Thaum nws los txog rau Tig Vuam Stainless Hlau, kev xaiv cov pa roj uas cuam tshuam ncaj qha weld zoo, thiab arc stability. Argon, ib qho roj inert, tsis yog tsuas yog siv tau kev xaiv rau txoj haujlwm no - nws yog cov qauv kev lag luam rau Tig vuam stainless hlau. Nws cov khoom tshwj xeeb ua rau nws muaj kuab haum los tiv thaiv lub pas dej weld, khaws cia cov khoom siv corrosion, thiab ua kom muaj kev siv vuam ruaj khov.
Argon's inert qhov yog nws qhov tseem ceeb tshaj plaws. Tsis zoo li cov pa roj oxygen (xws li oxygen lossis nitrogen), nws tsis hnov mob nrog molten stainless hlau, lub tungsten electrode, lossis cov khoom siv hauv cov khoom. Stainless hlau tso siab rau chromium (18 {{{}}}}}}}}}}) cov qib sib tw oxide uas tiv thaiv corrosion. Thaum raug rau qhov kub thiab txias thaum lub sij hawm vuam, cov txheej no tuaj yeem tawg, thiab chromium dhau los ua rau oxidation yog tias tsis muaj kev tiv thaiv. Argon cov ntaub ntawv ntom ntom, tiv thaiv thaj tsam vuam, cais cov pas dej molten thiab cua sov}) los ntawm atmospherion oxygen thiab nitrogen. Qhov no tiv thaiv chromium los ntawm kev sib txuas nrog oxygen los ua cov chromium oxides-tebchaw-teb uas deplete cov hlau ib corrosion tsis kam. Yog tsis muaj kev tiv thaiv no, WELD thiab thaj chaw ib puag ncig yuav raug rau xeb, pitting, thiab kev ua tsis tiav, txawm tias muaj ib puag ncig me me.
Ntxiv nrog rau corrosion tiv thaiv, Argon txhawb nqa ib qho ruaj khov Arc -}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Koj puas xav tau meej tswj tau cov lus tawm sov. Tig vuam siv ib qho tsis- Consumable tungsten elcsten elcsten elcsten elc, thiab cov khoom ionization pab tswj cov ANCOLDY ARC. Qhov kev ruaj khov no ua kom muaj zog ua kom muaj zog ntawm cov hlau hauv paus thiab cov xaim xaim (yog siv), ua rau nws tswj tau cov pas dej Molten. Rau cov hlau stainless, uas muaj tsawg thermal conductivity thiab siab thermal nthuav dav, cov cua sov tsis sib xws tuaj yeem ua rau warping, distortion, lossis tsis sib xws. Lub arc uas sib xws los ntawm arcon txo cov kev pheej hmoo no, pub muaj hwj huam los tsim cov txiv ntoo huv si, hnav khaub ncaws me me lossis tsis raug cai.
Argon tau sib txuam nrog txhua qhov kev ua haujlwm ntawm cov hlau uas tsis muaj zog (suav nrog 304, 316, thiab lawv cov khoom siv tsis tau) thiab ua haujlwm zoo nkauj Hauv cov ntawv thov autrogenous - Xws li koom nrog tus weld retains, zam kev tsis muaj peev xwm ua kom muaj zog. Thaum siv cov hlau ntim (piv txwv li, er308L rau 304 stainless ua kom muaj zog me me nrog lub hauv paus hlau, tiv thaiv porosity lossis suav nrog lub zog.
Thaum ntshiab argon yog tus qauv, ntxiv rau lwm cov roj av yuav siv tau hauv cov xwm txheej tshwj xeeb. Piv txwv li, ntxiv 1 {-}}} Txawm li cas los xij, hydrogen yuav tsum tau siv kev ceev faj: ntau ntau tuaj yeem ua rau muaj feem ntau hauv cov hlau uas tsis muaj ntsej muag lossis embrittlement nyob rau qee cov alloys. Helium yog lwm yam kev ntxiv, feem ntau siv los ua kom sov tawm hauv siab, tab sis nws yuav tsum kim dua li cov neeg sib cav ntshiab rau feem ntau cov ntawv thov. Rau feem ntau ntawm cov tswv yim vuam -}} ntawm cov khoom noj khoom haus stainless hlau-ntshiab tau muab cov txiaj ntsig zoo sib xws.
Kev tsim kom tsim nyog tiv thaiv roj yog qhov tseem ceeb rau maximizing argon cov hauj lwm zoo. Cov pa yuav tsum tau ntws los ntawm tus nqi txaus (feem ntau 10 {{{{}} nee 20 cubic feet ib teev, tab sis tsis yog li nrawm nrawm, uas tuaj yeem kos tau hauv cov kab mob tsis huv. Ib qho kev ntsuas roj no (qhov loj me rau cov khoom tuab) ua kom cov pam vov) ua kom lub cev sib txawv npog chav weld, Tungsten electrode, thiab Haz. Yuav tsum muaj cov tshuaj welders yuav tsum ua kom cov pa roj yog pub dawb lossis tsis muaj zog me me ntawm cov pa dej tuaj yeem ua rau muaj feem hws nyob hauv Weld.
Hauv cov ntsiab lus, Argon tsis yog tsuas yog tsim nyog rau Tig cov hlau Stainless {}} nws yog cov kev tiv thaiv roj uas nyiam. Nws cov inert kev tiv thaiv khaws cia tsis muaj roj stainless hlau corrosionance los ntawm kev tiv thaiv chromium oxidation, thaum nws arc- Stabilizing cov khoom siv ua kom meej meej meej, tswj kev vuam. Seb ua haujlwm nrog nyias - cov ntaub ntawv txuas, lossis siv cov xaim hlau, ntshiab argon muab cov txiaj ntsig zoo ib yam, siab- Cov txiaj ntsig zoo. Rau feem ntau stainless hlau Tig daim ntawv thov vuam, Argon tseem muaj kev cia siab, muaj kev cia siab, thiab kev ua tau zoo kom tau raws li kev lag luam thiab kev siv hluav taws xob vuam.
