Nibihe bintu nyamukuru bigira ingaruka ku gusudira kwa electrode?

Ibipimo byo gusudira bya electrode arc gusudira cyane cyane harimo diameter ya electrode, gusudira, amashanyarazi ya arc, umubare wibikoresho byo gusudira, ubwoko bwamashanyarazi nubwoko bwa polarite, nibindi.

1. Guhitamo diameter ya electrode

Guhitamo diameter ya electrode ahanini biterwa nibintu nkubunini bwa weldment, ubwoko bwurugingo, umwanya weld hamwe nurwego rwo gusudira.Hashingiwe ku kutagira ingaruka ku bwiza bwo gusudira, kugirango tunoze umusaruro wumurimo, mubisanzwe bakunda guhitamo electrode nini ya diameter.

Kubice byo gusudira bifite ubunini bunini, hagomba gukoreshwa electrode nini ya diameter.Kuri gusudira neza, diameter ya electrode yakoreshejwe irashobora kuba nini;gusudira guhagaritse, diameter ya electrode yakoreshejwe ntabwo irenze mm 5;gusudira gutambitse no gusudira hejuru, diameter ya electrode yakoreshejwe muri rusange ntabwo irenze mm 4.Kubijyanye no gusudira ibice byinshi hamwe na parike ibangikanye, kugirango hirindwe ko habaho inenge zuzuye zuzuye, electrode ya mm 3.2 ya diametre igomba gukoreshwa murwego rwa mbere rwo gusudira.Mubihe bisanzwe, diameter ya electrode irashobora gutoranywa ukurikije ubunini bwa weldment (nkuko bigaragara mumeza TQ-1).

2. Guhitamo imiyoboro yo gusudira

Ingano yimyanda yo gusudira igira uruhare runini muburyo bwo gusudira no gutanga umusaruro.Niba ikigezweho ari gito cyane, arc ntigihinduka, kandi biroroshye gutera inenge nko gushyiramo slag no kwinjira bituzuye, kandi umusaruro ni muke;niba ikigezweho ari kinini cyane, inenge nka undercut hamwe no gutwikwa birashoboka, kandi spatter iriyongera.

Kubwibyo, mugihe cyo gusudira hamwe na electrode arc gusudira, imiyoboro yo gusudira igomba kuba ikwiye.Ingano yumuyaga wo gusudira igenwa ahanini nibintu nkubwoko bwa electrode, diameter ya electrode, uburebure bwa weldment, ubwoko bwahujwe, umwanya weld hamwe nu rwego rwo gusudira, muribyo bintu byingenzi ni diameter ya electrode hamwe nu mwanya wa weld.Iyo ukoresheje ibyuma rusange byubaka ibyuma bya electrode, isano iri hagati yo gusudira hamwe na diameter ya electrode irashobora gutoranywa na formulaire ifatika: I = kd

Muri formula, mpagarariye gusudira (A);byerekana diameter ya electrode (mm);

k yerekana coefficient ijyanye na diameter ya electrode (reba Imbonerahamwe TQ-2 yo guhitamo).

Mubyongeyeho, umwanya uhagaze weld uratandukanye, kandi ubunini bwumudozi wo gusudira nabwo buratandukanye.Mubisanzwe, ikigezweho mu gusudira guhagaritse bigomba kuba munsi ya 15% ~ 20% ugereranije no gusudira neza;ikigezweho cyo gusudira gutambitse no gusudira hejuru ni 10% ~ 15% munsi ugereranije no gusudira neza.Ubunini bwo gusudira ni bunini, kandi umupaka wo hejuru wubu urafatwa.

Amashanyarazi ya elegitoronike ya elegitoronike hamwe nibintu byinshi bivangavanze muri rusange bifite ingufu nyinshi zirwanya amashanyarazi, coeffisiyeti nini yo kwagura amashyuza, umuyaga mwinshi mugihe cyo gusudira, kandi electrode ikunda gutukura, bigatuma igifuniko kigwa igihe kitaragera, bikagira ingaruka kumiterere yo gusudira, kandi ibintu bivangavanze bigatwikwa; byinshi, bityo gusudira Ibiriho bigabanuka uko bikwiye.

3. Guhitamo voltage ya arc

Umuvuduko wa arc ugenwa nuburebure bwa arc.Niba arc ari ndende, voltage ya arc ni ndende;niba arc ari ngufi, imbaraga za arc ziri hasi.Mubikorwa byo gusudira, niba arc ari ndende cyane, arc izashya itajegajega, spatter yiyongera, kwinjira bizagabanuka, kandi umwuka wo hanze uzatera abantu byoroshye, bitera inenge nka pore.Kubwibyo, uburebure bwa arc busabwa kuba munsi cyangwa bingana na diameter ya electrode, ni ukuvuga gusudira arc ngufi.Iyo ukoresheje aside electrode yo gusudira, kugirango ushushe igice kigomba gusudwa cyangwa kugabanya ubushyuhe bwikidendezi cyashongeshejwe, rimwe na rimwe arc irambuye gato kugirango isudwe, ibyo bita gusudira birebire.

4. Guhitamo umubare wumurongo wo gusudira

Kuzenguruka ibice byinshi bikoreshwa mugusudira arc ya plaque yo hagati kandi yuzuye.Ibice byinshi ni ingirakamaro mu kunoza plastike no gukomera kwa weld, cyane cyane ku mfuruka ikonje.Ariko, birakenewe gukumira ingaruka mbi ziterwa no gushyushya ingingo no kwagura akarere katewe nubushyuhe.Mubyongeyeho, kwiyongera k'umubare w'ibyiciro bikunda kongera deformisiyo yo gusudira.Kubwibyo, bigomba kugenwa no kubitekerezaho byuzuye.

5. Guhitamo ubwoko bw'amashanyarazi na polarite

Amashanyarazi ya DC afite arc ihamye, spatter ntoya kandi nziza yo gusudira.Mubisanzwe bikoreshwa mugusudira ibyingenzi byo gusudira cyangwa amasahani manini hamwe nuburyo bunini bukomeye.

Mu bindi bihe, ugomba kubanza gutekereza gukoresha imashini yo gusudira AC, kubera ko imashini yo gusudira AC ifite imiterere yoroshye, igiciro gito, kandi yoroshye gukoresha no kubungabunga kuruta imashini yo gusudira DC.Guhitamo polarite ishingiye kumiterere ya electrode n'ibiranga gusudira.Ubushyuhe bwa anode muri arc burenze ubushyuhe bwa cathode, kandi polarisi zitandukanye zikoreshwa mugusudira gusudira.
