Dab tsi yog qhov kev daws teeb meem rau qhov qis qis ntawm tooj liab Brazing tshuab?

Qhov teeb meem ntawm qhov qis qis ntawm lub tshuab tooj liab brazing tuaj yeem cuam tshuam nrog ntau yam, suav nrog cov khoom siv brazing, cua sov kub, sib koom ua ke sib txawv thiab qhov chaw nyob. Thaum daws qhov teeb meem, nws yog ib qho tsim nyog los xyuas thiab kho cov txheej txheem tsis zoo ib qho los ntawm ib qho raws li qhov xwm txheej tshwj xeeb. High-zoo brazing tuaj yeem tsis tsuas yog txhim kho cov khoom lag luam, tab sis kuj txo cov nqi tsim khoom.

1. Xaiv cov khoom siv brazing zoo

Rau cov khoom siv tooj liab, phosphor tooj liab brazing khoom lossis cov khoom siv nyiaj-raws li brazing yog pom zoo. Hom brazing cov ntaub ntawv no muaj zoo wettability thiab fluidity thiab yog haum rau tooj liab brazing.

2. Txhim kho cua sov kom zoo

Xyuas kom meej tias qhov kub ntawm qhov vuam mus txog qhov melting point ntawm cov khoom siv brazing thiab sib npaug sib npaug ntawm qhov kub ntawm qhov vuam; nruab nrab-frequency induction cua sov lossis cov cuab yeej tswj qhov kub thiab txias tuaj yeem siv los txhim kho qhov ntsuas kub kom raug.

3. Kho qhov sib koom ua ke

nruj me ntsis tswj qhov sib koom ua ke nyob rau hauv qhov kev pom zoo los xyuas kom meej tias qhov kev txiav txim ntawm capillary tuaj yeem ua lub luag haujlwm tag nrho thiab cov khoom siv brazing tuaj yeem ntws thiab sau qhov sib txawv.

4. Ntxuav qhov vuam nto

Ua ntej welding, grind, degrease los yog pickle lub tooj liab nto kom tshem tawm oxide zaj duab xis thiab av thiab txhim kho cov adhesion ntawm cov khoom siv brazing.

5. Optimize vuam txoj hauj lwm tsim

Sim tsim cov weld nyob rau hauv txoj hauj lwm kab rov tav, siv lub ntiajteb txawj nqus thiab capillary nkaus los pab cov solder ntws; Yog tias tsim nyog, siv lub vuam fixture los txhim kho lub workpiece kom ntseeg tau tias lub kaum sab xis vuam tsim nyog.
