MIG VUAM (HLAU INTER Roj Vuam) yog ua kev zoo siab rau nws txoj kev ua tau zoo thiab hloov kho hauv hlau fabrice, ua rau nws staple rau vuam hlau thiab lwm yam hlau. Txawm li cas los xij, thaum nws los txog txhuas, Mig vuam ntsej muag tseem ceeb heev - ntau heev yog li ntawd ntau cov lus nug siv cov qauv no. Lo lus teb lus dag hauv Aluminium cov ntaub ntawv tshwj xeeb, uas sib tsoo nrog cov qauv hluav taws xob ntawm Mig vuam, tsim teeb tsa cov kev cov nyom uas xav tau cov kev daws teeb meem tshwj xeeb.
Cov hauv paus ua rau: vim li cas thiaj mig vuam tawm tsam nrog txhuas
Aluminium lub cev nqaij daim tawv thiab tshuaj sib ceg ncaj qha cuam tshuam nrog cov txheej txheem mig vuam, los ntawm arc stability rau Weld Kev Ncaj Ncees:
Kev Tsim Tawm Oxide Oxide Txheej Txheem Kev Fusion
Aluminium reacts tam sim ntawd nrog oxygen nyob rau hauv cov huab cua los ua ib tug tuab txhuas oxide (al₂o₃) txheej, txawm tias nyob rau hauv chav tsev kub. Cov oxide no tau muaj suab nrov ntawm kwv yees li 2072℃- deb dua li aluminium tus kheej melting point ntawm 660 degree. Thaum lub sij hawm mig vuam, txheej oxide txheej ua cov teeb meem: nws tsis yaj: nws tsis txhob yaj thaum lub hauv paus ntawm txhuas los ntawm kev ntws thiab fusing kom zoo. Tsis zoo li cov hlau, qhov twg oxides tuaj yeem tawg tau los ntawm arc zog, txhuas oxide yog li tawv tawv ntawd tsis nkag rau nws, ua rau tsis muaj zog, welds peem.
Siab thermal conductivity ua rau kub kub poob thiab distortion
Txhuas ua cua sov txog tsib zaug sai dua li cov hlau. Hauv Mig vuam, lub arc tsim tawm cov cua sov muaj zog, tab sis txhuas sai sai cuam tshuam cov cua sov no rau hauv cov khoom puag ncig. Qhov no ua rau nws nyuaj rau kev tswj hwm lub pas dej ruaj khov-}}}}}}} Xav tau ntau dua cov tshav kub ntau dua li cov vuam hlau dua li cov hlau. Txawm li cas los xij, kev tshav kub ntau dhau mus ntxiv exacerbates lwm qhov teeb meem: Aluminium qis melting point thiab siab thermal nthuav kev coefficiention. Cov cua sov tsis ncaj thiab cua txias thaum mig vuam feem ntau ua rau muaj kev sib tsoo lossis tawg, ua rau cov qauv kev ncaj ncees ntawm cov workpiece ntawm workpiece.
ARC Qhov Tsis Txaus thiab Hlau Teeb Meem
Mig vuam cia siab rau ntawm kev ua kom khov ntawm cov tub lim hlau los tswj kev ua haujlwm arc thiab tso nyiaj rau hauv Weld. Aluminium sau xaim xaim, txawm li cas los xij, yog mos thiab nquag mus kinking, tshwj xeeb tshaj yog nyob rau hauv tus qauv phom phom tsim rau stiffer steel hlau. Qhov kev pub mis tsis xwm yeem cuam tshuam rau Arc, ua rau muaj kev sib tw, tsis sib haum xeeb hlaws tsim, thiab txawm tias arc tas sij hawm. Ib qho ntxiv, txhuas lub hluav taws xob siab cuam tshuam arc tus cwj pwm: lub arc zoo li ua kom pom tseeb ntawm Weld cheeb tsam, txo kev tswj hwm kev faib khoom kub thiab fusion.
