1. Ibyingenzi bya tekinike ya argontungsten arc gusudira
1.1 Guhitamo tungsten argon arc gusudira imashini hamwe na polarite
TIG irashobora kugabanywamo DC na AC pulses.DC pulse TIG ikoreshwa cyane cyane mu gusudira ibyuma, ibyuma byoroheje, ibyuma birwanya ubushyuhe, nibindi, naho AC pulse TIG ikoreshwa cyane cyane mu gusudira ibyuma byoroheje nka aluminium, magnesium, umuringa hamwe n’ibivange.Impanuka zombi za AC na DC zikoresha amashanyarazi afite ibintu bitonyanga bikabije, kandi gusudira TIG kumpapuro zidafite ingese mubisanzwe zikoresha DC nziza.
1.2 Ibyingenzi bya tekiniki yintoki ya argon tungsten arc gusudira
1.2.1
Hariho ubwoko bubiri bwa arc gutwika: kudahuza no guhuza imiyoboro ngufi ya arc gutwika.Electrode yambere ntabwo ihuye nakazi kayo kandi irakwiriye gusudira DC na AC, mugihe iyanyuma ikwiriye gusudira DC gusa.Niba uburyo bwumuzunguruko bugufi bwakoreshejwe mugukubita arc, arc ntigomba gutangirira muburyo bwo gusudira, kuko biroroshye gutera tungsten kwinjiza cyangwa guhuza nakazi, arc ntishobora guhita ihagarara, kandi arc iroroshye winjire mubikoresho fatizo, bityo plaque ya arc igomba gukoreshwa.Shira isahani y'umuringa itukura iruhande rwa arc, ubanze utangire arc kuri yo, hanyuma wimuke mugice cyo gusudira nyuma yumutwe wa tungsten ushyutswe nubushyuhe runaka.Mubikorwa nyabyo, TIG mubisanzwe ikoresha arc itangira kugirango itangire arc.Munsi yimikorere ya pulse, gaze ya argon ionis kugirango itangire arc.
1.2.2
Mugihe cyo gusudira tack, insinga yo gusudira igomba kuba yoroheje kuruta insinga zisanzwe.Kubera ubushyuhe buke no gukonjesha byihuse mugihe cyo gusudira ahantu, arc igumaho igihe kirekire, kuburyo byoroshye gutwika.Mugihe ukora gusudira ahantu, insinga yo gusudira igomba gushyirwa kumwanya wo gusudira, kandi arc irahagaze Noneho wimuke kuri wire yo gusudira, hanyuma uhagarike arc byihuse nyuma yuko insinga yo gusudira ishonga kandi igahuza ibyuma fatizo kumpande zombi.
1.2.3 Gusudira bisanzwe
Iyo TIG isanzwe ikoreshwa mugusudira impapuro zidafite ingese, icyuma gifata agaciro gake, ariko mugihe ikigezweho kiri munsi ya 20A, drift arc iroroshye kubaho, kandi ubushyuhe bwikibanza cya cathode buri hejuru cyane, bizatera ubushyuhe. ahantu ho gusudira no kutangiza imyuka ya elegitoronike, bikavamo umwanya wa cathode uhora usimbuka kandi biragoye gukomeza kugurisha bisanzwe.Iyo TIG isunitswe ikoreshwa, impinga yumuyaga irashobora gutuma arc ihagarara neza, icyerekezo ni cyiza, kandi icyuma cyibanze cyoroshye gushonga no gukora, kandi inzinguzingo zirasimburana kugirango habeho iterambere ryogukora neza.gusudira.
2. Isesengura ryo gusudira kumpapuro zidafite ingese
Imiterere yumubiri nuburyo bwurupapuro rwicyuma rutagira umwanda bigira ingaruka kumiterere ya weld.Urupapuro rwicyuma rudafite ubushyuhe buto hamwe nuburinganire bunini bwo kwagura umurongo.Iyo ubushyuhe bwo gusudira buhindutse vuba, ubushyuhe bwumuriro butangwa ni bunini, kandi biroroshye gutera gutwika, kugabanuka no guhindagurika.Kuzenguruka impapuro zidafite ingese ahanini bifata gusudira neza.Ikidendezi gishongeshejwe cyane cyane nimbaraga za arc, uburemere bwicyuma cya pisine gishongeshejwe hamwe nuburinganire bwubuso bwicyuma cya pisine.Iyo ingano, ubwiza nubugari bwashongeshejwe byicyuma gishongeshejwe gihoraho, ubujyakuzimu bwa pisine yashongeshejwe biterwa na arc.Ingano, ubujyakuzimu bwimbaraga nimbaraga za arc bifitanye isano nu gusudira, kandi ubugari bwa fusion bugenwa na voltage ya arc.
