Soldering hlau vuam txoj kev thiab vuam cov kauj ruam rau loj tshav kub muaj peev xwm vuam qhov chaw
1. Kev tuav vuam tshuab
① Peb txoj kev tuav cov hlau nplaum thaum vuam
② Yuav ua li cas tuav cov hlau nplaum
③ Ntxuav thiab tinning ntawm qhov chaw vuam ua ntej vuam.
④ Xuas tes tuav lub vuam kub thiab lub sijhawm.
⑤ Tswj cov cua sov kom zoo los ntawm cov pob qij txha.
2. Vuam cov kauj ruam rau loj kub muaj peev xwm weldments
Rau weldments nrog lub peev xwm loj dua me ntsis, siv tsib kauj ruam vuam txoj kev:
① Kev Npaj: Muab cov khoom yuav tsum tau welded, soldering hlau, solder hlau, soldering hlau sawv, flux, thiab lwm yam. Thaum tshav kub kub thiab ntxuav qhov chaw ua hauj lwm ntawm cov hlau soldering, thiab siv ib tug me me ntawm solder.
② Cua sov lub workpiece yuav tsum tau welded: Muab lub soldering hlau taub rau ntawm vuam taw tes kom sov lub soldering point; qhov chaw ua hauj lwm ntawm cov hlau taub hau yog coated nrog solder kom ceev tus nqi cua sov. Yog hais tias muaj ntau tshaj ob yam ntawm ib tug soldering point, sim ua kom sov lub vuam qhov chaw ntawm tag nrho cov welded qhov chaw nyob rau tib lub sij hawm.
③ Melting solder: Thaum lub solder sib koom yog rhuab mus rau qhov chaw ua hauj lwm kub, tam sim ntawd kov lub solder hlau mus rau lub vuam nto ntawm lub welded ib feem. Lub solder hlau yuav tsum tau ntxiv nyob rau hauv cov kev taw qhia ntawm lub soldering hlau taub, tab sis yuav tsum tsis txhob ncaj qha mus kov lub soldering hlau taub.
④ Tshem tawm cov hlau nplaum: Thaum cov hlau nplaum melts mus rau qhov tsim nyog, nws yuav tsum raug tshem tawm sai.
⑤ Tshem tawm cov hlau soldering: Tom qab qhov sib koom ua ke tau tsim tab sis cov flux tsis evaporated, sai sai tshem cov hlau soldering.
Rau weldments nrog lub peev xwm me me, cov txheej txheem ua haujlwm tsib kauj ruam saum toj no tuaj yeem ua kom yooj yim rau hauv txoj kev ua haujlwm peb kauj ruam:
① Kev Npaj: Tuav lub preheated, ntxuav thiab tin-lined hluav taws xob soldering hlau nyob rau hauv koj sab tes xis, tuav lub soldering hlau ze rau ntawm lub taub hau ntawm koj sab laug tes, thiab xav tias txoj hauj lwm yuav tsum tau soldered, raws li qhia nyob rau hauv daim duab (a) .
② Cua sov lub workpiece thiab solder hlau nyob rau tib lub sij hawm: kov lub soldering hlau thiab solder hlau mus rau lub vuam taw tes ntawm ob sab ntawm lub workpiece nyob rau tib lub sij hawm, thiaj li hais tias ib tug tsim nyog tus nqi ntawm solder melts thiab nyob rau hauv vuam ib feem, raws li qhia hauv daim duab (b).
③ Tshem tawm cov hlau thiab cov hlau nplaum tib lub sijhawm: Thaum lub vuam sib koom ua ke thiab cov cua sov mus txog, tshem cov hlau thiab cov hlau nplaum tib lub sijhawm.
