Umuyoboro wo gusudira, voltage na welding ningingo nyamukuru yingufu zerekana ingano ya weld.
1. Umuyoboro wo gusudira
Iyo imiyoboro yo gusudira yiyongereye (ibindi bintu bikomeza kuba bidahindutse), ubujyakuzimu bwinjira nuburebure busigaye bwa weld bwiyongera, kandi ubugari bwo gushonga ntabwo buhinduka cyane (cyangwa kwiyongera gato).Ni ukubera ko:
.Ubujyakuzimu bwimbitse buringaniye no gusudira.
.
.
2. Umuvuduko wa Arc
Nyuma ya voltage ya arc yiyongereye, imbaraga za arc ziriyongera, ubushyuhe bwinjiza bwibikorwa byiyongera, kandi uburebure bwa arc burarambura kandi radiyo yo gukwirakwiza ikiyongera, bityo ubujyakuzimu bugabanuka gato kandi ubugari bwo gushonga bukiyongera.Uburebure busigaye buragabanuka, kubera ko ubugari bwo gushonga bwiyongera, ariko gushonga kwinsinga yo gusudira bigabanuka gato.
3. Umuvuduko wo gusudira
Iyo umuvuduko wo gusudira wiyongereye, ingufu ziragabanuka, kandi ubujyakuzimu bwinjira nubugari bwinjira.Uburebure busigaye nabwo buragabanuka, kubera ko ingano yo gushira ibyuma byinsinga kuri weld kuri buri burebure buringaniye bihwanye n’umuvuduko wo gusudira, kandi ubugari bwo gushonga buringaniye na kare ya kwihuta yo gusudira.
aho U igereranya voltage yo gusudira, Ndi umuyoboro wo gusudira, ikigezweho kigira ingaruka mubwimbitse bwinjira, voltage igira ingaruka mubugari bwo gushonga, ikigezweho ni ingirakamaro gutwika nta gutwika, voltage ifitiye akamaro gake, byombi bikosora imwe muri zo, hindura ikindi kintu gishobora gusudira ingano yikigezweho gifite ingaruka zikomeye kumiterere yo gusudira no gutanga umusaruro.
Umuyoboro wo gusudira ugira uruhare runini mubunini bwinjira.Ibiriho ni bito cyane, arc ntigihungabana, ubujyakuzimu bwinjira ni buto, biroroshye gutera inenge nko kwinjira mu buryo budasobanutse no kwinjiza ibicuruzwa, kandi umusaruro ni muke;Niba ikigezweho ari kinini cyane, gusudira bikunda kugira inenge nko gukata no gutwikwa, kandi icyarimwe bigatera spatter.
Kubwibyo, imiyoboro yo gusudira igomba gutoranywa uko bikwiye, kandi muri rusange irashobora gutoranywa ukurikije formulaire ifatika ukurikije diameter ya electrode, hanyuma igahinduka neza ukurikije imyanya yo gusudira, imiterere ihuriweho, urwego rwo gusudira, uburebure bwa weldment, nibindi.
Umuvuduko wa arc ugenwa nuburebure bwa arc, arc ni ndende, na voltage ya arc ni ndende;Niba arc ari ngufi, imbaraga za arc ziri hasi.Ingano ya voltage ya arc igira ingaruka cyane cyane gushonga ubugari bwa weld.
Arc ntigomba kuba ndende cyane mugihe cyo gusudira, bitabaye ibyo, gutwika arc ntiguhinduka, kongera umuvuduko wicyuma, kandi bizanatera ubwoba muri weld kubera gutera umwuka.Kubwibyo, mugihe cyo gusudira, gerageza gukoresha arc ngufi, kandi mubisanzwe bisaba ko uburebure bwa arc butarenza diameter ya electrode.
Ingano yumuvuduko wo gusudira ifitanye isano itaziguye numusaruro wo gusudira.Kugirango ubone umuvuduko ntarengwa wo gusudira, diameter nini ya electrode nini nu gusudira bigomba gukoreshwa hashingiwe ku kwemeza ubuziranenge, kandi umuvuduko wo gusudira ugomba guhindurwa uko bikwiye ukurikije ibihe byihariye kugira ngo uburebure n'ubugari bwa weld bihamye uko bishoboka.
1. Kuzunguruka inzibacyuho ngufi
Inzibacyuho ngufi muri CO2 arc gusudira niyo ikoreshwa cyane, ikoreshwa cyane cyane kubisahani yoroheje no gusudira umwanya wuzuye, kandi ibipimo byerekana ni arc voltage yo gusudira, umuvuduko wo gusudira, induction yumuzunguruko, umuvuduko wa gazi hamwe nuburebure bwumugozi .
