D132(B-83)Ndodo YolimbaIli ngati electrode yapadera yolumikizira yotsika ndi haidrojeni yopangidwira ntchito zokonzanso zofunikira kwambiri. Ndodo yolumikizira ya arc iyi imachita bwino kwambiri pobwezeretsa zinthu zosweka zomwe zawonongeka zomwe zakhudzidwa ndi kusweka pang'ono komanso mphamvu zopanikizika kwambiri. Yopangidwa ngati ndodo yolumikizira pamwamba komanso yankho lokonzanso, imapanga ma arc okhazikika komanso otsika komanso osalala pomwe imachepetsa zoopsa zosweka chifukwa cha haidrojeni. Kapangidwe kake kamatsimikizira kuti mikanda imayikidwa bwino komanso imaoneka bwino nthawi zonse, zomwe zimapangitsa kuti ikhale yoyenera kukonza makina amafakitale, zida zaulimi, ndi zida zamagalimoto zomwe zimafuna kukonzanso kwakukulu komanso kulimbitsa pamwamba.
Mafotokozedwe aukadaulo akuwonetsa ndodo'luso lapadera. Chitsulo chosungunula chomwe chaikidwacho chili ndi mphamvu zambiri zopanikiza ndipo chimasunga makina abwino kwambiri–kulola ntchito zothira pambuyo pa weld monga kutembenuza, kugaya, ndi kupala popanda kuwononga umphumphu. Khalidweli ndi lofunika kwambiri pazigawo zolondola zomwe zimafuna kupirira kolimba pambuyo poika pamwamba. Pokhala ndi electrode yochepa ya haidrojeni, limachepetsa kwambiri kutseguka kwa ming'alu ndi kuzizira, makamaka m'magawo okhuthala kapena malo olumikizirana kwambiri. Dongosolo lolinganiza bwino la flux limapereka kuchotsedwa kwa slag ndi kuchepetsa kufalikira kwa madzi, zomwe zimapangitsa kuti ntchito igwire bwino ntchito.
Pa ntchito zomwe zimafuna kukana kuvala pang'ono,Ndodo Yolimbaimapereka ntchito yabwino kwambiri. Kapangidwe ka alloy kamapanga gawo lolimba, lolimba lomwe limalimbana bwino ndi kuwonongeka kwa zinthu zolemera m'malo monga kugwirira ntchito zinthu zambiri, kusuntha nthaka, kapena kupanga. Mosiyana ndi njira zina zofooka, D132(B-83)'Ma depositi amatenga mphamvu ya kugwedezeka pamene akusunga kuuma pamwamba, zomwe zimawonjezera nthawi yogwira ntchito ya zigawozo kwambiri. Ndi yoyenera makamaka pomanganso ma shaft, ma rollers, zigawo zophwanya, ndi masamba a mafakitale omwe ali ndi kukangana kosalekeza ndi kupanikizika.
Zotsatira zabwino kwambiri zimafuna kutsatira magawo a welding: Yatsani zigawozo mpaka 250-300°C (482-572)°F) kutengera kulemera, sungani kutentha kwa interpass, ndipo gwiritsani ntchito DC reverse polarity (electrode positive). Sungani ndodo m'zidebe zotsekedwa pa 250-300°F (121-149)°C) ndikuphikanso ngati yaikidwa pamalo onyowa opitirira 50% kwa maola opitilira 4. Ikani mikanda m'magawo opapatiza, opyapyala kuti muchepetse kukhuthala ndikulimbitsa kwambiri. Kuziziritsa pang'onopang'ono pambuyo pothira pansi pa chotenthetsera kumalimbikitsidwa kuti mugwiritse ntchito mofunikira kuti mupewe kuwonongeka kwa haidrojeni.
D132(B-83)Ndodo Yolimbaimapereka njira yodalirika komanso yotheka kuigwiritsa ntchito polimbana ndi kuwonongeka ndi kubwezeretsa miyeso. Kapangidwe kake kopanda haidrojeni, kuphatikiza mphamvu yolimba komanso kukana kuwonongeka, zimapangitsa kuti ndodo yolumikizira pamwamba iyi ikhale yofunika kwambiri pokonza ndi kumanganso mapulogalamu m'mafakitale olemera. Posankha electrode iyi, mainjiniya amaonetsetsa kuti zinthu zomwe zabwezeretsedwanso zikugwiranso ntchito bwino pomwe zikugwira ntchito nthawi yayitali pansi pa zovuta.
