Cov lus nug ntawm seb Mig (cov roj av hlau) vuam siv tau rau cov hlau qub yog ib qho uas feem ntau ntawm cov neeg nrhiav cov txheej txheem ua tau zoo thiab txhim khu kev qha ntau yam rau cov khoom siv ntau yam no. Cov lus teb yog qhov tseeb yog-}}} mig tsuas yog muaj peev xwm siv tau ntawm kev lag luam thoob plaws, kev tsim khoom, thiab txawm tias qee yam zoo nkauj.
MIG vuam, tseem hu ua GMAW (roj roj hlau arc vuam), ua haujlwm los ntawm kev pub mis cov hlau elever, uas ua raws li cov tub luam yeeb cov khoom siv thiab arc. Cov roj tiv thaiv tau muab tso tawm los ntawm cov phom tiv thaiv kom tiv thaiv lub pas dej Weld Weld los ntawm covmosceric kis. Rau cov hlau stainless, tus txheej txheem no tau yoog raws li cov khoom siv chromium tshwj xeeb tab sis kuj xav tau meej tswj hwm cov tswv yim tshav kub thiab thaiv.
Ib qho ntawm cov ntsiab lus tseem ceeb ua rau MIG VUAM Cov xov hlau no feem ntau muaj chromium (18-20%) thiab npib tsib xee (8-12%
Kev xaiv roj Puv yog qhov sib luag tseem ceeb rau kev vam meej mig vuam ntawm stainless hlau. Tsis zoo li cov hlau me me mig vuam, uas tuaj yeem siv cov pa roj carbon dioxide (co₂) lossis khaws cia cov khoom siv ntawm cov khoom siv xeb thiab cov khoom siv. Kev sib xyaw ntawm 98 {- 99%} 99%}}}}}}}}}}}}}}}}}}}} paab, thiab tiv thaiv cov chromium depetion hauv thaj chaw weld. Rau cov ntawv thov ntau dua, xws li high {{{purity lossis qis} kev sib xyaw (arless
Mig vuam muaj ntau yam zoo rau cov ntawv thov hlau stainless. Ua ntej, nws yog lub siab - Cov txheej txheem Weld, lub ntsiab lus} nplai rau cov haujlwm loj lossis tuab {}} Qhov kev ua tau zoo no txo cov nqi thiab cov nqi zog piv piv rau cov txheej txheem qeeb li Tig vuam. Thib ob, nws yog qhov yooj yim rau kev siv tau, tso cai rau kev siv tshuaj zoo ib yam li kev lag luam ua khoom noj, tshuaj lom neeg cov hlau, qhov twg cov hlau uas stainless hlau feem ntau siv.
Txawm li cas los xij, Mig welding welding steel siv tsis tas yuav ua tib zoo saib xyuas kom tsis txhob muaj ntau qhov chob. Cov tswv yim tshav kub yuav tsum tswj kev ua rog, raws li stainless hlau muaj qis thermal conductivity tshaj li cov hlau me me, ua rau hauv zos overheating. Taug kev mus ncig ua si thiab voltage chaw yuav tsum yog qhov zoo tshaj plaws: dhau nrawm tuaj yeem ua rau nkag mus ntau dhau thiab kev loj hlob ntau dhau yuav ua rau lub ntsej muag thiab porosity heev. Tsis tas li ntawd, kev tu kom zoo ntawm lub hauv paus hlau {{}}}} yog qhov tseem ceeb ntawm cov av tuaj yeem ua rau weldosity lossis tawg.
Lwm qhov kev txiav txim siab yog qhov kev xaiv ntawm cov xaim xaim xaim thiab flux - cored mig rau stainless hlau. Cov hlau ua hlau, ua khub nrog cov roj tiv thaiv kom yog, yog qhov kev xaiv txheem rau feem ntau cov ntawv thov, muab cov neeg ua haujlwm zoo hauv Weld zoo thiab corrosion tsis kam. Flux - Cored xov hlau, uas muaj cov pa roj teeb lossis cua hlob sab nraum zoov uas cuam tshuam. Txawm li cas los xij, lawv tuaj yeem tawm ntawm slag uas yuav tsum tau tshaj tawm pos ... 5}} Weld tu thiab yuav tsis phim lawv cov kev siv rau tsis- tseem ceeb app.
Hauv kev xaus, MIG vUAM Nws nrawm, ua haujlwm rau kev xaiv tshuab ua rau nws xaiv qhov uas nyiam tshaj plaws hauv kev lag luam uas stabless corrosion thiab durability yog qhov tseem ceeb. Nrog cov txheej txheem tsim nyog thiab kev saib xyuas kom nthuav dav, mig vuam muab cov qauv stainless hlau uas tau raws li cov qauv kev ua tau zoo ntawm cov qauv kev ua haujlwm niaj hnub thiab kev tsim khoom.
