Gusudira ni inzira aho ibikoresho by'ibikorwa bigomba gusudwa (kimwe cyangwa bitandukanye) bihujwe no gushyushya cyangwa igitutu cyangwa byombi, kandi hamwe cyangwa bituzuyemo ibikoresho, ku buryo ibikoresho by'ibikorwa byahujwe hagati ya atome kugira ngo bibe a ihuriro.Ni izihe ngingo z'ingenzi kandi zimenyeshwagusudira ibyuma?
Niki electrode ikoreshwa mugusudira ibyuma bidafite ingese？
1.Icyuma cya electrode idafite ibyuma irashobora kugabanywa muri chromium idafite ibyuma bya electrode na chromium-nikel ibyuma bitagira ibyuma.Ubu bwoko bubiri bwa electrode bujuje ubuziranenge bwigihugu bugomba gusuzumwa hakurikijwe GB / T983-2012.
2.Icyuma cya chromium kitagira ibyuma gifite imbaraga zo kurwanya ruswa (aside oxyde, aside organic, cavitation) irwanya ubushyuhe no kurwanya ruswa.Mubisanzwe byatoranijwe nkibikoresho byibikoresho byamashanyarazi, inganda zikora imiti, peteroli nibindi.Nyamara, ubushobozi bwo gusudira bwa chromium butagira ibyuma muri rusange burakennye, kandi bugomba kwitondera kwishyura uburyo bwo gusudira, uburyo bwo kuvura ubushyuhe no guhitamo electrode ikwiye.
3.Cromium-nikel ibyuma bitagira umuyonga electrode ifite imbaraga zo kurwanya ruswa no kurwanya okiside, kandi ikoreshwa cyane mubikorwa bya shimi, ifumbire, peteroli, hamwe n’imashini zivura.Mu rwego rwo kwirinda kwangirika kw’imiterere bitewe no gushyuha, umuyoboro wo gusudira ntugomba kuba munini cyane, uri munsi ya 20% ugereranije n’ibyuma bya electrode ya karubone. Arc ntigomba kuba ndende cyane, imikoranire ikonje vuba, gusudira kwamasaro ni bikwiye.
Ingingo yo gusudira ibyuma bitamenyeshejwe
Amashanyarazi afite vertical vertical ibiranga byemewe, kandi polarite nziza ikoreshwa kuri DC (insinga yo gusudira ihujwe na pole mbi)
1.Bisanzwe birakwiriye gusudira ibyuma bito bito munsi ya 6mm.Ifite ibiranga imiterere nziza yo gusudira no guhindura ibintu bito.
2.Gasi ikingira ni argon ifite ubwiza bwa 99,99%.Iyo umuyoboro wo gusudira ari 50 ~ 150A, umuvuduko wa gazi ya argon ni 8 ~ 10L / min, iyo umuyaga ari 150 ~ 250A, umuvuduko wa gaze ya argon ni 12 ~ 15L / min.
3.Uburebure bugaragara bwa tungsten electrode iva muri gaz nozzle nibyiza 4 ~ 5mm.Ni 2 ~ 3mm ahantu hamwe harinda gukingirwa nko gusudira kuzuza, na 5 ~ 6mm ahantu ahantu hahanamye.Intera kuva nozzle kumurimo muri rusange ntabwo irenze 15mm.
4. Kugirango wirinde gusudira, niba hari ingese n’amavuta ku bice byo gusudira, bigomba gusukurwa.
5. Uburebure bwo gusudira arc nibyiza 2 ~ 4mm mugihe cyo gusudira ibyuma bisanzwe, na 1 ~ 3mm mugihe cyo gusudira ibyuma bitagira umwanda.Niba ari ndende cyane, ingaruka zo kurinda ntizizaba nziza.
6. Iyo buto-buto, kugirango wirinde inyuma yisaro yo hepfo ya weld kuba okiside, inyuma nayo igomba gukingirwa na gaze.
7. Kugirango gazi ya argon irinde neza pisine yo gusudira no koroshya imikorere yo gusudira, umurongo wo hagati wa tungsten electrode hamwe nakazi kakozwe aho gusudira bigomba muri rusange kugumana inguni ya 80 ~ 85 °, nu mfuruka hagati ya wuzuza insinga hamwe nubuso bwakazi bigomba kuba bito bishoboka.Muri rusange, ni nka 10 °.
8. Umuyaga udahumeka no guhumeka.Ahari umuyaga, nyamuneka fata ingamba zo guhagarika urushundura, kandi ufate ingamba zikwiye zo guhumeka mumazu.
