Gazi ya Metal Arc Welding (GMAW): "Ihitamo ryatoranijwe" ryo gusudira ubuziranenge

Gase ya gaz arc gusudira (GMAW) ikoresha gaze ya inert cyangwa gaze ikora nkuburyo bwo gukingira kugirango itandukanya ingaruka zumwuka kuri pisine yashongeshejwe. Igaragaza ubuziranenge bwo gusudira hamwe nuburyo bwiza bwo gusudira. Igabanijwemo ubwoko bubiri bwingenzi: gusudira tungsten inert gasudira (TIG) na CO₂ gaze ikingira gusudira (MIG / MAG), bikwiranye nibikoresho bitandukanye hamwe na ssenariyo.

1. Tungsten Inert Gas Welding (TIG Welding): "Impuguke" mu gusudira neza

Gusudira TIG ikoresha gaze ya argon (ubuziranenge ≥99.99%) nka gaze ikingira. Ashyushya igihangano unyuze muri arc hagati ya tungsten electrode nakazi, kandi irashobora gukorwa hamwe cyangwa idafite insinga zuzuza (gusudira autogenous). Irakwiriye gusudira neza ibikoresho bya okiside byoroshye nk'ibyuma bitagira umwanda, aluminiyumu, hamwe na titanium, nk'ibigize ikirere, imiyoboro y'umuvuduko, n'ibikoresho by'ubuvuzi.

Ingingo z'ingenzi zikorwa:

Guhitamo Tungsten Electrode: Koresha electrode ya tungsten ikoreshwa mugusudira ibyuma bitagira umwanda na electrode nziza ya tungsten yo gusudira aluminiyumu. Hindura diameter ya tungsten electrode ukurikije ikigezweho (urugero, 2.4mm tungsten electrode ya 100-150A). Igenzura uburebure bwa electrode ya tungsten kuri 2-5mm kugirango wirinde guhura ninsinga zuzuza, zishobora gutera tungsten electrode.

Igenzura rya gazi: Hindura imigendekere ya argon ukurikije ubunini bwakazi: 8-10L / min kumasahani yoroheje (≤3mm) na 12-15L / min kubisahani binini (> 5mm). Ongera igihe cyo kurinda argon amasegonda 3-5 mugihe urangije arc kugirango wirinde ubushyuhe bwo hejuru bwa weld.

5mm). Ongera igihe cyo kurinda argon amasegonda 3-5 mugihe urangije arc kugirango wirinde ubushyuhe bwo hejuru bwa weld.

Tekinike Yuzuza Tekinike: Ongeramo insinga zuzuza imbere yicyuzi gishongeshejwe, wirinde guhura na arc. Igenzura umuvuduko wo gusudira kuri 5-10cm / min kugirango urebe neza ko pisine yashongeshejwe kandi wirinde kubura inenge.

CO₂ gasi ikingira gusudira ikoresha CO₂ cyangwa gaze ivanze ya CO₂ na argon nkuburyo bukingira, hamwe no kugaburira insinga zikoresha. Ifite ubushobozi bwo gusudira cyane (inshuro 2-3 ziva kuri SMAW) hamwe nigiciro gito, bigatuma ibera umusaruro mwinshi wibyuma bya karuboni nkeya nicyuma giciriritse, nkimodoka zitwara ibinyabiziga, ibikoresho byo munzu, hamwe no gukora kontineri.

Ingingo z'ingenzi zikorwa:

Guhuza Parameter: Huza cyane umuyaga na voltage (urugero, 22-24V kuri 150A ikigezweho). Igenzura uburebure bwagutse bwa 10-15mm (hafi inshuro 5-10 z'umurambararo); kwaguka birebire birashobora gutera umuvuduko ukabije, mugihe gito cyane gishobora gutwika nozzle.

Inguni yo gusudira: Emera uburyo bwo gusudira ibumoso (kwimura itara ryo gusudira uhereye iburyo ujya ibumoso). Komeza inguni ya 15-25 ° hagati yumuriro wo gusudira hamwe nakazi kugirango ukore neza kuri pisine yashongeshejwe na gaze. Koresha ingabo yumuyaga mugihe umuvuduko wumuyaga urenze 2m / s kugirango wirinde gaze ikingira, ishobora gutera ubwoba.
