Ingaruka za gaze ikingira muri Laser Welding
Niki Gazi Ikingira Ikwiye Kubona?
In gusudira laser, guhitamo gaze ikingira birashobora kugira ingaruka zikomeye kumiterere, ubwiza, ubujyakuzimu, n'ubugari bw'ubudodo.
Mubenshi mubibazo byinshi, kwinjiza gaze ikingira bigira ingaruka nziza kumasuderi mugihe gukoresha nabi gaze kurinda bishobora kugira ingaruka mbi kubudozi.
Ingaruka zikwiye kandi zidakwiye zo gukoresha gaze irinda ni izi zikurikira:
Gukoresha neza
Gukoresha nabi
1. Kurinda neza Ikidendezi
Kwinjiza neza gaze irinda birashobora gukingira neza pisine isudira okiside cyangwa bikarinda okiside burundu.
1. Kwangirika kwa Weld
Kwinjiza nabi gaze irinda bishobora kuvamo ubudodo bwiza.
2. Kugabanuka kwa Spattering
Kwinjiza neza gaze irinda birashobora kugabanya neza gutemba mugihe cyo gusudira.
2. Kumena no Kugabanya Ibikoresho bya Mikoranike
Guhitamo ubwoko bwa gaze butari bwo bishobora gutuma weld yameneka kandi igabanuka ryimikorere.
3. Imiterere imwe ya Weld Seam
Kwinjiza neza gazi irinda itera no gukwirakwiza ikidendezi cyo gusudira mugihe cyo gukomera, bikavamo icyerekezo kimwe kandi cyiza cyiza.
3. Kwiyongera kwa Oxidation cyangwa Kwivanga
Guhitamo umuvuduko wa gazi itariyo, yaba hejuru cyane cyangwa hasi cyane, birashobora gutuma okiside yiyongera kumasuderi. Irashobora kandi guteza imvururu zikomeye ku cyuma gishongeshejwe, bikaviramo gusenyuka cyangwa gushingwa kutaringaniye.
4. Kongera ikoreshwa rya Laser
Gutangiza neza gaze irinda birashobora kugabanya neza ingaruka zo gukingira ibyuma byumuyaga wumuyaga cyangwa ibicu bya plasma kuri lazeri, bityo byongera imikorere ya laser.
4. Kurinda bidahagije cyangwa Ingaruka mbi
Guhitamo uburyo bwo kumenyekanisha gaze nabi birashobora gutuma habaho uburinzi budahagije bwo gusudira cyangwa gushobora no kugira ingaruka mbi kumiterere ya weld.
5. Kugabanya ubukana bwa Weld
Kwinjiza neza gazi irinda birashobora kugabanya neza imiterere ya poro ya gaz mukibumbano. Muguhitamo ubwoko bwa gaze ikwiye, umuvuduko, nuburyo bwo gutangiza, ibisubizo byiza birashobora kugerwaho.
5. Ingaruka Zimbitse
Kwinjiza gaze ikingira birashobora kugira ingaruka runaka mubwimbike bwa weld, cyane cyane mu gusudira isahani yoroheje, aho ikunda kugabanya ubujyakuzimu.
Ubwoko butandukanye bwa gaze ikingira
Imyuka ikoreshwa cyane mu gusudira laser ni azote (N2), argon (Ar), na helium (He). Iyi myuka ifite imiterere itandukanye yumubiri nubumashini, bivamo ingaruka zitandukanye kumurongo weld.
1. Azote (N2)
N2 ifite ingufu zingana ionisiyoneri, iruta Ar na munsi ya He. Mubikorwa bya lazeri, ionise kurwego ruciriritse, bigabanya neza imiterere yibicu bya plasma no kongera ikoreshwa rya laser. Ariko, azote irashobora kwitwara neza hamwe na aluminiyumu hamwe nicyuma cya karubone mubushyuhe runaka, bigakora nitide. Ibi birashobora kongera ubunebwe no kugabanya ubukana bwikidodo, bikagira ingaruka mbi kumiterere yubukanishi. Ntabwo rero, gukoresha azote nka gaze ikingira aluminiyumu na karuboni yo gusudira. Ku rundi ruhande, azote irashobora gukora hamwe nicyuma kitagira umwanda, ikora nitride yongerera imbaraga imbaraga zifatanije. Azote rero irashobora gukoreshwa nka gaze irinda gusudira ibyuma bitagira umwanda.
