1.What yog qhov tseem ceeb rau cov txheej txheem hlawv?
Thaum lub sij hawm vuam, arc kub kub, molten pas dej sov los yog nplaim taws (xws li kub vuam) yog tsim tawm, thiab qhov kub hauv zos tuaj yeem mus txog ntau txhiab tus neeg. Yog tias cov txheej yog ncaj qha rau hauv thaj chaw kub, lossis cua sov kom muaj kev puas tsuaj, nws yuav ua rau nws npau taws lossis poob, uas yog hu ua "hlawv".
2. Kev sib txawv hauv cov cua sov ua rau muaj kev cuam tshuam sib txawv ntawm cov txheej txheem sib txawv cuam tshuam dab tsi cuam tshuam?
Tsawg-kub txheej txheem (xws li feem ntau cov txheej txheem organic, yas tsho loj, thiab hluav taws xob xim): qhov tiv taus hluav taws xob feem ntau yog qis dua 200 degree. Txawm hais tias nws yog kev ua haujlwm tsis ncaj ncees thaum lub sij hawm vuam, nws yog qhov yooj yim rau discolor, npuas, lossis carbonize.
Nruab nruab nrab kub lub taub hau (xws li qee cov xim xim nplua nuj thiab cov xim kub ua kom sov thiab cua sov resistant): nws tuaj yeem tiv taus txog 200-400 degree. Lub sijhawm luv luv sib chwv nrog vuam cov ntawv tso dej thaum tshav kub kub yuav ua rau muaj kev puas me ntsis, tab sis chees ncaj qha nrog Arc yuav hlawv nws.
Kev kub siab pib (xws li Ceramic Txheej Txheem, Kub Kub Tiv Thaiv, thiab ua kom muaj kev tiv thaiv hlau kom ntev li 500 thiab tuaj yeem tiv thaiv kev siv laser vuam lossis brazing) raws li kev tiv thaiv zoo.
3.Yog dab tsi ua cov txheej txheem vuam thiab cua sov muaj ntau ntawm cov txheej txheej?
Arc vuam (xws li arc vuam, Argon arc vuam): lub arc kub yog qhov siab heev (3000 degree), thiab tshav kub yog feeb. Yog tias txheej yog ze rau Weld (xws li nyob rau hauv Weld (xws li nyob rau hauv 10mm), nws yog yooj yim heev rau kev tawg ncaj qha lossis puas los ntawm tshav kub ntawm lub substrate.
Roj Vuam / Roj Txiav: Lub nplaim taws yog li 3000 degree, lub tshav kub sib piv ntau yog loj, thiab txheej txheej kev puas tsuaj yuav dav.
Laser Vuam: Cov cua sov yog lub sijhawm thiab lub sijhawm txiav txim luv. Yog tias cov tsis muaj zog tau tswj hwm (xws li lub zog qis, ntsuas cua nrawm), cov cua sov-cuam tshuam rau cov txheej me me, thiab tsuas yog ntug yuav yog qhov puas me ntsis.
Kuj vuam (xws li chaw vuam): Cov cua sov yog feeb los ntawm qhov chaw vuam. Yog tias ib puag ncig cov txheej nyob deb (xws li ntau tshaj 5 hli), nws tsuas yog hloov pauv xim vim kev tuaj yeem kub, ntau dua li ua kom tawg tag lawm.
4.Qhov kev txheeb ze txoj hauj lwm ntawm txheej txheem rau kev siv Weld cuam tshuam rau seb cov txheej yog hlawv?
Cov txheej hauv Weld Cheeb Tsam: Yog tias cov txheej muaj txheej txheem, cov txheej txheem impurities thiab ua kom muaj kev cuam tshuam ncaj qha los ntawm kev ua haujlwm hauv Weld feem ntau yuav tsum tau muab tshem tawm ua ntej vuam.
Txheej ze ntawm lub weld: qhov ze rau qhov deb (xws li<5mm), the greater the impact of heat conduction, especially the thin substrate (such as sheet metal) with fast heat conduction, the coating is more easily damaged; when the distance is far (such as >10 hli), tej zaum yuav muaj kev sib deev me me xwb.
5.Qhov yog cov kev ntsuas kom tsis txhob txheej txheem hlawv?
Ua ntej vuam, tshem tawm cov txheej ntawm weld thiab thaj chaw ze (tsawg kawg 5-10 hli).
Xaiv cov qauv vuam nrog cov cheeb tsam muaj cua sov thiab thaj av me me (xws li laser vuam, ntshav arc vuam).
Kev tswj cov khoom lag luam vuam (txo qhov tam sim no, nce qhov ceev) los txo cov tswv yim sov.
Noj cua txias (xws li cov dej txias) lossis rwb thaiv tsev kom sov (xws li cov pab pawg asbestos tiv thaiv) kev ntsuas rau thaj chaw txheej.
Yog tias cov txheej yuav tsum tau khaws cia, vuam yuav ua thawj zaug thiab tom qab ntawd txheej (siv rau scenarios qhov twg tom qab txheej yog tso cai).
