Vuam, ib qho txheej txheem sib tw hauv kev tsim khoom lag luam thiab kev tsim kev lag luam, tau hloov kho ntau pua xyoo kom tau ua tiav - kev hloov pauv ntawm cov kev siv ntau yam. Nws koom nrog cov ntaub ntawv koom nrog cov ntaub ntawv, feem ntau yog hlau, los ntawm kev thov ntawm tshav kub, siab, feem ntau nrog cov ntaub ntawv sib ntxiv. Tsab ntawv no rho tawm mus rau lwm hom vuam cov tswv yim thiab lawv cov kev siv tshwj xeeb thoob plaws ntau yam haujlwm.
Cov thaiv hlau arc vuam (smaw)
Kuj tseem hu ua lo vuam, smaw yog ib qho ntawm feem ntau dav siv thiab siv tau vuam txoj kev. Nws siv cov khoom siv muaj zog hluav taws xob coated nrog flux. Thaum muaj hluav taws xob cov hluav taws xob tam sim no los ntawm elctrode, nws tsim ib lub arc uas melts ob lub electrode thiab lub hauv paus glux gluiding cov ntaub thaiv roj teeb thiab ib txheej me ntsis nyob hauv pas weld. Qhov kev tiv thaiv me me tiv thaiv cov hlau los tiv thaiv cov hlau molten ntawm kev sib kis los ntawm cov pa taws, ua kom muaj lub suab Weld.
Smig yog ntau ntau yam, muaj peev xwm vuam ntau ntawm cov hlau, suav nrog cov hlau hlau, hlau hlau, thiab nrum hlau. Nws tuaj yeem siv tau rau hauv ntau qhov chaw los hloov cov khw, ua rau nws zoo tagnrho rau sab nraum zoov thiab ntawm - chaw vuam cov haujlwm. Nws yooj yim, kev pom tseeb, thiab tus nqi qis ua rau nws tus nqi nrov rau cov neeg pib tshiab thiab cov tub txawg. Piv txwv li, hauv kev tsim kho ntawm cov raj xa dej hauv thaj chaw deb, smaw yog feem ntau ua haujlwm vim nws yooj yim ntawm kev siv thiab lub peev xwm ua haujlwm nrog cov cuab yeej siv tsawg.
Roj Tungsten Arc Vuam (GTaw)
GTAW, los yog Tig vuam, yog muaj npe rau nws qhov tseeb thiab qhov siab - zoo welds nws tsim tawm. Cov txheej txheem no siv tsis tau - consilable tungsten electrode los tsim hluav taws xob arc, thiab cov roj inert, yog siv los tuav ntawm weld cheeb tsam. Qhov tsis muaj cov neeg siv hluav taws xob tso cai rau kev tswj kom meej ntawm kev tswj cov vuam, ua rau cov neeg tua tsiaj kom tsim cov ntaub ntawv welders kom tsim cov ntaub ntawv huv thiab huv si.
Gtaw yog qhov tshwj xeeb tshaj plaws - haum rau vuam nyias cov ntaub ntawv thiab tsis yog - freals metrals xws li txhuas, magnesium, thiab tooj. Nws yog dav siv nyob rau hauv kev lag luam uas zoo nkauj thiab zoo ntawm Weld yog qhov tseem ceeb, xws li aerospace, thiab kev cai hlau, thiab kev cai hlau. Hauv kev lag luam Aerospace, GTAW tau siv los koom nrog cov khoom siv tseem ceeb ntawm cov cav dav hlau thiab airframes, ua rau lawv cov kev ntseeg siab thiab kev ua tau zoo.
Gas Hlau Arc Vuam (Gmaw)
GMAW, feem ntau hu ua mig vuam, yog ib semi - tsis siv neeg lossis tsis siv neeg vuam txheej txheem uas muaj cov khoom lag luam zoo siab thiab ua haujlwm zoo. Nws siv cov hlau txuas txuas ntxiv hluav taws xob thiab cov pa thaiv cov roj av, uas tuaj yeem yog cov roj lossis cov pa roj carbon dub. Cov hlau tau pub los ntawm kev siv phom sib tsoo, thiab arc ntawm cov hlau thiab cov hauv paus tso melts ob qho tib si, tso cov tub muab tub lim rau hauv weld sib koom tes.
Mig vuam yog paub rau nws tus nqi tso nyiaj siab, ua rau nws haum rau vuam tuab cov ntaub ntawv sai sai. Nws yog dav siv nyob rau hauv automotive kev lag luam rau huab hwm coj ntau lawm, nrog rau hauv kev tsim kho ntawm loj - nplai qauv. Nws yooj yim ntawm kev siv thiab hloov kho rau cov hlau sib txawv thiab cov thicknesses tau ua rau nws muaj kev xaiv nrov hauv ntau cov ntawv thov kev tsim khoom. Piv txwv li, hauv kev tsim cov tsheb lub tsheb lub cev, GMAW yog siv los sib dhos rau ntau cov panels, kom muaj cov qauv muaj zog thiab ruaj khov.