Kev kov yeej qhov txawv: Tshwj xeeb mig cov txheej txheem rau txhuas
Thaum mig vuam txhuas yog qhov nyuaj, nws tsis yooj yim sua. Kev nce qib niaj hnub tau tsim cov txheej txheem MIG los daws cov teeb meem no, tig "vim li cas koj tsis tuaj yeem weld aluminium nrog mig?" rau hauv "Yuav ua li cas nws txoj cai":
Cov khoom siv hloov kho rau oxide tshem tawm thiab hlau pub mis
Tshwj xeeb mig phom nrog laub - rub lossis lig sup lossis zaub- rab phom tshuab daws cov teeb meem xov hlau. Push - Rub cov tshuab siv lub cev xaim hluav taws xob kom ua rau cov xaim xaim hluav taws xob nyob ze rau ntawm rab phom taub hau, txo kev sib txhuam thiab kinking. Txhawm rau los ntawm oxide txheej, "pulsed Mig" Teegentical: nws siv siab- zaus} Cov pa tawm tshiab tam sim no, tso cai rau cov tshuaj txhuas kom fuse.
Cov Roj Hluav Taws Xob Hluav Taws Xob Thiab Khoom Siv
Ntshiab Agron yog tus qauv thaiv cov roj rau txhuas mig vuam. Nws lub siab ionization muaj feem cuam tshuam rau arc, thiab nws siv tau kom huab cua tiv thaiv kev tiv thaiv tshiab oxide ua haujlwm hauv vuam. Pre ...- Weld npaj yog qhov tseem ceeb tshaj plaws: roj, thiab cov paug} {} Txhua qhov chaw mos uas muaj peev xwm ntxiab roj av, ua rau porosity.
Cov tswv yim kev tswj hwm kub
Txhawm rau txhawm rau ua kom sov, Mig Welders rau Aluminium siv cov hluav taws xob ntau dua thiab cov khoom ntim hlau khoom noj kom zoo nkauj kom muaj cua sov. Rau cov ntaub ntawv tuab, preheating rau 150-260℃(300-500℃f) qeeb qeeb dissipation, ua kom yooj yim kom muaj lub pas dej molten. Post-weld cooling must also be controlled-avoiding rapid quenching helps reduce residual stress and distortion.
Vim li cas nws tseem ceeb: kev lag luam cuam tshuam ntawm Aluminium MIG VUAM
Aluminium lub teeb yuag, corrosion distance, thiab condosctivity ua nws indispensable nyob rau hauv aerospace, thiab txuas ntxiv kev lag luam. Los ntawm dav hlau thav ntawv rau hluav taws xob tsheb roj teeb, thiab cov vaj huam sib luag hnub ci, txhim khu kev qha cov pob qij txha tseem ceeb heev. Mig vuam, thaum ua kom zoo rau txhuas, muaj kev sib npaug ntawm kev nrawm thiab nrawm dua li cov hau kev qeeb dua li Tigrant.
Cov thawj coj manufacturers tam sim no muab aluminium-}}}}}} ills pulsed mig tshuab uas tau kho kom haum rau Arc ruaj khov. Cov kev hloov tshiab tau nthuav tawm txhuas cov kev siv hauv ntau ntau lawm, qhov twg tus nqi thiab kev tawm tsam yog qhov tseem ceeb. Piv txwv li, cov nroj tsuag tsheb tam sim no siv mig {{welded aluminium cov khoom siv los xyuas kom txo qis ntawm cov txheej txheem tshwj xeeb thiab kev sib xws.
Xaus: Mig Welding Aluminium - nyuaj, tab sis tiav
Lo lus nug "Vim li cas koj tsis tuaj yeem Weld Aluminium nrog MIG?" Cov ntsiab lus tseem ceeb tsis yog qhov khuam hauv Mig Technology, tab sis qhov yuav tsum tau hloov kho nws kom Aluminium cov khoom sib txawv. Thaum tus qauv Mig teeb tsa nrog cov kua oxide, thiab cov khoom siv kub, thiab cov ntaub ntawv tshwj xeeb, txawm tias nyiam, txheej txheem hauv kev tsim khoom niaj hnub.
Raws li kev lag luam thawb lub ntais, ntau cov ntaub ntawv ruaj khov, muaj peev xwm mig weld aluminium tsuas yog cog nyob rau hauv tseem ceeb. Nrog rau kev nce qib tsis tu ncua hauv pulsed zog, roj kev thaiv, thiab cov cuab yeej siv hluav taws xob zoo siab "thiab" tuaj yeem ua pov thawj, txawm tias cov ntaub ntawv piav qhia tseeb tuaj yeem ua tau.
