Cov kauj ruam ntawm lub taub hau ntawm cov hluav taws xob soldering hlau noj tin, 2 yog vim li cas vim li cas cov hlau taub hau tsis noj tin
1. Sib tsoo lossis so
Lub taub hau zoo tib yam: thawj zaug siv cov ntawv xuab zeb los zom lossis ua ntaub ntawv, qhov ntev ntawm kev sib tsoo yog me ntsis ntev dua qhov siab ntawm txoj kab nqes, ceev faj kom txog thaum lub dav hlau huv thiab du. Tom qab ntawd so nrog ib daim ntaub huv, qhuav.
Lub taub hau ntev: Tsis txhob xuab zeb los yog ntaub ntawv, tsuas yog so nrog ib daim ntaub huv, qhuav.
2. Noj tin
Npaj ib lub thawv me me ntawm rosin (txawm tias cov hlau nplaum muaj cov rosin, tab sis cov nyiaj tsawg dhau, nws tsis yooj yim rau noj tin), txuas lub hwj chim ntsaws, tos ib pliag, lub hau ntawm cov hlau yuav kub, siv lub taub hau ntawm cov hlau nplaum los kov cov rosin los kwv yees qhov kub thiab txias. Yog tias cov rosin tuaj yeem tsuas yog yaj, nws txhais tau tias qhov kub thiab txias tseem qis; Yog hais tias lub rosin tso pa taws dawb thiab cov plaub hau hlau yog xim liab, nws txhais tau hais tias qhov kub thiab txias heev; tsuas yog thaum rosin tuaj yeem yaj sai sai thiab tsis haus luam yeeb ntau, qhov kub thiab txias yog qhov zoo tshaj plaws.
Thaum qhov kub ntawm cov hlau taub hau mus txog qhov zoo tshaj plaws, sib npaug ntawm cov hlau taub hau nrog rosin.
Lub soldering hlau dipped nyob rau hauv rosin yuav tsum sai sai yaj lub solder hlau nyob rau hauv lub soldering hlau thav duab kom nws ib tug loj solder point (ntxiv me ntsis rosin), thiab lub soldering hlau taub yog immersed thiab tig dua mus txog rau thaum lub polished ib feem ntawm lub soldering hlau taub. yog tusyees noj tin.
3. Kev laus:
Tom qab lub soldering hlau taub noj tin, hnub nyoog lub soldering hlau.
Kev laus tsis yog siv cov hlau soldering rau ib ntus, cia nws txuas ntxiv kom muaj zog thiab ua kom sov rau ib ntus, tom qab ntawd tshem tawm cov hlua hluav taws xob, thiab muab tso rau ntawm cov hlau txuas kom cia nws txias lawm.
Kev laus tuaj yeem ua rau lub neej ntev ntawm cov lus qhia thiab cov cores, tshwj xeeb tshaj yog rau cov lus qhia tshiab thiab cov cores. Tom qab noj cov tin thiab cov laus soldering hlau, nws tuaj yeem siv tau ib txwm nyob rau yav tom ntej.
Yog hais tias nws yog ib tug hluav taws xob soldering hlau nyob rau hauv ib txwm siv, ua ntej ib tug tshiab puag ncig energized vuam, nws yog tsim nyog los xyuas seb lub soldering hlau taub yog "hlawv" los yog "chaw nres nkoj tsis tiav".
"Hlawv kom tuag" txhais tau hais tias cov tin noj ib feem ntawm cov hlau taub hau tau oxidized thiab tig mus rau hauv lub taub hau dub, tsis dipped nyob rau hauv tin, los yog lub peev xwm mus poob rau hauv tin yog heev tsis zoo; "chaw nres nkoj tsis tiav" txhais tau hais tias qhov chaw ua haujlwm yog deformed lossis tawg. Ob qho xwm txheej no yuav tsum tau rov tinning lub ntsis ntawm cov hlau soldering.
