Emkhakheni wokushisela kwesakhiwo kanye nezimboni, ukukhethwa kwezinto zokugcwalisa ezifanele kubalulekile ekuqinisekiseni ubuqotho nokusebenza kahle kokubambisana.I-Electrode Yokushisela Insimbi Yekhabhoniisigaba siyisisekelo, sihlanganisa izinhlobo ezahlukene ezenzelwe ukuhlangabezana nezidingo ezithile zemishini nezenqubo. Phakathi kwalezi, i-AWS E7015, evame ukubizwa ngokuthi imodeli 507 kwezinye izifunda, imelela i-electrode ephansi ye-hydrogen esetshenziswa kabanzi ekusetshenzisweni kwensimbi yekhabhoni ebalulekile.
Isici esiyinhloko sale Carbon Steel Welding Electrode ethile ukuhlanganiswa kwayo kwe-sodium ephansi ye-hydrogen. Lokhu kuhlanganiswa kokuhlanganiswa kubalulekile ekunciphiseni ukufakwa kwe-hydrogen ensimbini yokushisela, okunciphisa kakhulu ingozi yokuqhekeka okubangelwa yi-hydrogen, ikakhulukazi ezingxenyeni ezijiyile noma ngaphansi kwezimo ezivinjelwe. Insimbi efakwe ebhodweni ibonisa ukuqina okuhle kakhulu, ukuqina, kanye nokumelana nokuqhekeka okuphelele, okwenza ifanelekele izindawo ezidinga kakhulu lapho ukuthembeka kwesakhiwo kubaluleke kakhulu.
Ngokombono wokusebenza, lokhuI-Electrode Yokushisela Insimbi Yekhabhonikudinga ukusetshenziswa kwe-Direct Current Electrode Positive (DCEP) polarity. Lesi sici sikagesi sinikeza ukungena okujulile kanye ne-arc ezinzile. Okuphawulekayo ukuthi i-electrode yenzelwe ukushisela kuzo zonke izindawo, inikeza ukuguquguquka kwezicelo ezisicaba, ezivundlile, eziqondile, kanye nezingaphezulu. Lokhu kwenza kube ithuluzi eliwusizo lokwenziwa okuyinkimbinkimbi kanye nokwakhiwa kwensimu lapho ukuqondiswa kokushisela kuyahlukahluka khona.
Ububanzi bokusetshenziswa kwale Electrode Yokushisela Insimbi Yekhabhoni Ephansi ye-hydrogen buchazwe kahle. Inconywa kakhulu ekushiseleni izinsimbi zekhabhoni ephakathi kanye nezakhiwo ezithile zensimbi ezine-alloy ephansi. Izinto eziyisisekelo ezijwayelekile zifaka amazinga afana ne-09Mn2Si, Q345 (insimbi evamile yesakhiwo yaseShayina elingana ne-ASTM A572 Gr. 50), kanye ne-09Mn2V. Izakhiwo zayo ziyenza ifanelekele umsebenzi wokukhiqiza nokulungisa ezimbonini ezifana nokwakha, ukwakha imikhumbi, ukwenziwa kwemikhumbi yokucindezela, kanye nemishini esindayo evamile lapho ukushisela kufanele kufane noma kudlule ukuqina kwensimbi yesisekelo.
Imodeli ye-AWS E7015 / J507 iyisibonelo somkhiqizo obalulekile ngaphakathiI-Electrode Yokushisela Insimbi Yekhabhoniukuhlukaniswa. Isembozo sayo esingena-hydrogen ephansi, kuhlanganiswe nekhono lokuma kuzo zonke izindawo kusetshenziswa i-DCEP, sibhekana nezinselele ezivamile ekushiseni izinsimbi ezisengozini. Ngokuletha insimbi egciniwe enobuqotho obuphezulu, izakhiwo ezinhle zemishini, kanye nokuthambekela okuncishisiwe kokuqhekeka, le electrode inikeza ikhambi elithembekile kochwepheshe abasebenza ezinhlanganisweni zensimbi ezibucayi zekhabhoni kanye nensimbi engena-alloy ephansi emikhakheni eyahlukene yezimboni.
