Dab tsi ceev kuv yuav tsum tau teeb tsa kuv MIG VUAM HLAU RAU?

Qhov ceev ntawm cov vuam hlau yog pub rau hauv weld pas {}}} - yog qhov tseem ceeb cuam tshuam weld zoo. Nws txiav txim siab qhov amperage (cov lus qhia sov), tso nyiaj rau, thiab arc stability, ua qhov tseem ceeb kom tau txoj cai, zoo nkauj welds. Cov hlau uas zoo tshaj plaws pub ceev yog nyob ntawm peb qhov tseem ceeb: co kab uas hla, thiab xaim hom. Los ntawm kev ua raws li cov xwm txheej no, koj tuaj yeem txiav txim siab ntawm kev ua siab ntev rau koj qhov project.
Pib Taw: Hlau Hla
Kab hlau xaim yog lub hauv paus rau kev teeb tsa hlau pub ceev. Thicker cov xov hlau yuav tsum tau pub nrawm nrawm nrawm nrawm thiab tso nyiaj txaus los sau ntawm Weld sib koom tes. Ntawm no yog cov qauv hlau pub ceev ntau ntau rau cov neeg sib txawv ntawm cov hlau diam hlau, raws li kev lag luam kev lag luam:
• Siv hlau luam tawm 0.023-nti: Qhov nyias hlau nyias yog tsim los rau cov khoom noj ua haujlwm ntawm 24-16 lub ntsuas cua (0.5-1.6mm) khoom. Nws cov hlau pub ceev ceev feem ntau yog ranges los ntawm 100-200 nti ib feeb (IPM). Ntawm qis kawg (100-150 ipm), nws ua haujlwm tau zoo rau 24-20 lub ntsuas cua hlau, xws li cov qauv siv hluav taws xob me me lossis cov ntawv cua sov me me tiv thaiv kev ua rog. Ntawm 150-200 IPM, nws tuaj yeem siv 18-16 lub ntsuas cua hlau, ntsuas ntsuas qhov chaw nkag thiab qhov tseeb.
• 0.030 {- nti hlau: feem ntau ntau yam uas tshaj tawm, haum rau 1/4-nti (1.9-6.4mm) steel. Nws cov hlau pub ceev spans 175-300 ipm. Rau 14-16 lub ntsuas cua hlau (1.6-1.9mm), 175-225 ipm muab cov cua sov txaus rau kev sib tw tsis muaj kev hlawv-dhau. Rau cov khoom siv thicker (1 / 8-1 / 4 nti), 225-300 ips ua rau muaj kev sib koom ua ke, ua rau nws zoo tagnrho rau cov nkhaus, thav duab, lossis fab fab.
• 0.035 - nti hlau: tsim rau nruab nrab {29mm), cov hlau tuab no siv cov pub mis ceev ntawm 250-400 ip. Rau 1 / 8-3 / 16 Nti (3.2-4.8mm) Hlau, 250-325 IPM muab kev nkag mus. Rau 3 / 16-3 / 8 nti (4.8-9.5mm) hlau, 325-400 hack nce-zoo meej rau cov qauv txheej txheem xws li cov kab hlau lossis cov khoom siv machinery.
• 0.045 {- nti hlau: siv rau cov hlau hnyav rau ntawm 1/4-ntiv tes (6.4mm) Rau 1 / 4-3 / 8 nti (6.4-9.5mm) hlau, 350-450 thiab50 ipm muab tob nkag. Rau 3/8 nti thiab saum toj no, 450 ip ua rau nws xaiv cov khoom siv ceev ceev rau kev siv hluav taws xob vuam lossis kho cov cuab yeej siv hnyav.
Feem ntau MIG Welders tau ua - hauv cov duab kos uas sau cov lus pom zoo, yog li pib nrog cov kab mob voos thiab cov ntaub tuab.
Kev kho kom haum rau hauv paus pib tuab
Thaum co xaim inch tau teeb tsa ntau yam, lub hauv paus hlau tuab zoo {}}}} nkauj lub suab ceev. Thicker hlau xav tau kev pub ceev ceev kom tsim ntau dua cov cua sov (ntau dua amperage) rau kev nkag mus. Ntawm no yog yuav kho li cas nyob rau hauv lub taub - Raws li ranges:
• Cov hlau nyias (hauv qab no 1/8 nti): Nyob ntawm qis dua ntawm cov hlau ceev. Piv txwv li, 0.030 - nti hlau rau ntawm 16 lub koob iav ua haujlwm zoo tshaj plaws ntawm 175-200}
• Nruab nrab hlau (1 / 8-1 / 4 nti): tsom rau nruab nrab ntawm cov ntau. Lub tshuab 0.035-nti ntawm 3/16 nti hlau ua tau zoo ntawm 300 IPM, ntsuas kub thiab tso tawm.
• Cov hlau tuab (saum toj 1/4 nti): Siv lub siab tshaj plaws ntawm qhov ntau. Ib qho ntawm 0.045-nti hlau rau ntawm 3/8 nti hlau xav tau 500-600 IPM kom ntseeg tau tias tus weld penetrasy txaus kom muab cov khoom tuab.
Nco ntsoov ntsuas ntawm ib daim scrap ib qho ntawm tib tuab raws li koj qhov project ua ntej. Yog tias tus weld muaj kev nkag tsis zoo (pom qhov khoob), nce qhov ceev los ntawm 25-50 ipm. Yog tias nws hlawv los ntawm, txo nws los ntawm tib tus nqi.
