Dab tsi yog CO2 vuam hlau?

Hauv kev teb ntawm Vuam niaj hnub, CO₂ vuam hlau yog cov khoom siv tshwj xeeb tsim rau kev siv cov pa roj hmab hauv Mig (cov roj hlau (hlau ua haujlwm) vuam cov txheej txheem. Nws cov tshuaj sib xyaw tshwj xeeb thiab cov qauv tsim muaj txiaj ntsig zoo, ua kom nws muaj kev lag luam zoo li kev lag luam xws li kev lag luam, thiab kev tsim khoom hnyav.
Cov Ntsiab Lus Txhais: Qhov kev txiav txim siab rau kev tiv thaiv
CO₂ VUAM HLAU yog ib qho khoom siv los yog flux - Cored hlau uas ua rau Arc ruaj khov thiab paired nrog koom nrog koom nrog kev tiv thaiv roj ruaj khov. Tsis zoo li Dav Dav - Lub Hom Phiaj Vuam hlau, nws yog engineered los daws cov yam ntxwv ntawm kev sib xyaw thiab cov arc lub zog me me.
Khoom Siv Hluav Taws Xob Vuam (piv txwv li, Aws Er70s - 6) yog cov ntawv thov kev lag luam. Lawv muaj cov deagidizing xws li silicon, manganese, thiab qee zaum titanium, uas neutraling oxygen tso los ntawm sib tw. Qhov no tiv thaiv oxide paug nyob rau hauv weld, ua kom muaj zog thiab kev sib txawv. Flux-cored Coro xov hlau, txawm tias tsawg dua, ua ke tiv thaiv deoxidizing zoo sib xws, txhim kho ib leeg nyob ib leeg yuav tawm tsam kom tiv thaiv weld cheeb tsam.
Cov yam ntxwv tseem ceeb: Vim li cas nws ua haujlwm nrog COU
Cov kev ua tau zoo ntawm CO₂ vuam hlau stags los ntawm peb qhov tseem ceeb nta uas tau dlhos nrog cov shooter tiv thaiv:
Oxidation tsis kam
Co cais tawm rau hauv oxygen thiab carbon monoxide ntawm vuam kub, uas yuav txwv tsis pub ua me ntsis oxides hauv Weld. Cov silicon thiab manganese nyob rau hauv co₂ vuam hlau rov qab los nrog oxygen ua ntej, ua kom muaj kev phom sij hauv cov nplais (lossis raug ntiab tawm), tawm hauv weld hlau huv thiab muaj zog. Piv txwv li, hauv Carbon Steel Vuam, cov tshuaj tshuav no tiv thaiv kev tsim ntawm hlau oxide (feo), uas tsis muaj zog welsds.
Arc ruaj khov
CO₂ lub siab thermal conductivity tuaj yeem ua rau arc qhov tsis txaus ntseeg hauv cov xov hlau generic, ua kom muaj kev sib luag thiab tsis sib xws. Co₂ Vuam hlau yog tsim nrog meej alloy ratios kom ruaj khov arc. Manganese, piv txwv li, txhim kho arc txuas ntxiv, thaum cov kab lus zoo li txhuas kho cov arc ua kom pom tseeb thiab ua kom muaj kuab kauj ruam du.
Kev sib xyaw nrog cov tswv yim kub
CO₂ ua rau lub tsheb kub dua sib cav dua Argon - Raws roj, uas nce nkag tab sis kev pheej hmoo hlawv los ntawm cov ntaub ntawv nyias nyias. CO₂ VUAM HLAU MUAB YEEJ Qhov no ua rau nws haum rau vuam tuab carbon hlau daim hlau (1/4 nti thiab saum toj no) uas yuav tsum tau sib sib zog nqus.
Cov hom co₂ vuam hlau: khoom vs. Flux - cored
Co₂ Vuam cov xov hlau tau catalorized los ntawm cov qauv, txhua tus haum rau cov ntawv thov tshwj xeeb:
Cov Khoom Siv Hluav Taws Xob Vuam Hlau
Cov hom siv dav tshaj plaws, cov xov hlau cov khoom siv tag nrho ntawm kev sib xyaw (lossis lom}} argon sib xyaw) rau kev thaiv. Lawv ua kom zoo nyob rau hauv high- ceev, automatic welbotive lub cev sib dhos thiab tawg yog qhov tseem ceeb. Lawv txoj kev du ceev kom cov hlau uas tsis cuam tshuam los ntawm Mig phom, txo qis qis ntawm jams. Cov xov hlau cov khoom siv tau zoo rau cov chaw huv thiab sab hauv tsev uas muaj kev thaiv kev ua haujlwm tseem zoo.
