CO₂ gas shielded vuam tuaj yeem muab faib ua tsis siv neeg thiab ib nrab- tsis siv neeg vuam raws li txoj haujlwm ua haujlwm, thiab ua kom zoo- hlau thiab tuab- hlau vuam raws li txoj kab uas hla siv. Zoo- hlau welding siv ib txoj kab uas hla ntawm txoj kab uas hla tsawg dua 1.6 hli thiab haum rau nyias- phaj vuam. Thick-wire welding siv txoj kab uas hla ntawm 1.6 hli lossis siab dua thiab haum rau nruab nrab- mus rau{11}} tuab phaj vuam.
Qhov zoo: CO₂ gas shielded vuam muaj ntau yam txiaj ntsig piv rau shielded hlau arc vuam (SMAW) thiab submerged arc vuam (SAW).
(1) High welding productivity
Nyob rau hauv CO₂ roj shielded vuam, qhov tam sim no ceev yog siab, lub melting ceev ceev, thiab tsis tas yuav tsum tau slag tshem tawm thaum lub sij hawm vuam txheej txheem. Nws cov khoom tsim tau yog 2 mus rau 4 npaug siab dua li ntawm SMAW zoo tib yam.
(2) Tsawg vuam distortion
Vim muaj qhov ceev tam sim no, muaj zog arc cua sov, nqaim cua sov cheeb tsam, thiab cov nyhuv txias ntawm CO₂ roj, vuam distortion yog tsawg. Qhov no tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau nyias - phaj vuam, vim nws txo qhov kev xav tau ntawm kev hloov pauv hloov.
(3) Tsawg rhiab heev rau roj thiab xeb
CO₂ gas decomposes ntawm qhov kub thiab txias, ua rau muaj zog oxidizing nyhuv, ua rau nws tsis tshua muaj rhiab heev rau roj, xeb, thiab lwm yam kab mob ntawm lub workpiece. Yog li ntawd, ua ntej-welding yuav tsum tau ua tsis nruj; tsuav yog tsis muaj qhov pom tseeb daj xeb, kev tu feem ntau tsis tsim nyog.
(4) Tsawg hydrogen cov ntsiab lus hauv vuam
Lub shielding gas muaj zog oxidizing zog ntawm qhov kub thiab txias, uas ua rau nws muaj siab affinity rau hydrogen, yog li txo cov hydrogen ntsiab lus nyob rau hauv vuam thiab tiv thaiv hydrogen porosity. Tsis tas li ntawd, qhov kev nyiam rau qhov txias txias yog qis dua thaum vuam qis - alloy siab - lub zog steels.
(5) Zoo arc visibility thiab ua haujlwm yooj yim
Lub arc hauv CO₂ gas shielded vuam yog qhov pom tau zoo, ua rau nws yooj yim rau taw thiab saib xyuas qhov vuam. Cov txheej txheem yog yooj yim rau kev khiav lag luam thiab yooj yim kawm, simplifying welder kev cob qhia.
(6) Tus nqi qis
CO₂ roj yog dav siv, pheej yig, thiab siv hluav taws xob tsawg dua vuam, ua rau tus nqi qis. Feem ntau, tus nqi ntawm CO₂ gas shielded vuam yog 40% -50% ntawm SMAW.
Qhov tsis zoo
(1) Qhov tseem ceeb spatter thiab tsis zoo rau saum npoo
Yog tias qhov vuam tsis raug xaiv kom raug, qhov sib tsoo tuaj yeem ua rau muaj kev cuam tshuam ntau, nce tom qab- vuam ua haujlwm. Txawm li cas los xij, thaum xaiv cov kev txwv kom raug, cov spatter uas tsim muaj tsawg dua li cov vuam nrog cov electrodes hauv SMAW. Yog li ntawd, qhov no tsis suav hais tias yog ib qho teeb meem loj.
(2) Nrhav arc teeb
Lub teeb arc hauv CO₂ gas shielded vuam yog qhov muaj zog heev, yuav tsum tau txhim kho kev tiv thaiv tus kheej thaum ua haujlwm.
(3) Tsis zoo cua tsis kam
Thaum ua haujlwm CO₂ gas shielded vuam sab nraum zoov, yuav tsum muaj kev tiv thaiv cua.
(4) Kev hloov pauv yooj yim
Lub vuam teeb thiab xaim pub hose yog qhov hnyav, ua rau kev ua haujlwm tsis yooj yim rau hauv qhov chaw kaw -tshwj xeeb tshaj yog thaum siv dej- txias taws. Tsis tas li ntawd, lub laub- hom xaim pub hose muaj qhov ntev ntev, feem ntau nyob ib ncig ntawm 3 meters, uas ua rau muaj qee yam kev txwv thaum vuam loj workpieces.
(5) Ntau yam ntawm cov khoom siv weldable
CO₂ gas shielded vuam siv tsis tau rau stainless hlau los yog yooj yim oxidized non{0}}ferrous hlau.
(6) Cov cuab yeej siv vuam sib txawv
Cov khoom siv rau CO₂ gas shielded welding yog qhov nyuaj tshaj qhov uas rau arc vuam, nrog tus nqi siab dua thiab cov kev xav tau ntau dua rau kev tu cov cuab yeej.
Elec Barrel tau cog lus tias yuav muab cov neeg siv khoom zoo siab - zoo, qis- cov thawv ntim khoom pov tseg thiab cov kev daws teeb meem pov tseg, ua rau nws txoj kev mob siab rau kev tiv thaiv ib puag ncig thoob ntiaj teb.
