TIG
1.Gusaba :
Gusudira TIG(tungsten argon arc welding) nuburyo bwo gusudira aho Ar yera ikoreshwa nka gaze ikingira kandi tungsten electrode ikoreshwa nka electrode.Umugozi wo gusudira TIG utangwa mumirongo igororotse yuburebure runaka (mubisanzwe lm).Gushiramo gazi ikingira arc gusudira ukoresheje tungsten nziza cyangwa tungsten ikora (thoriated tungsten, cerium tungsten, zirconium tungsten, lanthanum tungsten) nka electrode idashonga, ukoresheje arc hagati ya electrode ya tungsten hamwe nakazi kakozwe kugirango ushongeshe icyuma.Tungsten electrode ntishonga mugihe cyo gusudira kandi ikora nka electrode gusa.Muri icyo gihe, argon cyangwa helium bigaburirwa mu zuba ryaka kugirango birinde.Ibyuma byinyongera nabyo birashobora kongerwaho nkuko ubyifuza.Ku rwego mpuzamahanga nkaGusudira TIG.
2. Ibyiza：
Inyungu nyamukuru yuburyo bwo gusudira TIG nuko ishobora gusudira ibintu byinshi.Harimo ibihangano bifite umubyimba wa 0,6mm no hejuru, ibikoresho birimo ibyuma bivanze, aluminium, magnesium, umuringa hamwe na aliyumu zayo, icyuma gisize icyuma, bronzes zitandukanye, nikel, ifeza, Titanium na gurş.Umwanya nyamukuru wo gusaba ni gusudira ibintu bito kandi biciriritse bikozwe nkibikorwa byumuzi ku bice binini.
3. Icyitonderwa:
A. Gukingira gazi ibisabwa: iyo gusudira biri hagati ya 100-200A, ni 7-12L / min;iyo gusudira iri hagati ya 200-300A, ni 12-15L / min.
B. Uburebure burebure bwa electrode ya tungsten bugomba kuba bugufi bushoboka ugereranije na nozzle, kandi uburebure bwa arc bugomba kugenzurwa muri 1-4mm (2-4mm yo gusudira ibyuma bya karubone; 1-3mm yo gusudira ibyuma bidafite imbaraga; n'ibyuma bidafite ingese).
C. Iyo umuvuduko wumuyaga urenze 1.0m / s, hagomba gufatwa ingamba zidafite umuyaga;witondere guhumeka kugirango wirinde gukomeretsa kubakoresha.
D. Kuraho cyane amavuta, ingese nubushuhe bwumwanya wo gusudira mugihe cyo gusudira.
E. Birasabwa gukoresha amashanyarazi ya DC afite ibintu biranga hanze, kandi tungsten pole ni nziza cyane.
F. Iyo gusudira ibyuma bito bivanze hejuru ya 1.25% Cr, uruhande rwinyuma narwo rugomba kurindwa.
MIG
1.Gusaba ：
MIG gusudirani gushonga pole inert gazi ikingiwe gusudira.Ikoresha Ar hamwe nindi myuka ya inert nka gaze nyamukuru ikingira, harimo gaze ya Ar cyangwa Ar yuzuye ivanze na gaze ya gaze ikora (nka O2 munsi ya 2% cyangwa CO2 munsi ya 5%) kugirango ishonge.Uburyo bwo gusudira bwa arc gusudira.Umugozi wa MIG utangwa muri coil cyangwa coil mubice.Ubu buryo bwo gusudira bukoresha arc yaka hagati yinsinga zikomeza kugaburirwa hamwe nakazi ko gukora nkisoko yubushyuhe, kandi gaze isohoka mumatara nozzle ikoreshwa mukurinda arc gusudira.
2.Ingirakamaro ：
Nibyiza gusudira mumyanya itandukanye, kandi ifite umuvuduko wo gusudira byihuse nigipimo cyo hejuru cyo kubitsa.MIG ikingira arc gusudira irakoreshwa mugusudira ibyuma byinshi byingenzi, harimo ibyuma bya karubone nicyuma kivanze.MIG arc gusudira ikwiranye nicyuma kitagira umwanda, aluminium, magnesium, umuringa, titanium, gutoragura na nikel.Kuzenguruka ibibanza bya Arc nabyo birashobora gukorwa hakoreshejwe ubu buryo bwo gusudira.
3.Icyitonderwa：
A. Igipimo cya gazi ikingira nibyiza 20-25L / min.
B. Uburebure bwa arc bugenzurwa hafi ya 4-6mm.
C. Ingaruka z'umuyaga ntizibereye cyane gusudira.Iyo umuvuduko wumuyaga urenze 0.5m / s, hagomba gufatwa ingamba zidafite umuyaga;witondere guhumeka kugirango wirinde gukomeretsa kubakoresha.
D.Ikoreshwa ryumuvuduko wa arc urashobora kubona spray arc ihamye, cyane cyane ikwiriye gusudira ibyuma bitagira umwanda, isahani yoroheje, gusudira guhagaritse hamwe no gusudira hejuru.
E. Nyamuneka koresha gaze ya Ar + 2% O2 kugirango usudire ultra-low carbone idafite ibyuma, ntukoreshe Ar na CO2 bivanze byo gusudira.
F. Kuraho cyane amavuta, ingese nubushuhe bwumwanya wo gusudira mugihe cyo gusudira.
