Cov lus nug ntawm yuav ua li cas solder tsis yog rau cov kws tsim khoom hauv tsev niaj hnub thiab cov techies niaj hnub no. Tab sis thaum nws los txog rau nws, nws hloov tawm zoo li hauv cov lus tso dag hais txog Leo Tolstoy, uas nyiam ua si balalaika, tab sis, hmoov tsis, ua tsis tau.
Vim cov kws txawj ua txuj ci ua cov hlau lead thiab cov tin, muaj cov tinkers uas muab cov hlau blanks.
Txuas ua ntej soldering ntxuav thiab degreased nrog roj av. Lub taub hau ntawm cov hlau uas muaj cua sov yog dipped hauv rosin lossis ammonia. Yog tias muaj pa taws faus tshwm, ces cov hlau nplaum tau npaj ua haujlwm.
Rosin ntxuav lub taub hau ntawm cov hlau oxides. Lub taub ntxuav ntawm cov hlau soldering yog dipped nyob rau hauv solder (feem ntau yog tin) thiab tuav nyob rau ntawd kom txog thaum nws yog them nrog ib zaj duab xis. Qhov no zaj duab xis yog leveled tshaj saum npoo ntawm kev sib koom tes, i.e. "tinker" nws. Tom qab ntawd qhov ntau ntawm cov solder raug xa mus rau qhov sib txuas, uas yog qhov tsim nyog los txuas cov workpieces.
Thiab yuav ua li cas thiaj tsis siv hlau? Koj tuaj yeem siv cov tshuaj sib xyaw ua ke uas tuaj yeem tso tawm "solder" thaum lawv qhov kub thiab txias. Cov no yog solder pastes. Lawv yog indispensable rau soldering nyob rau hauv ib tug nyuaj mus cuag qhov chaw. Cov tshuaj nplaum yog siv rau kev sib tshuam thiabsov so.
Tam sim no cia peb saib yuav ua li cas solder aluminium. Qhov no tsis yog ib qho yooj yim ua, txij li thaum lub aluminium nto yog ntxuav, ib tug oxide zaj duab xis yog tsim dua. Lub xub ntiag ntawm xws li ib zaj duab xis txo lub zog ntawm kev sib txuas. Yog li ntawd, tam sim ntawd tom qab ntxuav qhov saum npoo ntawm qhov sib koom ua ke, ib qho passive flux yog poured rau hauv txhuas dawb paug. Nws tuaj yeem yog rosin, glycerin thiab ib qho ntawm cov fatty acids.
Soldering ntawm txhuas yog ua nrog ib tug muaj zog soldering hlau. Yog tias qhov flux raug xaiv raug, ces aluminium yog yooj yim soldered. Copper hlau tuaj yeem soldered rau nws tinned nto yam tsis muaj teeb meem.
Tseem muaj lwm txoj hauv kev: txheej txheej ntawm aluminium ntawv ci yog ntxuav, smeared nrog rosin, sprinkled nrog tooj liab hmoov. Tom qab ua haujlwm no, cov khoom tuaj yeem raug soldered nrog cov tin solder.
Tsis ntev tas los no, cov kav hlau hlau tau hloov los ntawm cov khoom yas. Yuav ua li cas solder yas kav? Qhov no tsis yog qhov nyuaj ua yog tias koj muaj cov cuab yeej tsim nyog rau vuam lawv.
Nozzles ntawm qhov ntau thiab tsawg yog txuas rau lub tshuab cua sov. Tus tswj ntsuas kub tsis siab tshaj 2700 Celsius.
Thaum lub nozzles ntawm lub tshuab vuam yog cua sov, cov kav dej ntawm qhov ntev yuav tsum tau npaj thiab txiav. Burrs thiab irregularities yuav tsum tau muab tshem tawm, ces ib tug cim sib npaug zos rau qhov tob ntawm lub haum yog muab tso rau hauv cov yeeb nkab. Tom qab cua sov, cov yeeb nkab yuav nkag mus rau qhov haum rau qhov ntev koj ntsuas. Qhov chaw yuav tsum tau welded yog degreased. Tam sim no nws yog lub sij hawm kom sov thiab solder.
Ntawm lub rhuab nozzle nyob rau ntawm ib sabwelding tshuab, qhov haum yog thawj zaug muab tso rau, vim nws muaj cov phab ntsa tuab, thiab qhov no yuav tsum tau siv cua sov ntev. Lub fitting yuav tsum nruj nreem zaum ntawm lub nozzle. Nyob rau sab nraud ntawm lub tshuab vuam, ib lub yeeb nkab yas "tso" ntawm lub nozzle thib ob.
Lub sijhawm cua sov ntawm cov yeeb nkab thiab kev sib dhos yog qhia hauv cov lus qhia rau lub tshuab vuam. Thaum cua sov cov khoom yuav tsum tau koom nrog, sim tsis txhob tig lawv, vim qhov no yuav ua rau cov yas ntim.
Lub sijhawm cua sov yog khaws cia, tom qab ntawd cov khoom raug tshem tawm ntawm lub nozzles, thiab cov yeeb nkab maj mam muab tso rau hauv qhov haum rau cov cim ua ntej. Nws yog tsis yooj yim sua rau twist qhov txuas.
Tam sim no koj paub yuav ua li cas rau cov kav dej yas.
