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 engaphansi - indawo yokushisela imbozwe ungqimba oluvikelayo lwe-flux, ucingo lwe-photonic olwenziwa nge-filler metal lufakwa kungqimba olugelezayo, futhi insimbi yokushisela ikhiqiza i-arc, i-arc engcwatshwe ngaphansi kwesendlalelo se-flux, futhi ukushisa okukhiqizwe yi-arc kuncibilikisa intambo yokushisela, i-flux kanye nesisekelo sensimbi ukuze kwakhiwe i-weld, futhi inqubo yokushisela iyazenzakalela.Okuvame ukusetshenziswa kakhulu yi-manual arc welding.
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 (imbobo efafaza ilangabi le-acetylene-oksijeni ngesikhathi sokushiselwa kwegesi) ngqo phansi kwe-groove ukuqinisekisa ukungena kokushisela, futhi kulungele ukususwa kwe-slag nokwenza lula okudingekayo. ukunyakaziswa kwenduku yokushisela emseleni ukuze uthole ukuhlangana okuhle.Ukuma nosayizi we-groove ikakhulukazi kuncike ezintweni ezishiselwe kanye nokucaciswa kwayo (ikakhulukazi ukushuba), kanye nendlela yokushisela eyamukelwayo, uhlobo lwe-weld seam, njll. Izinhlobo ezijwayelekile ezifakwe kwizicelo ezingokoqobo yilezi: amalunga agobile - afaneleka 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 - ifanele izinto 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 kokushisela kwe-arc welding yilezi: uhlobo lwenduku yokushisela (kuye ngokuthi impahla yesisekelo), ububanzi be-electrode (kuye ngokuthi ubukhulu be-weldment, isikhundla se-weld, inani lezingqimba zokushisela, isivinini sokushisela, i-welding current, njll. .), i-welding current, i-welding layer, njll. Ngaphezu kokushisela kwe-arc evamile okukhulunywe ngenhla, ukuze kuthuthukiswe izinga lokushisela, kuyasetshenziswa futhi: i-gas shielded arc welding: isibonelo,i-argon arc weldingusebenzisa i-argon njengegesi evikelayo endaweni yokushisela, i-carbon dioxide ivikelwe i-welding isebenzisa i-carbon dioxide njengegesi evikelayo endaweni yokushisela, njll., isimiso esiyisisekelo ukushisela nge-arc njengomthombo wokushisa, futhi ngesikhathi esifanayo ngokuqhubekayo. fafaza igesi evikelayo embhobhweni wesibhamu sokufutha ukuze uhlukanise umoya ensimbi encibilikisiwe endaweni yokushisela ukuze uvikele i-arc nensimbi ewuketshezi echibini lokushisela ekungcoleni komoyampilo, i-nitrogen, i-hydrogen nokunye ukungcola ukuze kuzuzwe inhloso yokuthuthukisa ukushisela. izinga Welding.I-Tungsten argon arc welding: induku ye-tungsten yensimbi enephuzu eliphakeme lokuncibilika isetshenziswa njenge-electrode eyenza i-arc lapho ishiselwa, kanye ne-arc welding ngaphansi kokuvikelwa kwe-argon, evame ukusetshenziswa ensimbi engagqwali, ingxubevange yokushisa okuphezulu nokunye ukushisela. nezidingo eziqinile.I-Plasma arc welding: Lena indlela yokushisela eyakhiwe yi-tungsten argon arc welding, endaweni yokuvula umlomo wombhobho womshini ukwahlulela usayizi wamanje we-Arc welding: yamanje encane: ubuhlalu bokushisela obuncane, ukungena okungajulile, ukwenza kalula kube kuphezulu kakhulu, akuhlanganisiwe, akushiselwe. ngokusebenzisa, i-slag, i-porosity, i-weld rod adhesion, ukuphuka kwe-arc, akukho i-arc yomthofu, njll. Umsinga mkhulu: ubuhlalu be-weld bubanzi, ukujula kokungena kukhulu, umphetho wokuluma, ukushiswa, imbobo yokushwabana, i-splash inkulu, i-overburn, i-deformation inkulu, i-weld tumor nokunye.
