VUAM VUAM 304 Stainless Hlau Tshais Yuav Tsum Hlau Uas Ua Rau Nws Qhov Txawv Alloy Composition {}}}}}}}}}}}}}}}}}}}}}}}}}}}} Qhov "txoj cai" hlau nyob ntawm cov txheej txheem vuam (tshee, cor, thiab txhua yam yuav tsum tau ua qhov tshwj xeeb nrog 304's Chemistry. Ntawm no yog kev tawg ntawm cov xov hlau zoo tshaj plaws rau txhua tus txheej txheem, kom paub meej Welds uas tau ntsib 304 tus qauv kev kawm.
Tig Vuam: ER308L rau precision thiab corrosion tsis kam
Tig (tungsten inert roj) vuam, teeb meem rau kev kho kom huv, kom zoo nkauj, tso siab rau ntawm ib tug sib cais hlau los koom 304 stainless hlau. ER308L yog qhov kev lag luam qauv rau cov txheej txheem no. Nws muaj pes tsawg leeg -}}}}}}}}}}}} {{{{{{, cov chromium evaporation hauv arc). Tus "l" txhais tau cov pa roj carbon (tsawg dua los yog sib npaug rau cov chromium reacts nrog carbides-resistant chromium nyob rau hauv lub tshav kub-cuam tshuam cheeb tsam (hz).
ER308L's Molten Flothity kom nws yooj yim tswj rau nyias {}} Cov khoom siv kho mob, lossis cov cuab yeej kho mob, lossis kos duab kho mob. Nws khub uas tau sib ceg nrog cov kev tiv thaiv sib ceg Rau thicker 304 ntu (3-6mm), er308l tswj cov laj kab tsis sib xws uas tsis muaj kev phom sij ntau, txo kev phom sij ntev, txo kev phom sij ntev, txo qis kev phom sij.
Ib qho tshwj xeeb variant, er308lsi, yog qhov zoo rau cov neeg tsis huv lossis cov xwm txheej yuav tsum tau zoo dua Arc ruaj khov. Cov khoom seem ntxiv txhim kho Molten pas dej ntws, txo cov khoom siv tsis zoo xws li undercutting, thaum khaws cov roj carbon kom tsis txhob muaj cov rhiab. Qhov no ua rau nws muaj txiaj ntsig zoo rau siab - heev vol ntau lawm qhov twg beatiable yog qhov tseem ceeb.
MIG VUAM: ER308L rau kev ceev thiab versatility
MIG (hlau inert roj) Vuam siv cov hlau txuas ntxiv uas ua raws li ob lub electrode thiab muab ceev, ua rau nrawm dua li tig rau loj- nplai 304 cov haujlwm. Ntawm no, Er308L yog dua qhov kev xaiv zoo tshaj plaws. Nws cov chemistry kom muaj weld hlau sib tw 304 tus corrosion tsis kam, thaum nws cov tshuaj lom neeg du dag zog rau kev tswj hwm 304 6} {tiv taus tiav.
Mig vuam 304 nrog ER308L yuav tsum tau tiv thaiv roj (feem ntau 98%}}}}}}}}}}) los tiv thaiv cov pas dej Molten. Cov hlau cov ntsiab lus tsawg cov ntsiab lus ua haujlwm nrog cov roj no sib xyaw los tsim cov khoom siv ruaj khov thiab cov khoom tso tawm}}} Cov tsheb tso tsheb hlau luam 304 tso tsheb hlau luam lossis cov kev txhawb nqa. Rau thicker 304 ntu (ntau dua los yog sib npaug rau 4mm), er308l tus nqi yuav tsum tau txo qis tsawg kawg nkaus uas xav tau, txuag lub sijhawm yam tsis muaj kev txi zoo.
Flux -} cored vuam: e308LT1-1 rau kev siv sab nraum zoov lossis kev siv
Flux -} Cored Vuam tshem tawm cov roj av, ua rau nws muaj kev tiv thaiv sab nraud lossis chaw taws teeb (piv txwv li cov chaw tsim kho nrog cua). Rau cov txheej txheem no, E308LT1-1 yog cov hlau pom zoo. Nws muab kev pab cuam tshuam nrog cov txiaj ntsig zoo nrog cov ris tsho tiv thaiv flux
Qhov "LT1 {{- 1" qhia tias nws yog qhov ntsuas roj av, haum rau ntsug lossis siv nyiaj ntau dua 304. Nws cov flux ua ib qho slag uas tau ua tau sai sai, txhawb nqa cov pas dej Molten hauv tsis} txoj haujlwm tiaj tus thiab tiv thaiv drips. Thaum flux {{[{8}} cored hlau yuav tsum tau tom qab Weld Tshem Tawm, E308LT1-1 nplooj tsawg kawg nkaus li residue, yooj yim tu. Nws yog qhov zoo tagnrho rau 304 daim ntawv thov uas muaj peev xwm Portability ntau dua li tsis meej precision, xws li cov tsheb ciav hlau sab nraum zoov lossis cov khoom siv sab nraum zoov.
Cov xov hlau tshwj xeeb rau Niche 304 daim ntaub ntawv
Hauv cov xwm txheej tshwj xeeb, lwm cov xov hlau txhim kho kev ua tau zoo:
ER316L: rau 304 welded nyob rau hauv ib puag ncig corrosive heev (xws li cov nroj tsuag ntug dej hiav txwv lossis tshuaj lom neeg), Er316L Ntxiv rau 2-3% Molybdenum kom tiv thaiv pitting thiab crevice corrosion. Thaum tsis tsim nyog rau tus qauv 304 siv, nws muab kev tiv thaiv ntxiv uas sillwater, acids, lossis cov av noo yog cov kev txhawj xeeb.
ER309L: Thaum Vuam 304 rau cov hlau roj (ER309L cov ntsiab lus tsiv teb tsaws chaw), er7% ni) tiv thaiv cov pa roj teeb, zam brittle martensite tsim nyob rau hauv lub Haz.
Qhov tseem ceeb hauv kev xaiv xaim
Xaiv cov hlau yog rau 304 stainless hlau khawm rau:
Corrosion xav tau: ua ntej ER308L (lossis Er316L rau cov chaw huab cua zoo) kom tau txais 304 tus xeb tsis kam.
Cov txheej txheem sib xyaw: phim cov hlau rau cov txheej txheem - E} ET308L rau Tig / Mig, E308 {} 1 rau flux-cored.
Cov Khoom Thickness: ER308L ua haujlwm rau feem ntau 304 thicknesses, thaum er308LSI AIDS ntws hauv ntu thicker.
Ib puag ncig: flux - cored e308LT1-1 suits sab nraum zoov siv; ER308L nrog kev thaiv cov roj yog qhov zoo dua rau cov khw muag khoom.