2. Argon Gas (Ar)
Gazi ya Argon ifite ingufu nkeya cyane ionisiyoneri, bikavamo urwego rwo hejuru rwa ionisation munsi ya laser. Ibi ntabwo ari byiza kugenzura imiterere yibicu bya plasma kandi birashobora kugira ingaruka runaka kumikoreshereze myiza ya laseri. Nyamara, argon ifite reaction nke cyane kandi ntibishoboka ko ihura nubushakashatsi hamwe nibyuma bisanzwe. Byongeye kandi, argon irahendutse. Byongeye kandi, kubera ubwinshi bwacyo, argon irohama hejuru ya pisine, itanga uburinzi bwiza kuri pisine. Kubwibyo, irashobora gukoreshwa nka gaze isanzwe ikingira.
3. Gazi ya Helium (He)
Gazi ya Helium ifite ingufu nyinshi za ionisiyoneri, biganisha ku ntera yo hasi cyane ya ionisiyoneri ikorwa na laser. Iremera kugenzura neza igicu cya plasma, kandi laseri irashobora gukorana neza nicyuma. Byongeye kandi, helium ifite reaction nke cyane kandi ntishobora guhita ihura n’imiti, bityo ikaba gaze nziza yo gukingira. Nyamara, igiciro cya helium ni kinini, kubwibyo ntabwo gikoreshwa mugukora ibicuruzwa byinshi. Bikunze gukoreshwa mubushakashatsi bwa siyanse cyangwa kubicuruzwa byongerewe agaciro.
Uburyo bubiri bwo gukoresha gaze ikingira
Kugeza ubu, hari uburyo bubiri bwingenzi bwo kumenyekanisha gaze ikingira: kuruhande rwa axis ihuha hamwe na gaze yo gukingira coaxial, nkuko bigaragara ku gishushanyo cya 1 n’ishusho ya 2.
Igishushanyo 1: Off-axis Kuruhande rwa gaz ya Shielding
Igishushanyo 2: Umwuka wa Coaxial Shielding
Guhitamo hagati yuburyo bubiri bivuza biterwa nibitekerezo bitandukanye.
Muri rusange, birasabwa gukoresha uburyo bwo guhumeka kuruhande rwa gaz.
Nigute ushobora guhitamo gaze ikingira?
Ubwa mbere, ni ngombwa gusobanura ko ijambo "okiside" yo gusudira ari imvugo ikoreshwa. Mubyigisho, bivuga kwangirika kwubwiza bwa weld bitewe nubushakashatsi bwimiti hagati yicyuma gisudira nibintu byangiza mukirere, nka ogisijeni, azote, na hydrogen.
Kurinda okiside ya weld ikubiyemo kugabanya cyangwa kwirinda guhura hagati yibi bice byangiza nicyuma cyo hejuru cyo hejuru. Iyi miterere yubushyuhe bwo hejuru ntabwo ikubiyemo icyuma cya pisine cyashongeshejwe gusa ahubwo kirimo nigihe cyose uhereye igihe icyuma gisuduye gishonga kugeza pisine ikomera kandi ubushyuhe bwayo bukagabanuka munsi yurwego runaka.
Uburyo bwo gusudira
Kurugero, mugusudira kwa titanium, iyo ubushyuhe buri hejuru ya 300 ° C, kwihuta kwa hydrogène bibaho; hejuru ya 450 ° C, kwinjiza ogisijeni byihuse bibaho; no hejuru ya 600 ° C, kwihuta kwa azote bibaho.
Kubwibyo rero, birakenewe kurinda neza titanium alloy weld mugihe cyicyiciro iyo ikomera kandi ubushyuhe bwayo bukagabanuka munsi ya 300 ° C kugirango birinde okiside. Ukurikije ibisobanuro byavuzwe haruguru, biragaragara ko gaze ikingira ikingira ikeneye kurinda umutekano muri pisine yo gusudira gusa mugihe gikwiye ariko no mukarere gakomeye konyine. Niyo mpamvu, uburyo bwo guhanagura kuruhande rwerekanwe ku gishushanyo cya 1 burahitamo muri rusange kuko butanga uburyo bwagutse bwo kurinda ugereranije nuburyo bwo gukingira coaxial bwerekanwe ku gishushanyo cya 2, cyane cyane mukarere gakomeye gusa ka weld.
