Metallographic Testing: Dab tsi yog nws xyov?
Hauv cov ntsiab lus yooj yim, kev kuaj metallographic yog zoo li ua cov kev kho mob meej "-}} mus" ntawm cov hlau. Los ntawm kev ua kom muaj cov meticly state - Kuv npaj {{4} Zoo li kev kuaj xyuas hauv qab lub siab- powered tsom. Cov txheej txheem no qhia tawm cov qauv hlau sab hauv, suav nrog nws cov qauv siv lead ua, theem theem, grain loj, thiab ntau yam muaj peev xwm. Nws tso cai rau peb saib dhau ntawm qhov chaw du thiab kev pom rau cov khoom siv "sab hauv kev zoo nkauj" thiab kev noj qab haus huv.
Ntsuas cov txheej txheem tsim khoom lag luam zoo:
Rau siab - zaus welded (HFW) Lub Hlaib Zoo:
Metallography yog tusTus qauv kub rau kev ntsuas weld zoo. Nws ncaj qha ntsuas cov Txoj Kev Sib Koom TesthiabNkag tob,Ua kom cov khoom siv metallurgical ntawm lub fin thiab lub hauv paus tube, tsis yog tsuas yog cov tshuab ua haujlwm nplaum. Tus nqi sib cog lus zoo ncaj qha txhais kom muaj kev hloov kho cua sov siab dua thiab kev co.
Rau kev muaj tsawg tsawg -} Cov leeg tau zoo:
Kev txheeb xyuas rau micro - cov kab nrib pleb lossis tsis xws luag qhia thaum lub sij hawm yob, ua kom muaj kev ntseeg siab txheej txheem.
Xyuas cov xwm txheej cua sov:
Rau cov ntaub ntawv zoo li stainless hlau, tsim kom haum rau kev kho lossis annealing yog qhov tseem ceeb rau corrosion tsis kam. Metallography tuaj yeem qhia cov teeb meem xws li carbide nag lossis daus vim yog kev kho kom sov, tiv thaiv kev txhim kho yav tom ntej.
Ua kev soj ntsuam hauv paus hauv paus:
Yog tias lub raj tsis ua haujlwm hauv kev pabcuam, kev tshuaj ntsuam xyuas cov duab yog cov teeb meem ntsuas siv los ua qhov teeb meem hauv paus ua ke (piv txwv li cov txheej txheem tsis zoo, cov khoom tsis raug).
Peb Daim Hlau Hlau Ntsuas Kev Xyaum: Cov Pov Thawj Koj tuaj yeem pom
Peb ntseeg tias tsis zoo yog tsis yog lus slogan tab sis ntsuas tau, cov ntaub ntawv pov thawj. Hauv peb hauv {-} Lub tsev kuaj mob, peb tau ua haujlwm tshaj tawm cov tshuab ntaus ntawv thiab cov duab tsom xam cov kev ntsuas ntawm cov khoom lag luam tseem ceeb thiab cov txheej txheem.
Peb cov khoom ntsuas tshwj xeeb suav nrog:
Tsevneeg Nyiaj Txiag & Penetration Kev Ntsuas Qhov tob:
Quantifying weld quality to ensure a high standard of >85% Bonding tus nqi.
01
Grain loj Ntsuas Ntsuas:
Kev tshuaj xyuas cov nyom loj; Finer, ntau cov khaub ncaws hnav ntau dua feem ntau qhia tau zoo dua cov khoom siv zoo dua thiab cov plaw.
02
Cov Kev Ntsuam Xyuas (
Ntsuas cov hom, qhov loj me, thiab faib tawm ntawm tsis - nws yog xim hlau suav (piv txwv li, oxides), ntsuas cov khoom siv kev coj dawb huv.
03
Microstructure pov thawj:
Kev lees paub cov ntaub ntawv ua pov thawj cov qauv Austenitic, Ferritic qauv, thiab lwm yam, tsis muaj teeb meem, Sigma theem) nag lossis daus.
04
Txheej / Plating Thickness & Adhesion Kuaj (yog tias muaj cai):
Ua kom oveuring anti -} corrosion txheej yog niaj hnub zoo nkauj thiab zoo- adhered.
05
Daim ntawv tshaj tawm kev tshaj lij hlau yog qhov kev qhia paub, tab sis tsom mus rau ob peb lub ntsiab lus tseem ceeb qhia cov ntsiab lus tseem ceeb:
01
"Metallurgical Bond":
Nov yog lo lus uas koj xav pom tshaj plaws. Nws txhais tau tias lub fin thiab raj yog fused ntawm theem atomic.
02
"Bonding Rate: >Xx% ":
Qhov ntau dua feem pua, qhov zoo dua. Peb ib txwm siv zog rau qib zoo ntawm 85% -100%.
03
"Tsis muaj kab nrib pleb, tsis muaj qhov tsis tiav fusion":
Qhia cov txheej txheem tsim suab ua haujlwm pub dawb ntawm cov tsis xws luag.
04
"Zoo grain loj loj":
Kos npe rau cov khoom lag luam zoo dua.
Daim ntawv tshaj tawm yuav suav nroghigh - Txhais cov lus txhais cov micraphs, muab cov pov thawj pom tseeb.
Xaiv cov leeg uas tau txais rau kev sim phom sij ntawm daim duab ntsuas hluav taws xob txhais tau tias koj tau nqis peev tsis yog hauv cov khoom lag luam, tab sis hauv:
Siv sijhawm ntev dua lub neej:
Ib lub zog sab hauv cov qauv thiab cov kev tiv thaiv sab hauv siab tiv thaiv qhov kev pabcuam kev pabcuam ntawm cov tub sov ua kom sib haum.
Ntau dua hloov cua sov hloov efficiency:
Tus nqi ua tau zoo kawg nkaus uas ua kom muaj cov thermal zoo tshaj plaws, txo hluav taws xob kev siv hluav taws xob.
Txo Nqi & Kev Txij Nkawm Cov Nqi:
Minimizes qhov kev pheej hmoo ntawm kev npaj txhij txog downtime, kev poob ntau dua, thiab hloov cov nqi / kho cov nuj nqis vim kev ua tiav ntxov.
Peb tau cog lus los tswj cov khoom kom zoo rau txhua qhov me me. Yog xav paub ntau dua lossis thov peb cov ntawv qhia cov qauv qauv, thov koj xav tiv tauj peb pab pawg neeg. Cia peb siv cov ntaub ntawv tshawb fawb los muab kev thaj yeeb nyab xeeb rau koj.
