MIG welding siv hlau xaim tsis siv tungsten electrode hauv vuam teeb.Lwm tus yog tib yam li TIG vuam.Yog li ntawd, lub vuam hlau yog melted los ntawm arc thiab xa mus rau qhov chaw vuam.Lub tshuab hluav taws xob tsav cov menyuam xa cov vuam hlau los ntawm cov spool mus rau vuam teeb raws li qhov xav tau ntawm vuam.

Lub tshav kub kuj tseem yog DC arc, tab sis qhov polarity tsuas yog qhov txawv ntawm qhov siv hauv TIG vuam.Cov khoom siv shielding gas kuj txawv.1% oxygen yuav tsum tau ntxiv rau argon los txhim kho kev ruaj ntseg ntawm arc.

Kuj tseem muaj qee qhov sib txawv hauv cov txheej txheem yooj yim, xws li kev hloov dav hlau, lub dav hlau pulsating, hloov pauv hloov pauv thiab hloov pauv luv luv.

Pulse MIG vuam kho lub suab

Pulse MIG welding yog MIG vuam txoj kev uas siv mem tes tam sim no los hloov cov pulsating DC ib txwm.

Vim yog siv cov mem tes tam sim no, lub arc ntawm mem tes MIG vuam yog hom mem tes.Piv nrog rau ib txwm tsis tu ncua tam sim no (pulsating DC) vuam:

1. Kev hloov kho dav dav ntawm vuam tsis;

Yog tias qhov nruab nrab tam sim no tsawg dua qhov tseem ceeb tam sim no I0 ntawm kev hloov pauv hloov, qhov kev hloov pauv tseem tuaj yeem tau txais ntev npaum li qhov pulse ncov tam sim no ntau dua I0.

2. Arc zog tuaj yeem tswj tau yooj yim thiab raug;

Tsis tsuas yog qhov loj ntawm mem tes los yog lub hauv paus tam sim no kho tau, tab sis kuj nws lub sijhawm tuaj yeem hloov kho hauv units ntawm 10-2 s.

3. Zoo heev thaub qab vuam muaj peev xwm ntawm nyias phaj thiab txhua txoj hauj lwm.

Lub pas dej molten melts tsuas yog nyob rau hauv lub sijhawm tam sim no, thiab txias crystallization tuaj yeem tau txais hauv lub sijhawm tam sim no.Piv nrog rau kev txuas txuas ntxiv tam sim no, qhov nruab nrab tam sim no (tshav kub nkag rau qhov vuam) yog me dua ntawm qhov chaw ntawm tib qhov nkag.

MIG vuam txoj cai kho lub suab

Sib txawv ntawm TIG welding, MIG (MAG) vuam siv fusible vuam hlau li electrode thiab cov arc hlawv ntawm cov tsis tu ncua welding hlau thiab cov weldment li tshav kub los yaj lub vuam hlau thiab lub hauv paus hlau.Thaum lub sij hawm vuam txheej txheem, lub shielding roj argon yog txuas mus rau lub vuam cheeb tsam los ntawm vuam phom nozzle los tiv thaiv lub arc, molten pas dej ua ke thiab nws nyob ze puag hlau los ntawm cov teeb meem ntawm cov huab cua puag ncig.Lub nruam melting ntawm vuam hlau yuav tsum raug xa mus rau lub vuam pas dej ua ke nyob rau hauv daim ntawv ntawm tee, thiab cov hlau weld yuav tsum tau tsim tom qab fusion thiab condensation nrog molten puag hlau.

MIG vuam feature kho lub suab

⒈ zoo li TIG vuam, nws tuaj yeem vuam yuav luag txhua cov hlau, tshwj xeeb tshaj yog tsim rau vuam aluminium thiab aluminium alloy, tooj liab thiab tooj liab alloy, stainless hlau thiab lwm yam ntaub ntawv.Yuav luag tsis muaj oxidation thiab hlawv poob hauv cov txheej txheem vuam, tsuas yog me me ntawm evaporation poob, thiab cov txheej txheem metallurgical yog qhov yooj yim.

2. Kev ua haujlwm siab ua haujlwm

3. MIG vuam tuaj yeem yog DC rov qab txuas.Vuam aluminium, magnesium thiab lwm yam hlau muaj cov nyhuv cathode atomization zoo, uas tuaj yeem tshem tawm cov oxide zaj duab xis zoo thiab txhim kho vuam zoo ntawm kev sib koom ua ke.

4. Tungsten electrode tsis siv, thiab tus nqi qis dua li ntawm TIG vuam;Nws tuaj yeem hloov TIG vuam.

5. Thaum MIG welding aluminium thiab aluminium alloy, subjet droplet hloov yuav siv tau los txhim kho qhov zoo ntawm welded pob qij txha.

⒍ Raws li argon yog ib qho roj inert thiab tsis hnov ​​​​mob nrog ib yam khoom, nws yog rhiab heev rau cov roj stain thiab xeb rau ntawm qhov chaw ntawm vuam hlau thiab lub hauv paus hlau, uas yog yooj yim los tsim pores.Vuam hlau thiab workpiece yuav tsum tau ua tib zoo ntxuav ua ntej welding.

