Yog lawm, koj tuaj yeem vuam 5083 txhuas nrog 5356 muab tub lim, tab sis nws tsis yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau lub zog tensile siab. Filler alloys zoo li 5183 lossis 5556 feem ntau pom zoo kom ua tau raws li cov cai. Thaum 5356 yog qhov tsim nyog rau kev siv dav dav - lub hom phiaj vuam thiab muab cov hlua txuas ntxiv nrog lub zog ntau dua li 4043 muab tub lim, nws yuav tsis ua raws li 40 ksi tensile lub zog xav tau los ntawm qee cov lej rau 5083 welds.
Yog vim li cas 5356 Tej zaum yuav yog ib qho teeb meem
Lub zog txwv:5356 muab tub lim tsis tas yuav ua tiav 40 ksi yam tsawg kawg nkaus tensile lub zog xav tau los ntawm cov lej rau 5083 cov khoom siv hauv paus, feem ntau ua rau muaj zog tensile qhov tseem ceeb xws li 37-39 ksi.
Code Requirements:Cov lej zoo li AWS D1.2 pom zoo kom siv 5183 lossis 5556 muab tub lim rau vuam 5083 kom ntseeg tau tias 40 ksi tensile zog yuav tsum tau ua.
Thaum siv 5356
Kev siv dav dav:Rau ntau qhov dav dav - lub hom phiaj welds, qhov twg 40 ksi tensile lub zog yuav tsum tsis yog qhov tseem ceeb, 5356 tuaj yeem yog qhov kev xaiv tsim nyog vim nws lub zog thiab zoo corrosion kuj.
Fillet Welds:Nws yog ib qho kev xaiv muaj zog rau fillet welds, feem ntau siv rau hauv cov ntawv thov uas lub zog tseem ceeb tshaj qhov ua tau raws li cov kev xav tau tshwj xeeb tensile.
Ductility:5356 muab ductility zoo dua li 5183, ua rau nws yog ib qho kev xaiv zoo rau cov ntawv thov uas xav tau kev hloov pauv.
Lwm txoj kev
5183:Tsim tshwj xeeb rau vuam 5083 txhuas, nws ntseeg tau raws li cov cuab yeej cuab tam rau cov cai - tsim nyog welds.
5556:Qhov muab tub lim no muaj cov khoom siv kho tshuab me ntsis siab dua 5183 thiab tseem yuav ua tau raws li qhov yuav tsum tau muaj zog tensile yam tsawg kawg nkaus rau 5083 cov khoom siv.
GNEE, tus thawj coj hauv Suav teb, muab siab -cov ntaub ntawv zoo 5083 thiab cov khoom siv sib xyaw ua ke, kom ntseeg tau tias koj cov welds ua tau raws li cov qauv tsim nyog rau ntau yam kev siv.
Q:Kuv tabtom ua cov txheej txheem kev tsim nyog ntawm 5083-0 temper khoom siv 5356 muab tub lim hlau thiab roj hlau arc vuam (GMAW). Txawm li cas los xij, kuv cov qauv tensile ib txwm ua tsis tiav, nrog lub zog tensile tshwm sim los ntawm 37 txog 39 KSI, thaum txoj cai yuav tsum muaj lub zog tensile yam tsawg kawg nkaus ntawm 40 KSI. Kuv ua txhaum dabtsi? Kuv puas yuav tsum tau txo cov cua sov tawm?
A:Tsis yog, txo cov cua sov tawm yuav tsis cuam tshuam rau lub zog tensile ntawm tsis yog - tshav kub- kho tau txhuas alloys zoo li 5083. Qhov teeb meem koj tab tom ntsib yog ib qho tshwm sim heev -koj siv cov hlau tsis raug.
Tau ntau xyoo, 5356 tau suav tias yog "universal" muab tub lim rau 5xxx series alloys, thiab nws feem ntau ua haujlwm zoo. Nyob rau xyoo 1980, cov vuam siv feem ntau siv 5356 rau vuam 5083. Txawm li cas los xij, ob peb xyoos dhau los, cov lej tau pib xav tau lub zog tensile yam tsawg kawg nkaus ntawm 40 KSI rau 5083 welds. Nws tau pom sai sai tias kev ua tiav 40 KSI nrog 5356 muab tub lim yog qhov nyuaj heev. Thaum qee zaus koj tuaj yeem ncav cuag 40 KSI, ntau zaus, lub zog tensile poob ntawm 37 txog 39 KSI, raws li koj tau ntsib. Yog vim li cas yog tias 5356 tsis muaj cov ntsiab lus alloying txaus kom ua tiav qhov xav tau 40 KSI.
Txhawm rau ua tau raws li 40 KSI qhov yuav tsum tau ua, 5183 thiab 5556 muab tub lim tau tsim. Ob leeg ntawm cov muab tub lim no muaj cov ntsiab lus alloying ntau dua li 5356 thiab ua tau raws li 40 KSI tensile zog yuav tsum tau. Ntawm ob, 5183 feem ntau siv. Qhov tseeb, yog tias koj sab laj AWS D1.2 (Structural Welding Code-Aluminum), Table 4.2, koj yuav pom tias 5183 thiab 5556 yog cov khoom siv hlau pom zoo rau vuam 5083, tsis yog 5356.
Kuv ntseeg siab tias yog tias koj hloov mus rau 5183 muab tub lim, koj cov txheej txheem tsim nyog yuav raug daws.
GNEE, tus neeg muag khoom suav nrog ntseeg siab, muajsiab - zoo 5083 puag phaj cov ntaub ntawv, xyuas kom meej tias koj cov txheej txheem vuam ua tau raws li cov qauv kev lag luam thiab dhau qhov kev xeem tsim nyog.
