Dab tsi yog qhov txawv ntawm cov khoom siv hlau thiab hlau-cored hlau?
Taw qhia:
Vuam yog cov txheej txheem siv dav hauv ntau yam lag luam, suav nrog kev tsim kho, tsheb, thiab kev tsim khoom. Nws koom nrog ob lossis ntau daim hlau ua ke los ntawm melting cov ntaub ntawv hauv paus thiab ntxiv cov khoom muab tub lim. Cov khoom muab tub lim, nyob rau hauv daim ntawv ntawm ib tug hlau, yog ib qho tseem ceeb rau kev ua tiav ib tug muaj zog thiab txhim khu kev qha weld. Muaj ntau hom vuam hlau muaj nyob rau hauv kev ua lag luam, tab sis ob feem ntau siv yog cov khoom siv hlau thiab hlau-cored hlau. Cov kab lus no tsom mus rau qhov sib txawv ntawm ob hom ntawm cov xov hlau no, suav nrog lawv cov muaj pes tsawg leeg, kev siv, qhov zoo, thiab qhov tsis zoo.
I. Kev sib xyaw
Khoom Hlau:
Cov khoom siv vuam hlau, tseem hu ua cov tub ntxhais hlau xaim lossis roj hlau arc vuam (GMAW) hlau, yog cov khoom siv hlau hlau uas muaj qhov sib txuam sib luag thoob plaws nws qhov ntev. Nws feem ntau yog ua los ntawm ib qho khoom siv, xws li cov hlau me me, stainless hlau, lossis txhuas. Txoj kab uas hla ntawm cov xaim tuaj yeem sib txawv nyob ntawm daim ntawv thov thiab cov yam ntxwv ntawm qhov xav tau weld.
Hlau-Cored Hlau:
Hlau-cored hlau, ntawm qhov tod tes, muaj ib lub hollow hlau sheath nrog ib tug flux core nyob rau hauv. Lub sheath yog ua los ntawm cov khoom siv sib xws rau lub hauv paus hlau yog welded, thiab cov tub ntxhais flux muaj ib qho kev sib xyaw ntawm cov ntsiab lus alloying thiab tshuaj. Cov ntsiab lus alloying txhim kho cov khoom siv ntawm cov vuam, thaum cov tshuaj tiv thaiv nws los ntawm oxidation thiab lwm yam tsis xws luag.
II. Daim ntawv thov
Khoom Hlau:
Cov hlau nplaum feem ntau yog siv rau hauv ntau yam txheej txheem vuam, suav nrog roj hlau arc vuam (GMAW) thiab flux-cored arc vuam (FCAW). Nws yog tsim rau ntau yam kev siv, xws li kev kho tsheb, kev tsim steel hlau, thiab kev tsim khoom. Cov khoom siv hlau yog ntau yam thiab tuaj yeem siv rau vuam sib txawv ntawm cov hlau, nrog rau cov hlau me, stainless hlau, thiab txhuas.
Hlau-Cored Hlau:
Hlau-cored hlau yog tsim tshwj xeeb rau kev kub ceev thiab kev siv vuam zoo. Nws yog feem ntau siv nyob rau hauv automated los yog robotic vuam txheej txheem, qhov twg precision thiab efficiency yog tseem ceeb heev. Hlau-cored hlau yog tsim rau vuam hnyav daim hlau thiab cov qauv, nrog rau cov ntawv thov uas xav tau kev nkag mus tob, xws li kev tsim cov nkoj, kev tsim choj, thiab kev tsim cov hlab ntsha.
III. Qhov zoo thiab qhov tsis zoo
Khoom Hlau:
Qee qhov zoo ntawm kev siv cov khoom siv hlau muaj xws li:
1. Yooj yim rau siv: Cov khoom siv hlau yog ncaj nraim los tuav thiab pub rau hauv cov khoom siv vuam.
2. Smooth arc yam ntxwv: Cov khoom siv hlau ua kom ruaj khov thiab zoo ib yam, uas ua rau muaj qhov huv thiab zoo sib xws.
3. Tsawg spatter: Cov hlau feem ntau ua rau tsis tshua muaj tawg thaum lub sij hawm vuam, txo qhov kev xav tau ntawm kev ntxuav tom qab vuam.
