Gusudira birashobora gukoresha imashini yo gusudira AC cyangwa DC.Iyo ukoresheje imashini yo gusudira DC, habaho guhuza kwiza no guhuza inyuma.Ibintu nka electrode yakoreshejwe, imiterere yibikoresho byubwubatsi, nubwiza bwo gusudira bigomba kwitabwaho.
Ugereranije n'amashanyarazi ya AC, amashanyarazi ya DC arashobora gutanga arc ihamye kandi ihererekanya neza.- Iyo arc imaze gutwikwa, arc arc irashobora gukomeza gutwikwa.
Iyo ukoresheje amashanyarazi ya AC, kubera ihinduka ryerekezo ya voltage na voltage, kandi arc igomba kuzimya no kongera gutwikwa inshuro 120 kumasegonda, arc ntishobora gutwika ubudahwema kandi buhamye.
Kubijyanye numuyoboro muto wo gusudira, DC arc igira ingaruka nziza yo guhanagura icyuma cyashongeshejwe kandi gishobora kugena ubunini bwamasaro yo gusudira, kubwibyo birakwiriye cyane gusudira ibice bito.Imbaraga za DC zirakwiriye cyane hejuru no gusudira guhagarikwa kuruta ingufu za AC kuko DC arc ni ngufi.
Ariko rimwe na rimwe arc kuvuza amashanyarazi ya DC nikibazo gikomeye, kandi igisubizo nuguhindura amashanyarazi ya AC.Kuri AC na DC ebyiri-zifite intego ya electrode yagenewe gusudira amashanyarazi ya AC cyangwa DC, porogaramu nyinshi zo gusudira zikora neza mugihe amashanyarazi ya DC.
Kuri electrode isanzwe yubatswe hamwe na electrode ya aside, byombi AC na DC birashobora gukoreshwa.Iyo ukoresheje imashini yo gusudira DC kugirango usudire amasahani yoroheje, nibyiza gukoresha DC ihuza.
Mubisanzwe, umurongo utaziguye urashobora gukoreshwa muburyo bwo gusudira kugirango ubone kwinjira cyane.Byumvikane, guhuza ibyerekezo bihuza nabyo birashoboka, ariko kubwinyuma yo gusudira isahani yibyibushye hamwe na groove, biracyari byiza gukoresha umurongo uhuza uhuza.
Electrode yibanze muri rusange ikoresha DC ihuza ihuza, ishobora kugabanya ubukana no gutatana.
(2)Molten argon arc gusudira (MIG welding)
Gusudira ibyuma bya arc muri rusange bifashisha DC ihinduranya, idahindura arc gusa, ahubwo ikanakuraho firime ya okiside hejuru yubudodo mugihe cyo gusudira aluminium.
(3) Tungsten argon arc gusudira (TIG welding)
Tungsten argon arc gusudira ibice byibyuma, nikel hamwe nuruvange rwayo, umuringa hamwe nuruvange rwayo, umuringa hamwe nuruvange rwarwo bishobora guhuzwa gusa numuyoboro utaziguye.Impamvu nuko niba imiyoboro ya DC ihinduwe hanyuma tungsten electrode igahuzwa na electrode nziza, ubushyuhe bwa electrode nziza izaba nyinshi, ubushyuhe buzaba bwinshi, kandi electrode ya tungsten izashonga vuba.
Gushonga byihuse cyane, ntibishobora gutuma arc yaka neza igihe kirekire, hamwe na tungsten yashongeshejwe igwa muri pisine yashongeshejwe bizatera tungsten gushiramo kandi bigabanye ubwiza bwa weld.
（4）CO2 ikingira gusudira (MAG welding)
Kugirango ugumane arc ihamye, imiterere nziza yo gusudira, no kugabanya spatter, gusudira gaze ya gaze ya CO2 muri rusange ikoresha ihuza rya DC .Nyamara, mugusudira gusudira no gusana gusudira ibyuma, birakenewe kongera igipimo cyo guta ibyuma no kugabanya gushyushya akazi, na DC ihuza ryiza ikoreshwa.