Nyamara, kubicuruzwa bimwe byihariye, guhitamo uburyo bigomba gukorwa hashingiwe kumiterere yibicuruzwa no kuboneza hamwe.
Guhitamo Byihariye Uburyo bwo Kwinjiza Gazi Irinda
1. Umurongo ugororotse Weld
Niba igicuruzwa cyo gusudira giteye neza, nkuko bigaragara ku gishushanyo cya 3, kandi iboneza rihuriweho ririmo guhuza utubuto, guhuza lap, gusudira kwuzuye, cyangwa gusudira, uburyo bwatoranijwe kuri ubu bwoko bwibicuruzwa ni uburyo bwo guhanagura kuruhande rwerekanwe ku gishushanyo 1.
Igishushanyo 3: Umurongo ugororotse Weld
2. Umubumbe ufunze Geometrie Weld
Nkuko bigaragara ku gishushanyo cya 4, gusudira muri ubu bwoko bwibicuruzwa bifite imiterere ya planari ifunze, nkumuzingi, uruziga, cyangwa imirongo myinshi. Ibishushanyo bifatanyijemo bishobora gushiramo ibibuno, guhuza lap, cyangwa gusudira. Kuri ubu bwoko bwibicuruzwa, uburyo bwatoranijwe ni ugukoresha gaze ya coaxial ikingira igaragara ku gishushanyo cya 2.
Igishushanyo 4: Umubumbe wa Geometrie Weld
Guhitamo gazi ikingira planari ifunze geometrike yo gusudira bigira ingaruka kuburyo butaziguye ubwiza, imikorere, nigiciro cyumusaruro wo gusudira. Ariko, kubera ibikoresho bitandukanye byo gusudira, guhitamo gaze yo gusudira biragoye mubikorwa byo gusudira. Bisaba gutekereza cyane kubikoresho byo gusudira, uburyo bwo gusudira, imyanya yo gusudira, hamwe nibisubizo byo gusudira. Guhitamo gaze yo gusudira neza irashobora kugenwa hifashishijwe ibizamini byo gusudira kugirango ugere kubisubizo byiza.

Ibibazo
- Mu gusudira laser, gukingira gaze nikintu gikomeye gikoreshwa mukurinda agace kegereye kwanduza ikirere. Umuyoboro mwinshi wa lazeri ikoreshwa muri ubu bwoko bwo gusudira ubyara ubushyuhe butari buke, bigakora icyuzi gishongeshejwe cyicyuma.
Gazi ya inert ikoreshwa mugukingira ikidendezi cyashongeshejwe mugihe cyo gusudira imashini zogosha. Iyo ibikoresho bimwe bisuditswe, okiside yo hejuru ntishobora gutekerezwa. Nyamara, kubisabwa byinshi, helium, argon, azote, nizindi myuka ikoreshwa nkuburinzi. Ibikurikira Reka turebe impamvu imashini zo gusudira laser zikenera gaze ikingira iyo gusudira.
Mu gusudira lazeri, gaze ikingira izagira ingaruka kumiterere yo gusudira, ubwiza bwa weld, kwinjira muri weld, n'ubugari bwa fusion. Mu bihe byinshi, guhuha gaze ikingira bizagira ingaruka nziza kuri weld.
- Imvange ya Argon-HeliumImvange ya Argon-Helium: mubisanzwe birasabwa kubikoresho byinshi byo gusudira aluminium laser bitewe nurwego rwa laser. Imvange ya Argon-Oxygene: irashobora gutanga imikorere myiza kandi yemewe yo gusudira.
- Imyuka ikoreshwa mugushushanya no gukoresha lazeri ya gaz niyi ikurikira: dioxyde de carbone (CO2), helium-neon (H na Ne), na azote (N).
Ikibazo cyose kijyanye no gusudira intoki?
