Nta tandukaniro riri hagati yuburyo bwuzuye argon arc gusudira na argon arc gusudira.Gusudira kwuzuye arcon arc ikwiranye nu muringoti muto wa diameter ntoya (muri rusange DN60 no munsi, uburebure bwurukuta 4mm), ikigamijwe nukwemeza ubwiza bwumuzi weld hamwe nigaragara.
Iyo diameter ya pipe ari nini kandi ubugari bwurukuta rwinshi, gusudira arcon arc bigomba gukoreshwa nkibishingiro hamwe nogusudira intoki kugirango bitwikire hejuru.Intego yo gusudira intoki ni ukwemeza ubwiza bugaragara bwa diameter nini ya pipe nini yo gusudira intoki, kandi imikorere ikora irarenze iyo gusudira arcon arc.munsi ya argon arc gusudira.
Argon arc gusudira hepfo yo gusudira ikoreshwa mugusudira kurukuta rwamazi yamazi, superheater, economizers, nibindi. Ubwiza bwingingo nibyiza, kandi amanota yo gusudira ari hejuru yicyiciro cya kabiri nyuma yo kugenzura amaradiyo.
Ibyiza bya argon arc gusudira
(1) ubuziranenge
Igihe cyose insinga zikwiye zo gusudira, ibipimo byo gusudira hamwe no kurinda gazi nziza byatoranijwe, umuzi urashobora kwinjira neza, kandi kwinjira ni kimwe, kandi ubuso buringaniye kandi bufite isuku.Nta nenge nko gusudira gusudira, kwinjira bituzuye, kwiheba, imyenge hamwe no gushyiramo slag byoroshye kugaragara mugihe cyo gusudira arc hamwe na electrode rusange.
(2) Gukora neza
Mu cyiciro cya mbere cyo gusudira umuyoboro, intoki ya argon arc gusudira ni guhora arc gusudira.Gusudira electrode arc yamenetse arc gusudira, kubwibyo intoki za argon arc gusudira zishobora kongera imikorere inshuro 2 kugeza kuri 4.Kubera ko gusudira arcon arc bidatanga umusaruro wo gusudira, nta mpamvu yo guhanagura igishishwa no gusana isaro ryo gusudira, kandi umuvuduko uziyongera vuba.Mugice cya kabiri cya arc gusudira hejuru yubuso, igorofa yoroheje kandi itunganijwe neza ya argon arc gusudira hasi ni ingirakamaro cyane hejuru yubuso bwa arc gusudira, bushobora kwemeza guhuza neza hagati yabyo, cyane cyane mu gusudira imiyoboro mito ya diameter, imikorere irarenze gikomeye.
(3) Biroroshye kumenya
Kuzenguruka imizi yo gusudira intoki arc gusudira bigomba gukorwa nabasudira babimenyereye kandi bafite ubuhanga buhanitse.Intoki ya argon arc gusudira ikoreshwa mugushyigikira, kandi abakozi basanzwe bakora imirimo yo gusudira barashobora kuyitoza nyuma yigihe gito cyo kwitoza.
(4) Guhindura ibintu bito
Agace katewe nubushyuhe ni nto cyane mugihe cyo gusudira kwa argon arc, bityo rero guhindura ihinduka ryasizwe ni nto kandi guhangayika gusigaye nabyo ni bito.
Intangiriro
(1) Urugero rwo gusudira
Ubukungu, impumyi ya bundle bundle, urukuta rwamazi hamwe nubushyuhe bwo hasi yubushyuhe bukozwe mubyuma 20, naho umuyoboro mwinshi wubushyuhe bwo hejuru ni 12Cr1MoV.
(2) Kwitegura mbere yo gusudira
Mbere yo gusudira, umunwa wumuyoboro ugomba gutondekwa kuri 30°, kandi ibara ryicyuma rigomba guhanagurwa muri 15mm imbere no hanze yumuyoboro.Ikinyuranyo hagati ya bagenzi babo ni 1 ~ 3mm.Iyo ikinyuranyo nyacyo ari kinini cyane, birakenewe kugaragara hejuru yinzibacyuho kuruhande rwumuyoboro wa mbere.Shiraho ibikoresho byoguhungabanya umuyaga byigihe gito kandi ugenzure cyane umuvuduko wumuyaga ahakorerwa gusudira, kubera ko umuvuduko wumuyaga urenze intera runaka, kandi imyenge yo mu kirere ikabyara byoroshye.
