Qhov sib txawv ntawm kev ua yeeb yam thiab fusion vuam

Vuam thiab Branzing yog ob ntawm cov txheej txheem feem ntau siv los koom nrog cov hlau, tab sis lawv ua haujlwm ntawm cov qauv sib txawv thiab raug suav rau cov ntawv thov sib txawv. Nkag siab txog qhov sib txawv ntawm kev sib txawv thiab fusion vuam yog qhov tseem ceeb rau cov engineers, cov ntaub thaiv, thiab txhua tus neeg koom nrog kev tsim cov txheej txheem. Cov ntawv tshawb fawb txog cov ntsiab lus tseem ceeb ntawm Brazing thiab fusion vuam, nrog rau cov txheej txheem, cov ntaub ntawv, cov tswv yim, kev siv ntawm txhua txoj kev.

Txhais thiab Txheej Txheem

Brazing yog cov hlau-koom nrog uas tsis cuam tshuam melting ntawm cov hlau ua haujlwm. Hloov chaw, nws ua haujlwm ib tug muab tub lim hlau, uas muaj qhov qis dua melting taw tes dua li cov workpieces, feem ntau tshaj 450 ° C (842 ° F). During brazing, the base metals are heated, causing the filler metal to melt and flow into the joint through capillary action. Raws li cov kev sib dhos ua kom txias, tus muab tub lim hlau khov kho, tsim kom muaj kev sib raug zoo ntawm nruab nrab ntawm cov cheebtsam.

Fusion vuam, ntawm qhov tod tes, koom nrog melting ob lub hauv paus cov hlau thiab cov muab cov khoom siv (yog tias siv) ntawm lawv cov chaw koom nrog. Cov txheej txheem tsim cov tsiaj pas dej molten uas ua rau kom txias thaum txias, ua kom sib txuas tas mus li. Fusion vuam encompasses ntau txoj kev xws li arc vuam, roj vuam, laser vuam, thiab hluav taws xob vuam. Tus yam ntxwv tseem ceeb ntawm fusion vuam yog tias nws tso siab rau lub tiav melting ntawm cov hlau tau koom nrog.

Qhov Kub Saib Xyuas Kub

Ib qho ntawm kev sib txawv ntawm kev sib txawv ntawm kev nkag mus thiab fusion vuam yog qhov kub ntawm txhua tus txheej txheem tshwm sim. Brazing yog ua nyob rau ntawm qhov kub qis dua, uas txhais tau tias nws tuaj yeem siv los koom nrog cov ntaub ntawv uas yuav rhiab rau cov cua sov. Qhov kev tswj hwm thermal no pab txo qis warping, distortion, thiab kev hloov pauv hauv cov khoom siv khoom.

Nyob rau hauv kev sib piv, fusion vuam yuav muaj qhov kub siab uas feem ntau ntau tshaj qhov taw tes melting ntawm lub hauv paus cov hlau. Qhov kev hloov pauv kub no tuaj yeem ua rau hloov pauv hauv microstructure ntawm cov hlau tau welded. Thaum lub sijhawm no yuav muaj txiaj ntsig zoo nyob rau qee kis, xws li tsim cov pob qij txha tsis tshua muaj zog, nws tseem tuaj yeem ua rau cov kev sib tw xws li muaj cov khoom siv kub tsis muaj zog.

Cov hlau cev quav

Lwm qhov kev sib txawv tseem ceeb nyob hauv kev siv cov tub lim. Nyob rau hauv brazing, tus muab tub lim hlau tshwj xeeb xaiv tau kom muaj qhov taw tes melting qis dua li ntawm cov hlau ua haujlwm. Cov Khoom Siv Ua Si nrog tooj liab, nyiaj, thiab aluminium alloys. Kev xaiv ntawm tus muab tub lim hlau yog tsim los txhim kho cov khoom sib koom ua ke, xws li corrosion tsis kam thiab lub zog.

Nyob rau hauv kev sib sau vuam, ib tug muab tub lim hlau yuav los yog siv tsis tau, nyob ntawm txoj kev ua haujlwm. Thaum cov khoom siv ua haujlwm yog ntxiv, nws yog feem ntau xaiv los phim cov khoom ntawm cov hauv paus ntawm cov cuab yeej siv tau zoo. Qhov no kom ntseeg tau tias lub pob qij welded khaws lub zog thiab ductility ntawm cov ntaub ntawv qub.

Ob leeg tsim thiab haum

Brazing tso cai rau kev tsim nyog rau kev tsim nyog hauv kev sib koom ua ke dua li kev sib txuas vuam. Lub capillary kev ua ntawm Molten chais tau tuaj yeem sau qhov khoob ntawm cov ntawv uas tau koom nrog cov pob qij txha nrog cov pob qij txha nrog cov pob qij txha sib npaug. Qhov no tuaj yeem ua tau zoo thaum ua haujlwm nrog cov khoom siv tsis xwm yeem lossis cov kev sib tham uas yuav tsum tau ua kom tsis txhob muaj kev tsim nyog.

Fusion vuam, ntawm qhov tod tes, xav tau ntau dua kev kub tshaj-up ntawm cov hlau los xyuas kom muaj kev vam meej weld. Qhov khoob lossis misalignments tuaj yeem ua rau muaj zog lossis tsis tiav kev sib koom ua ke, qhia txog qhov tseem ceeb ntawm kev sib dhos ua ntej vuam.

Qhov Zoo
