Braze welding tsis xav tau capillary nkaus los rub cov hlau rau hauv qhov sib koom ua ke. Capillary action yog xav tau rau brazing. Cov pob qij txha tau sib cais yog qhov sib nrug los ntawm qhov me me uas tso cai rau kev txiav txim siab capillary los kos cov hlau muab tub lim rau hauv kev sib koom ua ke thaum cov khoom ncav cuag qhov kub thiab txias.
txheej txheem brazing yog dab tsi?
Brazing yog txheej txheem hlau-sib koom ua ke uas ob lossis ntau dua cov khoom hlau tau koom ua ke los ntawm melting thiab ntws cov hlau muab tub lim rau hauv kev sib koom ua ke, nrog cov hlau muab tub lim muaj qis dua. melting point tshaj cov hlau uas nyob ib sab.
4 theem ntawm brazing yog dab tsi?

Vim li cas flux siv hauv brazing?
Tus neeg sawv cev fluxing (lossis qhov chaw tswj tau raws li pom nyob rau hauv qhov cub brazing) yog xav tau rau txhua daim ntawv thov kev sib tsoo thiab cov khoom siv. Lub hom phiaj ntawm cov flux yog kom tshem tawm cov oxides los ntawm cov khoom siv hauv paus thiab tiv thaiv oxidation thaum lub sij hawm cua sov, yog li txhawb kev ywj pheej ntawm cov khoom siv hlau brazing.
Lub hom phiaj ntawm kev brazing yog dab tsi?
Ib yam zoo rau kev koom nrog cov hlau tsis sib xws, brazing yog cov txheej txheem kev lag luam uas tau siv nyob rau hauv ntau qhov kev lag luam vim nws qhov yooj yim thiab kev ntseeg siab uas cov pob qij txha yuav raug tsim. Qhov no ua rau nws txhim khu kev qha hauv cov ntawv thov tseem ceeb thiab tsis tseem ceeb, thiab nws yog ib qho ntawm cov kev sib koom ua ke ntau tshaj plaws.