(3) Igikorwa
Koresha intoki ya tungsten argon arc gusudira, imashini yo gusudira ubwayo ifite ibikoresho byifashishwa cyane byo gutwika arc, kandi birashobora gukoreshwa cyane.Kuzimya Arc bitandukanye na electrode arc gusudira.Niba arc yazimye vuba, crac ya crater iroroshye kubaho.Kubwibyo, mugihe cyo gukora, pisine yashongeshejwe igomba kujyanwa kumpande cyangwa icyuma kibyibushye cyane, hanyuma igahindura buhoro buhoro ikidendezi cyashongeshejwe kugirango kizimye buhoro buhoro arc, hanyuma gifunga arc.Gazi ikingira.
Kuri No 20 imiyoboro yicyuma ifite uburebure bwurukuta rwa 3 ~ 4mm, ibikoresho byuzuye birashobora kuba TIGJ50 (kuri 12Cr1MoV, 08CrMoV irashobora gukoreshwa), diameter yinkoni ya tungsten ni 2mm, umuyoboro wo gusudira ni 75 ~ 100A, arc voltage ni 12 ~ 14V, naho umuvuduko wa gazi ikingira ni 8 ~ 10L / min, ubwoko bwamashanyarazi ni DC ihuza neza.
Impamvu ituma argon arc gusudira ishobora gukoreshwa cyane ni ukubera ibyiza bikurikira.
1. Kurinda Argon birashobora gutandukanya ingaruka mbi za ogisijeni, azote, hydrogène, nibindi byo mu kirere kuri arc na pisine yashongeshejwe, kugabanya igihombo cyo gutwika ibintu bivanze, kandi ukabona ingingo zuzuye, zidafite spatter, zifite ubuziranenge bwo gusudira;
2. Gutwika arc ya argon arc gusudira birahagaze, ubushyuhe bwibanze, ubushyuhe bwinkingi ya arc buri hejuru, umusaruro wo gusudira ni mwinshi, akarere gaterwa nubushyuhe ni gake, kandi guhangayika, guhindura no gukurura imyuka yo gusudira ibice ni bito;
3. Argon arc gusudira irakinguye arc gusudira, byoroshye gukora no kwitegereza;
4. Igihombo cya electrode ni gito, uburebure bwa arc buroroshye kububungabunga, kandi nta flux cyangwa coating layer mugihe cyo gusudira, biroroshye rero kumenya imashini no kwikora;
5. Gusudira Argon arc gusudira ibyuma hafi ya byose, cyane cyane ibyuma bimwe na bimwe byangiritse kandi byoroshye okiside byoroshye, nka magnesium, titanium, molybdenum, zirconium, aluminium, nibindi nibindi bivangavanze;
6. Ntabwo igarukira kumwanya wa weldment, kandi irashobora gusudira mumyanya yose.
Ingaruka nyamukuru:
1. Bitewe nubuso bunini bwibasiwe nubushuhe bwa argon arc gusudira, igihangano gikora akenshi gitera deformasiyo, ubukana bwinshi, ibisebe, annealing yaho, guturika, pinholes, kwambara, gushushanya, munsi, cyangwa imbaraga zidahuza hamwe nimbaraga zimbere nyuma yo gusana.inenge nko kwangirika.Cyane cyane mugikorwa cyo gusana utunenge duto two gushora imari, iragaragara hejuru.Mu rwego rwo gusana inenge ziterwa neza, imashini zo gusudira zikonje zirashobora gukoreshwa aho gusudira arcon arc.Bitewe nubushyuhe buke bwimashini zogosha zikonje, ibitagenda neza byo gusudira kwa argon arc biratsindwa neza, kandi ibibazo byo gusana ibyuma bisobanutse neza.
2. Gusudira Argon arc byangiza umubiri wumuntu kuruta gusudira electrode arc.Ubucucike bwa argon arc gusudira ni hejuru, kandi urumuri rwasohotse rurakomeye.Imirasire ya ultraviolet iterwa na arc yayo ni iy'ubusanzwe electrode arc gusudira.Inshuro 5 kugeza 30, nimirasire yimirasire yikubye inshuro 1 kugeza kuri 1.5 yo gusudira electrode arc.Ibikoresho bya ozone byakozwe mugihe cyo gusudira ni byinshi.Noneho, gerageza uhitemo ahantu hafite umwuka mwiza wo kubaka, bitabaye ibyo bizangiza umubiri cyane.
3. Kubyuma bifite aho bishonga no guhumeka byoroshye (nka gurş, amabati, zinc), gusudira biragoye.
