Ob qho laj thawj vim li cas lub taub hau hlau tsis noj tin
1. Pheej yig sab hauv cua sov uas tsis muaj zog hluav taws xob soldering hlau
Lub taub hau ntawm lub tshuab hluav taws xob hluav taws xob 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 electrified rau ib lub sij hawm ntawm lub sij hawm, qhov kub ntawm lub soldering hlau taub hau yuav siab dua thiab siab dua, thiab nyob rau hauv high kub, tooj liab soldering hlau taub hau yog nquag oxidation thiab blackening. Ntawd yog, yog tias lub taub hau hlau yog polished nrog cov ntawv xuab zeb lossis cov ntaub ntawv, nws tseem yuav oxidize thiab blacken tom qab lub sijhawm luv luv.
Yog hais tias nws yog tiag tiag siv cov pheej yig hluav taws xob soldering hlau uas ua rau oxidation thiab blackening ntawm lub taub hau soldering hlau thiab tsis noj tin, nws yog pom zoo kom hloov cov hluav taws xob soldering hlau, nyiam dua siv ib tug tas li kub soldering hlau los yog adjustable kub soldering hlau. . Piv txwv li, lub taub hau ntawm 936 adjustable kub hluav taws xob soldering hlau tuaj yeem hloov tau, muaj ntau yam duab uas tuaj yeem xaiv raws li qhov xav tau vuam. Lub taub hau soldering no yog ua los ntawm cov khoom siv hlau, uas tsis yooj yim rau oxidized ntawm qhov kub thiab txias. Tsuav yog lub taub hau soldering tsis corroded los ntawm acid flux thiab tsis siv lub taub hau soldering kub kub-melt nplaum nplaum thiab yas, nws yog ib qho yooj yim mus tin lub taub hau soldering.
2. Siv cov kua qaub los yog cov hlau nplaum uas muaj cov impurities ntau dhau
Ntau tus novice welders nyiam siv cov kua qaub kua nplaum ua kua nplaum thaum vuam. Cov flux no yog me ntsis acidic thiab tuaj yeem corrode qee cov lus qhia zoo soldering hlau.
Nws raug nquahu kom siv blocky rosin lossis rosin cawv daws raws li cov dej ntws hauv lub sijhawm vuam.
Tsis tas li ntawd, pheej yig soldering hlau muaj ntau cov impurities, thiab siv cov hlau soldering no tuaj yeem ua rau lub taub hau hlau tsis noj cov tin.
Hom solder hlau no tsis zoo wettability thiab fluidity tom qab melting, thiab solder pob qij txha yog tsaus, tsis du thiab ci. Yog hais tias qhov tsis zoo ntawm cov hlau soldering ua rau lub taub hau ntawm lub taub hau kom tsis txhob noj cov tin, nws raug nquahu kom siv cov khoom siv hluav taws xob uas tsis tshua muaj melting qhov chaw vuam hlau thaum lub sij hawm vuam.
