1.Mig Vuam (hlau inert-roj vuam)
MIG VUAM (HLAU INTER-roj VUAM) ntiav cov neeg muaj kev pab cuam. Qhov no arc vuam txoj kev siv cov roj sab sab sab sab sab sab sab sab sab sab sab sab sab sab sab sab sab sab sab sab sab sab sab sab sab sab sab nraud raws li cov tee hluav taws xob hlau los tiv thaiv cov pa hlau, thiab kub kub weld firs. Thaum siv cov roj ntsha
Mig vuam sib txuas lus sib xws nrog tus welding vuam tshwj tsis yog rau hloov lub tungsten electrode nrog nws yog xim hlau hlau. Cov xaim yog melted los ntawm arc thiab ua tsis tu ncua pub rau hauv weld cheeb tsam. Muaj hluav taws xob cov neeg yob cia li pub rau cov hlau los ntawm cov zaub ntoo rau qhov chaw ua haujlwm. Thaum siv DC arc raws li lub qhov kub kub, nws polarity yog rov qab rau ntawd ntawm Tig vuam. Cov kev thaiv cov roj muaj ntau yam sib txawv txawv thiab feem ntau ntxiv 1% oxygen mus argon los txhim kho arc stability.
Zoo ib yam li Tig Vuam, Mig tuaj yeem tiv thaiv txhua tus hlau, tshwj xeeb qhia tau zoo tshaj qhov ua tau zoo nrog aluminium alloys, tooj liab / tooj liab alloys, thiab stainless hlau. Cov txheej txheem nthuav tawm minimal oxidative poob nrog tsuas yog evaporation, uas ua rau qhov yooj yim mellurgical cov txheej txheem.
2.Tig vuam (tungsten inert roj vuam)
Kuj tseem paub tias yog roj tungsten arc vuam (gtaw), tig vuam sawv cev rau kev sib tw ntawm {}}}}} Cov hlau-Fed Teig cov txheej txheem tshwj xeeb yog txaus nyiam rau hauv paus hla rau hauv siab lub nkoj nyob rau hauv siab lub nkoj vuam zoo li nws cov roj av tshwj xeeb uas tsis muaj kuab.
3.Technical tsis muaj:
Thaum tshav kub kub: DC ARC (10-95 v Ua Haujlwm Voltage, txog 600a Tam Sim No)
Polarity: workpiece txuas nrog lub davhlau ya nyob twg, tungsten electrode raws li kev tsis zoo
Kev thaiv cov roj: feem ntau yog sib cav, qee zaum nrog 5% hydrogen ntxiv rau kev nce tshav sov (txwv tsis pub muaj ferritic steel)
Roj Flow Tus Nqi: {3-8 l / min
Kev tiv thaiv backside: Cov kev thaiv cov roj ntxiv uas yuav pom zoo rau Weld Underside
Cov Khoom Siv Ua Si: Txuas Ntxiv Austenitic Qib (piv txwv li, Hom 316 rau Ferritic Stainless Hlau)
4.Adavages:
Cov kua roj hauv cov roj ntawm cov ntaub thaiv hluav taws xob cais tawm cov hlau los ntawm cov hlau los ntawm cov pa hluav taws xob hauv atmosphricer, ua rau qe vuam zoo tagnrho rau:
Oxidation-prone tsis-ferrous hlau (al, mg alloys)
Stainless hlau & Kev Kub Kub Kub Alloys
Titanium / Titanium alloys
Refractory refactive cov hlau (mo, NB, ZR)
5.While muaj feem rau cov pa roj carbon thiab cov neeg siv hluav taws xob tsawg, cov nqi ntawm cov nqi tseem ceeb thiab cov nqi tso tseg rau cov nqi thiab qis qis dua piv rau cov hau kev uas pom zoo.