. bike.
(2) Welding circuit induction, umurimo wingenzi wa inductance:
a.Hindura umuvuduko wubwiyongere bwumuzunguruko mugufi wa di / dt, di / dt ni nto cyane kugirango utume ibice binini bisenyuka kugeza igice kinini cyinsinga zo gusudira giturika hanyuma arc ikazimya, kandi di / dt nini cyane kugirango itange a umubare munini wibice bito byicyuma.
b.Hindura igihe cyo gutwika arc hanyuma ugenzure kwinjira mubyuma shingiro.
c .Umuvuduko wo gusudira.Umuvuduko wo gusudira byihuse bizatera impande zombi kumpande zombi, kandi niba umuvuduko wo gusudira utinda cyane, inenge nko gutwika hamwe nuburyo bubi bwo gusudira bizagaragara byoroshye.
d .Icyuka cya gaze giterwa nibintu nkuburinganire bwubwoko bwa plaque, ibisobanuro byo gusudira hamwe nuburyo bukora.Mubisanzwe, umuvuduko wa gazi ni 5-15 L / min mugihe cyo gusudira insinga nziza, na 20-25 L / min mugihe cyo gusudira insinga zibyibushye.
e.Kwagura insinga.Uburebure bukwiye bwo kwagura insinga bugomba kuba inshuro 10-20 z'umurambararo wa wire.Mugihe cyo gusudira, gerageza kugumya kurwego rwa 10-20mm, uburebure bwagutse bwiyongera, imiyoboro yo gusudira iragabanuka, kwinjira mubyuma fatizo bigabanuka, naho ubundi, ibyiyongera byiyongera kandi kwinjira byiyongera.Ninini irwanya insinga yo gusudira, niko bigaragara iyi ngaruka.
f.Amashanyarazi.CO2 arc gusudira muri rusange bifata DC ihindagurika ya polarite, spatter ntoya, arc ihamye ibyuma byinjira byinjira ni binini, kubumba neza, kandi hydrogène yibyuma byo gusudira ni bike.
2. Inzibacyuho nziza.
. kandi iyi nzibacyuho ninzibacyuho nziza.
Mugihe cyo guhinduranya ibice byiza, arc yinjira irakomeye, kandi icyuma fatizo gifite ubujyakuzimu bunini bwinjira, bukwiranye nuburyo bwo gusudira hagati hamwe nubunini.Uburyo bwa DC busubira inyuma bukoreshwa no gusudira ingano nziza.
.Ariko, niba arc ya voltage ari ndende cyane, gusebanya biziyongera cyane, kandi munsi yumuyaga umwe, voltage ya arc igabanuka nkuko diameter yinsinga yo gusudira yiyongera.
Hariho itandukaniro rinini hagati yinzibacyuho ya CO2 ninzibacyuho yindege muri TIG gusudira.Ihinduka ryindege muri TIG gusudira ni axial, mugihe impinduka nziza muri CO2 itari axial kandi haracyari ibyuma bisuka.Mubyongeyeho, indege yinzibacyuho imipaka muri argon arc gusudira ifite ibimenyetso bigaragara biranga ibintu.(cyane cyane gusudira ibyuma bidafite ingese nicyuma cya ferrous), mugihe inzibacyuho nziza itabikora.
3. Ingamba zo kugabanya kumena ibyuma
.Mu karere gatoya, akanya gato
inzibacyuho ni nto, kandi igipimo cyo kugabanuka mukarere kanini kagezweho (agace keza k’inzibacyuho) nako ni nto.
.Nibyiza kugoreka imbunda yo gusudira imbere cyangwa inyuma bitarenze dogere 20.
. uburebure bugomba kugabanywa uko bishoboka kose.
4. Ubwoko butandukanye bwo gukingira imyuka ifite uburyo bwo gusudira butandukanye.
(1) Uburyo bwo gusudira ukoresheje gaze ya CO2 nka gaze ikingira ni CO2 arc gusudira.Imashini igomba gushyirwaho mugutanga ikirere.Kubera ko amazi ya CO2 akuramo ingufu nyinshi zubushyuhe mugihe cya gazi ikomeza, kwaguka kwinshi kwa gaze nyuma yo kwiheba nuwagabanije umuvuduko nabyo bizagabanya ubushyuhe bwa gaze, kugirango hirindwe ubushuhe buri muri gaze ya CO2 gukonja mumasoko ya silinderi kandi umuvuduko ugabanya valve no guhagarika inzira ya gaze, bityo gaze ya CO2 ishyutswe na preheater hagati yumuriro wa silinderi no kugabanya umuvuduko.
.Ubu buryo bwo gusudira bukwiranye no gusudira ibyuma.
