tooj liab stripmuaj hluav taws xob zoo thiab thermal conductivity, tab sis tseem muaj ntau yam teeb meem nyuaj hauv cov txheej txheem vuam.Lub thermal conductivity ntawm liab tooj liab siv yog ntau dua li cov hlau.Vuam cov cua sov feem ntau yuav ploj, feem ntau yuav ua rau muaj kev ntxhov siab ntau dhau, ua rau vuam deformation thiab lwm yam teeb meem vuam.Yog li ntawd, thaum tshav kub kub concentration yuav tsum tau thaum vuam.Vuam txoj kev muaj xws li tungsten argon arc vuam thiab plasma vuam.Tsis tas li ntawd, qhov tsim nyog preheating yuav tsum tau nqa tawm ua ntej vuam.Ib qho me me ntawm brazing yuav tsum tsis txhob preheated yog tias nws tsis tsawg tshaj li xoom.
Txawm li cas los xij, tsis hais txog hom tooj liab, cov txheej txheem vuam yuav tsim cov pa taws dawb, txhais tau hais tias txawm tias zinc tsis yog cov hlau hnyav, yog tias qhov chaw vuam tsis zoo, cov pa luam yeeb dawb tuaj yeem ua rau lub ntsws ua pa, tshwj xeeb tshaj yog lub ntsws, lossis yog tias tus neeg ua haujlwm tsis hnav lub npog ntsej muag, tom qab 30 feeb ua haujlwm, lawv yuav poob.Liab tooj liab daim kab xev yog cov khoom siv vuam, cov khoom siv yuav tsum yog tib yam li cov khoom siv hauv paus.Rau cov vuam zoo tib yam nkaus xwb, φ2.5-φ4 zoo tib yam tooj liab alloy hlau tuaj yeem siv tau.
Cov kua deg nro coefficient ntawm tooj liab sawb tsuas yog 70% ntawm cov hlau.Nws yog ib qho yooj yim ua rau lub pas dej molten yob nyob rau hauv cov txheej txheem vuam, thiab cov hauv paus hniav yuav tsis yaj.Txhawm rau daws qhov teeb meem no, koj yuav tsum pib nrog tib txoj kev vuam thiab tom qab ntawd ua tiav.Thaum pib vuam, lub vuam lub kaum sab xis (10 ° -30 °) tsis haum, tab sis tsuas yog lub kaum sab xis no tuaj yeem daws qhov teeb meem melting ntawm tungsten argon arc vuam.
Yog tias koj xav tau cov khoom siv vuam zoo, tsis txhob ntshai tus nqi kim, nws raug nquahu kom siv cov roj inert heev tiv thaiv flux cored hlau, vuam yuav ua haujlwm zoo, tab sis tus nqi siab heev, thiab TIG vuam nws tus kheej tsis pheej yig.Nyob rau hauv luv luv, tooj liab sawb busbar vuam yog kub kub, lub kaum sab xis me me thiab kev tiv thaiv siab ua haujlwm.