Ob qho laj thawj vim li cas lub taub hau hlau tsis noj tin

Yog hais tias nws yog ib tug hluav taws xob soldering hlau nyob rau hauv ib txwm siv, ua ntej ib tug tshiab puag ncig energized vuam, nws yog tsim nyog los xyuas seb lub soldering hlau taub yog "hlawv" los yog "chaw nres nkoj tsis tiav".
"Hlawv kom tuag" txhais tau hais tias cov tin noj ib feem ntawm cov hlau taub hau tau oxidized thiab tig mus rau hauv lub taub hau dub, tsis dipped nyob rau hauv tin, los yog lub peev xwm mus poob rau hauv tin yog heev tsis zoo; "chaw nres nkoj tsis tiav" txhais tau hais tias qhov chaw ua haujlwm yog deformed lossis tawg. Ob qho xwm txheej no yuav tsum tau rov tinning lub ntsis ntawm cov hlau soldering.
Ob qho laj thawj vim li cas lub taub hau hlau tsis noj tin
1. Pheej yig sab hauv cov cua sov hom uas tsis muaj hluav taws xob hluav taws xob soldering hlau
Lub taub hau ntawm lub taub hau ntawm cov cua sov sab hauv no yog ua los ntawm tooj liab, tsis muaj qhov kub thiab txias, thiab tsis tuaj yeem hloov kho.
Tom qab no hom hluav taws xob soldering hlau yog energized rau ib lub sij hawm ntawm lub sij hawm, qhov kub ntawm lub soldering hlau taub yuav siab dua thiab siab dua, thiab cov tooj liab soldering hlau taub yog yooj yim rau oxidize thiab blacken nyob rau hauv high kub. Txawm hais tias lub taub hau hlau yog polished nrog cov ntawv xuab zeb lossis cov ntaub ntawv, nws tseem yuav oxidize thiab tig dub tom qab lub sijhawm luv luv.
Yog tias nws yog qhov tseeb ntawm kev siv cov khoom siv hluav taws xob pheej yig uas ua rau lub taub hau ntawm lub taub hau rau oxidize thiab blacken thiab tsis noj tin, nws raug nquahu kom hloov cov hlau soldering. Nws yog qhov zoo tshaj plaws los siv qhov kub thiab txias tsis tu ncua ntawm soldering hlau los yog adjustable kub soldering hlau. Piv txwv li, qhov ntxeev ntawm 936 adjustable kub hluav taws xob soldering hlau tuaj yeem hloov tau, thiab muaj ntau cov duab, uas tuaj yeem xaiv raws li qhov xav tau ntawm vuam. Qhov zoo ntawm cov hlau taub hau no yog ua los ntawm cov khoom siv hlau, uas tsis yooj yim rau oxidize ntawm qhov kub thiab txias. Ntev npaum li lub taub hau hlau tsis corroded los ntawm cov kua qaub, thiab cov taub hau hlau tsis yog siv los scald kub yaj kua nplaum los yog yas, lub taub hau hlau yog yooj yim rau tin.
2. Siv cov kua qaub los yog cov xaim hlau uas muaj cov impurities ntau dhau
Ntau tus novice welders nyiam siv acidic solder paste li flux thaum vuam. Qhov no flux yog me ntsis acidic thiab yuav corrosive rau ib co inferior soldering hlau tswv yim.
Nws raug nquahu kom siv cov block rosin lossis rosin cawv ua kua dej thaum soldering.
Tsis tas li ntawd, pheej yig solder hlau muaj ntau impurities, thiab kev siv ntawm no solder hlau kuj yuav ua rau lub ntsis ntawm lub soldering hlau tsis noj tin.
Qhov zoo ntawm cov hlau no muaj cov dej tsis zoo thiab cov dej ntws tom qab yaj, thiab cov pob qij txha yog tsaus, tsis du thiab ci ntsa iab. Yog hais tias qhov zoo ntawm cov hlau hlau tsis zoo thiab cov ntsiab lus ntawm cov hlau tsis noj cov tin, nws raug nquahu kom siv cov khoom zoo uas tsis tshua muaj melting point solder hlau thaum soldering.
