Yog chaw welding muaj zog dua li mig vuam?

Lub hauv paus rau phau ntawv

Vuam yog cov txheej txheem tseem ceeb hauv kev lag luam, tshwj xeeb hauv kev tsim khoom thiab kev tsim kho. Nws cuam tshuam nrog kev koom nrog ob lossis ntau daim hlau ua ke los tsim kom muaj zog thiab ruaj khov sib khi. Muaj cov txheej txheem sib txawv wel muaj ntau ntxiv, txhua tus nrog nws tus kheej zoo thiab qhov tsis zoo. Ob tug ntawm cov vuam vuam cov qauv vuam yog cov chaw vuam thiab mig (hlau inert roj) vuam. Kab lus no yuav tshawb txog qhov sib txawv ntawm cov chaw welding thiab mig vuam, thiab txiav txim seb hom twg muaj zog dua.

Dab tsi yog chaw vuam?

Chaw welding yog ib txoj kev tiv thaiv vuam uas siv cov cua sov tsim los ntawm hluav taws xob tsis kam koom nrog ob lossis ntau cov hlau ua ke. Tus txheej txheem no cuam tshuam nrog kev thov siab thiab dhau qhov siab tam sim no los ntawm cov ntsiab lus hlau, xws li 'muaj nyob hauv kev lag luam tawm hauv tsheb thiab cov khoom siv hauv tsheb.

Cov chaw vuam feem ntau cuam tshuam nrog ob lub tooj liab alloy electrodes, uas tau muab tso rau ob sab ntawm cov hlau los koom nrog. Lub electrodes siv siab rau cov hlau hlau, thiab thaum qhov siab tam sim no tau dhau los ntawm lawv, cov hlau ntawm cov electrodes melts thiab fuses ua ke. Weld yog tsim thaum molten hlau txias thiab solidifies, tsim kom muaj kev sib raug zoo ntawm cov hlau.

Chaw welding yog qhov ua tau zoo thiab muaj txiaj ntsig zoo rau kev koom nrog cov khoom siv nyias nyias, vim tias nws yuav tsum tau npaj me me thiab ua cov khib nyiab tsawg. Txawm li cas los xij, nws tsis haum rau koom nrog cov khoom siv thicker lossis rau cov ntawv thov uas yuav tsum tau txuas ntxiv weld, raws li cov cua sov tsim los ntawm cov txheej txheem ntawm cov electrodes.

Dab tsi yog MIG VUAM?

Mig vuam , tseem hu ua cov roj hlau hlau vuam Cov txheej txheem mig vuam suav nrog pub cov hlau electrode los ntawm kev sib tw phom, uas txuas nrog lub zog hluav taws xob thiab cov pa roj. Lub vuam rab phom yog nruab nrog cov lus qhia sib cuag, uas muab cov hlau electrode thiab cov roj inert rau ntawm thaj chaw weld.

Thaum lub sij hawm mig vuam, hluav taws xob arc yog tsim ntawm cov hlau electrode thiab workpiece. Qhov ARC no tsim kom muaj cua sov txaus kom sov rau ob lub xov hlau electrode thiab lub hauv paus hlau, tsim kom muaj kev sib raug zoo thaum lub molten hlau txias thiab solidifies. Cov roj inert, feem ntau yog sib cav lossis cov pa roj carbon dioxide, xws li oxygen kis, uas tuaj yeem ua rau muaj kev cuam tshuam weld.

Mig vuam yog ib hom vuam ntau thiab dav dav siv vuam txoj kev vuam, haum rau kev koom nrog ntau cov ntaub ntawv, suav nrog cov hlau, suav nrog cov hlau, thiab hlau stainless. Nws yog qhov tshwj xeeb zoo rau kev siv cov ntaub ntawv tuab, raws li cov hlau txuas ntxiv hlau electrode tuaj yeem muab cov lus qhia tshav dav hlau thiab tswj kev kub ntxhov. MIG vuam kuj tseem ua rau muaj kev huv thiab meej, nrog kev sib tw me me thiab tsis muaj kev xaiv kom yuag, ua rau nws xaiv qhov ua tiav zoo.

Kev sib piv ntawm Chaw Vuam thiab Mig Vuam

Ob lub chaw welding thiab mig vuam yog cov txheej txheem zoo rau koom nrog cov hlau, tab sis lawv muaj qee qhov sib txawv uas ua rau lawv haum rau cov ntawv thov sib txawv.

1. Cov khoom tuab: chaw welding yog feem ntau siv rau koom nrog cov ntawv hlau nyias nyias, feem ntau tsawg dua 3mm tuab. Cov txheej txheem tsim hluav taws xob hauv zos, uas yog txaus rau fusing cov khoom siv nyias tab sis yuav tsis haum rau cov khoom siv thicker. Mig vuam, ntawm qhov tod tes, yog haum rau ntau cov ntaub ntawv tuab, ntawm cov ntawv nyias nyias kom tuab cov phiaj. Cov hlau txuas txuas ntxiv hluav taws xob hauv MIG vuam muab cov tswv yim zoo ib yam, ua rau nws muaj peev xwm mus rau weld thicker cov ntaub ntawv.