3. Droplet hloov hauv MIG vuam

Droplet hloov yog hais txog tag nrho cov txheej txheem nyob rau hauv uas cov hlau molten nyob rau thaum xaus ntawm lub vuam hlau los yog electrode cov ntaub ntawv droplets nyob rau hauv qhov kev txiav txim ntawm arc tshav kub, uas yog sib cais los ntawm qhov kawg ntawm lub vuam hlau thiab xa mus rau lub vuam pas dej ua ke nyob rau hauv qhov kev txiav txim ntawm arc tshav kub. ntau zog.Nws yog ncaj qha ntsig txog kev ruaj ntseg ntawm cov txheej txheem vuam, vuam tsim, txaws loj thiab lwm yam.

3.1 quab yuam cuam tshuam cov xaum xaum

Cov tee dej uas tsim los ntawm cov hlau molten thaum kawg ntawm vuam hlau yog cuam tshuam los ntawm ntau lub zog, thiab cov teebmeem ntawm ntau lub zog ntawm kev hloov pauv ntawm cov tee dej sib txawv.

⒈ lub ntiajteb txawj nqus: nyob rau hauv txoj hauj lwm welding tiaj tus, lub ntiajteb txawj nqus kev taw qhia yog tib yam li cov kev taw qhia ntawm droplet hloov mus rau txhawb txoj kev hloov;Overhead welding txoj hauj lwm, hindering droplet hloov

2. Nto nro: tuav lub zog tseem ceeb ntawm cov tee dej ntawm qhov kawg ntawm lub vuam hlau thaum vuam.Qhov thinner qhov vuam hlau, qhov yooj yim dua qhov hloov pauv hloov.

3. Electromagnetic quab yuam: lub zog tsim los ntawm magnetic teb ntawm tus neeg xyuas pib nws tus kheej yog hu ua electromagnetic force, thiab nws cov axial tivthaiv ib txwm nthuav tawm ntawm ntu me mus rau ntu loj.Nyob rau hauv MIG welding, thaum tam sim no dhau los ntawm vuam hlau droplet electrode chaw, tus ntoo khaub lig seem ntawm tus neeg xyuas pib hloov thiab cov kev taw qhia ntawm lub electromagnetic quab yuam kuj hloov.Nyob rau tib lub sijhawm, qhov ceev tam sim no ntawm qhov chaw yuav ua rau cov hlau evaporate zoo heev thiab tsim cov tshuaj tiv thaiv zoo rau ntawm cov hlau nto ntawm cov tee dej.Cov nyhuv ntawm electromagnetic quab yuam ntawm kev hloov pauv yog nyob ntawm cov duab arc.

4. Plasma ndlwg quab yuam: nyob rau hauv lub contraction ntawm electromagnetic quab yuam, lub hydrostatic siab generated los ntawm arc plasma nyob rau hauv cov kev taw qhia ntawm arc axis yog inversely proportional rau tus ntoo khaub lig-sectional cheeb tsam ntawm arc kem, uas yog, nws maj mam txo los ntawm qhov kawg ntawm vuam. xaim mus rau saum npoo ntawm lub pas dej molten, uas yog ib qho txiaj ntsig zoo los txhawb kev hloov pauv ntawm cov tee dej.

5. Spot siab

3.2 droplet hloov cov yam ntxwv ntawm MIG vuam

Thaum lub sij hawm MIG welding thiab MAG welding, droplet hloov tsuas yog siv luv luv-circuit hloov thiab dav hlau hloov.luv Circuit Court welding yog siv rau nyias phaj high-ceev vuam thiab tag nrho txoj hauj lwm vuam, thiab dav hlau hloov yog siv rau kab rov tav taub qab vuam thiab fillet vuam ntawm nruab nrab thiab tuab daim hlau.

Thaum lub sij hawm MIG vuam, DC thim rov qab kev twb kev txuas yog pib saws.Vim hais tias qhov kev sib txuas rov qab tuaj yeem paub qhov kev hloov dav hlau zoo, thiab qhov zoo ion cuam tshuam rau cov tee dej ntawm qhov kev sib txuas zoo, ua rau muaj qhov chaw loj heev los cuam tshuam qhov kev hloov pauv, kom qhov kev sib txuas zoo yog qhov hloov pauv tsis tu ncua.MIG vuam tsis haum rau alternating tam sim no vim hais tias cov melting ntawm vuam hlau tsis sib npaug ntawm txhua ib nrab voj voog.

Thaum MIG welding aluminium thiab aluminium alloy, vim tias txhuas yog ib qho yooj yim rau oxidize, thiaj li yuav ua kom muaj kev tiv thaiv, qhov ntev ntawm lub sijhawm vuam tsis tuaj yeem ntev dhau.Yog li ntawd, peb tsis tuaj yeem txais yuav hom kev hloov dav hlau nrog cov tam sim no loj thiab ntev arc.Yog tias qhov kev xaiv tam sim no ntau dua qhov tseem ceeb tam sim no thiab qhov ntev arc tswj ntawm kev hloov dav hlau thiab luv luv-circuit hloov, subjet hloov pauv yuav raug tsim.

MIG welding yog dav siv los vuam aluminium thiab aluminium alloy workpieces.[1]
