Tsis muaj dab tsi ua rau koj chim siab dua li siv koj tus pas nrig vuam los ntaus ib qho arc, tsuas yog yuav muaj cov kab tawg, porosity, lossis qhov vuam tsis muaj zog uas yuav tsis ruaj khov. Txawm tias koj tab tom kho cov khoom siv ua liaj ua teb hauv thaj teb lossis tsim cov qauv hlau hauv khw, tus pas nrig vuam yog ib qho txheej txheem ua haujlwm hnyav - tab sis nws feem ntau yuav muaj teeb meem uas txawm tias cov kws tshaj lij paub dhau los ntsib. Phau ntawv qhia no txiav cov lus sib txuas lus kom kho cov teeb meem pas nrig vuam uas ntxhov siab tshaj plaws sai sai, yog li koj tuaj yeem rov qab los tsim cov vuam muaj zog, huv si txhua lub sijhawm.
Yam Koj Yuav Tsum Paub Txog Cov Ntsiab Lus Tseem Ceeb ntawm Weld Stick & Cov Yam Ntxim Saib ntawm Kev Lag Luam
Tus pas vuam, uas yog lub hauv paus ntawm kev vuam tes rau ntau xyoo lawm, vam khom lub electrode uas siv tau uas muaj cov flux los tsim ib lub arc, yaj hlau, thiab tsim ib qho weld. Tsis zoo li MIG lossis TIG welding, nws yooj yim nqa tau, tiv taus cua, thiab ua haujlwm rau cov khoom qias neeg lossis tuab - ua rau nws tseem ceeb rau kev tsim kho, kho cov kav dej, kev saib xyuas cov tshuab hnyav, thiab cov haujlwm sab nraum zoov. Lub flux txheej yog qhov tseem ceeb: nws hlawv kom tso cov pa roj tiv thaiv thiab tsim cov slag, tiv thaiv lub pas dej weld los ntawm cov pa phem. Tab sis ntawm no yog qhov ntes - qhov yuam kev me me hauv kev khaws cia, kev teeb tsa parameter, lossis cov txheej txheem tuaj yeem ua rau koj txoj haujlwm tsis zoo. Cia peb dhia mus rau hauv cov kev kho rau cov teeb meem uas koj yuav ntsib ntau zaus.
Cov Teeb Meem Sab Saum Toj ntawm Weld Stick & Yuav Kho Li Cas
1. Qhov porosity
Qhov porosity yog tus yeeb ncuab ntawm qhov vuam muaj zog - cov qhov me me, zoo li npuas dej ua rau qhov sib koom ua kom tsis muaj zog thiab ua rau muaj kev ua qias tuaj. Cov neeg ua txhaum tseem ceeb? Dej noo, cov hlau hauv paus qias neeg, lossis qhov ntev ntawm lub arc tsis raug.
Cov Kev Daws Teeb Meem:Ib txwm khaws cov pas vuam rau hauv qhov chaw qhuav nrog cov av noo qis dua 60%, thiab lawv ua ntej siv - cov electrodes acidic xav tau 150-250 ° C, thaum cov yooj yim xav tau 350-400 ° C. Ntxuav cov hlau hauv paus nrog lub tshuab sib tsoo kom tshem tawm xeb, roj, lossis xim. Khaws koj lub arc luv luv kom tiv thaiv huab cua los ntawm kev sib xyaw rau hauv lub pas dej vuam. Yog tias vuam sab nraum zoov, tiv thaiv thaj chaw ntawm cua, uas rub cov pa phem mus rau hauv cov yaj.
2. Electrode Lo rau ntawm qhov chaw ua haujlwm
Cov neeg tshiab thiab cov kws tshaj lij ib yam nkaus ntxub thaum ib qhotus pas nrig vuamnplaum nws tus kheej rau ntawm cov hlau. Qhov no feem ntau tshwm sim los ntawm qhov hluav taws xob qis, qhov pib qeeb qeeb, lossis lub electrode puas lawm.
Cov Kev Daws Teeb Meem:Ua kom lub zog vuam me ntsis—saib cov lus qhia ntawm lub tuam txhab tsim hluav taws xob rau qhov loj ntawm koj tus pas vuam. Thaum ntaus ib qho arc, siv txoj kev khawb thiab tsa lub electrode sai sai kom tsim tau qhov arc. Yog tias nws lo, maj mam co lub electrode lossis kov nws rau ntawm cov hlau kom tawg—tsis txhob rub, uas tuaj yeem ua rau lub txheej electrode puas tsuaj.