2. Weld zoo: chaw vuam ua rau cov ntsiab lus Welds ntawm cov ntsiab lus tshwj xeeb, uas tuaj yeem ua kom muaj zog thiab ruaj khov thaum tsim nyog tua. Txawm li cas los xij, lub zog ntawm lub weld nyob ntawm xws li kev nyiam huv ntawm cov hlau, lub siab thov los ntawm cov hluav taws xob tam sim no. Mig vuam, ntawm qhov tod tes, tsim cov kev txuas ntxiv welds uas feem ntau ntawm cov khoom zoo, nrog qhov tsawg tshaj plaws thiab tsis muaj kev sib tw. Weld zoo hauv Mig vuam yog tsawg dua ntawm cov kev txawj ntawm tus neeg teb xov tooj, raws li cov txheej txheem yog tswj hwm thiab xwm yeem.

3. Ceev thiab ua tau zoo: chaw welding yog lub nrawm thiab muaj txiaj ntsig, tshwj xeeb rau cov neeg muaj feem ntawm cov hlau sib txuas. Cov txheej txheem yuav tsum tau npaj tsawg kawg thiab tuaj yeem kho tau yooj yim, ua rau nws haum rau kev siv xws li kev sib dhos kho tsheb. Mig vuam tseem yog cov txheej txheem nrawm thiab muaj txiaj ntsig, tab sis nws yog ntau ntau yam thiab tuaj yeem siv rau cov ntaub ntawv dav dav, suav nrog cov khoom siv dav dav thiab koom nrog cov hlau sib tshooj.

4. Cov khoom siv thiab tus nqi thiab tus nqi: chaw vuam tshuab feem ntau tsis tshua muaj nqi thiab yooj yim dua rau kev xaiv tau nqi ntau dua li mig kev xaiv zoo rau koom nrog cov ntawv nplaum nyias. Txawm li cas los xij, Mig vuam cov cuab yeej muaj ntau ntau yam thiab tuaj yeem siv rau cov kev xaiv dav dav, ua rau nws cov kev xaiv zoo ntxiv rau kev ua haujlwm loj dua.

Lub zog ntawm cov Welds

Lub zog ntawm cov velds tsim los ntawm chaw vuam thiab mig vuam yog nyob ntawm ntau yam, suav nrog cov ntaub ntawv tau ua, thiab kev txawj ntawm tus neeg teb xov tooj. Feem ntau, Mig vuam ua kom muaj zog dua welds dua li chaw vuam, tshwj xeeb thaum koom nrog cov khoom siv thicker. Qhov no yog vim qhov txuas ntxiv ntawm cov Mig Welds, uas muab cov kev sib tw zoo dua thiab sib raug zoo ib yam ntawm cov hlau.

Txawm li cas los xij, chaw vuam tuaj yeem tsim welds uas muaj zog npaum li meel hlau yog tswj cov khoom nyias nyias thaum koom nrog cov hlau ua kom huv thiab tsis muaj cov pa paug. Cov chaw welding tseem muaj txiaj ntsig zoo dua thiab siv tau nqi ntau lawm ntim cov hlau sib xyaw, raws li nws yuav tsum tau npaj tsawg kawg thiab tuaj yeem kho tau yooj yim.

Hauv cov ntawv thov uas Weld lub zog yog qhov tseem ceeb, xws li nyob rau hauv cov txheej txheem vuam tsim nyog thiab kev tswj hwm zoo, nws yog qhov kev tswj hwm zoo, nws yog qhov zoo li cov qauv tsim los ntawm txoj kev ua tiav cov lus qhia tshwj xeeb. Qhov no tuaj yeem suav nrog kev sim ua kom zoo thiab tsis yog kev ua kom muaj kev sib raug zoo thiab kev ncaj ncees ntawm cov kev kawm kom tsim nyog thiab cov ntaub ntawv pov thawj rau cov neeg siv vuam.

Hauv kev xaus, ob qho tib si Chaw welding thiab mig vuam yog cov txheej txheem zoo rau koom nrog cov hlau, tab sis lawv muaj cov khoom siv sib txawv thiab cov kev tsis sib xws uas ua rau lawv haum rau cov ntawv thov sib txawv. Chaw Welding yog cov txheej txheem nrawm thiab muaj txiaj ntsig zoo rau kev koom nrog cov qauv hlau, thaum koom nrog ntau yam khoom siv thiab cov thicknesses.

Thaum txiav txim siab uas vuam txoj kev vuam muaj zog dua, nws yog qhov tseem ceeb kom xav txog cov ntawv thov tshwj xeeb thiab cov ntaub ntawv tau koom nrog. Feem ntau, Mig vuam ua kom muaj zog dua welds ntau dua li cov ntaub ntawv uas tsuas yog muaj zog npaum li Mig Welds thaum koom nrog cov ntawv hlau. Thaum kawg, kev xaiv ntawm vuam txoj kev yuav nyob ntawm cov yam uas zoo li cov khoom siv thickness, weld kev xav tau zoo, thiab kev txiav txim siab weld.
