Polumikiza chitsulo chosapanga dzimbiri, kusankha ma electrode ndikofunikira kwambiri kuti pakhale cholumikizira chapamwamba komanso cholimba. Apa ndi pomweAF2209-15 (AWS E2209-15)imabwera. Electrode yachitsulo chosapanga dzimbiri yokhala ndi nayitrogeni yochepa kwambiri iyi yapangidwa kuti ikwaniritse zofunikira kwambiri pakuwotcherera. Ndi utoto wake wotsika wa hydrogen, AF2209-15 imatsimikizira kuti kuwotcherera kuli bwino komanso kugwira ntchito bwino.
AF2209-15 yapangidwa kuti igwiritsidwe ntchito polumikiza zitsulo zosapanga dzimbiri ziwiri ndipo imapereka kukana dzimbiri komanso mphamvu zambiri. Kuchuluka kwa kaboni komwe kali nako kumachepetsa chiopsezo cha mvula ya carbide, kuonetsetsa kuti makinawo ali ndi mphamvu zabwino kwambiri komanso kusinthasintha. Kuchuluka kwa nayitrogeni kumawonjezeranso kukana kwa weld ku dzimbiri lobowoka ndi lobowoka, zomwe zimapangitsa AF2209-15 kukhala yoyenera kugwiritsidwa ntchito kwambiri m'mafakitale monga mafuta ndi gasi, kukonza mankhwala ndi uinjiniya wakunja kwa dziko.
Chimodzi mwa zinthu zofunika kwambiri za AF2209-15 ndi yokutidwa kwake ndi haidrojeni yochepa, komwe kumachepetsa kwambiri chiopsezo cha kusweka kwa haidrojeni. Izi zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito powotcherera pomwe hydrogen imaphwanyika, zomwe zimapangitsa kuti weld ikhale yolimba komanso yokhalitsa. Arc yokhazikika ya electrode ndi mawonekedwe ake osalala zimathandizanso kuti igwiritsidwe ntchito mosavuta komanso kuti igwire bwino ntchito, zomwe zimapangitsa kuti ntchito zowotcherera zikhale zogwira mtima komanso zodalirika.
Kuwonjezera pa kugwira ntchito bwino kwambiri kwa welding, AF2209-15 yapangidwa ndi cholinga chogwiritsa ntchito zinthu zosiyanasiyana komanso zosavuta. Kaya imagwiritsidwa ntchito pa malo athyathyathya, opingasa, oyima kapena apamwamba, electrode iyi imapereka ma weld ogwirizana komanso apamwamba. Ndi yoyenera kugwiritsa ntchito zinthu zosiyanasiyana zoyambira, kuphatikizapo zitsulo zosapanga dzimbiri za UNS S31803, S32205 ndi S2205, zomwe zimapangitsa kuti ikhale yankho logwiritsidwa ntchito kwambiri pa ntchito zosiyanasiyana zowelding.
Ponseponse, AF2209-15 ikukhazikitsa muyezo watsopano wa ma electrode olumikizira zitsulo zosapanga dzimbiri, zomwe zikupereka magwiridwe antchito osayerekezeka, kudalirika komanso kusinthasintha. Electrode iyi ndi yotsika kwambiri pa nayitrogeni, yokhala ndi hydrogen yochepa komanso yolimba kwambiri, ndipo ndiyo njira yabwino kwambiri yolumikizirana bwino komanso yolimba. Kaya mukugwira ntchito pa mapulojekiti ofunikira kwambiri kapena ntchito zaukadaulo wolondola, AF2209-15 ndiye yankho loyenera pamavuto ovuta kwambiri olumikizirana.
