Roj vuam thiab hluav taws xob vuam yog ob txoj kev vuam, txhua tus nrog cov ntsiab lus sib txawv, cov cuab yeej siv, thiab kev siv. Nkag siab txog lawv qhov sib txawv los xaiv cov txheej txheem raug rau txoj haujlwm, vim tias lawv txawv rau kev ua haujlwm, precision, thiab kev haum xeeb rau cov khoom sib txawv thiab ib puag ncig.
Tub Ntxhais Ua Haujlwm
Qhov ntau tshaj plaws sib txawv lus dag nyob rau hauv yuav ua li cas lawv tsim kom muaj cua sov kom yaj. Roj av vuam nyob rau kev sib txuas ntawm cov roj roj (feem ntau acetylene, propane, lossis nkev) tov nrog oxygen. When ignited, this mixture produces a high-temperature flame-reaching up to 3,100℃for acetylene-oxygen combinations-that melts the base metal and filler material (if used), allowing them to fuse as they cool. Cov txheej txheem tsis tas yuav muaj hluav taws xob, ua rau nws ywj siab ntawm cov khoom siv hluav taws xob.
Hluav taws xob vuam, los ntawm kev sib piv, siv hluav taws xob los ua kom kub. Nws ua kom muaj hluav taws xob arc nruab nrab ntawm lub electrode (txawm yog cov xaim xaim los yog tsis - Consumable tungsten pas nrig) thiab workpiece. Lub arc, uas tuaj yeem ncav cuag qhov kub tshaj 5,000 degree, melts cov hlau ntawm kev sib koom tes. Daim ARC no tau txhawb nqa los ntawm hluav taws xob tam sim no (ib qho ntxiv tshiab, AC, lossis ncaj qha tam sim no, DC) uas los ntawm lub tshuab vuam muag ntawm lub zog.
Cov cuab yeej xav tau
Roj av vuam yog qhov yooj yim thiab portable. Nws suav nrog cov roj thooj voos kheej kheej (ib qho rau roj roj thiab ib qho rau cov pa roj teeb kom sib xyaw thiab cov hoses txuas cov thooj voos kheej kheej mus rau lub voos. Yuav siv cov pas nrig muab rau cov tub rog ntxiv rau cov khoom siv rau Weld, tab sis lawv tsis tsim nyog. Qhov tsis muaj cov hluav taws xob nyuaj ua rau lub teeb ci ntsa iab thiab kev thauj mus los yooj yim, txawm tias qhov xav tau cov roj cylinder ntxiv ntxiv qee qhov.
Fais vuam yuav tsum muaj lub zog hluav taws xob yuav tsum muaj lub zog hluav taws xob -}}}}} Xav tau cov khoom siv hluav taws xob theem siab rau lub arc. Cov khoom siv tshwj xeeb sib txawv los ntawm hom: MIG (hlau inert roj) vuam siv cov roj hmab pub khoom siv (feem ntau); Tig (tungsten inert roj) vuam siv ib qho tsis- consumable tungsten elegsten electrode thiab ib tug pas nrig cais; Pas vuam (smaw) siv cov fluinable flux {}}} coated electrode. Cesles txuas lub tshuab rau lub tshuab ua haujlwm (hauv av clamp) thiab qee hom hluav taws xob thooj voos kheej kheej rau kev thaiv, ntxiv rau cov khoom siv nyuaj.
Cov khoom siv tau sib xws
Roj vuam yog qhov ua tau zoo tshaj plaws rau nyias, qis}}} cov hlau carbon, raws li tsis yog tooj liab, tooj dag, thiab txhuas. Nws cov lus qhia kub qis dua thiab cov cua sov ua kom muaj cua sov txo cov kev pheej hmoo ntawm cov ntaub ntawv nyias nyias, thiab cov nplaim taws tuaj yeem hloov kho tau yooj yim kom phim rau cov hlau melting pot. Txawm li cas los xij, nws tawm tsam nrog siab- lub zog steels lossis cov kab tuab, zoo li cov nplaim hluav taws xob, uas yog cov nplaim taws ua kom muaj cua sov txaus.
Fais vuam yog ntau ntau ntau yam ntawm cov ntaub ntawv. Mig vuam ua haujlwm tau zoo rau cov steel hlau, hlau steel, thiab txhuas (nrog cov roj tiv thaiv hluav taws xob zoo); Tig Vuam excels ntawm precision ua haujlwm ntawm txhuas, titanium, thiab kab txawv alloys; Pas vuam thaiv cov cuab yeej siv cov hlau tuab thiab txawm tias cov hlau qias neeg. Qhov ntau dua kev siv hluav taws xob ntawm hluav taws xob arcs tso cai rau kev nkag kom tob, ua rau nws muaj zog) thiab ntau dua} lub zog vuam uas muaj zog vuam tsis tuaj yeem ntseeg tau tsis tau.