Hloov kho rau Hlau Hom
Hom Mig Hlau - cov khoom lossis flux -}}}}}} Tseem cuam tshuam rau pub mis ceev. Flux - Txoj hlua hlau yuav tsum tau ceev dua ceev kom ntseeg tau tusyees sab hauv thiab tiv thaiv lub pas dej weld:
• Cov hlau xaim (piv txwv li, ER70s-6): Cov xov hluav taws xob cia siab rau kev tiv thaiv, yog li lawv txoj kev ceev no feem ntau yog txiav txim siab los ntawm txoj kab uas hla thiab cov khoom tuab. Piv txwv li, 0.030-nti cov khoom hlau ntawm 1/8 nti steel ua haujlwm tau zoo ntawm 225 IPM. Lub hom phiaj yog lub arc ruaj khov uas melts cov hlau thiab hauv paus hlau uniformly tsis muaj sputtering.
• Flux - cored Mig Hlau (piv txwv li E71} {{10} {{10} {} Ib 0.035- nti flux-cored hlau-cored hlau-cored hlau-corch hlau, uas yuav siv hlau, ua haujlwm zoo dua thaum 300 IPM. Qhov no ua kom cov flux tsim cov pa roj txaus thiab cov txheej sleag-yog tias lub ntsej muag ci ntsa iab-yog tias lub ntsej muag ci lossis tsis sib luag, ua kom nrawm dua.
Cov khoom siv -} kev txiav txim siab tshwj xeeb
Cov hlau sib txawv coj ua kev sib txawv thaum tshav kub sib txawv, xav tau kev hloov kho me me txawm tias tib lub taub hlau thiab tuab:
• Steel me: cov ntaub ntawv zam txim tshaj plaws. Ua raws li cov qauv ceev ceev, yog cov hlau me me ntawm cov ntsiab lus muaj roj carbon ntau cov ntsiab lus ntau yam tsis muaj teeb meem.
• Stainless hlau: Stainless hlau khaws kub ntau dua li cov hlau me me, yog li qeeb me ntsis) pab tiv thaiv kev tiv thaiv corrosion tsis kam. Piv txwv li, 0.035-nti er308 hlau ntawm 3/16 nti Stainless ua haujlwm zoo tshaj plaws ntawm 275 IPM hloov 300 IPM.
• Txhuas Txhuas: Txhuas Txhuas ua kom kub sai sai, yog li nrawm dua (5-10% siab dua) kom cov pob zeb txaus kom sau ua ntej kub dissipates. Ib qho 0.035-nti Er4043 hlau ntawm 1/8 nti aluminium xav tau 325 ipm hloov 300 IPM kom muaj kev nkag siab.
Yuav ua li cas paub yog tias qhov nrawm yog qhov tseeb
Txawm hais tias nrog cov lus qhia, koj yuav tsum tau zoo - xem. Saib cov paib no yog koj cov hlau pub ceev yog txoj cai:
• Kev nrawm: Ib txoj kev ncaj ncees Weld hlaws dai nrog txawm nkag mus, tsawg heev, thiab khov kho "ntawm arc. Cov xov hlau melts xwm yeem, thiab chav weld ntws mus rau hauv kev sib koom ua ke yam tsis muaj qhov khoob.
• Ua qeeb heev: cov arc sputters lossis lo rau hauv paus hlau, tsim kom muaj qhov nqaim, tsis xwm yeem nrog nkag tsis zoo. Cov hlau yuav tsis yaj sai txaus, ua rau "txias lapping" (tsis muaj nuj nqis). Nce nrawm los ntawm 25 ipm.
• Ceev heev: ntau lub ncauj lus, dav, tiaj tiaj, lossis hlawv - los ntawm. Cov xaim hluav taws xob sai dua li nws muaj peev xwm yaj, ua rau nws txhaws lossis tawg los ntawm hlau nyias. Txo qis los ntawm 25 ipm.
Cov lus qhia zaum kawg rau kev teeb tsa ceev
• Siv Welder daim ntawv: Pib nrog lub khw muag khoom siv nrawm rau koj cov kab hlau thiab cov ntaub ntawv thickness {}} Qhov no yog koj lub hauv paus.
• Kuaj rau seem: ib txwm xyaum rau ntawm ib daim ntawm cov hlau uas phim koj qhov project tuab thiab cov khoom siv. Qhov no cia koj hloov yam tsis muaj lub sijhawm koj ua haujlwm.
• Khib nrog voltage: hlau pub ceev ua haujlwm nrog voltage - nrawm nrawm dua voltage kom yaj cov hlau. Feem ntau cov welders kho voltage ncaj nrog nrawm, tab sis yog tias koj tsis, volts thaum muaj ntau dua 50 ipm.
Xaus: Sib Pauv Ceev Nrog Cov Khoom Siv Thiab Hlau Hom
Qhov zoo tagnrho mig vuam hlau ceev yog qhov sib npaug ntawm xaim inch, puag hlau cov tuab, thiab xaim hlau. Pib nrog cov kev pom zoo rau koj cov hlau lub cheeb, kho rau cov ntaub ntawv tuab, thiab tweak raws li xaim hom thiab hlau conductivity. Nrog kev soj ntsuam thiab kev soj ntsuam, koj yuav pom qhov ceev uas ua kom muaj zog, ntxuav Welds txhua zaus. Nco ntsoov: xwm yeem yog qhov tseem ceeb txawm tias kev hloov kho me me tuaj yeem ua qhov sib txawv loj hauv Weld zoo.
