1.Ukuhlukaniswa
I-arc welding ingahlukaniswa ibei-arc welding ye-manual, i-semi-automatic (arc) welding, i-automatic (arc) welding. I-automatic (arc) welding ngokuvamile ibhekisela ekushiseni okuzenzakalelayo kwe-arc okuzenzakalelayo - indawo yokushisela imbozwe ungqimba oluvikelayo lwe-flux, ucingo lwe-photonic olwenziwe nge-filler metal lufakwa kungqimba lwe-flux, futhi insimbi yokushisela ikhiqiza i-arc, i-arc ingcwatshwa ngaphansi kwesendlalelo se-flux, futhi ukushisa okukhiqizwa yi-arc kuncibilikisa intambo yokushisela, isisekelo sensimbi kanye nenqubo ye-weld yokwenza i-automated wire. Okuvame ukusetshenziswa kakhulu ukushisela i-arc manual.
2.Inqubo eyisisekelo
Inqubo eyisisekelo ye-arc welding manual imi kanje: a. Hlanza indawo yokushisela ngaphambi kokushisela ukuze ungaphazamisi ikhwalithi ye-arc ignition kanye ne-weld seam. b. Lungiselela ifomu elihlangene (uhlobo lwe-groove). Iqhaza le-groove ukwenza induku yokushisela, intambo yokushisela noma ithoshi (umbhobho ofutha ilangabi le-acetylene-oksijeni ngesikhathi sokushisela igesi) ngqo phansi kwe-groove ukuze kuqinisekiswe ukungena kokushisela, futhi kulungele ukususwa kwe-slag nokwenza lula ukuvuleka okudingekile kwenduku yokuhlanganisa ukuze kutholakale i-good groove. Ukuma nobukhulu be-groove ngokuyinhloko kuncike ezintweni ezishiselwe kanye nokucaciswa kwayo (ikakhulukazi ukushuba), kanye nendlela yokuthungatha eyamukelwayo, uhlobo lwe-weld seam, njll Izinhlobo ezijwayelekile ezigobile ekusetshenzisweni okusebenzayo yilezi: amalunga agobile - afanele izingxenye ezincane ezinobukhulu obungu-<3mm; I-Flat groove - ifanele izingxenye ezincane ze-3 ~ 8mm; I-groove emise okwe-V - ifanele izinto zokusebenza ezinobukhulu obungu-6 ~ 20mm (welding ohlangothini olulodwa); Umdwebo we-Schematic we-weld groove yohlobo lwe-X-type groove - ilungele izingcezu zokusebenza ezinobukhulu obuyi-12 ~ 40mm, futhi kukhona imisele ye-X elinganayo ne-asymmetrical (i-welding enezinhlangothi ezimbili); I-groove emise okwe-U - ilungele ama-workpieces anobukhulu obungama-20 ~ 50mm (welding ohlangothini olulodwa); I-groove emise okwe-U ephindwe kabili - ifanele izinto zokusebenza ezinobukhulu obungu-30~80mm (i-welding enezinhlangothi ezimbili). I-groove angle ivamise ukuthathwa ukusuka ku-60 kuye ku-70 °, futhi inhloso yokusebenzisa imiphetho ebuthuntu (ebuye ibizwe ngokuthi ukuphakama kwezimpande) ukuvimbela ukushisela ekushiseni, kuyilapho igebe liwukwenza lula ukungena kwe-welding.
3.Amapharamitha amakhulu
Imingcele ebaluleke kakhulu ekucacisweni kwe-welding ye-arc welding yilezi: uhlobo lwe-welding rod (kuye ngokuthi impahla yesisekelo sesisekelo), ububanzi be-electrode (kuye ngokuthi ukushuba kwe-weldment, isikhundla se-weld, inani lezingqimba zokushisela, isivinini se-welding, i-welding yamanje, njll.), i-welding current, i-welding layer, njll. ukushisela i-arc evikelekile: isibonelo,i-argon arc weldingusebenzisa i-argon njengegesi evikelayo endaweni yokushisela, i-carbon dioxide evikelekile yokushisela usebenzisa i-carbon dioxide njengegesi evikelayo endaweni yokushisela, njll., isimiso esiyisisekelo siwukushisela nge-arc njengomthombo wokushisa, futhi ngesikhathi esifanayo ngokuqhubekayo fafaza igesi evikelayo kusuka ku-nozzle yesibhamu se-spray ukuze uhlukanise umoya endaweni yokuthungatha futhi uvikele insimbi endaweni encibilikisiwe ukuvikela insimbi ensimbi. umoya-mpilo, i-nitrogen, i-Hydrogen nokunye ukungcola ukuze kuzuzwe inhloso yokuthuthukisa izinga lokushisela. I-Tungsten argon welding ye-tungsten: induku ye-tungsten yensimbi enezinga eliphakeme lokuncibilika isetshenziswa njenge-electrode eyenza i-arc lapho ishiselwa, kanye ne-arc welding ngaphansi kokuvikelwa kwe-argon, evame ukusetshenziswa ensimbi engagqwali, i-alloy high-temperature kanye nokunye ukushisela okunezidingo eziqinile. I-Plasma arc welding: Lena indlela yokushisela eyakhiwe yi-tungsten argon arc welding, ekuvuleni kwe-nozzle yomshini we-Arc welding usayizi wamanje isahlulelo: yamanje encane: ubuhlalu obuncane be-welding, ukungena okungajulile, kulula ukwakha phezulu kakhulu, hhayi okuhlanganisiwe, okungahlanganisiwe, i-slag, i-porosity, i-weld rod adhesion, i-arc ye-arc enkulu, i-arc ye-arc enkulu, njll. ububanzi, ukujula kokungena kukhulu, unqenqema lokuluma, ukushiswa, imbobo yokuncipha, i-splash inkulu, ukushisa ngokweqile, ukuguqulwa kukhulu, i-weld tumor nokunye.
