Uma usebenzisa ama-electrode we-arc welding, umshini wokushisela odingekayo ulula, futhi ungakhetha umshini wokushisela we-AC noma we-DC.Ngaphezu kwalokho, asikho isidingo semishini yokusiza eyeqile lapho i-welding, inqobo nje uma kukhona amathuluzi asizayo alula.Le mishini yokushisela ilula ngesakhiwo, ishibhile ngentengo, futhi kulula ukuyinakekela.Ngenxa yokutshalwa kwezimali okuncane ekuthengeni imishini, i-electrode arc welding isetshenziswe kabanzi ekukhiqizeni izimboni.
Ubuchwepheshe be-Electrode arc welding abunawo umsebenzi wokugcwalisa insimbi endaweni yokushisela, kodwa futhi akudingekile ukwethula igesi eyengeziwe yokuvikela ngesikhathi sokusetshenziswa.Ngesikhathi sokushisa kwe-arc, i-current phakathi kwe-electrode kanye ne-weldment idala ichibi elincibilikisiwe, kuyilapho i-electrode ngokwayo ikhiqiza imikhiqizo evuthayo esebenzisana ukuze yakhe igesi evikelayo evikela ichibi elincibilikisiwe kanye ne-weld.Ngaphezu kwalokho, ukwakheka kwenduku yokushisela kuklanyelwe ukumelana nomoya kakhulu futhi kuqine ekumelaneni komoya, okuvumela ukushisela kwekhwalithi ephezulu endaweni enomoya.
I-Electrode arcukushiselainezinzuzo zokusebenza okulula kanye nobubanzi besicelo esibanzi.Kufanelekile ukushisela inombolo encane yemikhiqizo noma ama-batches amancane, ikakhulukazi lawo ma-welds okunzima ukuwafaka ngemishini efana nokuma okungavamile nobude obufushane.Uma usebenzisa ubuchwepheshe be-stick arc welding, indawo yokushisela ayinqunyelwe, futhi ingasebenza ngokuguquguqukayo ngisho nasezikhaleni ezincane noma ezikhundleni eziyinkimbinkimbi.Ngaphezu kwalokho, imishini edingekayo kubuchwepheshe be-electrode arc welding ilula, ayikho igesi elisizayo elisetshenziswayo, futhi izinga lamakhono opharetha aliphezulu kakhulu.
Ukusebenza kobuchwepheshe be-electrode arc welding kubanzi kakhulu, futhi kufanelekile ukushisela cishe zonke izinsimbi ezijwayelekile nama-alloys.Ngokukhetha i-electrode efanele, i-welding ingafinyelelwa ezintweni ezihlukahlukene, kuhlanganise nensimbi ephansi ye-alloy, i-carbon steel, insimbi ephezulu ye-alloy kanye nezinsimbi ezihlukahlukene ezingenayo insimbi.Ngaphezu kwalokho, ama-electrode angasetshenziselwa ukushisela izinhlobo ezahlukene zezinto zokusebenza, njengezinsimbi ezingafani, kanye nemisebenzi ehlukahlukene yokushisela efana nokulungisa ukushisela kwensimbi eyinsimbi kanye nokushisela okungaphezulu kwezinto ezihlukahlukene zensimbi.I-electrode ngokwayo inganikeza inani elithile legesi elivikelayo ukugwema izinkinga ezifana ne-oxidation ye-weld.Ngesikhathi esifanayo, i-filler metal nayo ingathuthukisa amandla nokuqina kwe-weld.Ezimweni ezinzima ezifana nemimoya enamandla, ubuchwepheshe be-electrode arc welding bungabuye bugcine imiphumela emihle, buqinisekise ikhwalithi nokusebenza kahle kwemisebenzi yokushisela.
Inqubo yokushisela inqunywa ngokusho kwezakhiwo zensimbi, futhi izinto ezahlukene zensimbi zidinga amasu okushisela ahambisanayo.Ngokuvamile, i-carbon steel, i-low alloy steel, insimbi engagqwali, insimbi engangeni ekushiseni, ithusi nama-alloys azo kungashiselwa ngezindlela ezivamile zokushisela.Kodwa-ke, kwezinye izinto zensimbi, njengensimbi ekhonjiwe, insimbi enamandla kakhulu nensimbi eqinile, ukushisa kwangaphambi kwesikhathi noma ukwelashwa kwangemuva kokushisa kungase kudingeke, noma amasu okushisela ama-hybrid angasetshenziswa.Kodwa-ke, izinsimbi ezincibilikayo eziphansi (njengezinki, umthofu, ithini nama-alloys azo) nezinsimbi eziphikisayo (njenge-titanium, i-niobium, i-zirconium, njll.) azikwazi ukushiselwa kusetshenziswa izinqubo zokushisela ezivamile.Ngakho-ke, ngaphambi kwe-welding, kuyadingeka ukuhlaziya ngokucophelela futhi uhlole izinto ezibonakalayo, bese ukhetha ubuchwepheshe obufanele be-welding kanye nenqubo ngokusho kwesimo sangempela.
Imikhiqizo enjalo ivame ukuba nezakhiwo eziyinkimbinkimbi kanye nokwakheka okuhlukahlukene, okudinga ukusebenza ngesandla kanye nezinqubo zokushisela ezibucayi ukuze kuqinisekiswe ikhwalithi nokuthembeka kokushisela.Njengoba inqubo yokushisela idinga amakhono ochwepheshe kanye nesipiliyoni, izindlela zokukhiqiza ezenziwe ngomshini nezizenzakalelayo azilufanele lolu hlobo lomkhiqizo.Ngesikhathi esifanayo, lolu hlobo lomkhiqizo ngokuvamile luba nenani eliphezulu leyunithi noma iqoqo elincane lokukhiqiza, futhi lidinga ukukhiqizwa ngendlela ehlosiwe.Ngakho-ke, kulolu hlobo lomkhiqizo, indlela yokukhiqiza efanelekile kakhulu i-welding manual kanye nokukhiqizwa kwe-batch encane ukuqinisekisa ikhwalithi nokusebenza kahle kokukhiqiza.Ngesikhathi esifanayo, ubuchwepheshe obuchwepheshile nolwazi kuyadingeka ekufakweni nasekulungiseni ukuze kuqinisekiswe ukusetshenziswa okuvamile nokuphepha komkhiqizo.
