Kev vuam hlau tsis xeb yog ib feem tshwj xeeb ntawm kev sib koom ua ke hlau uas xav tau kev tswj hwm meej ntawm cov khoom siv hlau thiab cov txheej txheem txheej txheem. Kev xaiv cov ntaub ntawv sau kom haum yog qhov tseem ceeb rau kev ua tiav cov yam ntxwv xav tau hauv kev vuam, tshwj xeeb tshaj yog thaum ua haujlwm nrog cov hlau kub thiab cov hlau tsis xeb. Hauv qhov kev tshaj lij no, AWS A5.4 E310-16 kev faib tawm xaiv ib hom hlau tsis xeb hlau vuam electrode tsim rau cov ntawv thov nyuaj uas qhov kev ua haujlwm kub siab yog qhov tseem ceeb.
Lub E310-16 electrode, uas tau muab lub npe lag luam hu ua A402, muaj cov khoom siv austenitic Cr26Ni21 uas muaj cov txheej txheem titania-calcium. Cov txheej txheem flux no ua rau muaj kev ua haujlwm ntau yam nrog ob qho tib si alternating thiab direct current power sources, thaum muab kev ruaj khov arc zoo heev thiab kev tshem tawm slag uas ua rau tus neeg teb xov tooj siv tau zoo dua. Cov mis sib npaug txhawb kev hloov pauv hlau du, tsawg kawg nkaus spatter generation, thiab yooj yim tshem tawm slag.—cov yam ntxwv uas ua ke pab txhawb rau kev txhim kho qhov zoo thiab kev ua haujlwm ntawm weldvuam hlau tsis xebcov txheej txheem.
Ib qho yam ntxwv ntawm lub electrode no yog qhov tshwj xeeb kub siab oxidation tsis kam uas pom los ntawm nws cov hlau tso, uas tswj kev ncaj ncees ntawm cov qauv hauv 900°C txog 1100°C ntau yam. Qhov kev ua tau zoo no ua rau nws tsim nyog rau kev tsim cov khoom uas raug cua sov tas mus li, cov khoom siv hauv qhov cub, cov khoom siv kho cua sov, thiab cov txheej txheem ua haujlwm kub siab. Lub austenitic microstructure ntawm cov hlau vuam muab ob qho tib si thermal stability thiab ductility, tiv thaiv cov xwm txheej embrittlement uas yuav ua rau lub neej kev pabcuam ntawm cov khoom puas tsuaj.
Hais txog qhov scope ntawm daim ntawv thov, qhov novuam hlau tsis xebLub electrode qhia tau tias nws muaj peev xwm ua tau ntau yam tshaj li nws txoj haujlwm tseem ceeb ntawm kev koom ua ke cov hlau tsis xeb uas tiv taus cua sov zoo sib xws. Nws ua haujlwm tau zoo rau kev vuam cov hlau chromium uas tau quenched suav nrog Cr5Mo, Cr9Mo, Cr13, thiab Cr28 qib, thaum tseem muab cov kev daws teeb meem txhim khu kev qha rau cov hlau sib txawv ntawm cov khoom siv austenitic thiab ferritic. Qhov kev sib raug zoo hla qib no txo cov kev xav tau khoom muag thaum tswj hwm qhov zoo ntawm kev vuam thoob plaws ntau yam kev kho thiab kev tsim khoom.
Kev faib tawm E310-16 sawv cev rau kev daws teeb meem siab heev hauvvuam hlau tsis xebthaj chaw, tsim tshwj xeeb rau qhov chaw kub thiab txias heev. Nws txoj kev sib xyaw ua ke ntawm cov yam ntxwv ua haujlwm, cov khoom siv hlau, thiab kev ywj pheej ntawm daim ntawv thov ua rau lub electrode no yog ib qho khoom muaj nqis rau cov lag luam uas xav tau kev ua haujlwm zoo hauv qab kev kub ntxhov. Qhov tseem ceeb ntawm cov khoom siv tshwj xeeb no qhia txog qhov tseem ceeb ntawm cov txheej txheem tshwj xeeb ntawm cov khoom siv hauv cov ntawv thov vuam hlau stainless.
