Cov lus teb yog qhov tseeb yog. Argon tsis yog tsuas yog siv hluav taws xob ntxiv rau lub vuam vuam stainless hlau tab sis kuj yog ib qho kev xaiv feem ntau hauv daim ntawv thov no. Nws cov khoom tshwj xeeb ua kom nws zoo- haum kom tau raws li cov kev xav tau ntawm Tigent Stainless Hlau, kom muaj kev siab dua {{}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} zoo welds.
Argon ua raws li kev thaiv cov roj thaiv hauv TIG VUAM, thiab lub luag haujlwm no tseem ceeb heev thaum vuam stainless hlau. Thaum lub sij hawm vuam txheej txheem, lub arc hluav taws xob yog tsim tawm ntawm lub tungsten electrode thiab lub stainless hlau ua haujlwm ua haujlwm, uas melts lub hauv paus hlau thiab ib tus tub lim hlau siv. Thaum muaj kub kub, molten stainless hlau yog muaj kev cuam tshuam zoo heev los reacting nrog cov khoom hauv huab cua, xws li cov pa thiab cov pa taws. Cov kev tawm tsam no tuaj yeem ua rau muaj teeb meem ntawm cov teeb meem: oxidation tuaj yeem ua rau kev tsim ntawm brittle oxides hauv weld, txo nws txoj kev tawm tsam thiab corrosion tsis kam; Nitrogen kev nqus tuaj yeem ua rau weld hlau nyuaj thiab nkig, nce kev pheej hmoo ntawm kev tawg. Argon, ua cov pa roj inert, tsis muaj kev cuam tshuam nrog cov hlau molten. Nws tsim qhov thaiv kev tiv thaiv ib puag ncig lub pas dej weld, cais nws los ntawm cov huab cua nyob ib puag ncig thiab tiv thaiv cov kev phom sij uas muaj kev phom sij. Qhov no ua kom pom tseeb tias lub weld khaws cov khoom uas ntxim nyiam ntawm cov hlau stainless, xws li corrosion tsis kam.
Siv Argon li cov kev tiv thaiv roj rau Tig vuam Stainless hlau muaj ntau yam zoo. Nws muab cov arc zoo heev. Lub arc ruaj khov yog qhov tseem ceeb rau kev ua tiav weld nkag thiab hlaws, uas yog qhov txawv txav ntawm welds tuaj yeem ua rau nws ua tau zoo. Argon tseem tso cai rau kev ua kom zoo ntub ntawm Molten hlau, lub ntsiab lus Weld Weld pas dej kis tau tusyees thiab ntseeg tau, ua rau muaj kev zoo nkauj weld hlaws. Qhov no tau txais txiaj ntsig zoo rau ob qho tib si cov tsos thiab cov qauv kev ncaj ncees ntawm Weld.
Feem ntau, Ntshiab Argon yog txaus rau Tig vuam Stainless Hlau, tshwj xeeb tshaj yog rau nyias rau cov ntawv tuab tuab. Txawm li cas los xij, hauv qee qhov xwm txheej tshwj xeeb, ntxiv rau lwm cov roj av mus rau argon tuaj yeem suav tau los ua kom tau zoo dua cov txheej txheem vuam. Piv txwv li, ntxiv ib qho me me ntawm hydrogen (feem ntau yog 1% {%) rau kev cuam tshuam txog cov qib weld tuaj yeem txhim kho nrog qee cov qib weld uas muaj weld da dej. Tab sis nws yuav tsum tau sau tseg tias hydrogen ntxiv yuav tsum tau ceev faj, raws li ntau yam kev pheej hmoo ntawm hydrogen - muaj zog stainless hlau qib. Lwm qhov kev xaiv yog Argon nrog feem pua me me ntawm helium (nyob ib ncig ntawm 25%- 75}}}}}}}}}}}}}}}}}}}}}}}}}}} helium). Helium nce lub tswv yim cua sov ntawm arc, uas tuaj yeem pab tau rau vuam tuab stainless hlau, raws li nws tso cai rau kev nkag mus tob. However, helium is more expensive than argon, so pure argon remains the cost - effective choice for most standard TIG welding applications of stainless steel.
Muaj qee qhov kev txiav txim siab tseem ceeb thaum siv Argon rau Tig Vuam Stainless hlau. Tus nqi txaus ntawm lub argon tiv thaiv roj yog qhov tseem ceeb. Ib qho dhau - Cov nqi ntws qis tsawg tsis tau muab kev tiv thaiv zoo txaus, pub muaj huab cua rau infiltrate chav weld pas dej. Ib yam dhau {{4 4} high high high high high high high high high high high breath breatkas muaj kev ntxhov siab hauv cov roj cua, kos duab hauv huab cua los ntawm ib puag ncig. Feem ntau, tus nqi txaus ntawm 10 - 20 cubic feet ib teev, tab sis nws tuaj yeem hloov kho raws li feem ntau ntawm cov khoom siv, thiab muaj cov ntawv sau nyob hauv ib puag ncig vuam.
Tsim kom tsim nyog ua kom tsim nyog kuj yog qhov tsim nyog. Cov teeb tsa TIG yuav tsum tau tuav ntawm cov kev ncua deb ntawm kev ua haujlwm ruaj khov ntawm Arc thiab cov kev pab them hluav taws xob uas tsis zoo. Lub kaum sab xis ntawm lub raj tsau tuaj yeem cuam tshuam cov roj ntws thiab chav weld pas dej zoo, yog li cov kev txav tes ua tau zoo rau kev ua tiav cov txiaj ntsig zoo.
Ib qho ntxiv, cov kev coj dawb huv ntawm cov roj av sib cav teeb meem. Siab - Kev Purity Argon (nrog kev coj dawb huv ntawm 99.99% lossis siab dua). Impurities nyob rau hauv lub argon, xws li oxygen lossis noo noo, tuaj yeem paug lub pas weld pas dej, ua kom tsis xws luag lossis oxidation. Siv cov roj txheem roj uas tau txhim khu kev qha thiab ua kom tau zoo cia thiab tuav ntawm lub tog raj kheej argon tuaj yeem pab tswj kev siv roj.
Hauv kev xaus, Tig vuam Stainless hlau nrog Argon tsis yog tsuas yog ua tau tab sis kuj xyaum ua haujlwm thiab ua haujlwm zoo. Argon lub peev xwm los muab cov ntaub thaiv npog tiv thaiv cov cua hauv kev ua paug, nrog rau nws txoj kev koom tes ntawm Weld Carret tswj, ua rau nws xaiv zoo. Los ntawm kev them nyiaj rau cov yam ntxwv xws li roj av tswj hwm, lub teeb puro {{2} {} {{} {} {} {} {} {} {} {ristant welds thaum tig welding welding welding stainless hlau nrog argon.
