Ukushiselai-electrode inezingxenye ezimbili, ingqikithi ne-coating.Ama-electrode we-Metal core welding angaphandle kopende (okwenamathela) ingcindezi efanayo esetshenziswa kumongo we-solder ngokucophelela.Izinhlobo ezahlukene ze-welding, i-welding core ihlukile.I-welding electrode core metal core, ukuze kuqinisekiswe ikhwalithi nokusebenza kwe-weld, i-butt okuqukethwe okuyinhloko kwesici sensimbi kunemithetho eqinile, ikakhulukazi okuqukethwe kokungcola okuyingozi (okufana nesibabule, i-phosphorus, njll.), kufanele kube yimikhawulo eqinile kunento eyisisekelo.Isikhwama semithi ye-Electrode sasibizwa ngokuthi i-weld metal core coated core.I-Welding core wire ngokuvamile inobude nobubanzi obuthile.Lapho i-soldering, i-welding core inemiphumela emibili: Okokuqala, ukuqhuba i-welding current, amandla e-arc aguqulwa abe ukushisa, intambo yesibili yomgogodla ngokwayo isetshenziswa njengensimbi yokugcwalisa enoketshezi oluncibilikisiwe lwensimbi yokuhlanganiswa kwensimbi.

Ingcindezi isetshenziswa ebusweni bento ebizwa ngokuthi i-core solder coating.I-Electrode coating idlala indima ebaluleke kakhulu enqubweni yokushisela.Ukusetshenziswa kwe-electrode welding yesikhumba esikhanyayo engenazidakamizwa, inqubo yokushisela, umoya-mpilo ne-nitrogen emoyeni kuzoba ukungena okukhulu kwensimbi encibilikisiwe, insimbi yensimbi nezinto ezizuzisayo zekhabhoni, i-silicon, i-manganese oxide kanye nokwakheka kwe-nitride kwama-oxide ahlukahlukene kanye i-nitrides, futhi ihlala ku-weld, i-weld slag, noma ibangele imifantu.Ukuncibilika ku-puddle yegesi kungase kubangele inani elikhulu le-weld porosity, lezi zici zingenza izici zemishini ze-weld (amandla, inani lomthelela, njll.) zinciphise kakhulu, kuyilapho i-weld brittle.

Ama-electrode welding we-SMAW asetshenziswa ukunamathela kanye ne-welding core eyakhiwe izingxenye ezimbili.Lapho i-welding, i-electrode yokushisela njengesandla esisodwa, futhi kusukela ku-pilot arc current conduction effect, ukuze phakathi kwama-electrode kanye nesisekelo sensimbi ku-arc eqhubekayo, ezinzile, ukunikeza ukushisa okudingekayo ukuze kuncibilike i-solder.Ngakolunye uhlangothi, futhi njengensimbi yokugcwalisa i-welding yengezwe ku-weld ukuze ibe ingxenye enkulu yensimbi yokushisela.Ngakho-ke, ukwakheka kwekhwalithi ye-welding kanye ne-welding, ukwakheka kwamakhemikhali ensimbi ye-weld kuthinta ngqo izakhiwo zemishini kanye nezakhiwo zomzimba.Ngaphezu kwalokho, i-electrode nayo inethonya elikhulu ekuzinzeni kwekhwalithi yokubukeka kwe-weld, inqubo yokushisela njengokukhiqiza kwe-welding.