Flux - cored arc vuam (FCAW)
FCAW yog zoo ib yam li mig vuam tab sis siv flux - cored hlau es tsis txhob hlau. Lub flux nyob rau hauv cov hlau muab kev tiv thaiv thaum lub vuam txheej txheem thiab tseem ua rau muaj kev siv tshuaj lom neeg ntawm Weld, txhim kho nws cov khoom zoo. Txoj kev no yog qhov tshwj xeeb tshaj yog siv rau sab nraum zoov vuam daim ntawv thov, raws li cov xaim hluav taws xob sab nraum zoov, raws li cov xaim xaim cored tsawg dua los ntawm cua thiab lwm qhov chaw puag ncig piv rau cov neeg hlau siv hauv MIG vuam.
FCAW siv tau siv ntau nyob rau hauv kev tsim kho, shipbuilding, thiab pipeline vuam, qhov twg nws tuaj yeem lis cov khoom tuab thiab ua haujlwm hauv txhua txoj haujlwm vuam. Nws muaj qhov sib npaug zoo ntawm cov khoom lag luam thiab weld zoo, ua rau nws xaiv cov kev siv rau ntau cov ntawv thov kev lag luam.
Kuj vuam
Kuj vuam enccompasses ntau cov txuj ci, suav nrog cov chaw vuam, leeg vuam, thiab kev xoo hluav taws xob vuam. Cov hau kev no cia siab rau cov cua sov tsim los ntawm cov khoom siv hluav taws xob tsis kam. Thaum muaj hluav taws xob txuas ntxiv los ntawm cov ntaub ntawv, qhov tsis kam ntawm cov ntsiab lus tiv toj ua kom kub, yaj cov hlau thiab tsim ib lub weld thaum cua txias.
Chaw welding yog dav siv nyob rau hauv kev lag luam automotive rau kev koom nrog cov ntawv hlau feem, xws li lub cev lub cev panels. Cov leeg siv welding yog siv los tsim cov txuas ntxiv welds, feem ntau hauv kev tsim cov kav dej thiab ntim. TXHEEJ TXHEEM VUAM VUAM YUAV SIV Los koom nrog cov chaw nrog tsa khoom kwv yees lossis thawv paj no, tsim ntau yam velds ib txhij. Kuj yog vuam yog paub rau nws qhov nrawm, ua tau zoo, thiab muaj peev xwm tsim muaj zog, txhim khu kev qha Welds.
Cov txheej txheem Welding siab
Nyob rau hauv xyoo tsis ntev los no, kev siv vuam vuam tau tawm mus, qhib kev lag luam tshiab hauv ntau yam kev lag luam. Laser Beam vuam, piv txwv li, siv cov kab teeb laser rau cov duab ci thiab cov khoom siv. Nws muaj cov cua sov siab, lub cua sov nqaim - thaj chaw cuam tshuam, thiab muaj peev xwm weld ntau cov ntaub ntawv, suav nrog cov hlau tsis sib xws. Laser Beaj vuam yog siv nyob rau hauv cov khoom lag luam hluav taws xob rau kev koom nrog cov khoom siv kho mob me thiab hauv kev tsim kho mob kho mob rau kev tsim cov pob qij txha.
Kev siv hluav taws xob ci yog lwm cov txheej txheem siab uas siv cov nqaj ntawm lub siab - Zog hluav taws xob los tsim kom muaj cua sov. Nws muaj peev xwm ua lag luam sib sib zog nqus - nkag mus rau qhov tsis tshua muaj siab, ua rau nws haum rau cov vuam tuab ntawm cov siab - lub zog alloys. Electron nqaj vuam yog feem ntau siv nyob rau hauv Aerospace, nuclear, thiab defens kev lag luam rau cov ntawv qhia tseem ceeb uas siab dua cov khoom siv khoom zoo yog qhov tseem ceeb.
Hauv kev xaus, kev teb ntawm vuam muaj ntau cov tswv yim ntau yam ntawm nws tus kheej cov txiaj ntsig zoo thiab cov ntawv thov. Kev xaiv ntawm vuam txoj kev nyob ntawm ntau yam, xws li cov khoom siv, tuab, xav tau weld zoo, thiab daim ntawv thov tuab. Raws li thev naus laus zis txuas ntxiv mus ua ntej, peb tuaj yeem cia siab tias yuav tau txais kev txhim kho ntxiv hauv VUAM cov kev tsim tawm, ua kom zoo dua, thiab cov txheej txheem kev tsim khoom tshiab hla kev lag luam sib txawv.
