Gukoresha gazi ikingira nabi cyangwa gazi irashobora kugira ingaruka kumiterere ya weld, ibiciro, numusaruro kuburyo bugaragara. Gukingira gaze birinda ikidendezi cyashongeshejwe cyanduye hanze, bityo rero ni ngombwa guhitamo gaze ibereye akazi.
Kubisubizo byiza, ni ngombwa kumenya imyuka ya gaze na gaze bivanze neza kubikoresho bimwe. Ugomba kandi kumenya inama nkeya zishobora kugufasha guhindura imikorere ya gaze mugikorwa cyawe cyo gusudira, gishobora kuzigama amafaranga.
Amahitamo menshi yo gukingira gaze ya gaz arc welding (GMAW) irashobora gukora akazi. Guhitamo gaze ikwiranye nibikoresho fatizo, uburyo bwo kohereza, hamwe nibipimo byo gusudira birashobora kugufasha kubona byinshi mubushoramari.
Guhitamo gaze ikwiranye nibikoresho fatizo, uburyo bwo kohereza, hamwe nibipimo byo gusudira birashobora kugufasha kubona byinshi mubushoramari bwawe.
Imikorere idahwitse ya gaz
Gutembera neza kwa gaze no gukwirakwiza ni ngombwa kuva igihe arc yo gusudira ikubiswe. Mubisanzwe, ibibazo byo gutembera gaze birahita bigaragara. Urashobora kugira ikibazo cyo gushiraho cyangwa gukomeza arc cyangwa bikagora kubyara umusaruro mwiza.
Usibye ibibazo byubuziranenge, imikorere mibi ya gaz ikingira irashobora kandi gutwara ibiciro mubikorwa. Igipimo cyo gutembera kiri hejuru cyane, kurugero, bivuze ko urimo guta gaze kandi ugakoresha amafaranga menshi mukurinda gaze kurenza uko ubikeneye.
Ibipimo bitemba biri hejuru cyane cyangwa biri hasi cyane birashobora gutera ubwoba, hanyuma bigasaba igihe cyo gukemura ibibazo no gukora. Ibipimo bitemba biri hasi cyane birashobora gutera inenge kubera ko pisine idasudira irinzwe bihagije.
Ingano ya spatter yakozwe mugihe cyo gusudira nayo ifitanye isano na gaze ikingira ikoreshwa. Gutandukana cyane bisobanura igihe kinini namafaranga yakoreshejwe mugusya nyuma.
Nigute Guhitamo Gazi Yikingira
Ibintu byinshi bigena gaze ikingira neza inzira ya GMAW, harimo ubwoko bwibikoresho, ibyuma byuzuza, hamwe nuburyo bwo kohereza.
Ubwoko bwibikoresho.Ibi birashobora kuba ikintu kinini cyo gusuzuma kubisabwa. Kurugero, ibyuma bya karubone na aluminiyumu bifite imiterere itandukanye cyane bityo bisaba imyuka itandukanye yo gukingira kugirango igere kubisubizo byiza. Ugomba kandi kuzirikana ubunini bwibintu mugihe uhitamo gaze ikingira.
Ubwoko bw'ibyuma byuzuza.Icyuma cyuzuza gihuye nibikoresho fatizo, gusobanukirwa rero ibikoresho bigomba kuguha igitekerezo cyiza kubyerekeranye na gaze nziza kubicyuma cyuzuza. Uburyo bwinshi bwo gusudira burimo ibisobanuro birambuye kubyo kuvanga gaze bishobora gukoreshwa hamwe nibyuma byuzuza.
Gukingira gaze neza no gukwirakwiza ni ngombwa kuva igihe gusudira arc gukubitwa. Iki gishushanyo cyerekana urujya n'uruza rw'ibumoso, ruzaba rutwikiriye pisine, hamwe n'umuvurungano uri iburyo.
Uburyo bwo gusudira.Birashobora kuba bigufi-byumuzunguruko, spray-arc, pulsed-arc, cyangwa kwimura isi. Buri buryo bubangikanye neza hamwe na gaze zimwe zikingira. Kurugero, ntugomba na rimwe gukoresha 100 ku ijana argon hamwe nuburyo bwo kohereza spray. Ahubwo, koresha imvange nka 90 ku ijana argon na 10% bya karuboni ya dioxyde. Urwego rwa CO2 muruvange rwa gaze ntirugomba kurenga 25%.
Ibintu byongeweho gusuzuma harimo umuvuduko wurugendo, ubwoko bwokwinjira busabwa kubufatanye, hamwe nibice bikwiye. Ese gusudira ntibihagaze? Niba aribyo, ibyo bizanagira ingaruka kuri gaze ikingira wahisemo.
Gukingira Amahitamo ya GMAW
Argon, helium, CO2, na ogisijeni ni imyuka ikingira cyane ikoreshwa muri GMAW. Buri gaze ifite inyungu nibibi mubisabwa byose. Imyuka imwe ikwiranye neza nizindi kubikoresho bikoreshwa cyane, byaba aluminium, ibyuma byoroheje, ibyuma bya karubone, ibyuma bito bito, cyangwa ibyuma bitagira umwanda.
CO2 na ogisijeni ni imyuka yoroheje, bivuze ko bigira ingaruka kubibera muri pisine. Electron ziyi myuka zifata hamwe na pisine yo gusudira kugirango itange ibintu bitandukanye. Argon na helium ni imyuka ya inert, ntabwo rero ikora hamwe nibikoresho fatizo cyangwa pisine.
