Vuam yog ib qho kev xav tau hauv ntau lub lag luam.Fusing thiab manipulating hlau rau hauv cov duab thiab cov khoom yuav tsum tau cov kws tshaj lij uas tau kawm lawv cov khoom siv tes ua los ntawm cov tub ntxhais kawm mus rau tus tswv los ntawm qhov pib.Kev saib xyuas kom meej ua rau tus welder zoo, thiab vuam zoo heev muaj nuj nqis hauv ntau lub khw muag khoom.Raws li kev siv hluav taws xob txuas ntxiv mus rau dej nyab kev lag luam, vuam tseem yog ib qho txuj ci uas tsis tuaj yeem ua tiav cov neeg hlau, thiab cov kws txawj welds yeej ib txwm xav tau.
Vuam / Arc Vuam (SMAW)
Stick welding tseem hu ua shielded hlau arc vuam (SMAW).Nyob rau hauv no txoj kev ntawm vuam, tus welder siv ib tug vuam pas nrig nyob rau hauv ib tug phau ntawv txheej txheem, siv ib tug hluav taws xob tam sim no los tsim ib tug arc ntawm tus pas nrig thiab cov hlau yuav tsum tau koom.Txoj kev no feem ntau yog siv rau hauv kev tsim kho cov qauv steel thiab hauv kev lag luam fabrication rau vuam steel.Ib tug welder uas siv txoj kev no yuav tsum tau txawj txaus kom dhau lub vuam hlau los ntawm kev puas tsuaj khoov kev sim.Txoj kev no yooj yim heev rau kev kawm, tab sis yuav tsum muaj kev kawm ntev ntev los ua tus tswv.Cov welding tseem tsis tsim qhov zoo nkauj tshaj plaws, yog li nws yog qhov zoo tshaj plaws rau cov welds uas tsis pom hauv cov khoom tiav.Txoj kev no yog qhov zoo rau kev kho cov khoom siv vim nws ua haujlwm ntawm xeb, pleev xim rau thiab qias neeg.
Hlau inert gas (MIG) vuam los yog GMAW
Gas Hlau Arc Vuam (GMAW) tseem hu ua MIG (Metal Inert Gas) vuam.Txoj kev vuam no siv cov roj thaiv kev tiv thaiv raws li cov electrodes thiab tom qab ntawd ua kom sov ob lub hlau sib txuas.Txoj kev no yuav tsum muaj qhov hluav taws xob tas li los ntawm DC lub zog hluav taws xob thiab yog cov txheej txheem vuam siv ntau tshaj plaws.Txoj kev no yog qhov zoo rau welding tuab daim hlau rau hauv txoj hauj lwm kab rov tav.
Tungsten Inert Gas (TIG) Vuam (GTAW)
Gas tungsten shielded welding (GTAW), tseem hu ua TIG (tungsten inert gas) vuam, feem ntau yog siv los txuas ua ke tuab ntu ntawm cov hlau tsis muaj hlau lossis cov hlau tsis muaj hlau.Qhov no yog lwm cov txheej txheem arc vuam uas welds nrog ib qho khoom siv tungsten electrode, tab sis cov txheej txheem siv sij hawm ntau dua li cov nplaum los yog MIG vuam.Qhov sib xyaw ntawm lub hauv paus hlau yog qhov tseem ceeb heev thaum siv txoj kev no, vim tias feem pua ntawm chromium cuam tshuam rau qhov kub thiab txias.Hom kev vuam no tuaj yeem ua tiav yam tsis muaj cov hlau muab tub lim.Vim tias cov roj ntws tas li yuav tsum tau ua, txoj kev no yog qhov ua tau zoo tshaj plaws nyob rau hauv lub chamber deb ntawm cov khoom.TIG welding tsim cov welds zoo nkauj, tab sis nyuaj rau tus tswv thiab yuav tsum tau muaj kev paub thiab txawj welder.
Flux cored arc vuam
Flux cored arc vuam (FCAW) tau tsim los ua lwm txoj hauv kev tiv thaiv vuam.Txoj kev no yog ceev thiab nqa tau yooj yim, thiab yog txoj kev siv ntau tshaj plaws hauv kev tsim kho.Nws yog siv nyob rau hauv ib tug ntau yam ntawm vuam tej yaam num thiab muaj zoo saj zawg zog nyob rau hauv lub kaum sab xis, voltage, polarity thiab ceev.Hom vuam no yog qhov zoo tshaj plaws ua rau sab nraud lossis hauv qab lub fume hood vim nws tsim ntau cov pa taws thaum ua haujlwm.
Txawm hais tias hom vuam siv rau koj cov kev cai hlau fabrication project, nws yog ib qho tseem ceeb kom muaj ib tug kws welder uas to taub qhov intricacies ntawm txhua txoj kev thiab cov hlau lawv ua hauj lwm nrog.Ib lub khw muag khoom zoo tshaj plaws steel fabrication yuav muaj ib pab neeg muaj zog ntawm cov welders uas txaus siab rau lawv cov khoom siv tes ua thiab tuaj yeem pom zoo rau hom vuam zoo tshaj plaws rau txhua qhov haujlwm.
