Ama-electrode e-welding ayizintambo zensimbi ezibhakwe kuma-chemical coatings.Induku isetshenziselwa ukusekela i-arc yokushisela nokuhlinzeka ngensimbi yokugcwalisa edingekayo ukuze ilunga lishiselwe.I-coating ivikela insimbi emonakalweni, iqinisa i-arc, futhi ithuthukise ukushisela.Ububanzi bocingo, ngaphansi kokumbozwa, bunquma ubukhulu benduku yokushisela.Lokhu kuvezwa ngezingxenyana ze-intshi njengokuthi 3/32″, 1/8″, noma 5/32.”I-diameter encane isho ukuthi idinga okwamanje kancane futhi ifaka inani elincane lensimbi yokugcwalisa.
Uhlobo lwensimbi eyisisekelo olushiselwayo, inqubo yokushisela nomshini, nezinye izimo inquma uhlobo lwe-electrode yokushisela esetshenziswayo.Isibonelo, i-carbon low noma "insimbi emnene" idinga induku yokushisela yensimbi emnene.Insimbi yokushisela, i-aluminium noma ithusi idinga izinduku zokushisela nemishini ehlukene.
I-flux coating kuma-electrode inquma ukuthi izosebenza kanjani phakathi nenqubo ye-welding yangempela.Okunye kokushiswa kwe-coating kanye ne-flux eshile kwenza intuthu futhi isebenze njengesihlangu ezungeze "ichibi" lokushisela, ukuyivikela kulowo moya ozungezile.Ingxenye ye-flux iyancibilika futhi ixubane nocingo bese intanta ukungcola phezulu.Lokhu kungcola kwaziwa ngokuthi "i-slag."I-weld eqediwe ingaba brittle futhi ibe buthakathaka uma kungenjalo ngenxa ye-flux.Lapho ukuhlanganiswa okuhlanganisiwe kupholile, i-slag ingasuswa.Isando esihlikihlayo nebhulashi locingo kusetshenziswa ukuhlanza nokuhlola indawo yokushisela.
Ama-electrode ensimbi-arc welding angase aqoqwe njengama-electrode angenalutho, ama-electrode ambozwe ukukhanya, nama-arc avikelekile noma ama-electrode agqinsiwe asindayo.Uhlobo olusetshenziswayo luncike ezicini ezithile ezidingekayo ezihlanganisa: ukumelana nokugqwala, i-ductility, amandla aqine kakhulu, uhlobo lwesisekelo sensimbi okufanele sishiselwe;kanye nendawo yokushisela eyisicaba, evundlile, eqondile, noma ngaphezulu.
