT: Sib Nqus Particle Test (Magnetic Testing)
5. THIAB: Electromagnetism lossis Eddy tam sim no Test
6. Kev ntsuam xyuas txheej
Hlau Hardness Test
Kev ntsuas hluav taws xob (RT)
X ray, Y ray lossis neutron ray xeem cov khoom tsis raug, thiab qhia cov duab ntawm cov ntaub ntawv nruab nrab los tshuaj xyuas nws sab hauv. Qhov kev sim no ncaj qha tab sis kim.
Kev kuaj ultrasonic (UT)
Siv ultrasonic los xyuas nws qhov tsis xws luag, qhov no yog qhov tsim nyog rau kev kuaj xyuas cov khoom siv hlau, qhov tsis xws luag sab hauv. Nws feem ntau yog siv rau cov yeeb nkab, phaj, bar thiab vuam; Qhov kev xeem yog ceev ceev, tus nqi qis, thiab daim ntawv thov dav.
Kev xeem nkag (PT)
Kev ntsuam xyuas Penetrant yog ua los ntawm kev siv lub penetrant, tshem tawm ntau dhau nrog lub tshuab ntxhua khaub ncaws, thiab yog tias tsim nyog, thov tus tsim tawm kom tau txais qhov qhia txog qee yam tsis xws luag ntawm qhov qhib rau saum npoo.
Magnetic Test (MT)
Siv cov hlau nplaum sib nqus thiab qhov kev ntsuam xyuas tsim nyog kom pom qhov tsis sib xws ntawm qhov chaw kuaj thiab ze ze.
Sib Nqus Particle Test (ET)
Magnetic particle testing yog ib qho kev sim uas tsis muaj kev puas tsuaj uas siv cov hlau nplaum sib nqus thiab qhov nruab nrab ntawm qhov ntsuas kom pom qhov tsis sib xws ntawm qhov chaw thiab nyob ze ntawm qhov chaw xeem.
Kev ntsuam xyuas hluav taws xob (eddy tam sim no) yog ib qho kev sim uas tsis muaj kev puas tsuaj uas yog siv rau cov eddy tam sim no hauv daim ntawv xeem (qhov cuam tshuam tam sim no tsim rau ntawm tus neeg xyuas pib thiab ze rau ntawm qhov chaw vim qhov hloov pauv ntawm sab nraud magnetic teb nyob rau hauv lub sij hawm los yog qhov chaw. ), thiab txheeb xyuas cov ntaub ntawv zoo ntawm daim ntawv xeem.
Kev ntsuam xyuas txheej
Txhawm rau kom ntseeg tau tias cov txheej txheem zoo, txheej txheej zaj duab xis kev ua haujlwm feem ntau suav nrog cov khoom siv kho tshuab (xws li thickness, adhesion, gloss, thiab lwm yam) thiab cov khoom tshwj xeeb (xws li corrosion resistance, oil resistance, acid resistance, etc.) .
Cov ntsuas ntsuas muaj xws li: txheej thickness tester, tester, adhesion tester, zaj duab xis gridding instrument, thiab lwm yam.
Kev kuaj hlau hardness
Feem ntau siv txoj kev ntsuas zoo li qub, xws li HB, HRC, HV, HL.HB thiab HRC yog cov qauv tseem ceeb thiab siv ntau dua. HB yog dav siv, HRC yog tsim rau saum npoo siab hardness cov ntaub ntawv, xws li kev kho cua sov hardness, thiab lwm yam., los xyuas cov hlau cov ntaub ntawv muaj peev xwm kuj los ntawm cov khoom tawv.
Cov khoom saum toj no Tsis muaj qhov hu ua ntu ntawm kev tshawb nrhiav, nws tau ua nrog rau cov txheej txheem ua haujlwm. Tsis muaj laj thawj los ua qhov tsis txaus ntseeg tom qab lub crane tsim, thiab koj tuaj yeem hais tias nws tsis tsim nyog yam tsis muaj kev tshuaj xyuas! Ntawd yog, txhua qhov txheej txheem yog ntsuas.
Nco tseg:Nws tsis tuaj yeem ua qhov kev sim ib los ntawm ib qho, uas yog kim heev thiab tsis muaj tseeb (lub sijhawm yuav tsum tau muaj, cov nqi yuav tsum tau muaj, cov neeg ua haujlwm xav tau, cov khoom siv kuaj, thiab chaw ua haujlwm yog tag nrho cov txwv). Hauv kev tsim khoom loj, qhov chaw raug tshuaj xyuas random, thiab muaj cov kev tshawb fawb tshwj xeeb.