4. Tus nqi zoo: Cov khoom siv hlau feem ntau yog tus nqi ntau dua li cov hlau-cored hlau, ua rau nws xaiv rau ntau daim ntawv thov.
5. Muaj dav: Cov khoom siv hlau yog nkag tau rau hauv ntau txoj kab uas hla thiab cov khoom sib xyaw ua ke, ua rau nws siv tau rau cov kev xav tau sib txawv.
Txawm li cas los xij, cov khoom siv hlau kuj muaj qee qhov tsis zoo:
1. Tsawg deposition tus nqi: Khoom hlau nyhav kom muaj qis deposition tus nqi piv rau hlau-cored hlau, ua rau lub sij hawm vuam ntev.
2. Kev nkag mus tau yooj yim: Cov xaim hlau tsis tuaj yeem nkag mus tob npaum li cov hlau-cored hlau, ua rau nws tsis haum rau qee yam kev siv, xws li tuab phaj vuam.
Hlau-Cored Hlau:
Hlau-cored hlau muaj ntau qhov zoo dua li cov xaim hlau:
1. Cov nqi tso nyiaj ntau dua: Cov hlau-cored hlau ua rau cov vuam nrawm nrawm dua thiab cov nqi tso nyiaj ntau dua, ua kom cov khoom tsim tau.
2. Kev nkag mus tob dua: Hlau-cored xaim muab kev nkag tau zoo dua rau hauv cov hlau hauv paus, tso cai rau cov welds muaj zog thiab ruaj khov dua.
3. Txhim kho cov khoom siv kho tshuab: Cov khoom siv alloying hauv cov hlau-cored hlau txhim kho cov khoom siv ntawm cov vuam, xws li lub zog thiab kev cuam tshuam.
4. Txo cov cua sov nkag: Hlau-cored xaim tso cai rau cov cua kub qis dua thaum lub sij hawm vuam, uas yog qhov zoo rau kev tiv thaiv kev cuam tshuam thiab cov teeb meem kub ntxhov (HAZ).
5. Kev ua kom muaj zog ntxiv: Cov hlau-cored hlau txo qhov kev xav tau ntawm kev pib thiab nres ntau zaus thaum vuam vim kev noj tsis tu ncua, ua rau lub sij hawm thiab nqi txuag.
Txawm hais tias nws qhov zoo, cov hlau-cored hlau kuj muaj qee qhov kev txwv:
1. Kev teeb tsa nyuaj: Hlau-cored xaim yuav tsum muaj cov cuab yeej tshwj xeeb thiab tej zaum yuav muaj kev teeb tsa sib txawv piv rau cov khoom siv hlau.
2. Cov nqi siab dua: Cov hlau-cored hlau feem ntau kim dua li cov khoom siv hlau, feem ntau yog vim cov ntsiab lus alloying thiab flux core.
3. Txwv tsis pub muaj: Hlau-cored hlau tej zaum yuav tsis muaj dav li khoom hlau, tshwj xeeb tshaj yog nyob rau hauv me me diameters los yog tej yam compositions.
4. Ntau dua spatter: Hlau-cored hlau nyhav yuav tsim ntau spatter thaum vuam, yuav tsum tau ntxuav ntxiv tom qab vuam txheej txheem.
Xaus
Nyob rau hauv cov ntsiab lus, khoom hlau thiab hlau-cored hlau yog ob hom vuam hlau siv nyob rau hauv ntau yam kev siv. Cov khoom siv hlau yog ntau yam, siv tau yooj yim, thiab siv tau zoo, ua rau nws yog qhov kev xaiv nrov rau ntau qhov kev xav tau vuam. Ntawm qhov tod tes, hlau-cored hlau muab cov nqi tso nyiaj ntau dua, kev nkag mus tob dua, thiab txhim kho cov khoom siv kho tshuab, ua rau nws zoo tagnrho rau kev siv vuam ceev thiab zoo. Thaum xaiv cov khoom siv hlau thiab hlau-cored hlau, nws yog ib qho tseem ceeb uas yuav tau xav txog cov yam ntxwv xws li cov yam ntxwv ntawm cov vuam xav tau, cov ntawv thov yuav tsum tau ua, thiab cov nqi txiav txim siab.
