AWS E309MoL-16 sawv cev rau ib qho kev tshwj xeeb309mo electrodetsim los rau kev siv vuam hlau tsis xeb zoo. Lub electrode uas muaj cov pa roj carbon tsawg, titanium-calcium coated no muaj cov khoom sib xyaw ua ke ntawm Cr23Ni13Mo2 stainless hlau uas muab kev ua haujlwm vuam zoo thiab cov khoom siv kho tshuab. Kev faib tawm electrode 309mo qhia txog nws cov ntsiab lus tshwj xeeb thiab kev tsim nyog rau kev koom ua ke cov hlau sib txawv thiab kev sib tshooj cov hlau carbon nrog cov hlau tsis xeb. Nws cov ntsiab lus carbon tsawg heev txo cov carbide precipitation, ua kom ntseeg tau tias muaj kev tiv thaiv corrosion zoo dua hauv cov pob qij txha welded.
Lub electrode 309mo no zoo heev hauv cov txheej txheem vuam hluav taws xob arc, muab kev ua haujlwm du nrog kev tshem tawm yooj yim thiab tsawg kawg nkaus spatter. Lub titanium-calcium txheej muab cov yam ntxwv arc ruaj khov thiab zoo nkauj bead zoo, ua rau nws haum rau ob tus neeg welders tshiab thiab cov neeg paub dhau los. Lub electrode tswj cov khoom siv hlau sib xws thoob plaws ntau qhov chaw vuam, qhia txog kev hloov pauv zoo rau ntau qhov chaw ua haujlwm thiab cov kev xav tau ntawm qhov project. Nws cov khoom sib npaug ua kom ntseeg tau tias cov kua dej vuam hloov pauv thiab tswj cov yam ntxwv nkag mus.
Cov lus qhia txog kev siv tshuab ntawm lub tshuab vuam no ua rau nws muaj txiaj ntsig zoo rau kev koom ua ke cov hlau tsis xeb austenitic thiab rau kev sib tshooj cov khoom siv carbon steel. Cov ntsiab lus molybdenum hauv qhov no309mo electrodeua rau muaj kev tiv thaiv rau qhov xeb ntawm qhov pitting thiab crevice, ua rau nws tsim nyog rau kev siv hauv kev ua tshuaj lom neeg, cov khoom siv roj av, thiab kev lag luam tsim hluav taws xob. Cov hlau uas tau tso tawm muaj lub zog tensile siab thiab ductility zoo, tswj kev ua haujlwm zoo hauv qab thermal cycling thiab kev ntxhov siab.
Kev ruaj ntseg zoo yog tswj los ntawm kev ua raws li AWS E309MoL-16 cov qauv, kom ntseeg tau tias muaj kev ua tau zoo thiab kev ntseeg tau. Cov qauv ntawm lub electrode raug kuaj xyuas kom zoo rau cov tshuaj lom neeg, cov khoom siv kho tshuab, thiab cov yam ntxwv ntawm kev vuam. Txhua pawg yog tsim nyob rau hauv cov xwm txheej tswj hwm kom lav qhov tuab ntawm txheej sib npaug, kev kam rau siab ntawm txoj kab uas hla, thiab kev ruaj khov zoo tshaj plaws. Cov electrodes tau ntim khoom kom tiv thaiv kev nqus dej noo, uas lwm yam yuav cuam tshuam rau kev ua haujlwm vuam thiab qhov zoo ntawm kev vuam.
Tnws cov nqi them ua ntej309mo electrodemuab kev daws teeb meem zoo rau cov kws tshaj lij vuam hlau rau cov ntawv thov tseem ceeb ntawm cov hlau tsis xeb. Nws ua ke ntawm cov qauv qis-carbon, kev txhim kho molybdenum, thiab cov yam ntxwv vuam yooj yim rau tus neeg siv ua rau nws yog qhov kev xaiv zoo rau kev kho thiab kev tsim khoom tshiab. Lub electrode muab cov txiaj ntsig zoo sib xws thaum ua tau raws li cov kev cai nruj ntawm cov qauv vuam niaj hnub.
