Q: Los ntawm kev pom ntawm cov txheej txheem kev ua kom zoo dua, yuav ua li cas txhim kho cov vuam kev ua tau zoo ntawm galvanized steel ntawv?
A: nce tshav kub ntxiv: siv cov vuam loj dua (10% {1% siab dua li grant (suav nrog kom txo weld porosity {2 2}}
Tswj lub voj voog thermal: zam kev kub lub sijhawm nyob ntev dhau los (xws li nias tus memiding) {}}}}}
Q: Dab tsi yog qhov ntsuas tseem ceeb los txhim kho kev ua haujlwm vuam kev ua tau zoo ntawm Galvanized steel ntawv?
A: Pretreatment ntawm Txheej
NEEG KHO TSHUAB SIB TSOO: Ua ntej Vuam, siv cov kav dej hlau los ntawm cov txheej txheem Mold (Alumining)
Tshuaj Tu: Siv cov tshuaj acid tsis muaj zog (xws li 5% dolochloric acid) los ntxuav cov yeeb yaj kiab oxide (al₂o₃), thiab txhim kho vuam wettability .
Q: Yuav ua li cas txhawm rau txhim kho cov vuam kev ua tau zoo ntawm galvanized steel ntawv los ntawm kev xaiv cov khoom siv vuam?
A: Vuam hlau xaiv: vuam hlau muaj silicon (si) lossis magnesium tuaj yeem ua kom zoo nkauj ntawm welmidation thiab txhim kho cov roj weld thiab txhim kho kev ua si ob sab. {}
Flux / Shielding roj: Siv cov roj (xws li 80%+20} lossis siv cov ntaub qhwv flux (xws li fluoride flux) kom nqus tau zoo aluminium .
Q: Yuav muaj kev ua haujlwm cuam tshuam rau kev ua haujlwm vuam?
A: Lub kaum thiab txoj kev: lub vuam rab phom yog qaij rov qab {}}}}}} degree} degree, thiab txo cov pores .
ARC Kev pib thiab ARC txiav: Siv daim ntawv hla ntawm Wello kom tsis txhob tshwm sim los ntawm kev kub hnyiab ntawm lub arc pib .
Multi-PAST VUAM TSWJ: Thaum vuam tuab daim hlau, siv cov txheej txheem nqaim, thiab tswj hwm tus interlayer kub hauv qab no 150 qib kom tsis txhob muaj qhov kub ntawm cov txheej kub ntawm txheej.
Q: Dab tsi yuav ua tom qab vuam?
A: Kev Tu Dua Tshiab: Siv tus kaw tooj liab los yog cov scraper tshwj xeeb kom tsis txhob muaj kev sib tw ntawm Weld los ntawm cov seem zinc thiab txhuas oxides .
Kev kho corrosion corrosion: siv zinc-nplua nuj xim (zinc cov ntsiab lus ntau dua los yog sib npaug ntawm lub vuam los tiv thaiv kev tiv thaiv corrosion {}}
Passivation kev kho mob: Txau lub thwj tim lossis inorganic silane passivation kua los mus ncua oxidation ntawm txheej ncig weld .
