Thaum fabricating nrog5086 aluminium yeeb nkab, tshwj xeeb tshaj yog rau cov ntawv thov tseem ceeb hauv marine lossis offshore, kev xaiv ntawm vuam hlau tsis yog qhov nthuav dav me. Nws yog qhov kev txiav txim siab tseem ceeb uas cuam tshuam ncaj qha rau kev ncaj ncees, kev nyab xeeb, thiab ntev - lub sij hawm corrosion tsis kam ntawm tag nrho koj qhov project.
Kev siv cov hlau tsis zoo yog qhov tseem ceeb tsis txaus tos kom tshwm sim. Nws tuaj yeem ua rau tsis muaj zog, tawg- cov pob qij txha yooj yim, cuam tshuam kev tiv thaiv corrosion hauv dej hiav txwv, thiab thaum kawg, kev sib txuas uas ua tsis tau raws li kev nruj DNV lossis ABS cov qauv hauv zej zog.
Nyob rau hauv phau ntawv qhia kev paub no, peb yuav piav qhia qhov zoo tshaj plaws vuam hlau rau 5086 txhuas, sib piv ob qhov kev lag luam -txoj kev xaiv-ER5356 thiab ER5183-thiab muab tswv yim tswv yim los xyuas kom meej tias txhua qhov weld koj tsim muaj zog, ruaj, thiab ua raws li tag nrho.
1. Qhov zoo tshaj plaws vuam hlau rau 5086 Aluminium
Rau vuam engineers thiab fabricators uas xav tau ib tug ceev, txhim khu kev qha cov lus teb, lub rooj no summarizes qhov raug muab tub lim xaiv hlau.
| Vuam Hlau | Thawj Alloying Element | Raws li -Welded Strength | Seawater Corrosion Resistance | Zoo tagnrho Siv Case rau 5086 Txhuas |
| TIAB SA 5356 | ~ 5% Magnesium (Mg) | Siab | Zoo heev | Kev lag luam-tus qauv ua haujlwm rau kev tsim khoom hauv hiav txwv dav dav, cov kav dej ua ke, thiab siab - kev siv kev ntxhov siab. |
| TIAB SA 5183 | ~4.7% Mg + Manganese (Mn) | Siab heev | Superior | Qhov kev xaiv zoo tshaj plaws rau hnyav -cov dej hiav txwv dej hiav txwv, siab - cov tshuab siab, thiab thaum yuav tsum muaj qhov siab tshaj plaws weld zog. |

2. Yog vim li cas koj yuav tsum tsis txhob siv Pure Aluminium Vuam Hlau rau 5086
Ua ntej peb tham txog cov kev xaiv uas yog, nws yog ib qho tseem ceeb kom nkag siab txog yam tsis siv. Ib qho yuam kev ua los ntawm cov neeg tsim khoom siv tsis tau paub yog sim vuam 5086 txhuas nrog cov ntshiab txhuas muab tub lim hlau zoo li ER1100.
Qhov no yuav ua rau muaj kev phom sij tsis muaj zog.
Qhov laj thawj yog qhov yooj yim metallurgy. 5086 txhuas yog lub siab- zog txhuas-magnesium alloy, muaj 3.5% rau 4.5% magnesium. Qhov no alloying ntsiab yog dab tsi muab nws lub zog thiab zoo heev marine corrosion kuj. Txhawm rau tsim kom muaj zog vuam, cov hlau muab tub lim yuav tsum muaj cov tshuaj lom neeg sib xyaw ua ke thiab sib tw (lossis me ntsis overmatches) lub hauv paus hlau cov khoom.
Siv cov mos, ntshiab txhuas hlau zoo li ER1100 qhia txog qhov tsis muaj zog txuas. Lub resulting weld yuav muaj:
- Tsawg Tensile Strength: Cov hlaws hlaws yuav tsis muaj zog dua li qhov nyob ib puag ncig 5086 yeeb nkab, ua rau nws tsis ua haujlwm.
- Tsis zoo Corrosion Resistance: Qhov sib txawv ntawm cov tshuaj pleev ib ce ntawm cov weld thiab cov yeeb nkab tuaj yeem tsim cov galvanic cell hauv dej hiav txwv, ua rau cov vuam corrode sai heev.
Rau txhua yam qauv lossis siab- daim ntawv thov khaws cia, siv cov khoom siv zoo aluminium-magnesium vuam hlau yog qhov yuav tsum tau ua.
