Carbon electrode: Izakhiwo kanye Izicelo

Carbon electrode esetshenziselwa ukusika metal emoyeni kuhhavini. Ngaphandle ukuzisebenzisa ukukhiqiza metal weld ukukhubazeka isuswe metal amashidi isipikili usike nokwenza ezinye imisebenzi. Carbon electrode eyenziwe kagesi carbon amorphous. imikhiqizo Iphele kukhona ebusweni ishidi-omnyama ziyizindilinga isiyingi, esigabeni cross zazo kuhluka amamilimitha angu-6 kuya ku-18. Standard obuphelele izinduku kuyinto 25-70 ngamasentimitha.

Ukuze ukusika izinhlobo ezahlukene carbon lensimbi electrode ngensimbi engeli. Ngakho, ukuze ukucutshungulwa izinsimbi ayoni komunye umkhawulo engela induku ucije degree angaba 65. Ukuze wenze Welding ayoni metal izinto, kuhlanganise i-hardfacing umkhiqizo electrode imimese engela degrees 30.

Phakathi womshini electrode wasebenzisa ubuchwepheshe dekstruzii noma babumba futhi ukwelashwa ukushisa kwayo. Umkhiqizo base kuhlanganisa coke noma ilahle, bese wengeza binders ehlukahlukene (itiyela, iphimbo, njll). Kwezinye izimo, le electrode carbon zimumethe powder metal noma shavings.

Imikhiqizo asetshenziswa kulezo zimboni. Basuke esetshenziselwa ukusika izinto steel, okwenza emigodini doped, carbon and ingxubevange ongaphakeme lezinsimbi. Ngaphezu cut zabo besebenzisa ithusi, insimbi engagqwali noma oluncane kanye nezinye Alloys asetshenziswe ekukhiqizeni metal izakhiwo e isiqoqi sama-softwe, shipbuilding, steel umkhakha.

Zokushisela carbon electrode ubé high kakhulu. Kuye kuqhathaniswa nezinye izinhlobo ezivamile ukusika izinzuzo eziningi. Uma wenza Welding usebenzisa electrode carbon isetshenziswa carbon, umoya onomfutho noma kagesi, okuvumela ukuba enze ukusika omuhle kakhulu ukususwa metal. umsebenzi zokushisela wenziwa nokusetshenziswa emoyeni onomfutho noma arc kagesi, okuyinto liyancibilika kwensimbi nje kuphela kodwa futhi okususiwe ngokwayo nge ukusakaza emoyeni.

Le ndlela Welding imikhiqizo metal has izici zayo siqu. Ngokwesibonelo, wonke umsebenzi engenziwa kuphela ngesikhathi samanje njalo, futhi ubude arc kufanele ibe uhla 6-15 amamilimitha angu. Kulokhu, lo arc ephakamayo kalula kakhulu futhi has a ukuzinza okwanele. Nokho, arc uzolahlekelwa ukuzinza, kanye electrode ngeke vaporize futhi ashiswe nge polarity kwenzeka okuphambene.

Kwakheka lapho Welding izinto nge-carbon electrode arc ubukisa sensitivity high ehambisana nesimo sezulu esingesihle (imvula, dutyu kazibuthe, igesi notshwala). Ngaphezu kwalokho, lapho befeza Welding umsebenzi, esebenzisa i-carbon electrode, le arc uthola kahle ngaphansi kuqhathaniswa ngenqubo evamile metal rod. Nokho, ukubaluleka carbon izinduku ayikwazi phansi. Bona ukuvumela Welding nonferrous izinto kuwebhu okusansimbi ukwenza inotiyela elektroprihvatkah hardmetals nge samanje 1 KA ububanzi.