3. Kev Muaj Slag (Slag Uas Tau Kaw Hauv Qhov Weld)
Cov slag yog cov tawv nqaij uas tshuav tom qab vuam, tab sis yog tias nws raug ntes hauv qhov vuam, nws tsim cov chaw tsis muaj zog. Qhov no tshwm sim thaum cov slag yav dhau los tsis raug ntxuav, tam sim no qis dhau, lossistus pas nrig vuamviav vias dav dhau.
Cov Kev Daws Teeb Meem:Siv rab rauj thiab txhuam hlau los txiav cov slag tawm ntawm txhua qhov hla - tsis txhob hla cov kauj ruam no. Ua kom cov dej ntws ntau ntxiv kom ntseeg tau tias nkag mus tag nrho thiab ua kom qhov vuam ceev dua, uas tiv thaiv cov slag kom tsis txhob poob rau hauv lub pas dej vuam. Ua kom koj tus pas vuam nqaim kom cov slag tsis txhob nthuav tawm dhau thaj chaw yaj.
4. Kev txiav hauv qab (Cov qhov raws ntug vuam)
Qhov txiav hauv qab ua rau muaj cov kab me me raws cov hlau hauv paus, ua rau lub zog ntawm qhov vuam txo qis thiab tsim cov ntsiab lus ntxhov siab. Nws yog tshwm sim los ntawm cov hluav taws xob ntau dhau, cov kab ntev, lossis lub kaum sab xis ntawm tus pas vuam tsis raug.
Cov Kev Daws Teeb Meem:Txo qhov tam sim no thiab ua kom lub arc luv luv. Kho koj lub kaum sab xis ntawm tus pas vuam kom txog 15-30 degrees piv rau cov hlau tseem ceeb - qhov no ua kom muaj kev faib cua sov sib npaug. Txo koj qhov kev mus ncig ceev thiab siv cov xov nqaim dua los sau cov npoo kom tag. Yog tias ua haujlwm ntawm cov vuam ntsug lossis saum toj kawg nkaus, tig lub electrode me ntsis rau sab saud kom tswj tau qhov yaj.
5. Arc Blow (Kev Mus Los Arc Tsis Ruaj Khov)
Qhov tawg ntawm cov hlau nplaum (arc blow) tshwm sim thaum lub zog sib nqus nyob ib puag ncig qhov vuam ua rau cov hlau nplaum tawg, ua rau yaj tsis sib npaug. Nws yog ib qho uas tshwm sim nrog cov hlau nplaum lossis cov kev sib txuas hauv av tsis sib npaug.
Cov Kev Daws Teeb Meem:Rov qab muab lub clamp av tso ze rau thaj chaw vuam kom sib npaug ntawm lub zog sib nqus. Siv qhov ntev ntawm lub arc luv dua los tswj lub arc. Yog tias vuam rau ntawm cov hlau sib nqus, ua kom cov khoom sov me ntsis lossis hloov mus rau AC vuam tam sim no, uas txo cov kev cuam tshuam sib nqus.
Cov Lus Qhia Zoo rau Kev Ua Haujlwm Tsis Tu NcuaCov pas nrig vuamCov txiaj ntsig
Ntxiv rau kev kho cov teeb meem, cov cwj pwm no yuav ua rau koj txoj haujlwm vuam zoo dua:
Txuas tus pas nrig txuas rau cov hlau puag - siv E6013 rau cov hlau dav dav thiab E7018 rau cov ntawv thov muaj zog heev.
Tsis txhob cia cov electrodes qhuav raug cua ntau tshaj 4 teev - rov ziab lawv yog tias muaj dej noo.
Xyaum ua kom qhov kev mus ncig ceev tas li - ceev dhau ua rau cov vuam tsis tob, qeeb dhau ua rau kub dhau thiab cuam tshuam.
Kev vuam siv txoj hlua khi ua rau yooj yim thiab hloov tau yooj yim, tab sis kev paub txog nws txhais tau tias paub yuav ua li cas daws teeb meem sai sai. Los ntawm kev daws cov teeb meem no thiab ua raws li cov kev coj ua zoo tshaj plaws, koj yuav tsim cov vuam txhim khu kev qha uas sawv cev rau qhov kev thov ntawm kev lag luam - txawm tias koj yog tus pib kawm cov hlua lossis tus kws tshaj lij txhim kho koj cov khoom siv tes ua.