3. ER5356 vs ER5183: Qhov Vuam Hlau Qhov Zoo Tshaj Plaws rau 5086 Txhuas?
Kev xaiv kom raug ntawm cov hlau muab tub lim rau 5086 txhuas ib txwm nqes mus rau ob txoj kev xaiv los ntawm 5xxx series: ER5356 thiab ER5183. Ob qho tib si yog cov kev xaiv zoo heev, tab sis lawv tau tsim kho rau qib sib txawv me ntsis ntawm kev ua tau zoo.
TIAB SA 5356
ER5356 vuam hlau yog feem ntau siv muab tub lim hlau rau vuam 5086 txhuas. Nrog kwv yees li 5% magnesium, nws muab cov kev sib txuas nrog kev sib tsoo zoo heev, lub zog tensile siab, thiab zoo heev corrosion kuj nyob rau hauv dej ntsev.
- Magnesium ntsiab lus: ~ 5.0%
- Hom Tensile Strength (Raws li -Welded): ~ 276 MPa (40 ksi)
- Xaiv ER5356 thaum: Koj tab tom tsim cov qauv hauv hiav txwv dav dav, nkoj nkoj cov kav dej, cov hlab ntsha siab, thiab txhua daim ntawv thov uas yuav tsum muaj lub zog thiab kev ntseeg siab. Nws yog ntau yam thiab tus nqi - kev xaiv zoo rau ntau dua 90% ntawm 5086 txoj haujlwm vuam.
TIAB SA 5183
ER5183 vuam hlau yog ntau dua - ua tau zoo muab tub lim hlau tsim rau cov kev thov tshaj plaws. Thaum nws cov ntsiab lus magnesium qis me ntsis (nyob ib ncig ntawm 4.7%), nws muaj ntau dua manganese thiab chromium. Qhov no chemistry ua rau muaj kev sib tsoo nrog lub zog tensile thiab ductility.
- Magnesium Cov ntsiab lus: ~ 4.7% (+ siab dua Mn & Cr)
- Hom Tensile Strength (Raws li -Welded): ~ 296 MPa (43 ksi)
- Xaiv ER5183 thaum: Koj qhov project muaj qhov hnyav -lub luag haujlwm lossis cov khoom tseem ceeb. Hauv peb qhov kev paub dhau los, vuam engineers rau offshore platforms, tub rog nkoj, thiab cryogenic LNG piping systems feem ntau qhia ER5183 vs. ER5183 vuam hlau kom ua tiav qhov ua tau zoo tshaj plaws kev sib koom ua haujlwm thiab kev nyab xeeb.
4. Kev coj ua zoo tshaj plaws rau Vuam 5086 Aluminium Yeeb Nkab
Xaiv txoj hlua hlau yog kauj ruam ib. Cov txheej txheem tsim nyog yog qhov tseem ceeb los xyuas kom meej qhov siab - vuam zoo.
- Kev tu kom huv si tsis yog-Tshaj tawm: Ua ntej koj tawm tsam ib qho arc, 5086 yeeb nkab nto thiab thaj chaw sib koom yuav tsum huv si zoo kawg nkaus. Siv ib qho tshwj xeeb stainless hlau xaim txhuam (tsis txhob siv ib qho ntawm cov hlau) kom tshem tawm cov txheej oxide saum npoo. Tom qab ntawd, so thaj chaw nrog cov kuab tshuaj zoo li acetone kom tshem tawm cov roj lossis roj.
- Siv 100% Argon Shielding Gas: Rau MIG (GMAW) thiab TIG (GTAW) vuam ntawm txhuas, ntshiab Argon yog tus qauv shielding roj. Nws muab qhov ruaj khov arc thiab tiv thaiv kev sib kis atmospheric.
- Siv cov txheej txheem "Push": Thaum MIG vuam, ib txwm siv lub kaum sab xis ( taw tes rau rab phom mus rau kev taw qhia). Qhov no muab kev tu kom zoo dua qub thiab ua kom cov pa roj zoo.
- Tswj Koj Cov Cuab Yeej Cuab Yeej: Txhuas ua kom sov sai heev. Siv qhov nrawm nrawm nrawm thiab tsis txhob nyob hauv ib qho chaw. Cov cua kub ntau dhau tuaj yeem ua rau cov cua sov tsis muaj zog- thaj chaw cuam tshuam (HAZ) thiab ua rau muaj kev cuam tshuam ntau ntxiv. Rau 6 hli (1/4 ") tuab 5086 yeeb nkab, qhov pib ntawm MIG vuam yuav nyob ib ncig ntawm 180-200 amps.
