304 Stainless hlau yog ib qho ntawm cov feem ntau siv cov neeg siv cov hlau tsis muaj zog tshaj, muaj txiaj ntsig zoo rau nws cov txiaj ntsig corrosion zoo heev, kev sib txawv, thiab weldability. Nws muaj 18-20% chromium thiab 8-10.5% npib tsib, uas yog cov khoom siv roj hmab tiv thaiv cov khoom noj, chav ua noj ua zaub mov, thiab tso tawm tshuaj lom neeg, thiab tshuaj lom neeg cov khoom lag luam chim. Txhawm rau tswj cov khoom no hauv welded pob qij txha, xaiv txoj cai vuam pas nrig yog qhov tseem ceeb. E308L-16 VUAM ROD yog cov kev xaiv thoob ntiaj teb rau 304 stainless hlau, nrog nws cov cim muaj pes tsawg leeg thiab kev ua tau zoo ua rau muaj kev xav tau ntawm 304 vuam.
Tus tub laj thawj yog vim li cas e308l - 16 yog qhov haum rau 304 stainless hlau lus dag hauv nws cov lus sib piv ntawm ib qho kev sib xyaw ua ke. Lub pas dej cov khoom tso nyiaj muaj 18-22% chromium thiab 8-11% npib tsib, uas yuav luag zoo ib yam rau cov chromium thiab npib tsib xee ntawm 304 stainless hlau. Qhov no kom ntseeg tau tias tom qab vuam, Weld muaj qhov muaj peev xwm sib xws los ua cov hlau tiv thaiv los ua cov hlau los ntawm dej, huab cua, thiab tshuaj me me. Piv txwv li, thaum vuam 304 stainless dej siv hauv cov dej hauv tsev, siv E308L-16 tuaj yeem ua rau muaj kev sib cuag ntev ntev, tswj xyuas tag nrho cov raj xa dej tsis kam ntawm cov raj xa dej.
Lwm cov ntsiab lus tseem ceeb ntawm e308l {4 4}} 16 yog nws cov ntsiab lus muaj roj carbon monoxent (tsawg dua los yog sib npaug ntawm "l" hauv kev tsim). Cov kab hlau siab hauv vuam muaj peev xwm ua rau muaj teeb meem hu ua "lub zog chromium ntawm cov pa roj hlau tsis muaj zog, txo cov roj ntsha hauv cov cua sov {}}} cuam tshuam cheeb tsam. E308l {{11 {}} 16 minimizes qhov kev pheej hmoo no los ntawm kev cuam tshuam cua sov uas nyob ze ntawm Weld khaws cov roj kub txaus los tswj nws cov roj oxide txaus. Qhov no yog qhov tshwj xeeb tshaj yog li 304 stainless hlau siv rau hauv vaum ib puag ncig lossis huab cua kub hauv cov khoom noj ua haus uas feem ntau ntxuav nrog dej kub.
Hais txog vuam kev kawm, e308l - 16 tseem ua tau zoo tshaj. Nws rutile - Raws cov txheej muab cov txheej txheem ruaj khov, thiab kev tshem tawm slag yooj yim, ua rau nws cov novice thiab kev paub txog welders. Nws ua haujlwm nrog ob qho tib si AC thiab DC cov khoom siv hluav taws xob, muab cov peev txheej ua haujlwm sib txawv hauv qhov chaw ua haujlwm sib txawv {} {{{9 {9} chaw tsim kho. Rau nyias - scehe 304 stainless hlau (tsawg dua 1/4 nti tuab), E308L-16 tus lej pib ua kom muaj kev pheej hmoo ntawm kev kub ntxhov los yog kev ua rog, kom ua kom muaj kev ruaj khov ntawm welded. Rau thicker 304 workpieces, nws tuaj yeem ua tiav qhov kev nkag mus los ntawm kev hloov kho kom haum, kom ua kom tau txais kev nyab xeeb.
Hauv qee qhov xwm txheej tshwj xeeb, lwm txoj kev vuam vuam tuaj yeem suav tias yog kev xaiv, tab sis lawv tsis zoo li e308l- 16. Piv txwv li, E309L-16 yog qhov haum rau vuam 304 stainless hlau rau lwm hom kev siv hluav taws xob (xws li tsis tsim nyog rau vuam 304 mus rau 304, thiab nws yog kim dua. E316L-16, uas muaj molybdenum, muaj zoo corrosion tsis kam nyob rau hauv sillwater lossis 304 vuam tsis muaj qhov "overkill" uas nce cov nqi tsis muaj cov txiaj ntsig zoo.
Txhawm rau ua kom tiav qhov kev ua tau zoo ntawm E308L-16 thaum vuam 304 stainless hlau, qee cov kauj ruam uas tseem ceeb yuav tsum tau ua raws. Ua ntej, kom huv si ntxuav cov nplaim dej 304 lub hauv paus hlau kom tshem tawm cov roj, xeb, lossis oxide txheej, xws li cov paug tsis tuaj yeem ua kom muaj qhov hws hauv Weld. Thib ob, tswj lub vuam tam sim no raws li cov pas nrig taub (piv txwv li, 90-130 amps rau 3.2mm lub pas dej) kom tsis txhob muaj cua sov ntau dhau. Qhov thib peb, tswj kom luv luv arc ntev thaum vuam kom txo qis kev pheej hmoo ntawm cov kev pheej hmoo ntawm atmospheric. Thaum kawg, tom qab vuam, yog tias ua tau, ua ib qho kev kho mob passivation ntawm Weld los kho cov roj chromium oxide txheej, ntxiv txhim kho corrosion.
Hauv cov ntsiab lus, e308l - 16 yog qhov zoo tshaj plaws vuam pas nrig rau 304 stainless hlau. Nws li alloy muaj pes tsawg daim ntawv sib tw 304 lub zog, cov ntsiab lus muaj roj carbon tsawg tiv thaiv cov kev ua tau zoo, thiab cov pob qij txha ua kom zoo. Seb puas muaj cov ntawv thov dav dav lossis xav tau cov ntawv thov, E308L-16 tuaj yeem ntseeg tau tias muaj lub zog, thiab cov tsos ntawm 304 stainless hlau welded qauv, ua rau nws xaiv thawj qhov kev xaiv rau 304 stainless hlau vuam.
