Brazing rau Vuam Hluav Taws Xob Nyiaj Sib Txuas Lus Sib Txuas yog ib txoj kev vuam uas ob qho tib si brazing alloy thiab cov khoom ua haujlwm tau rhuab rau lawv qhov kub thiab txias, thiab cov kua brazing alloy ua rau cov khoob hauv cov khoom ua haujlwm los tsim cov hlau nplaum. Thaum lub sij hawm brazing, cov khoom yog rhuab mus rau ib tug kub me ntsis siab tshaj cov khoom muab tub lim, ua rau cov muab tub lim hlau liquefy, npog tag nrho cov mating nto, thiab tsim ib tug metallurgical daim ntawv cog lus. Ua ntej brazing, oxide zaj duab xis thiab roj ntawm qhov chaw sib chwv ntawm cov ntaub ntawv hauv paus yuav tsum tau muab tshem tawm kom tso cai rau cov capillary ua haujlwm tom qab lub brazing alloy melts, ua rau cov dej ntub dej thiab capillary flowability ntawm brazing alloy.
Classification ntawm Brazing
Raws li lub melting point ntawm brazing alloy, brazing yog muab faib ua nyuaj brazing thiab mos brazing.
(1) Mos Brazing:Lub melting point ntawm lub brazing alloy nyob rau hauv mos brazing yog qis dua 450 degree, ua rau lub zog sib koom ua ke (tsawg dua 100MPa). Mos brazing feem ntau yog siv rau vuam conductive, airtight, thiab watertight li nyob rau hauv lub electronics thiab zaub mov industries, thiab yog ib tug lwm txoj rau Resistance Butt Welding Silver Hu rau thaum qis dua - qhov kub thiab txias yog xav tau. Tin- txhuas alloy brazing yog hom kev sib txuas ntawm brazing alloy. Mos solder feem ntau yuav tsum tau flux kom tshem tawm cov oxide zaj duab xis thiab txhim kho cov wettability ntawm cov solder.
(2) Hard soldering:Lub melting point ntawm hard solder yog siab tshaj 450 degree, thiab lub zog sib koom ua ke siab dua (ntau tshaj 200MPa). Cov pob qij txha tawv tawv muaj lub zog siab, thiab qee qhov tuaj yeem ua haujlwm ntawm qhov kub thiab txias. Muaj ntau hom tawv solders, nrog txhuas, nyiaj, tooj liab, manganese, thiab npib tsib xee-raws li solders yog siv dav tshaj plaws; ntawm cov no, nyiaj-raws li cov tshuab feem ntau yog ua haujlwm hauv Copper Spot Welding Silver Contact assemblies kom ruaj ntseg nyiaj rau ntawm lub shank.
Raws li cov cua kub qhov chaw, nws tuaj yeem muab faib ua ntxiv rau:
(1) Hlau soldering:Cov cuab yeej siv yooj yim, hloov tau yooj yim, haum rau micro- soldering, yuav tsum tau flux, thiab tsuas yog siv tau rau cov muag muag muag thiab cov khoom me me.
(2) nplaim taws soldering:Cov cuab yeej siv yooj yim, kev hloov pauv tau zoo, tab sis nyuaj los tswj qhov kub thiab txias, thiab tsuas tuaj yeem ua cov khoom me me xwb. Nplaim taws soldering yog ib txoj hauv kev uas siv cov nplaim hluav taws uas tsim los ntawm kev sib xyaw ntawm cov roj combustible, combustible khoom lossis kua roj nrog oxygen lossis cua kom sov lub workpiece thiab Silver Solder. Qhov ntau ntawm brazing muab tub lim hlau yog dav, los ntawm qis- kub nyiaj-raws li cov khoom siv hlau mus rau siab- kub nickel thiab tooj liab-raws li cov khoom siv hlau. Yuav luag tsis muaj qhov yuav tsum tau ua ntawm cov duab ntawm cov hlau muab tub lim; hlau-zoo li, daim ntawv-zoo li, ua ntej- tsim, lossis muab tshuaj txhuam-zoo li cov hlau muab tub lim tuaj yeem siv rau hauv cov nplaim taws.
(3) Hlau da dej brazing:Cov cua kub ceev ceev, qhov kub thiab txias tuaj yeem tswj tau qhov tseeb, tab sis cov khoom siv hlau siv tau siab heev. Nws yog siv rau cov mos brazing thiab nws cov khoom loj, tshwj xeeb tshaj yog rau luv luv - voj voog khiav ntawm Hluav Taws Xob Sib Txuas Sib Txuas.
(4) ntsev da dej brazing:Lub brazing alloy yog sib sau ua ke thiab muab tso rau hauv ib lub molten ntsev da dej. Lub da dej tuaj yeem ua kom sov los ntawm hluav taws xob, roj, lossis lwm yam roj. Cov ntsev heats lub workpiece, melting lub muab tub lim hlau. Cov txheej txheem no muaj cov cua kub ceev ceev thiab tswj qhov kub thiab txias, tab sis cov cuab yeej siv tau siab, thiab cov khoom siv yuav tsum tau ntxuav tom qab vuam. Nws yog siv rau kev tsim khoom loj thiab tsis tuaj yeem txuas cov khoom ua haujlwm; Nyiaj rau tooj liab Brazing feem ntau ua nyob rau hauv nruab nrab no.
