Dab tsi yog brazing

Brazing yog tus txheej txheem sib koom ua ke uas cuam tshuam nrog kev siv cov tub lim hlau, uas tau muab khi thiab faib ua ob lossis ntau dua. Cov txheej txheem no yog qhov txawv ntawm nws qhov kub thiab txias, qhov twg cov hlau hauv paus tsis yaj tab sis yog rhuab rau qhov kub siab tshaj 450 ° C (txog 842 ° F). Tus muab tub lim hlau feem ntau muaj qhov taw tes melting saum no qhov kub thiab qis dua li ntawm cov haujlwm no. Brazing yog dav siv nyob rau hauv ntau yam kev lag luam vim nws cov hauj lwm zoo hauv kev tsim cov muaj zog, ruaj pob pob qij txha.

Tus txheej txheem brazing

Cov txheej txheem brazing tuaj yeem tawg rau hauv ntau theem tseem ceeb:

1. Kev npaj ntawm cov chaw: Cov chaw ntawm cov hlau yuav tsum tau ua kom huv kom tshem tawm cov tshuaj oxides, lossis roj. Qhov no tuaj yeem ua tiav los ntawm cov txheej txheem ntxuav kev sib tsoo xws li sib tsoo lossis khau khiab, lossis cov qauv siv tshuaj xws li pickling.

2. Sib Dhos: Tom qab tu, cov khoom sib xyaw ua ke nyob ze qhov sib ze, ua kom nruj. Cov txheej txheem tsim nyog yog qhov tseem ceeb vim tias qhov chaw nruab nrab ntawm qhov cuam tshuam rau cov neeg muab tub lim rau cov neeg muab tub lim thiab ua kom zoo.

3. Cua sov: Cov Txheej Txheem yog tom qab ntawd rhuab siv ntau txoj kev, suav nrog lub teeb ci, cub tawg, ua ntu zus, lossis kev tawm tsam kev tawm tsam. Cov cua kub yuav tsum muaj kev sib xws txaus kom ncav cuag qhov ntsuas kub uas tsis tas yuav ua rau lub hauv paus ntawm cov hlau me me kom yaj.

4. Daim ntawv thov ntawm cov tubtiv hlau: Thaum cov cuab yeej ua haujlwm txaus yog cov muab tub lim, uas feem ntau nyob rau hauv daim ntawv ntawm cov pas nrig, nplooj ntawv, lossis hmoov, tau qhia. Nws yog kos rau hauv kev sib koom ua ke los ntawm capillary txiav txim. Tus muab tub lim hlau ces ntws mus rau hauv qhov sib txawv ntawm cov hlau nplaum, sib sau ua ib daim ntawv cog lus zoo li nws ua tau zoo.

5. Cua txias thiab ua tiav: Tom qab sib koom ua ke tiav lawm, nws raug tso cai rau txias, thiab muaj ntau dhau ntawm cov hlau sib tsoo tuaj yeem raug tshem tawm los ntawm machining lossis sib tsoo. Lub tiav ua ke yog feem ntau raug kuaj kom ntseeg tau tias cov sib koom ua ke ua tau raws li cov lus qhia tshwj xeeb.

Qhov Zoo Ntawm Brazing

Brazing muaj ob peb qhov zoo piv rau lwm txoj kev koom nrog vuam lossis soldering. Ib qho ntawm cov txiaj ntsig tseem ceeb yog lub peev xwm koom nrog cov hlau tsis sib xws. Qhov muaj peev xwm no tseem ceeb hauv kev lag luam uas cov khoom siv sib txawv, xws li hauv kev tsim kho cua sov, kho cov khoom siv hluav taws xob, thiab khoom siv hluav taws xob.

Lwm qhov txiaj ntsig tseem ceeb yog qhov txo thermal cuam tshuam rau ntawm cov haujlwm. Txij li thaum cov hlau ua hauv paus tsis yaj thaum lub sijhawm ua tiav, tsis muaj kev pheej hmoo ntawm kev ntaus rog lossis hloov pauv lub cev zoo li kev tawv thiab lub zog. Cov xeeb ceem no tseem tso cai rau cov ntaub ntawv dav dav los koom nrog, suav nrog cov uas nyuaj rau Weld.

Tsis tas li ntawd, Brazed cov pob qij txha feem ntau nthuav tawm cov khoom siv zoo, ua rau haum rau cov ntawv thov kom muaj zog thiab ua kom muaj zog. Tus txheej txheem kuj tso cai rau kev tsim cov geometies uas tej zaum yuav nyuaj rau ua tiav nrog lwm cov kev koom nrog kev koom nrog lwm txoj kev koom nrog.

Cov ntawv thov ntawm Brazing

Brazing yog siv hauv ntau qhov kev lag luam, suav nrog:

Automotive: Hauv kev lag luam automotive, feem ntau yog siv los koom nrog cov khoom siv hluav taws xob, tso pa tawm, thiab xa cov chaw sib dhos.

Aerospace: Hauv kev lag luam Aerospace, hla mus sib sau ua ke xws li cov pa tshuab hluav taws xob thiab cov pa taws kub, qhov kev ntseeg tau kub.

Cov khoom siv hluav taws xob: Brazing yog siv los tsim kev sib txuas hauv cov khoom siv hluav taws xob, muab kev sib raug zoo rau cov khoom siv uas yuav tsum tiv thaiv cov cua sov thiab kev ntxhov siab.

Cov kav dej: Hauv cov kav dej thiab HVAC thiab Brazing yog ib txoj kev sib txuas nrog cov kav dej thiab cov fittings, ua kom muaj kev sib txuas xau.

Hauv cov ntsiab lus, Brazing yog cov txheej txheem tseem ceeb hauv kev tsim kho niaj hnub thiab kho cov txheej txheem, muab cov pob qij txha tsis muaj zog yam tsis muaj kev xav tau ntawm cov hlau ua hauv paus. Nws cov vagatility, kev ua tau zoo, thiab muaj peev xwm koom nrog cov khoom sib cais ua nws cov cuab yeej invaluable thoob plaws ntau yam lag luam. Raws li thev naus laus zis kev nce qib, cov ntawv thov thiab cov qauv ntawm brazing txuas ntxiv hloov zuj zus, ntxiv txhim kho nws qhov tseem ceeb hauv kev tsim khoom thiab tsim khoom.
