| Nws yog xim hlau inert roj vuam | Siab arc zog, ceev vuam ceev | Siv rau vuam tuab qhov chaw, tuaj yeem weld thickness hauv qab 50 hli |
| Nws yog xim hlau inert gup mem tes vuam | ME ME WARD WARDE ARMRATIONS, zoo tsis kam mus pores thiab tawg, ntau txoj kev ntsuas kev hloov kho | Siv rau nyias daim hlau los yog tag nrho cov-ua haujlwm vuam, feem ntau yog siv rau kev ua haujlwm nrog lub thickness ntawm 2 txog 12 hli |
| Ntshav arc vuam | Hnov tshav kub kub, nrawm vuam ceev, me vuam deformation thiab kev ntxhov siab, cov txheej txheem nyuaj | Siv rau hauv qab vuam vuam qhov twg qhov yuav tsum tau ua siab tshaj Argon arc vuam |
| Nqus Plua Plab Av Thaiv Vuam | Siab rau qhov tob, thaj me me kub-cuam tshuam cheeb tsam, me vuam deformation, zoo sib luag cov cuab yeej siv | Siv rau vuam me me weldments |
| Laser Vuam | Me vuam deformation, kev tsim khoom siab | Siv rau weldments uas yuav tsum muaj kev rov ua haujlwm vuam |
(1) Roj vuam oxygen-acetylene roj vuam muaj tsawg heev yog qhov tsis muaj roj av, tab sis kuj tseem ceeb rau kev tsis xws luag xws li txhuas oxide suav, Pores thiab tawg . Txoj kev no tsuas yog siv rau kev siv cov txheej txheem tsis zoo ntawm 0 {}}} 5 txog 10 hli.
(2) tungsten inert roj vuam no yog welded nyob rau hauv kev lag luam {2} Nws yog qhov sib zog ua kom tiav yog ib qho ntau dua vuam txoj kev rau aluminium alloys, tab sis tus tungsten inert roj vuam cov cuab yeej muaj ntau dua thiab tsis haum rau kev ua haujlwm sab nraum zoov nyob rau hauv qhib cov huab cua mob {}}
(3) Hlau Arcon Vuam Tsis Siv Neeg Hlau ArcStion, thiab tuaj yeem muab cov cua sov Alloy phaj nrog ib tuab ntawm 30 mm . Cov khoom siv tsis zoo los tau siv rau kev muab cov khoom sib cav sib ceg vuam, tab sis txoj kab uas hla ntawm ib txwm yog thev vuam yog thanner thiab Weld muaj ntau dua Porosity Concetitivity.
(4) mem tes argon arc vuam
1) tungsten electrode mem tes arc vuam {} Txoj kev tswj hwm vuam thiab yooj yim} Tus txheej txheem cua sov tam sim no tau txhim kho thiab siv hluav taws xob ntau dua Aluminium, Super-nyuaj Aluminium, thiab lwm yam.
2) pulsed Argon arc vuam . Qhov hluav taws xob ntau, cov khoom lag luam kub yog qhov zoo, thiab cov khoom sib tsoo kub tau zoo mm .
(5) Kuj tseem ceeb chaw welding thiab leeg vuam yuav tsum tau siv rau cov khoom lag luam uas muaj ntau dua li 4 hli ntxiv, thiab cov khoom lag luam ntau dua. nws yog tshwj xeeb rau huab hwm coj-tsim thiab cov khoom siv .
(6) Kev sib txhuam do vuam kev sib txhuam ua kom muaj vuam hlau thiab thaiv kom muaj kev sib tw welding, nws tsis yog txwv rau cov kab sib txuas thiab cov khoom siv hlau thiab tuaj yeem thaiv cov kab thiab muaj peev xwm weld Txoj kev ncaj qha. Txoj kev vuam no tseem muaj kev sib koom ua ke, tsis muaj kuab paug, puas muaj kuab lom
Vuam cov ntaub ntawv rau txhuas
(1) VUAM HLAU NYOB RAU VUAM KHWV TAU SIV GASTENS VUAM KHAU YAM, THIAB ALTOUS}, Muab Tawv Vuam Hlau Welded tivthaiv yuav tsum tau txiav txim siab thiab lub vuam hlau tsim nyog rau cov khoom siv niam txiv yuav tsum raug xaiv los ua cov tub lim khoom {{4 4}}
Thaum xaiv cov hlau vuam, thawj qhov uas yuav tsum tau txiav txim siab ntawm cov khoom lag luam ntawm cov niam txiv, cov xim tsis zoo, cov xim tsis yeem ntawm cov khoom siv hluav taws xob hauv kev sib tsoo hauv cov pa taws kub, lub zog ntawm Lub weld sib koom ua ke nce nyob rau hauv kev txiav txim ntawm 1000 series, 4000 series, thiab 5000 series.
5000 series vuam cov xov hlau uas muaj ntau dua 3% yuav tsum tau zam rau cov neeg siv hluav taws xob ntau dua li ntawm cov hluav taws xob nrog cov hluav taws xob ntau dua li ntawm cov hluav taws xob sib tsoo ntawm weld hlau {}}
Tam sim no, feem ntau ntawm cov vuam hlau rau txhuas cov xov hlau yog HS311, uas muaj cov qauv vuam sib xyaw ua ke, me me los ntawm cov qauv vuam hlau, me me los ntawm cov khoom siv vuam sib xyaw ua ke Kuj . Nyob rau hauv thiaj li yuav kho cov nplais nplej thiab cov khoom siv hluav taws xob tsis kam xws li ti, thiab zr feem ntau ntxiv rau cov xov tooj ua hloov kho.
Hauv qab no yog cov teeb meem uas yuav tsum tau them sai sai thaum xaiv txhuas alloy vuam hlau:
1) Cov khoom siv sib tsoo weld {1} Txoj kev sib tw ntawm cov niam txiv uas muaj kev cuam tshuam nrog cov khoom siv weld thiab kub thiab txias. 0 {{. 6%, tib alloy tau raug xaiv los ua Weld, thiab cov tawg nrawm yog qhov loj heev.
Txawm li cas los xij, ER4043 vuam hlau nrog cov ntsiab lus silicon ntawm 561 aliet, vim Al-MG-CU muaj qhov siab nrawm nrawm.
2) Cov khoom siv neeg kho tshuab ntawm welded pob qij txha {}} muaj cov hlau tsis muaj zog, yog li txhuas cov hlau loj tshaj plaws tom qab vuam, sile hlau yuav tsum tau zam .
3) Kev ua yeeb yam ntawm welded pob qij. Qhov kev xaiv ntawm kev sib koom ua ke, thiab cov khoom siv hluav taws xob tsis zoo rau kev ua haujlwm, thiab cov khoom siv welded kev tawm tsam lossis tiv thaiv kev sib kis los ntawm cov khoom ntim cia {{} Lub cev tub rog yuav tsum muaj tsawg kawg ntawm niam txiv hlau.
