1. Dab tsi yog flux cored vuam hlau?
Ib hom welding hlau ua los ntawm dov ib tug nyias steel sawb rau hauv ib puag ncig steel raj thiab ib txhij sau nws nrog ib tug npaum li cas ntawm cov hmoov tshuaj.
2. Vim li cas cov flux cored vuam hlau tiv thaiv nrog CO2 roj?
Muaj ob hom flux-cored welding hlau nyob rau hauv cov nqe lus ntawm kev tiv thaiv: cov tub ntxhais roj shielded vuam hlau thiab cov tshuaj core tus kheej tiv thaiv vuam hlau. Cov tub ntxhais roj shielded vuam hlau feem ntau muaj kev tiv thaiv los ntawm CO2 roj, uas belongs rau cov ntaub ntawv sib xyaw roj thiab kev tiv thaiv slag. Lub weld tsim tau zoo thiab tag nrho cov tshuab ua haujlwm siab.
3. Vim li cas qhov flux-cored weld qhov muaj qhov indentation blowhole?
Vim hais tias cov xaim flux-cored yog ib tug tubular hlau qhov txhab los ntawm ib tug nyias steel sawb, nws belongs rau ib tug seamed hlau. Cov dej noo hauv huab cua tuaj yeem cuam tshuam cov tub ntxhais los ntawm qhov sib txawv, thiab cov dej ntws ntub dej (tsis tuaj yeem qhuav), ua rau muaj qhov pores hauv qhov sib txuas.
4. Vim li cas thiaj muaj cov kev cai rau kev purity ntawm CO2 roj?
General CO2 roj yog cov khoom siv los ntawm kev tsim tshuaj lom neeg. Nws purity tsuas yog hais txog 99.6%. Nws muaj cov kab ntau ntawm impurities thiab dej, uas tuaj yeem ua rau muaj qhov tsis xws li porosity hauv welds. Kev vuam ntawm cov khoom tseem ceeb yuav tsum siv CO2 purityNtau dua lossis sib npaug99.8% roj, vuam porosity yog me me, tsis tshua muaj hydrogen cov ntsiab lus, tawg kuj zoo.
5. Vim li cas thiaj li muaj kev xav tau siab rau argon purity?
Tam sim no, muaj peb hom argon nyob rau hauv kev ua lag luam: dav argon (li 99.6% ntshiab), ntshiab argon (li 99.9% ntshiab), high-purity argon (purity 99.99%), thawj ob hom weldable carbon steel thiab stainless. steel, thiab welded aluminium. Cov hlau tsis-ferrous xws li txhuas alloys, titanium, thiab titanium alloys yuav tsum tau ua los ntawm high-purity argon; cov welds thiab tshav kub-tshem tawm tsam yuav tsum tsis txhob oxidized kom welded.
