Cov lus teb yog qhov muaj tseeb yog - mig (hlau inert roj) vuam tsis yog tsuas yog ua tau rau txoj kev nrov thiab tau zoo hauv ntau txoj kev lag luam. Nrog rau cov khoom siv tau, cov ntaub ntawv, thiab cov tswv yim, mig vuam tuaj yeem tsim muaj zog, ua nws haum rau kev ua zaub mov ua khoom noj rau cov kws kho zaub mov.
Qhov tseem ceeb yuav tsum muaj rau Mig vuam vuam stainless hlau
Khoom Teeb Khoom
Mig Welder muaj peev xwm tuav cov hlau stainless yog qhov tseem ceeb. Tsis zoo li Mig vuam me hlau, uas tuaj yeem siv cov khoom siv hluav taws xob yooj yim los ntawm cov tshuab hluav taws xob yooj yim feem ntau cov txiaj ntsig Ntau cov mig mig niaj hnub no tuaj nrog "Stainless hlau" chaw, tab sis txawm tias cov qauv yooj yim tuaj yeem ua haujlwm yog tias siv tau.
Cov hlau pub khoom haus yuav tsum tau tshaj nrog cov hlau vuam hlau, uas yog qhov nyuaj thiab tsawg dua li cov hlau xaim me me. Ib qho kev du {{{{}}}}}}}}}}}}}}}}}}} qhov tseem ceeb rau kev zam kev tsis xws luag hauv Weld.
Vuam Hlau thiab Kev thaiv cov roj
Stainless Hlau Mig vuam yuav tsum muaj cov xaim xaim tshwj xeeb. Cov hom feem ntau yog 308L thiab 316L, uas phim rau corrosion tsis kam ntawm nrov stainless hlau qib (304 thiab 316, ntsig txog). Qhov "l" qhia tias tsawg cov ntsiab lus carbon, uas txo qhov kev pheej hmoo ntawm carbide nag lossis} {}} be} cuam tshuam cheeb tsam (Haz) ze ntawm Weld.
Kev thaiv cov roj yog lwm tus tsis - sib tham. Tsis zoo li cov hlau me me, uas tuaj yeem siv kev sib xyaw ntawm Argon thiab carbon dioxide, stainless hlau, tiv thaiv cov weld los ntawm oxygen thiab nitrogen, uas ua rau muaj kev tiv thaiv thiab porosity. Ib qho kev tiv thaiv roj rau stainless hlau mig vuam yog 98% argon nrog 2% oxygen, uas tso dag rau arc thiab ua rau muaj kev sib tw weld. Rau cov ntaub ntawv tuab lossis siab dua {{6} Pre} Pre6 {} makon, thiab ib qho me me ntawm cov pa oxygen) yuav siv rau kev nkag mus thiab txo lub ntsej muag.
Base Hlau Npaj
Kev npaj tsim nyog ntawm cov stainless hlau hauv paus hlau yog qhov tseem ceeb. Stainless hlau yog nquag ua rau paug los ntawm roj, av, lossis txawm tias muaj hlau hlau los ntawm kev sib tw hlau me me, uas tuaj yeem ua rau muaj xeb me me hauv weld cheeb tsam. Ua ntej vuam, qhov saum npoo yuav tsum tau huv si nrog lub stainless- Cov hlau- Cov roj tov thiab roj. Rau xeb lossis nplai, xaim txhuam (tsim rau cov hlau stainless tsuas yog siv cov cuab yeej stainless discitive, vim lawv tuaj yeem tawm cov hlau tawm.
Qhov ntawm cov workpieces yuav tsum khaws cov neeg ua haujlwm tsawg (zoo tagnrho 0.5mm lossis tsawg dua) kom ntseeg tau tias nws muaj kev phom sij rau lub zog ua kom sov, uas tuaj yeem ua rau nws cov tshuaj tiv thaiv zoo heev lossis ua kom nws cov khoom tiv thaiv.
Cov tswv yim rau kev vam meej Stainless Hlau MIG VUAM
Kev Tswj Cua Sov
Stainless hlau muaj qis dua thermal conductivity tshaj li cov hlau me me, lub ntsiab lus nws khaws cov cua sov ntev dua. Qhov no ua rau nws xav txog kev ua rog thiab kub siab heev, uas tuaj yeem discolor cov hlau (tig nws xiav lossis xim dub) thiab tsis muaj zog ntawm lub taub hau. Txhawm rau zam qhov no, siv cov cua sov qis dua li koj yuav ua rau cov hlau me me ntawm tib tuab. Piv txwv li, thaum vuam {16 - pa (1.6mm) 304 volts ib feeb thiab ib qho hluav taws xob pub dawb ntawm lub suab (lub suab nrov ""
Mus ncig ceev kuj tseem ceeb heev. Kev mus ncig nrawm nrawm nrawm nrawm nrawm, tiv thaiv kev kub ntxhov. Txawm li cas los xij, nws yuav tsum tau sib npaug nrog cov neeg nkag txaus - nrawm heev, thiab cov weld yuav tsis muaj fusion; qeeb heev, thiab cov hlau yuav warp.