Flux - cored co₂ vuam hlau
Cov hlau no sib xyaw ua ke hlau nrog cov qauv flux uas nthuav tawm cov roj av ntxiv thaum ua kom sov. Lawv nyiam rau sab nraum zoov lossis cua txias (piv txwv li, kev tsim kho chaw) qhov twg sib koom nrog ib leeg ib leeg yuav cuam tshuam. Flux Qaum 补充 (cov tshuaj ntxiv) CO₂ cov kev tiv thaiv, thaum nws tus kws lij choj deoxidizing txhim kho kev ncaj ncees rau Weld Kev Ncaj Ncees. Flux - Cored Co₂ hlau kuj tseem siv rau tuab {6}
Cov Ntawv Thov: Qhov chaw co kom muaj hlau ntsa
Co₂ Vuam hlau yog qhov tseem ceeb hauv cov xwm txheej ua ntej tus nqi, ceev, thiab Carbon Hlau sib haum:
• Txheej txheem steelrice: vuam kuv {{{{Beams, thiab cov qauv hlau ua kom muaj zog, thiab cov qauv phom) nrog qhov tsis xws luag.
• Cov kab lag luam: cov kab kaw lus siv cov xov hlau khoom siv weld chassis cov khoom siv, kev sib zog ua kom muaj kev ua haujlwm ntau dua.
• Kev siv tshuab hnyav: flux - cored bolbon steel seem (piv txwv li lawv cov kev tiv thaiv kev muaj zog tiv thaiv Tas khw.
• Cov Piping Systems: Rau cov kav dej steel hauv cov kav dej hlau lossis roj thiab roj av thiab roj vuam hlau ua ke nrog txaus siab tsis kam.
Qhov Zoo Dua Lwm Cov Hlau Vuam
Piv rau cov xov hlau tsim rau kev sib cav lossis sib xyaw roj av, coing vuam hlau muaj cov txiaj ntsig sib txawv:
• Nyiaj tau zoo: CO₂ roj yog qhov pheej yig dua Argon Blends, thiab cov xov hlau tsis tshua muaj nqi los tsim ntau tshaj alloys (piv txwv li, stainless hlau xaim). Qhov no txo ​​qhov kev txiav txim siab tag nrho vuam los ntawm 20-30% rau siab- ntim cov phiaj xwm.
• Kev tsim khoom zoo: nws ruaj khov Arc thiab comprans enlatibility nrog siab mus ncig ua si nrawm (txog 60 nti ib feeb) nce cov zis ntau ntxiv.
• Cov versatility hauv cov hlau hlau: Thaum tsis muaj peev xwm rau cov hlau tsis haum: nws outperforms lwm cov xov hlau vuam, ntsuas lub zog thiab yooj yim ntawm kev siv.
Qhov zoo tshaj plaws kev coj ua rau kev siv co₂ vuam hlau
Txhawm rau kom ua tau zoo, ua raws cov lus qhia no:
• Match hlau rau cov khoom siv: Siv ER70s-} 6 (lossis sib npaug) rau cov hlau me; Zam kev siv cov xov hlau rau cov hlau stainless lossis txhuas, raws li lawv tsis muaj cov tshuaj corrosion-resistant alloys.
• Txhim kho cov ntaub thaiv cov pa roj: ntshiab ua haujlwm rau cov ntaub ntawv tuab, thaum thib ib / 20% sib dhos txo cov ntawv rau cov ntawv sau cia lossis pom cov ntawv pom.
• Tswj cov hlau pub kom ceev: nrawm dua ib qho pub rau kev sib tshooj; qeeb dhau ua rau underfill. Calibrate pub tus nqi kom phim amperage (feem ntau 200-350 amps rau 0.035-0.045-nti xaim).
• Tswj cov cuab yeej siv cov khoom siv: khaws cov hlau pub rau yob kom txhob muaj cov lus qhia tsis tu ncua, thiab hloov cov lus qhia tsis tu ncua kom ntseeg tau tias hloov chaw tam sim.
Xaus: Ib qho cuab yeej tshwj xeeb rau CO₂ Shield Vuam
Co₂ Vuam xaim yog lub hom phiaj - tsim tau cov roj uas tsis muaj peev xwm tiv thaiv roj hauv Mig / Mag Vuam. Los ntawm kev tawm tsam co₂ tus oxidizing cov khoom, thiab ua kom muaj zog ntawm cov hlau, thiab ua kom muaj zog, thiab ua tau zoo} Txawm hais tias nyob rau hauv automated factories lossis kev kho kom haum, nws lub peev xwm ua rau muaj kev cuam tshuam nrog kev tiv thaiv nws lub luag haujlwm ua ib qho kev koom nrog cov khoom lag luam qub.
