Nyob rau hauv tus txheej txheem ntawm lo vuam vuam, ntsug vuam yog ib qho kev ua haujlwm welders yog: thaum ua kev kub ntxhov vuam, nws puas zoo dua los xaiv ntsug los yog ntsug? Qhov teeb meem no tsis yog tsuas yog muaj feem cuam tshuam nrog qhov nyuaj ntawm kev ua haujlwm tab sis kuj cuam tshuam rau qhov zoo ntawm Weld, yog li ua lub ntsiab lus tseem ceeb hauv kev ua haujlwm vuam thiab kev sib pauv.
Ntsug pas vuam, raws li txoj kev vuam vuam, raws li kev vuam txoj kev uas muaj kev siv tshuaj dawb, muaj qhov muaj peev xwm tswj tau cov welders piv nrog lub ntsej muag vuam. Cov hlau molten nyob rau hauv cov txheej txheem vuam cuam tshuam yog cuam tshuam los ntawm kev sib tsoo, uas yog qhov yooj yim ntws mus rau hauv qab, yog li kev xaiv ntawm vuam kev taw qhia tshwj xeeb.
Ntsug cia cov vuam vuam txhais tau tias kev lag luam vuam yog nqa tawm los ntawm sab saum toj mus rau hauv qab raws cov kev taw qhia ntsug ntawm cov weldment. Txoj kev vuam vuam no muaj qhov zoo ntawm kev siv vuam ceev. Txij li cov hlau molten ntws mus hauv qab nrog kev txiav txim siab nyob rau hauv qhov kev sib tsoo, uas haum rau cov xwm txheej uas yuav tsum tau ua haujlwm. Ib qho ntxiv, txoj kev ntsug vuam yog qhov yooj yim rau kev ua haujlwm, thiab rau qee qhov kev pheej hmoo nyias, nws tuaj yeem txo qhov kev pheej hmoo ntawm hlawv {}} los ntawm rau qee yam. Txawm li cas los xij, txoj kev ntsug mus vuam kuj muaj cov kev txwv pom tseeb. Vim tias cov kav hlau sai ntawm cov hlau molten, nws yog qhov nyuaj rau tsim qhov chaw nyob fusion txaus, thiab weld feem ntau ntiav. This makes it only applicable to non-critical structural parts or thin-plate welding with low strength requirements, such as some decorative parts or temporary connection components. Ntxiv mus, yog tias txoj kev ua haujlwm tsis raug, tsis raug xws li undercut thiab tsis tiav fusion yog yooj yim tshwm sim.
Ntsug Up Steel Vuam yog qhov fab ntxeev. Lub lag luam welding pib txij hauv qab thiab txav mus siab nce raws txoj kev xav ntawm weldment. Txoj kev vuam vuam no tuaj yeem kov yeej kev cuam tshuam ntawm kev sib tsoo ntawm cov hlau. Thaum lub sij hawm vuam ua haujlwm, cov ntaub thaiv hluav taws yuav tswj tau zoo melting molting hlau, ua rau cov weld muaj qhov tob loj dua thiab muaj cov khoom siv zoo dua. Yog li ntawd, ntsug vuam yog dav siv nyob rau hauv cov qauv tseem ceeb uas xav tau lub zog tseem ceeb thiab nruj me me, thiab cov tshuab ua haujlwm zoo, thiab cov tshuab ua haujlwm hnyav, thiab cov tshuab ua haujlwm hnyav, thiab cov tshuab ua haujlwm hnyav, thiab cov tshuab ua haujlwm hnyav, thiab cov tshuab ua haujlwm hnyav. Ib qho ntxiv, Ntsug ntau hom vuam yog ntau dua rau cov roj thiab slag hauv lub pas dej molten, txo qhov tshwm sim ntawm pores thiab slag inclusion tsis zoo. Txawm li cas los xij, ntsug vuam muaj qhov yuav tsum muaj rau cov neeg muag khoom. Nws yuav tsum tau muab pov ntawv rau tswv tus tswv qhov tsim nyog vuam ceev thiab electrode lub. Yog tias qhov nrawm nrawm dhau, nws yog qhov yooj yim los ua kom muaj kev tsis muaj zog; Yog tias qhov nrawm qeeb dhau, nws yuav ua rau ntau dhau kev sib txuam ntawm cov hlau thiab kev ua haujlwm tsis zoo. Nyob rau tib lub sijhawm, lub vuam ceev ntawm ntsug los ntawm vuam yog qhov qeeb, uas yuav txo cov haujlwm ua haujlwm rau qee yam.
Kev lag luam insiders tau hais tias kev xaiv ntawm ntsug thiab ntsug hauv lo vuam nyob ntawm ntau yam. Ua ntej, nws yog ib qho tsim nyog los xav txog qhov yuav tsum tau ua ntawm weldment. Yog tias nws yog qhov tseem ceeb tivthaiv nrog lub zog siab thiab ua tau zoo, ntsug vuam yog undoubtedly thawj qhov kev xaiv; Yog tias nws yog ib qho tsis - tseem ceeb nyias-}}}}}}}} peel ib feem uas ua rau muaj kev ua haujlwm tau zoo, ntsug hauv vuam yuav suav tau. Thib ob, cov tuab ntawm lub workpiece tseem yog qhov tseem ceeb tshaj plaws. Tuab workpieces feem ntau xav tau txaus fusion tob, yog li ntsug vuam yog qhov haum ntau; Nyias workpieces tuaj yeem siv ntsug ntsug vuam kom tsis txhob hlawv - los ntawm. Ib qho ntxiv, qib kev txawj ntse ntawm cov kws kho vaj tsev yuav tsum tau coj mus rau hauv tus account. Ntsug cov vuam vuam yuav tsum tau ua haujlwm ntau dua. Yog tias tus tswv cuab cov thev naus laus zis tsis paub txaus, nws yuav nyuaj rau kev ua tiav cov kev xav tau vuam.
Coob tus welders uas paub ntau tau muaj cov kev paub ua tau zoo nyob rau hauv ntev -} kev ua haujlwm. Piv txwv li, thaum ua tau cov ntaub ntawv vuam ntsug, lawv yuav tsum tau kho cov hlau thiab kho kom yooj yim los pab txhawb kev ntws ntawm Molten hlau thiab kev tiv thaiv ntawm arc. Thaum siv txoj kev ntsug vuam, lawv yuav nce vuam ceev kom tiv thaiv ntau dhau kev sib txuam ntawm Molten hlau thiab xyuas kom meej qhov kev sib sau ntawm Weld.
Nyob rau hauv dav dav, muaj tsis muaj meej "zoo dua" ntawm ntsug thiab ntsug hauv pas vuam. Lawv muaj lawv tus kheej cov xwm txheej uas siv tau thiab cov yam ntxwv kev ua haujlwm. Welders yuav tsum muaj kev nkag siab ntau yam xws li cov khoom siv weldment, cov kev xav tau ntawm Weld, thiab lawv txoj kev ua haujlwm los ua qhov kev xaiv tsim nyog. Nrog kev txhim kho tshuab txuas ntxiv mus ntawm vuam technology thiab cov kev txuam nrog ntawm Welder kev paub, daim ntawv thov cov kev sib tw ntau ntxiv thiab muaj txiaj ntsig zoo, muab cov haujlwm lav tau zoo rau qhov zoo ntawm ntau hom vuam.
