6011 cov pas nrig yog qhov kev xaiv nrov rau kev siv hlau me me thiab tsis muaj peev xwm txiav tawm, xim av, lossis cov xim, lossis roj rau ntawm cov hlau hauv paus. Txawm li cas los xij, thaum nws los rau vuam stainless hlau, cov lus nug tshwm sim: tuaj yeem 6011 pas nrig tau ua tiav? Technically, 6011 cov pas nrig tuaj yeem tsim cov neeg kho tshuab sib txuas ntawm cov hlau stainless, tab sis qhov no tsis txhais tau tias lawv tsim nyog rau txoj haujlwm. Qhov tseem ceeb ntawm 6011 cov pas nrig thiab stainless hlau cov khoom ua rau cov flaws hnyav ua rau weld zoo, thiab ntev} lub sij hawm termability.
Qhov teeb meem tseem ceeb nyob hauv kev sib xyaw ua ke sib xyaw. Stainless hlau tshuav nws corrosion tsis kam rau lub chromium {}} cov me nyuam yaus muaj ntau dua los yog sib npaug ntawm cov hlau muaj ntau dua los yog sib npaug ntawm carbon, manganese, thiab silicon, tab sis yuav luag tsis muaj chromium (feem ntau<0.5%) or nickel. When used to weld stainless steel, the weld pool becomes a mixture of the 6011 rod's metal and the stainless steel base metal. This dilutes the chromium and nickel in the weld to levels far below what's needed to form a protective oxide layer. The result is a weld that acts like a "corrosion magnet"-it will rust, pit, or degrade rapidly in even moderately humid or exposed environments, completely defeating the purpose of using stainless steel.
Lwm qhov teeb meem tseem ceeb yog cov khoom ntiag tug tsis sib haum. Tus Hlau Stainless, tshwj xeeb tshaj yog cov qib qis xws li 304, muaj kev cuam tshuam loj, thiab muaj kev cuam tshuam me me, thiab muaj kev cuam tshuam me me, thiab muaj kev cuam tshuam me me, thiab muaj kev cuam tshuam me me (ib puag ncig me me) 40-50% rau 304 stainless hlau. Qhov no tsim "qhov txuas tsis muaj zog" nyob rau hauv stainless hlau qauv: lub weld tsis tuaj yeem hloov kho lossis deform uas yog lub hauv paus hlau ua, ua rau nws muaj kev ntxhov siab hauv kev ntxhov siab. Piv txwv li, yog 6011 cov pas nrig tau siv rau weld ib lub 304 stack stacket txhawb lub tshuab vibrating, tus weld tuaj yeem tawg tsis pub dhau lub lis piam, cov khoom lag luam tsis ua haujlwm.
Weld zoo kuj tseem pom zoo thaum siv 6011 cov pas nrig ntawm stainless hlau {} rods cia siab rau cov txheej txheem yuam kev me me steel. Thaum lub sijhawm no yog qhov zoo rau cov teeb meem me, nws ua rau muaj teeb meem nrog Arc tsis muaj zog: uas txo qis kev loj hlob (uas txo qis kev loj hlob ntawm cov cua sov {{}}}} cuam tshuam cheeb tsam). Ib qho ntxiv, cov 6011 txheej tsis ua ib daim slag uas thaiv lub pas dej weld los ntawm cov paug ntawm cov khoom siv pa hluav taws (oxygen) thaum txias. Qhov no nce kev pheej hmoo ntawm porosity, suav nrog, lossis oxide nyob rau hauv weld {{} qhov tsis xws luag lub zog thiab corrosion tsis kam.
Txawm nyob hauv ib ntus lossis tsis - tseem ceeb app, 6011 cov pas nrig muaj kev pheej hmoo. Qee tus neeg yuav txiav txim siab siv lawv rau kev kho kom sai ntawm qhov tsis yog {}} Cov kabmob sib tw sib tw) qhov uas pom teeb meem ntau dua li thilters. Txawm li cas los xij, tus weld tseem yuav corrode sai sai, xav tau nquag ua haujlwm. Hauv chaw sab nraum zoov lossis thaj chaw nrog ya raws (piv txwv li, lub 6011 Weld tuaj yeem pib sib koom ua ke thiab tsis muaj kev sib koom ua ke. Rau txhua daim ntawv thov uas weld yuav tsum tau kav ntev dua ob peb lub lis piam, 6011 pas nrig tsis yog cov tshuaj muaj peev xwm siv tau.
Los ntawm kev sib piv, siv lub stainless hlau -}}}}} 346L-16 rau 316), kom muaj 316), kom muaj 316), kom muaj 316), kom muaj 316), kom muaj 316), kom muaj 316), kom muaj 316), ua kom muaj zog ntxiv, thiab cov khoom siv tshuab. Cov pas nrig no tau tsim los tswj cov txheej txheem tseem ceeb chromium thiab cov npib tsib xee uas xav tau rau cov txheej oxide, thiab tsim cov khoom siv kom muaj zog, du ntau cov qauv sib xyaw nrog cov qauv siv stainless hlau.
Hauv kev xaus, thaum 6011 cov pas nrig tuaj yeem tsim kev sib raug zoo ib ntus ntawm cov hlau uas tsis muaj hlau, lawv tsis tuaj yeem ua tau raws li cov cai hlau tsis muaj nqis. Qhov tsis muaj cov chromium thiab npib tsib xee nyob rau 6011 pas nrig dooms weld rau corrosion, thaum mechanical flaws ua rau nws tsis ntseeg tau rau txhua yam thauj khoom lossis kis tau. Rau cov vuam stainless vuam, ib txwm siv qws tsim rau cov qib tshwj xeeb ntawm weld yog muaj zog, ruaj, thiab corrosion {5} {resistant.
