Vuam SS 304 {{- Qhov siv dav hlau uas phim rau cov khoom siv hluav taws xob kom pom cov khoom tseem ceeb xws li xeb thiab tshuab zog. Cov electrode yuav tsum kuj ua kom muaj kev tsis txaus ntseeg hauv tsev kawm ntawv, kev tsis xws luag, thiab kev sib xyaw nrog cov txheej txheem vuam. Tom qab kev ua lag luam dav ntxiv, E308L-16 tau tawm los ua cov elevero uas tsim nyog tshaj plaws rau vuam SS 304, nrog cov variants tshwj xeeb muaj rau cov ntawv thov tshwj xeeb.
SS 304 lub tub ntxhais lub zog nyob hauv nws cov lus sib xyaw ua ke: 18 -}}}}}}}}}}}}}. Txhawm rau tswj cov khoom no hauv Weld, lub electrode yuav tsum tau replicate no cov kev pheej hmoo, depleting corrosion-resistant chromium nyob rau hauv lub tshav kub-cuam tshuam cheeb tsam (Hz). E308L-16 tau tsim los daws qhov no: nws muaj 19-21% chromium thiab 9-11% cuaj caum (tsawg dua los yog sib npaug ntawm "l") los tiv thaiv cov rhiab. Qhov no ua kom pom tseeb ntawm Weld khaws SS 304 lub peev xwm los tawm tsam oxidation, txawm tias muaj cov khoom siv noo noo xws li cov khoom siv hauv chav ua noj lossis tsev ua noj.
Tus "16" hauv e308l - 16 qhia nws yog txiv qaub {}} pitania coated electrode tsim rau AC lossis DC Rov qab polarity (DCP) vuam. Cov txheej no ua si lub luag haujlwm tseem ceeb hauv SS 304 vuam: Nws tsim cov pa hluav taws xob ib ncig ntawm cov pas dej molenen, tiv thaiv kev paug tawm ntawm cov pa roj oxygen. Yog tsis muaj daim hlau thaiv, SS 304 yuav nqus roj, ua kom porosity lossis oxide suav uas tsis muaj zog ntawm kev sib koom ua ke. Cov txheej ntxiv tseem ua rau cov nplais uas ua tau sai sai, txhawb nqa pas dej Molten rau txhua txoj haujlwm (tiaj, kab rov tav, siv nyiaj ua haujlwm) weld ntxuav. Cov versatility no ua rau e308L-16 haum rau muaj ntau yam SS 304 cov haujlwm, los ntawm me fabriccications rau cov qauv loj.
E308l {{4 4}} 16 qhov kev ua tau zoo txuas ntxiv rau ob qho tib si nyias thiab tuab SS 304 ntu. Rau nyias - kev siv cov khoom siv " Rau cov tuab tuab (4-10 hli), nws muaj kev nkag siab zoo heev, ua kom muaj kev lom zem tag nrho ntawm cov khaubncaws sab nraud pov thawj tsis muaj ntau dhau lawm. Qhov no sib xws yog qhov tseem ceeb rau SS 304, uas muaj tsawg thermal conductivity tuaj yeem ua rau warping, tab sis e308l-16 lub ruaj khov kev phom sij no.
Hauv cov xwm txheej tshwj xeeb, cov variants ntawm E308L-16 txhim kho kev ua tau zoo:
E308lsi {4 {{4 4}} 16: Ntxiv site rau txhim kho Arc ruaj khov thiab molten hauv cov pob qij txha lossis cov pob qij txha ua pob zeb uas tau pob qij txha muaj qhov nyuaj. Silicon kuj txo qis kev pheej hmoo ntawm undercutting, ib qho teeb meem uas ib txwm muaj nyob hauv kev siv tsheb lossis qib siab-ceev SS 304 vuam.
E316L-16: Muaj Molybdenum (2-3%) rau kev txhim kho pittings, siv thaum muaj ib puag ncig corrosive (piv txwv li cov nroj tsuag ntug dej hiav txwv lossis tshuaj lom neeg). Thaum tsis tsim nyog rau cov qauv SS 304, nws muab ib txheej txheej ntxiv ntawm kev tiv thaiv kev tiv thaiv sillillwater lossis acidic kis tau.
E308L-16 qhov sib xyaw nrog SS 304 yog txuas ntxiv ntxiv los ntawm nws cov khoom siv hlau weld. Lub txiaj ntsig sib koom ua ke SS 304 lub tensile lub zog (ntau dua lossis sib npaug ntawm 65,000 psi) thiab duction nws tuaj yeem tiv thaiv tib yam kev ntxhov siab raws li cov hlau sib txuas. Qhov no yog qhov tseem ceeb rau cov qauv SS 304 cov ntawv thov, xws li kev txhawb nqa nkhaus lossis kev lag luam tshuab, qhov twg weld tsis muaj kev phom sij.
Kev siv tau zoo ntawm e308l- 16 tshaj plaws nws qhov ua tau zoo. Lub electrode yuav tsum muab cia rau hauv ib puag ncig qhuav (noo noo tuaj yeem ua rau hydrogen {[} welds) thiab ci ntawm 250-300℃f yog tias raug cov av noo. SS 304 yuav tsum tau muab cov roj, oxides, lossis xim pleev xim ua ntej vuam-paug tuaj yeem ua rau muaj cov txheej txheem hluav taws xob, ua kom haum. Siv DC thim rov qab polarity (DCR) ua kom zoo rau Arc stability, tab sis ac ua haujlwm rau cov ntawv thov tseem ceeb tsawg.
Thaum lwm cov hluav taws xob (piv txwv li, e309l - 16} {}} Cov ntsiab lus cheman, thiab txhua yam tshuaj lom neeg rau kev khaws cia SS 304 txoj kev tiv thaiv corrosion thiab lub zog. Txawm hais tias siv hauv phau ntawv lossis semi-automated vuam, nws tsis tu ncua ua rau cov khoom zoo SS 304 welds uas sib ntsib cov qauv kev lag luam rau kev ua tau zoo thiab kav ntev.
Hauv cov ntsiab lus, e308l - 16 yog qhov tsim nyog electrode rau vuam SS 304 khoom. Nws cov qauv alloy, cov qauv siv carbon qis, thiab kev tiv thaiv card, thaum nws cov versatility thiab ntseeg tau ua kom nws muaj kev haum rau txhua tus SS 304. Rau welders nrhiav zoo ib yam, corrosion-resistant cov txiaj ntsig nrog SS 304, e308L-16 yog qhov kev xaiv muaj pov thawj.