Precision thiab Control
Roj vuam muaj ntau dua kev tswj hwm cov lus qhia tshav kub, raws li welders tuaj yeem kho cov nplaim taws thiab siv hluav taws xob tswj hwm. Qhov no ua rau nws zoo tagnrho rau cov txiaj ntsig zoo li cov hniav nyiaj hniav kub zoo li cov hniav nyiaj hniav kub zoo li cov hniav nyiaj hniav kub, lossis koom nrog nyias cov ntawv sib xyaw ua ke tiv thaiv kev hlawv kub {}}} los ntawm. Txawm li cas los xij, lub zog qeeb cov txheej txheem tuaj yeem ua rau muaj ntau qhov distortal nyob rau hauv cov chaw ua haujlwm loj dua, thiab ua tiav kev nkag mus rau hauv tuab hlau yog qhov nyuaj.
Fais vuam muab cov ntawv hluav taws xob ua kom muaj tseeb nyob hauv cov ntawv thov muaj feem ntau. Cov tshuaj tiv thaiv cua sov ntawm lub arc tso cai rau nqaim weld hlaws dai thiab ntxaum, ntau yam kev nkag mus. Tig vuam, tshwj xeeb, muaj qhov tshwj xeeb tswj- cov kab ke tuaj yeem tsim cov pob qij txha huv si, ua kom pom kev xaiv rau kev kho mob lossis khoom siv kho mob. Mig vuam, nrog nws cov hlau ntsuas tshuab xaim hluav taws xob, muab cov txiaj ntsig zoo ib yam hauv kev tsim cov loj, txo cov neeg yuam kev.
Ib puag ncig thiab kev txwv
Roj vuam yog zoo -}} haum rau sab nraum zoov lossis chaw deb, vim nws tsis tas yuav muaj hluav taws xob. Nws ua tau ntseeg nyob rau hauv cov kev mob siab tshaj plaws (nrog rau cov txheej txheem hluav taws xob tsim nyog) thiab feem ntau yog kho cov cuab yeej ua liaj ua teb lossis cov qauv hlau hauv cov cheeb tsam tsis muaj lub zog. Txawm li cas los xij, cov nplaim taws qhib ua rau muaj kev pheej hmoo tua hluav taws, thiab roj cua nab kuab yuav tsum tau ua kom zoo kom tsis txhob muaj cov kua tawg lossis tawg.
Fais vuam yog nyob ntawm lub zog hluav taws xob, txwv nws siv nyob rau thaj chaw deb tsis muaj hluav taws xob (tshwj tsis yog siv hluav taws xob (tshwj tsis yog siv hluav taws xob (tshwj tsis yog siv hluav taws xob). Nws tseem nkag siab txog cov khoom siv ib puag ncig: cua tuaj yeem cuam tshuam cov kev tiv thaiv cov roj hauv Mig lossis Vuam vuam, thiab cov av noo yuav cuam tshuam rau Arc ruaj khov. Txawm li cas los xij, nws muaj kev nyab xeeb nyob hauv qhov chaw (nrog qhov cua ua kom zoo) piv rau roj vuam, raws li nws cov pa roj ntsha tsawg dua los ntawm cov roj sib txuas.
Kev ua tau zoo thiab nqi
Roj vuam yog qeeb qeeb, tshwj xeeb tshaj yog rau cov ntaub ntawv tuab, vim nws cov khoom cua sov qis dua. Qhov no ua rau nws tsis tshua muaj txiaj ntsig rau loj {1} teev ntau lawm tab sis tus nqi -} Siv tau cov haujlwm me. Thawj cov cuab yeej siv tus nqi qis, tab sis cov nuj nqis txuas ntxiv rau roj ntxiv ntxiv rau lub sijhawm dhau los {{acetylene, tshwj xeeb, yog kim.
Hluav taws xob vuam yog sai dua, nrog cov nqi xa tawm ntau dua (tus nqi ntawm weld hlau ntxiv rau ib feeb), ua rau nws zoo tagnrho rau huab hwm coj ntau lawm. Thaum pib kev nqis peev nyob rau hauv lub tshuab vuam siab dua, hluav taws xob vuam feem ntau muaj hluav taws xob qis dua (raws li hluav taws xob tsawg dua li siv roj ntau. Cov neeg siv tau zoo li cov electrodes lossis xaim kuj tseem raug nqi-}}}} ua tau zoo, rau Mig / TIG / TIG) ntxiv qee cov nuj nqis.
Tag
Roj vuam thiab hluav taws xob vuam sib txawv hauv cov lus qhia hauv cov cua kub, khoom siv, thiab cov ntawv thov. Roj vuam, nrog nws cov nplaim taws -} Ua kom muaj cua sov thiab kev hloov chaw taws teeb, thiab qis}. Hluav taws xob vuam, siv hluav taws xob vuam, muab hluav taws xob los ntawm hluav taws xob, muab cov khoom siv nrawm dua, thiab cov khoom siv vuam, thiab siab} lub zog hlau koom.
Qhov kev xaiv ntawm lawv nyob ntawm qhov zoo li cov ntaub ntawv tuab, nkag mus rau lub zog, xav tau kev yuam kev, thiab ntau lawm volum. Thaum cov roj av vuam tseem muaj txiaj ntsig rau cov haujlwm tshwj xeeb, hluav taws xob vuam cov txiaj ntsig thiab kev yoog raws li cov ntawv thov vuam feem ntau.
