Tam sim no nws tsis tuaj yeem xav txog kev tsim khoom uas tuaj yeem ua yam tsis muaj kev pabcuam vuam. Cov txheej txheem no, raws li ib txoj hauv kev los txuas tag nrho qhov sib txawv ntawm cov khoom siv ruaj khov, tau pom daim ntawv thov dav tshaj plaws. Qhov tseeb, feem ntau, vuam yog tib txoj hauv kev zoo los txuas cov hlau thiab cov qauv. Nrog rau qhov kev thov no, kev nce qib ntawm cov thev naus laus zis no tsis tuaj yeem tos thiab txhim kho hauv cov kauj ruam nrog lub sijhawm. Hauv qab no peb yuav saib cov ntsiab lus tseem ceeb thiab cov qauv ntawm kev vuam niaj hnub.
MIG, MMA welding
Kev Taw Qhia Hlau Arc txhais ua lus Lavxias li "kev tuav arc vuam nrog cov nplaum electrodes". Txoj kev sib txuas no yog ib qho pioneer hauv txoj kev vuam kev vam meej. Cov txheej txheem zoo li no tsis tshua muaj thev naus laus zis ntau dua li lwm tus, uas peb yuav tham hauv qab no, tab sis txog rau hnub no tseem muaj kev ntseeg siab tshaj plaws.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm yog raws li hauv qab no: ob qho tib si electrode thiab cov khoom siv welded tau muab cov khoom ncaj nraim los yog hloov tam sim no los hlawv cov vuam arc. Cov electrode siv ib qho arc los txuas qhov chaw ntawm cov hlau, tsim ib lub pas dej ntawm cov hlau thiab electrode,Nyob rau tib lub sijhawm, molten slag tuaj rau saum npoo ntawm seam.
Kev nce qib ntawm cov tshuab vuam
Ntawm vuam thev naus laus zis nrog qhov ntsuas MIG, MAG, TIG yog ib txoj hauv kev niaj hnub tshaj plaws ntawm arc vuam thiab tau siv los ntawm txhua qhov chaw ntawm theem no ntawm kev txhim kho kev lag luam hauv ntiaj teb. Ib tug novice welder tsis tas yuav paub tias nws yog dab tsi - MIG / MAG vuam. Lub ntsiab lus ntawm cov txheej txheem no yog raws li nram no: qhov no yog cov txheej txheem ntawm kev koom tes ntawm cov hlau, nyob rau hauv uas ib tug tshwj xeeb shielding gas yog nkag mus rau lub burning cheeb tsam ntawm lub hluav taws xob arc, thawb atmospheric gases tawm ntawm cheeb tsam ntawm cov hlau yog welded. Qhov no yog kev tiv thaiv kev ua haujlwm ntawm cov pa roj. Hauv MIG welding, lub pas dej welding muaj kev tiv thaiv tag nrho ntawm oxygen thiab nitrogen.
Qhov sib txawv ntawm MIG thiab MAG vuam
Txawm li cas los xij, tus kws tshaj lij welder paub tias nws yog dab tsi - MIG thiab MAG vuam, cov hom no txawv ntawm ib leeg. Qhov sib txawv yog nyob rau hauv lub npe thiab lawv txhais lus. MIG (Metal Inert Gas) yog txhais ua "hlau, inert gas".
Argon yog ib qho ntawm cov roj inert. Cov roj no muaj feem cuam tshuam rau vuam aluminium, tooj liab, titanium thiab lawv cov alloys ntau yam. MAG (Metal Active Gas) yog txhais los ntawm lus Askiv li "hlau, active gas". Cov pa roj no suav nrog oxygen, carbon dioxide thiab hydrogen. Cov roj no yog siv rau vuam pas dej ua ke ntawm cov hlau tsis tshua muaj hlau, tsis yog-alloy thiab corrosion resistant steels.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab semi-automatic welding
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov khoom siv semiautomatic feem ntau yog cov hlau electrode nws tus kheejuas, nyob rau hauv phau ntawv arc vuam, tus kws tshwj xeeb pub nws tus kheej nrog kev pab los ntawm ib tug tes thiab ib tug tuav, nyob rau hauv ib tug semiautomatic ntaus ntawv nws yog pub siv lub cav. Yog li, txoj kev no yog hu ua semi-automatic MIG vuam. Cov hlau ua haujlwm dual - nws yog ob qho tib si conductive electrode thiab cov khoom muab tub lim. Cov hluav taws xob tam sim no tau siv sai ua ntej lub electrode tawm ntawm lub teeb, thiab qhov tshwm sim ntawm hluav taws xob arc tshwm sim ntawm qhov kawg ntawm cov hlau electrode thiab hlau.