Ibyuma bitagira umuyonga electrode nibyiza DC ihinduka.Niba udafite imashini yo gusudira DC kandi ibyangombwa bisabwa ntabwo biri hejuru cyane, urashobora gukoresha electrode yo mu bwoko bwa Chin-Ca kugirango usudire hamwe na mashini yo gusudira AC.
Gusana gusudira ibice byicyuma mubisanzwe bifata uburyo bwa DC bwihuza.Mugihe cyo gusudira, arc irahagaze neza, spatter ni nto, kandi ubujyakuzimu bwinjira ni buke, ibyo bikaba byujuje gusa ibisabwa kugirango umuvuduko muke wo gusana ibyuma bisudira kugirango ugabanye ibice.
(7) Amazi arc yikora gusudira
Kuzenguruka arc byikora gusudira birashobora gusudira hamwe na AC cyangwa DC amashanyarazi.Yatoranijwe ukurikije ibicuruzwa byo gusudira hamwe nubwoko bwa flux.Niba nikel-manganese ikoreshwa na flux-silicon flux, gusudira amashanyarazi ya DC bigomba gukoreshwa kugirango umutekano wa arc uhagarare kugirango winjire cyane.
(8) Kugereranya hagati yo gusudira AC na gusudira DC
Ugereranije n'amashanyarazi ya AC, amashanyarazi ya DC arashobora gutanga arc ihamye kandi ihererekanya neza.- Iyo arc imaze gutwikwa, arc arc irashobora gukomeza gutwikwa.
Iyo ukoresheje amashanyarazi ya AC, kubera ihinduka ryerekezo ya voltage na voltage, kandi arc igomba kuzimya no kongera gutwikwa inshuro 120 kumasegonda, arc ntishobora gutwika ubudahwema kandi buhamye.
Kubijyanye numuyoboro muto wo gusudira, DC arc igira ingaruka nziza yo guhanagura icyuma cyashongeshejwe kandi gishobora kugena ubunini bwamasaro yo gusudira, kubwibyo birakwiriye cyane gusudira ibice bito.Imbaraga za DC zirakwiriye cyane hejuru no gusudira guhagarikwa kuruta ingufu za AC kuko DC arc ni ngufi.
Ariko rimwe na rimwe arc kuvuza amashanyarazi ya DC nikibazo gikomeye, kandi igisubizo nuguhindura amashanyarazi ya AC.Kuri AC na DC ibyerekezo bibiri bya electrode yagenewe AC cyangwa DC gusudira amashanyarazi, porogaramu nyinshi zo gusudira zikora neza mugihe DC ifite imbaraga.
Mu gusudira intoki arc, imashini zo gusudira AC hamwe nibindi bikoresho byongeweho bihendutse, kandi birashobora kwirinda ingaruka mbi ziterwa ningufu za arc bishoboka.Ariko usibye ibiciro byibikoresho bigabanutse, gusudira hamwe nimbaraga za AC ntabwo bikora neza nkimbaraga za DC.
Amashanyarazi yo gusudira ya Arc (CC) hamwe nibiranga ibintu byamanutse bikwiranye neza nintoki arc gusudira.Ihinduka rya voltage ijyanye nimpinduka zubu irerekana kugabanuka gahoro gahoro uko uburebure bwa arc bwiyongera.Ibi biranga imipaka ntarengwa arc nubwo gusudira kugenzura ubunini bwa pisine yashongeshejwe.
Impinduka zihoraho muburebure bwa arc ntizishobora kwirindwa kuko gusudira kwimura electrode kuruhande rwo gusudira, kandi kwibira biranga ingufu za arc gusudira imbaraga zituma arc ihinduka mugihe cyimpinduka.
