Yog lawm, 5083 txhuas tuaj yeem welded, thiab qhov no yog ib qho kev coj ua vim nws txoj kev vuam zoo heev, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov xws li nkoj tsim thiab cryogenics. Tus yuam sij rau kev ua tiav vuam yog xaiv cov hlau muab tub lim kom raug, xws li 5356, 5183, lossis 5556.
Welding Considerations:
Filler Hlau Xaiv:
5356: Muab cov yas zoo thiab cov xim sib xws tom qab anodizing.
5183: Tshwj xeeb tsim rau 5083, nws muab lub zog zoo heev thiab corrosion kuj, ua rau nws zoo tagnrho rau nkoj hulls.
5556: Muab cov khoom siv kho tshuab me ntsis siab dua thiab tsim nyog rau cov ntawv thov kom muaj zog dua.
Cov txheej txheem vuam:
Gas Tungsten Arc Vuam (GTAW/TIG): Txoj kev no ua kom zoo, siab -cov pob qij txha muaj zog nrog rau qhov nqaim cua sov- thaj tsam cuam tshuam.
Gas Hlau Arc Vuam (GMAW/MIG): Thaum qhov no kuj yog ib txoj hauv kev, nws yuav ua rau muaj porosity ntau dua yog tias tsis ua tib zoo.
Joint zog:
5083 txhuas tuav lub zog sib koom ua ke tom qab vuam thiab tsis tshua muaj kev sib tsoo piv rau lwm cov alloys, xws li 6061. Nws tuav nws lub zog zoo dua tom qab- vuam, thaum alloys zoo li 6061 muaj kev poob qis hauv lub zog.
Cov teeb meem muaj peev xwm:
Softening: Vuam tuaj yeem ua rau qee qhov muag muag hauv tshav kub- cuam tshuam cheeb tsam. Txawm li cas los xij, cov nyhuv no tuaj yeem txo qis los ntawm kev siv cov khoom siv hlau kom raug thiab cov txheej txheem vuam, xws li TIG vuam.
GNEE, tus thawj coj hauv Suav teb, muab siab - zoo 5083 aluminium alloys, muab cov khoom siv zoo tshaj plaws rau ntau yam kev siv hauv kev lag luam xws li nkoj tsim, cryogenics, thiab ntau dua.
Teeb meem hla Kev Qhia Kho Khoov Ntawm 5083 Base Alloy
Cov lus qhia kom dhau qhov Kev Ntsuas Khoov ntawm 5083 Base Alloy
Ntau tus kws tsim khoom lag luam ntsib teeb meem thaum sim ua kom dhau qhov kev ntsuas khoov ntawm 5083 cov ntaub ntawv hauv paus. Kab lus no yuav pab koj nkag siab tias yog vim li cas cov kev ntsuam xyuas yuav ua tsis tau thiab yuav tsum tau siv cov filler alloys.
Dab tsi yog Qhov Kev Ntsuam Xyuas Kev Ncaj Ncees?
Kev ntsuas khoov taw qhia yog kev tswj xyuas zoo siv los ntsuas qhov ductility ntawm cov hlau vuam ntawm ob lub ntsej muag thiab cov hauv paus hniav ntawm kev sib koom ua ke. Thaum lub sij hawm xeem, tus qauv yog khoov 180 degree. Lub ntsej muag khoov yog ua nrog lub ntsej muag weld nyob rau hauv nro, thaum lub hauv paus khoov xeem yog ua nrog lub weld cag hauv nro.
Vuam 5083 Base Material
5083 txhuas tuaj yeem ua tiav siv 5356, 5183, thiab / lossis 5556 muab tub lim. Txhua yam ntawm cov muab tub lim no yog tsim rau vuam 5083, tab sis kev xaiv ntawm cov muab tub lim yog nyob ntawm daim ntawv thov tshwj xeeb thiab cov kev pabcuam ntawm cov khoom siv welded.
