Ingaruka nziza ya gaze ya Shield ikwiye
Mu 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 kumurongo weld. Ariko, irashobora kandi kugira ingaruka mbi. Ingaruka nziza zo gukoresha gaze ikingira neza nizi zikurikira:
1. Kurinda neza pisine isudira
Kwinjiza neza gaze irinda birashobora gukingira neza pisine isudira okiside cyangwa bikarinda okiside burundu.
2. Kugabanya gutatanya
Kwinjiza neza gaze irinda birashobora kugabanya neza gutemba mugihe cyo gusudira.
3. Imiterere imwe yo gusudira
Kwinjiza neza gazi irinda itera no gukwirakwiza ikidendezi cyo gusudira mugihe cyo gukomera, bikavamo icyerekezo kimwe kandi cyiza cyiza.
4. Kongera ikoreshwa rya laser
Kwinjiza neza gaze irinda birashobora kugabanya neza ingaruka zo gukingira ibyuma byumuyaga wumuyaga cyangwa ibicu bya plasma kuri lazeri, bityo bikongera imikorere ya laser.
5. Kugabanya ububobere bwo gusudira
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.
Ariko,
Gukoresha nabi gaze irinda birashobora kugira ingaruka mbi kuri gusudira. Ingaruka mbi zirimo:
1. Kwangirika kw'icyuma gisudira
Kwinjiza nabi gaze irinda bishobora kuvamo ubudodo bwiza.
2. Kumena no kugabanya imiterere yubukanishi
Guhitamo ubwoko bwa gaze butari bwo bishobora gutuma weld yameneka kandi igabanuka ryimikorere.
3. Kongera okiside 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. 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. Ingaruka ku bujyakuzimu
Kwinjiza gaze ikingira birashobora kugira ingaruka runaka mubwimbike bwa weld, cyane cyane mu gusudira isahani yoroheje, aho ikunda kugabanya ubujyakuzimu.

Ubwoko bwa Gazi Zirinda
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 gukora imiti hamwe na aluminiyumu hamwe nicyuma cya karubone mubushyuhe runaka, bigakora nitide. Ibi birashobora kongera ubukana no kugabanya ubukana bwikidodo, bigira ingaruka mbi kumiterere yubukanishi. Ntabwo rero, gukoresha azote nka gaze ikingira aluminiyumu hamwe n’icyuma cya karuboni. Ku rundi ruhande, azote irashobora kubyitwaramo ibyuma bitagira umwanda, ikora nitride yongerera imbaraga imbaraga zifatanije. Azote rero irashobora gukoreshwa nka gaze ikingira 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 nimiti 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. Gaz 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 bwo Kumenyekanisha Gazi
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.

Amahame yo guhitamo uburyo bwo kumenyekanisha gaze ya Shield
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.
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 Kumenyekanisha Gazi
1. Umurongo ugororotse Weld
Niba igicuruzwa cyo gusudira kigororotse kigororotse, nkuko bigaragara ku gishushanyo cya 3, kandi iboneza hamwe birimo ibibuno, guhuza lap, gusudira, cyangwa gusudira, uburyo bwatoranijwe kuri ubu bwoko bwibicuruzwa ni uburyo bwo guhanagura impande zombi. Igishushanyo 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. Birasaba 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.