Ninini yubunini bwa pisine yashongeshejwe, nubunini bwubuso.Iyo impagarara zubuso zidashobora kuringaniza imbaraga za arc hamwe nuburemere bwicyuma cya pisine cyashongeshejwe, bizatera pisine yashongeshejwe, kandi bizashyuha kandi bikonje mugace mugihe cyo gusudira, bitera gusudira guhangayikishwa na Inhomogeneous stress, mugihe igihe kirekire cyo kugabanuka kwicyuma gisudira gitera guhangayikishwa nuruhande rwisahani yoroheje kurenza agaciro runaka, bizatanga ihinduka rikomeye ryimiterere kandi bigira ingaruka kumiterere yibikorwa.Muburyo bumwe bwo gusudira hamwe nuburyo bwo gutunganya ibintu, imiterere itandukanye ya tungsten electrode ikoreshwa mukugabanya ubushyuhe bwinjira kumasuderi, bishobora gukemura ibibazo byo gutwikwa no gutwikwa.
3. Gukoresha intoki ya tungsten argon arc gusudira mumashanyarazi yo gusudira
3.1 Ihame ryo gusudira
Argon tungsten arc gusudira nuburyo bwo gufungura arc gusudira hamwe arc ihamye hamwe nubushyuhe bukabije.Kurinda gaze ya inert (gaze ya argon), pisine yo gusudira ni nziza kandi ubwiza bwikidodo ni bwiza.Ariko, mugihe cyo gusudira ibyuma bidafite ingese, cyane cyane ibyuma bya austenitike, inyuma yinyuma nayo igomba gukingirwa, bitabaye ibyo hazabaho okiside ikomeye, izagira ingaruka kumikorere yo gusudira no gukora.
3.2 Ibiranga gusudira
Kuzenguruka impapuro zidafite ingese zifite ibintu bikurikira:
1) Ubushyuhe bwumuriro wurupapuro rwicyuma ni bibi, kandi biroroshye gutwika muburyo butaziguye.
2) Nta nsinga yo gusudira isabwa mugihe cyo gusudira, kandi ibyuma fatizo byahujwe neza.
Kubwibyo, ubwiza bwibikoresho byo gusudira bidafite ingese bifitanye isano rya bugufi nkibikorwa, ibikoresho, ibikoresho, uburyo bwubwubatsi, ibidukikije byo hanze no kugerageza mugihe cyo gusudira.
Mubikorwa byo gusudira kumpapuro zicyuma zidafite ingese, ibikoreshwa byo gusudira ntibisabwa, ariko ibisabwa kubikoresho bikurikira ni byinshi cyane: kimwe ni ubuziranenge bwa gaze ya argon, umuvuduko wigihe nigihe cyo gutembera kwa argon, naho ubundi ni tungsten electrode.
1) Argon
Argon ni gaze ya inert, kandi ntabwo byoroshye kubyitwaramo nibindi bikoresho byuma na gaze.Bitewe n'ingaruka zo gukonjesha ikirere cyayo, akarere gaterwa nubushyuhe bwa weld ni nto, kandi deformisiyo yo gusudira ni nto.Nibintu byiza cyane byo gukingira gaze ya argon tungsten arc gusudira.Ubuziranenge bwa argon bugomba kuba burenze 99,99%.Argon ikoreshwa cyane cyane kurinda neza ikidendezi cyashongeshejwe, kubuza umwuka kwangirika muri pisine yashongeshejwe no gutera okiside mugihe cyo gusudira, kandi mugihe kimwe cyo gutandukanya neza aho gusudira nikirere, kugirango agace kegeranye karinzwe kandi imikorere yo gusudira iratera imbere.
2) Tungsten electrode
Ubuso bwa electrode ya tungsten bugomba kuba bworoshye, kandi impera igomba gukarishya hamwe nibitekerezo byiza.Muri ubu buryo, kwihuta kwinshi arc gutwika nibyiza, gutuza kwa arc nibyiza, ubujyakuzimu bwimbitse ni ndende, pisine yashongeshejwe irashobora kuguma ihagaze neza, ikidodo cyasudwe kiba cyarakozwe neza, kandi ubwiza bwo gusudira nibyiza.Niba ubuso bwa electrode ya tungsten bwatwitswe cyangwa hakaba hari inenge nkimyanda ihumanya, ibice, hamwe nuduce twagabanutse hejuru, bizagorana gutangira arc yumurongo mwinshi mugihe cyo gusudira, arc izaba idahungabana, arc izakora gutembera, ikidendezi gishongeshejwe kiratatana, ubuso buzaguka, ubujyakuzimu bwinjira buzaba buke, kandi icyuma gisudira kizangirika.Imiterere mibi, ubuziranenge bwo gusudira.
4 Umwanzuro
1) Guhagarara kwa argon tungsten arc gusudira nibyiza, kandi imiterere ya tungsten electrode itandukanye igira uruhare runini muburyo bwo gusudira kumpapuro zicyuma.
)
3) Gukoresha uburyo bwiza bwo gusudira birashobora gukumira neza inenge zo gusudira.