Arc thiab Hlau Pub
Tswj luv luv, ruaj khov arc kom txo tau qhov tseeb thiab tiv thaiv lub pas dej weld ntawm covmosceric kis. Cov hlau yuav tsum pub tau yooj yim rau hauv arc, nrog cov ntsis ntawm cov xaim tsuas yog chwv lub pas weld pas dej. Tus txheej txheem "laub" (tuav lub teeb ntawm 10-15℃lub kaum, raws li nws txhim kho kev pheej hmoo ntawm cov xaim uas tau daig hauv Weld.
Khaws cov lus sib tiv toj ze rau lub workpiece - qhov tseeb tsis pub dhau 1/4 mus rau 3/8 ntawm ib nti. Ib qho kev ncua ntev nce cov caij nyoog ntawm arc tsis muaj peev xwm thiab porosity.
Post - Weld Saib Xyuas
Tom qab vuam, tu Weld yog tus yuam sij rau kev khaws cia stainless hlau lub corrosion. Siv tus pas hlau stainless hlau txhuam los tshem tawm ib qho kev swb los yog lub ntsej muag thaum cov hlau tseem sov (tab sis txias kom huv). Rau cov ntawv tseem ceeb, xws li cov khoom noj qib qib, passivation-}}}}} yuav tsim nyog los txhim kho oxide txheej.
Zam kev sib tsoo cov weld tshwj tsis yog tsim nyog kiag li, raws li nws tuaj yeem nthuav cov hlau tsis muaj kev tiv thaiv hlau. Yog tias kev sib tsoo uas xav tau, siv cov hlau uas muaj mob siab rau lub log thiab taug qab nrog tus txhuam hniav kom tshem tawm cov khoom seem.
Qhov Zoo Ntawm Mig Vuam Stainless Hlau
MIG vuam muaj ntau cov txiaj ntsig rau cov haujlwm stainless hlau. It's faster than TIG (Tungsten Inert Gas) welding, making it ideal for high - volume production. Nws tseem yuav tsum muaj tsawg tus neeg teb xov tooj tshaj lij tshaj li Tig, tab sis kev xyaum yog tseem xav tau los pab tswj kub. Cov kav hlau pub dawb tso cai rau Welds ntev dua yam tsis tau nres hloov cov electrodes, txhim kho kev ua tau zoo.
Thaum ua tiav kom raug, MIG vAs ntawm cov hlau stainless muaj zog thiab muaj zoo corrosion desistance - sib piv rau hauv paus hlau. Qhov no ua rau txoj kev haum rau ob qho kev siv thiab hniav.
Txwv los txiav txim siab
Mig vuam stainless hlau tsis yog tsis muaj kev cov nyom. Nws yuav tsum muaj cov ntaub ntawv kim dua li cov xaim hluav taws xob me me: roj hlau tshwj xeeb tshaj li Argon - kev sib xyaw. Nws kuj tseem tsis yog qhov kev xaiv zoo tshaj plaws rau cov hlau tsis muaj nyias tus (hauv qab 14 lub koobtsheej {{Tig vuam yog qhov zoo dua rau cov xwm txheej zoo li no, raws li nws muaj ntau txoj kev tswj.
Sab nraum zoov VUAM Nyob rau hauv cov xwm txheej zoo li no, muaj cua screen lossis cov roj ntws ntau dua (30-40 cubic feet (30-40 cubic feet (30-40
Hauv kev xaus, Mig vuam stainless hlau tsis yog tsuas yog ua tau tab sis ib qho kev xaiv tau rau ntau cov ntawv thov. Nrog rau cov khoom siv yog (kho tau Mig Welder), cov ntaub ntawv hlau (kev tswj hwm kom zoo (kho cua sov) Txawm hais tias koj ua haujlwm ntawm kev lag luam tshuab lossis kev cai hlau kev sib tw muaj qhov sib npaug ntawm kev nrawm, ua tau zoo, thiab ua tau zoo rau cov phiaj xwm stainless hlau.
