I. Kev npaj
Npaj cov yeeb nkab tooj liab uas yuav tsum tau muaj, cov khoom siv vuam xws li cov khoom siv thiab cov khoom siv vuam, thiab cov khoom siv vuam xws li rab phom vuam. Npaj cov cuab yeej tsim nyog suav nrog cov yeeb nkab pliers, wrenches, sandpaper, thiab hlau txhuam. Tshawb xyuas qhov zoo ntawm cov yeeb nkab tooj liab kom paub tseeb tias tsis muaj kab nrib pleb thiab tsis muaj kev puas tsuaj ua ntej kev teeb tsa.
II. Ntxuav cov yeeb nkab tooj liab
Siv cov ntawv xuab zeb los yog txhuam txhuam los txhuam cov khoom siv ntawm cov yeeb nkab tooj liab, tshem tawm cov oxides thiab cov av los ntawm ob lub raj kawg thiab sab hauv ntawm qhov haum. So cov yeeb nkab tooj liab nrog ib daim ntaub huv kom ntseeg tau tias qhov vuam yog huv thiab qhuav. Kev tu kom zoo yog qhov tseem ceeb rau kev txiav txim siab capillary los kos cov hlua rau hauv qhov sib koom ua ke.
III. Sib sau cov yeeb nkab tooj liab
Sib sau cov yeeb nkab tooj liab kom raug soldered kom raug thiab xyuas kom tseeb tias cov khoom sib txuas tau zoo sib xws. Siv cov yeeb nkab pliers lossis wrenches los kho cov yeeb nkab kom zoo, tab sis tsis txhob dhau -ntxo, kom tsis txhob cuam tshuam qhov zoo ntawm kev sib koom ua ke lossis cuam tshuam qhov haum.
IV. Preheat lub Copper Tube
Siv cov khoom siv welding los preheat cov yeeb nkab tooj liab. Lub preheating kub nyob ntawm cov khoom siv vuam thiab cov specifications ntawm cov yeeb nkab tooj liab. Preheating ua rau lub vuam qhov sib npaug ntawm qhov sib npaug, txhim kho qhov zoo ntawm qhov sib koom ua ke thiab tso cai rau cov flux kom qhib.
V. Kev Ua Haujlwm
Siv cov flux rau qhov chaw huv thiab ntxig cov yeeb nkab rau hauv qhov haum. Siv cov nplaum rau ntawm lub qhov ncauj ntawm qhov haum thaum cua sov ntawm qhov sib koom ua ke, kom cov solder melts thiab yog kos tusyees rau hauv qhov sib txawv ntawm cov raj tooj liab los ntawm kev ua haujlwm capillary. Khaws qhov kub ntawm qhov vuam qhov tsis sib xws thaum lub sijhawm ua haujlwm, tsis txhob muaj cua sov los yog overcooling.
VI. Txias thiab tshuaj xyuas
Tom qab soldering tiav lawm, cia lub raj tooj liab kom txias lawm. Tshawb xyuas qhov zoo ntawm qhov chaw welded kom paub tseeb tias qhov sib koom ua ke ruaj khov tsis muaj qhov cua thiab tsis muaj kab nrib pleb. Yog tias tsim nyog, ua qhov kev ntsuas siab kom ntseeg tau tias tsis muaj qhov xau hauv cov yeeb nkab tooj liab. Ntxuav cov dej uas seem tshuav nrog ib daim ntaub ntub dej tom qab txias.
Cov lus nug nquag
Q: Vim li cas thiaj ntxuav cov yeeb nkab ua ntej soldering?
A: Oxides thiab av thaiv capillary ntws thiab ua rau cov leeg tsis muaj zog.
Q: Lub luag haujlwm ntawm flux yog dab tsi?
A: Flux tshem tawm oxides thiab txhawb kev sib koom ua ke.
Q: Yuav ua li cas solder kos rau hauv qhov sib koom?
A: Capillary kev txiav txim rub molten solder rau hauv qhov sib txawv ntawm lub raj thiab haum.
Q: Yuav tsum sib koom ua ke overheated?
A: Tsis yog, cov cua sov tsis sib xws tsis txhob ua rau cov flux thiab qhov sib koom ua ke.
Q: Ua li cas sib koom ua tau zoo xyuas?
A: Kev kuaj pom pom rau qhov khoob thiab tawg, ntxiv rau kev ntsuas siab.
Q: Thaum twg lub system tuaj yeem raug nias?
A: Tom qab qhov sib koom ua ke txias lawm thiab cov dej seem seem raug ntxuav.