Cov roj thaiv thaiv yog muab los ntawm cov roj nozzle nyob ib puag ncig cov hlau electrode. Cov roj hlawv, vim yog inertia, displaces tag nrho cov atmospheric gases, txuag lub zog ntawm cov qauv ntawm welded seam. Txawm li cas los xij, ntxiv rau kev tiv thaiv kev ua haujlwm, cov pa roj kuj tseem ua haujlwm rau peripheral. Qhov muaj pes tsawg leeg ntawm cov huab cua nyob rau hauv cheeb tsam ntawm cov hluav taws xob arc nyob ntawm lub shielding gas, uas kuj muaj txiaj ntsig zoo rau nws cov hluav taws xob conductivity.
TIG welding
Tsis zoo li MIG vuam, Tungsten Insert Gas yog phau ntawv arc vuam ua nrog cov khoom siv hluav taws xob tsis siv tau hauv qhov chaw tiv thaiv roj los ntawm kev ntxiv cov xaim. Hom no tseem hu ua argon arc vuam. Lub ntsiab ntawm cov txheej txheem no yog raws li nram no: ib tug tiv thaiv gas yog pub rau hauv arc cheeb tsam los ntawm ib lub nozzle, thaum lub non-consumable tungsten electrode tsis melted, tab sis yog siv los ua ib lub cuab tam rau xaim insertion.
Raws li kev faib tawm, TIG, MIG, MMA vuam belongs rau hauv chav kawm ntawv arc. Hom vuam no tau pom zoo rau kev koom nrog cov khoom me me nrog qhov sib txawv mus txog0.01mm ib. Lub ntsiab tsis zoo ntawm TIG vuam, piv rau MIG vuam, yog qhov ceev, uas yog qeeb heev. Yog tias koj tab tom nrhiav rau qhov zoo tshaj plaws thiab koj tsis maj nrawm, qhov no yog qhov kev xaiv zoo tshaj plaws rau kev zoo nkauj welder.
Kev Pom Zoo rau Vuam Tshuab
Nyob rau hauv tsab xov xwm no, peb tau paub nrog lub ntsiab hom vuam uas yog nrov thiab nyob rau hauv kev thov tam sim no nyob rau hauv feem ntau cov lag luam loj thiab nyob rau hauv tech chains. Niaj hnub no, MIG welding, TIG technologies, stick electrode welding, thiab lwm yam yog siv. Txawm li cas los xij, peb tsis tau hais txog txoj kev tsis siv neeg ntawm kev koom nrog cov khoom siv hauv kev lag luam.
Yog tias peb delve rau hauv lub ntiaj teb ntawm cov thev naus laus zis uas tab tom txhim kho, peb tuaj yeem taug qab qhov kev nyiam rau kev tswj hwm kev sib koom ua ke, thaum teeb tsa qhov ntsuas ntawm cov tshuab tsis siv neeg, piv txwv li, qhov tuab ntawm cov hlau raug welded, teeb tsa qhov sib xws. hlau pub ceev, vuam tam sim no thiab lwm yam tsis. Qhov no ua rau kom muaj kev nplij siab ntawm kev ua haujlwm thiab kev tsim khoom. Ntawm lwm yam, tam sim no, nyob rau hauv lub xyoo pua 21st, vuam yog ib qho kev ywj pheej ntawm kev tsim khoom thiab pab txhawb rau kev tsim cov qauv tsim tshiab. Welded qhov chaw ua hauj lwm nyob rau hauv ultra-siab thiab ultra-tsawg kub, ntawm pressures, thiab muaj peev xwm ua hauj lwm txawm nyob rau hauv qhov chaw nqus tsev vacuum.
Cov thev naus laus zis niaj hnub hauv kev vuam tso cai rau koj ua haujlwm txawm tias nrog cov yas, iav, ceramics thiab lwm yam ntaub ntawv. Tsis ntev los no, vuam tau siv txawm los txuas cov ntaub so ntswg. Yog li ntawd, qhov notxoj hauj lwm yuav txhim kho, txhim kho thiab nyob twj ywm raws li qhov xav tau raws li nws tau ua thoob plaws hauv keeb kwm ntawm tib neeg thiab kev vam meej. Thiab kev ua haujlwm ntawm cov kws tshaj lij no yuav thiab tseem tseem ceeb thiab tsim nyog.