(5) Vapor theem brazing:Cov cua sov yog sib xws, thiab cov brazing zoo yog siab. Nws yog siv rau cov mos brazing thiab loj ntau lawm.
(6) Resistance brazing:Kev ua haujlwm siab ntau lawm thiab tus nqi qis, tab sis kev tswj qhov kub thiab txias yog qhov nyuaj, thiab cov duab thiab qhov loj ntawm lub workpiece raug txwv. Qhov no yog ib txoj kev brazing uas siv cov hluav taws xob tiv thaiv los ntawm qhov tam sim no dhau los ntawm cov khoom ua haujlwm, cov hlau muab tub lim, lossis qhov chaw sib cuag ntawm cov hlau muab tub lim thiab cov khoom ua haujlwm kom sov thiab yaj cov hlau muab tub lim- ib txoj hauv kev feem ntau siv hauv Copper Spot Welding Silver Contact fabrication.
(7) Induction brazing:Induction brazing muab qhov chaw rau brazed nyob rau hauv ib qho chaw sib nqus sib nqus. Qhov kev tiv thaiv ntawm qhov induced tam sim no nyob rau hauv coils muab tso rau ib ncig ntawm lub workpiece muab cua sov rau lub induction brazing txheej txheem, melting lub pre- muab tub lim hlau los ntawm cov cua sov. Cov txheej txheem no tso cai rau xaiv cov cua sov ntawm lub workpiece tsuas yog qhov xav tau, thiab muaj cov cua kub ceev, zoo brazing zoo, thiab cov kev txwv ntawm workpiece puab, ua rau nws haum rau batch brazing ntawm me me nyiaj thiab tooj liab vuam khawm hu.
(8) Brazing nyob rau hauv lub qhov cub tiv thaiv roj:Txoj kev no muab cov cua sov zoo sib xws, qhov deformation tsawg, feem ntau tsis tas yuav tsum muaj flux, tab sis cua sov qeeb, thiab cov hlau muab tub lim thiab cov khoom ua haujlwm yuav tsum tsis txhob muaj cov ntsiab lus tsis zoo. Nws yog tsim rau batch zus tau tej cov loj thiab me me thiab brazing ntawm workpieces nrog ntau brazing seams.
(9) Nqus Brazing:Txoj kev no suav nrog kev tso cov khoom ua haujlwm nrog cov khoom siv hlau sib sau ua ke hauv lub tshuab nqus tsev rau cua sov thiab brazing. Nws tso cai rau kev tswj qhov kub thiab txias, cov cua sov tsis sib xws, qhov deformation tsawg, thiab tuaj yeem ua kom nyuaj- mus rau - vuam siab - kub alloys. Nws tsis xav tau flux thiab muab zoo brazing zoo, thiab feem ntau yog siv rau brazing tseem ceeb workpieces. Tam sim no, ntau dua AMB (Active Metal Brazing) thev naus laus zis kuj tseem yog lub tshuab nqus tsev vacuum. AMB koom nrog kev siv Ag-raws li cov khoom siv uas muaj cov khoom nquag Ti thiab Zr ntawm qhov kub ntawm ib ncig ntawm 800℃kom ntub thiab hnov mob ntawm qhov sib cuam tshuam ntawm ceramic thiab hlau, yog li ua tiav kev sib raug zoo ntawm cov ceramic thiab hlau.
Txheej txheem yam ntxwv ntawm Brazing
Tsawg kub:Lub melting point ntawm Silver Solder yog qis dua li cov hlau uas tau koom nrog. Yog li ntawd, cov hlau raug koom nrog tsis yaj thaum lub sij hawm kev sib txuas; tsuas yog cov filler hlau melts. Yog li, qhov yuav tsum tau ua kom sov kub yog qhov tsawg.
Tsis muaj kev puas tsuaj rau lub Component nto:Vim qhov qis melting point ntawm lub brazing muab tub lim hlau, qhov zoo ntawm qhov sib txuas ntawm cov hlau tsis muaj kev puas tsuaj thaum lub sij hawm kev sib txuas, khaws cia cov tsos thiab kev ua tau zoo ntawm tus thawj Sib cuag Vuam Cheebtsam.
Kev siv dav dav:Brazing tuaj yeem siv los koom nrog ntau hom ntaub ntawv, xws li cov hlau sib txawv, hlau - mus rau - kev sib txuas tsis yog hlau, thiab txawm tias fiber ntau thiab dispersion - cov ntaub ntawv sib xyaw ua ke, ua rau nws siv dav hauv ntau yam lag luam thiab thaj chaw, tshwj xeeb tshaj yog rau Kev Sib Txuas Hluav Taws Xob.
Kev ntseeg tau muaj zog:Silver to Copper Brazing muab kev sib txuas muaj zog thiab ruaj khov, ua rau cov khoom siv muaj zog thiab ua haujlwm ntev.
Tsis xav tau cov ntaub ntawv zoo ib yam:Piv nrog rau lwm txoj kev vuam, tooj liab Spot Vuam Nyiaj Sib cuag tsis tas yuav tsum tau koom nrog cov hlau thiab muab tub lim hlau kom muaj qhov sib xws. Cov yam ntxwv no ua rau brazing ib qho tseem ceeb ntawm kev sib koom siv hlau, siv dav hauv ntau lub teb.