5083 cov khoom siv hauv paus yog siv nyob rau hauv ntau yam kev lag luam, suav nrog kev tsim cov nkoj, cov tso tsheb hlau luam cryogenic, tsheb tub rog, thiab cov khoom tsim. Nyob rau hauv cov nqe lus ntawm kev tsim, rau fillet welds, tus raug transverse shear zog ntawm cov muab tub lim yog 26 Ksi rau 5356, 28 Ksi rau 5183, thiab 30 Ksi rau 5556, feem.
Xaiv txoj cai Filler Alloy
Thaum xav txog groove weld transverse tensile lub zog, 5356 muab tub lim yog feem ntau siv rau ntawm 5083 cov khoom siv hauv paus tsuas yog thaum tsis muaj qhov yuav tsum tau ua rau cov txheej txheem vuam txheej txheem tsim nyog. Txawm li cas los xij, 5356 yuav tsis ua raws li qhov yuav tsum tau muaj lub zog tensile (40 Ksi lossis 275 MPa) rau groove welds ntawm 5083 cov khoom siv hauv paus.
5183 muab tub lim, tshwj xeeb tshaj yog tsim rau 5083, ua tau raws li cov khoom siv cuab yeej cuab tam rau cov txheej txheem vuam txheej txheem tsim nyog . 5556 muaj cov khoom siv tshuab me ntsis siab dua 5183 thiab tuaj yeem siv rau vuam qhov siab dua - lub zog 5456 cov khoom siv hauv paus. Nws kuj ua tau raws li qhov xav tau ntawm tensile yam tsawg kawg nkaus rau 5083.
Nws yog ib qho tseem ceeb tsis txhob siv 4043 los yog 4047 muab tub lim alloys thaum vuam 5083 cov khoom siv, vim cov no tsis haum rau 5xxx series cov ntaub ntawv hauv paus nrog ntau dua 2.5% magnesium.
Vim li cas Cov Kev Ntsuas Kev Ntsuas Khov Tsis Tau?
Muaj ntau qhov laj thawj vim li cas qhov kev ntsuas khoov taw qhia yuav ua tsis tiav:
Discontinuities hauv Weld:Feem ntau qhov ua rau tsis ua haujlwm yog qhov tsis sib xws hauv cov vuam, xws li tsis muaj fusion, uas ua rau tawg. Cov qauv ua tsis tiav yuav tsum raug tshuaj xyuas los txiav txim siab tias qhov kev tsis sib haum xeeb ua rau qhov ua tsis tiav.
Cov txheej txheem xeem tsis raug:Tej zaum qhov kev xeem yuav tsis raug ua kom raug. Piv txwv li, cov qauv kuaj yuav tsis tau npaj kom raug, lossis lub vojvoog dabtsi yog khoov tuaj yeem tsis raug. Nws yog ib qho tseem ceeb rau kev ntsuam xyuas cov qauv ua tsis tau zoo kom paub tseeb tias nws tau npaj raws li cov qauv tsim nyog, thiab cov txheej txheem xeem yuav tsum tau kuaj xyuas kom raug.
Txoj Kev Xeem:Lub wraparound coj khoov txoj kev xeem yog cov txheej txheem kev ntsuam xyuas zoo tshaj plaws rau aluminium weldments vim qhov hloov pauv tseem ceeb hauv cov khoom siv kho tshuab ntawm qee cov aluminium alloys. Txoj kev sim plunger tsis pom zoo rau siab dua -lub zog aluminium alloys zoo li cov kev sim no.
Tsis tsim nyog Filler Alloy:Siv cov khoom siv tsis zoo, xws li 4xxx series muab tub lim rau ntawm 5xxx lub hauv paus khoom, tuaj yeem ua rau lub vuam tsis zoo, ua rau nws tsis ua haujlwm ntau dua.
GNEE, tus neeg muag khoom hauv Suav teb ntseeg siab, muaj cov khoom zoo - zoo 5083 cov ntaub ntawv zoo thiab cov khoom siv sib xyaw ua ke, kom ntseeg tau cov welds txhim khu kev qha uas ua tau raws li cov qauv tsim nyog.
