Cov khoom lag luam
Cored hlau yog ib hom flux-cored vuam hlau uas siv rau ntau yam kev siv hauv kev lag luam vuam. Nws yog ib txoj kev yooj yim thiab ua tau zoo los qhia cov alloys ntxiv thiab cov ntsiab lus rau hauv weld yam tsis muaj kev xav tau cais vuam vuam lossis khoom siv. Cored hlau yog siv nyob rau hauv cov kab hlau sib xyaw, nkoj nkoj, tsheb tsim khoom, thiab lwm yam khoom siv uas muaj txiaj ntsig zoo. Ib qho ntawm qhov zoo ntawm cov xaim xaim yog nws lub peev xwm los ua cov welds muaj zog, ntxuav cov ntaub ntawv so nrog minimal cais thiab nti. Nws tseem muab tau cov nqi nkag siab zoo thiab cov nqi depigition, ua rau nws zoo tagnrho rau ntau txoj haujlwm vuam. Ib qho ntxiv, xaim hlau yooj yim siv thiab tsim nyog rau ob txhais phau ntawv thiab siv cov txheej txheem vuam. Nrog kev cob qhia tsim nyog thiab tuav, cored hlau muaj peev xwm txhim kho vuam welding ua hauj lwm thiab khoom lag luam. Zuag qhia tag nrho, cored hlau yog ib qho kev xaiv ntau yam thiab txhim khu kev qha rau kev ua tiav cov khoom siv zoo hauv ntau cov ntawv thov.