Kurugero, CO2 yera itanga ubwimbike bwimbitse cyane, bufite akamaro ko gusudira ibintu byimbitse. Ariko muburyo bwayo butanga umusaruro udakomeye arc hamwe na spatter ugereranije nigihe ivanze nizindi myuka. Niba ubudodo bwiza nubwiza ari ngombwa, imvange ya argon / CO2 irashobora gutanga arc ihagaze neza, kugenzura pisine, no kugabanya spatter.
None, niyihe myuka ihuza neza nibikoresho fatizo bitandukanye?
Aluminium.Ugomba gukoresha argon 100 ku ijana kuri aluminium. Kuvanga argon / helium bikora neza niba ukeneye kwinjira cyane cyangwa umuvuduko wurugendo. Irinde gukoresha gaze ikingira umwuka wa ogisijeni hamwe na aluminium kuko ogisijeni ikunda gukora ubushyuhe kandi ikongeramo urwego rwa okiside.
Icyuma cyoroheje.Urashobora guhuza ibi bikoresho hamwe nuburyo butandukanye bwo gukingira gaze, harimo 100 ku ijana CO2 cyangwa kuvanga CO2 / argon. Mugihe ibikoresho bigenda byiyongera, kongeramo ogisijeni muri gaze ya argon birashobora gufasha kwinjira.
Ibyuma bya karubone.Ibi bikoresho byombi hamwe na 100 ku ijana CO2 cyangwa kuvanga CO2 / argon. Icyuma gike cyane. 98 ku ijana argon / 2 ku ijana ivangwa na gaze ya ogisijeni ikwiranye neza nibi bikoresho.
Gukoresha gazi ikingira nabi cyangwa gazi irashobora guhindura cyane ubwiza bwa weld, ibiciro, numusaruro mubikorwa bya GMAW.
Ibyuma.Argon ivanze na 2 kugeza 5 ku ijana CO2 nibisanzwe. Mugihe ukeneye karbone-nkeya ya karubone muri weld, koresha argon hamwe na ogisijeni 1 kugeza 2%.
Nigute-Inama Zogufasha Gukora Shielding Imikorere
Guhitamo gaze ikingira neza nintambwe yambere igana ku ntsinzi. Kunoza imikorere - kuzigama igihe n'amafaranga - bigusaba kumenya imikorere myiza ishobora gufasha kubungabunga gaze ikingira no guteza imbere ikwirakwizwa rya pisine.
Igipimo cy'Uruzi. Igipimo gikwiye cyo gutemba giterwa nibintu byinshi, harimo umuvuduko wurugendo nubunini bwurusyo ku bikoresho fatizo. Imyuka ya gazi ihindagurika mugihe cyo gusudira mubisanzwe bisobanura umuvuduko wogupima, upimye muri metero kibe kumasaha (CFH), ni muremure cyane, kandi ibyo bishobora gutera ibibazo nkubushake. Niba hari ibipimo byo gusudira bihindutse, ibi birashobora kugira ingaruka kumuvuduko wa gaze.
Kurugero, kongera umuvuduko wo kugaburira insinga nabyo byongera haba mubunini bwumwirondoro weld cyangwa umuvuduko wurugendo, bivuze ko ushobora gukenera umuvuduko mwinshi wa gazi kugirango urebe neza.
Ibikoreshwa.Ibikoresho bikoreshwa mu mbunda ya GMAW, bigizwe na diffuzeri, inama yo guhuza, na nozzle, bigira uruhare runini mu gutuma pisine yo gusudira irindwa neza ikirere. Niba nozzle ifunganye cyane kubisabwa cyangwa niba diffuzeri ihujwe na spatter, gaze ntoya ikingira ishobora kugera kuri pisine. Hitamo ibikoreshwa birwanya kwiyongera kandi utange ubugari buhagije kugirango ubone gaze ihagije. Kandi, menya neza ko inama yo guhuza ikiruhuko ari yo.
Imyuka ya gaze.Gukoresha gaze ikingira amasegonda make mbere yo gukubita arc birashobora gufasha kwemeza ko hari ubwishingizi buhagije. Gukoresha gaze ya gaze irashobora gufasha cyane cyane mugihe cyo gusudira ibinure byimbitse cyangwa ibiti bisaba insinga ndende. Imbere yuzuza gazi mbere yo gutangira irashobora kugufasha kwanga umuvuduko wa gazi, bityo ukabika gaze no kugabanya ibiciro.
Kubungabunga Sisitemu.Mugihe ukoresheje sisitemu ya gaze, kora neza kugirango ufashe kunoza imikorere. Buri kintu cyose gihuza muri sisitemu nisoko ishobora guterwa na gaze, bityo rero ukurikirane amasano yose kugirango umenye neza ko akomeye. Bitabaye ibyo, ushobora gutakaza gaze ikingira utekereza ko igera kuri weld.
Igenzura rya gaze. Witondere gukoresha ibiyobora neza ukurikije ivangwa rya gaze ukoresha. Kuvanga neza ni ngombwa kurinda weld. Gukoresha igenzura ridakwiye kuvanga gaze, cyangwa gukoresha ubwoko butari bwo bwihuza, birashobora kandi kuviramo impungenge z'umutekano. Reba abagenzuzi kenshi kugirango bafashe kwemeza ko bakora neza.
Kuvugurura imbunda.Niba ukoresha imbunda itajyanye n'igihe, reba muri moderi zigezweho zitanga inyungu, nka diametre ntoya y'imbere n'umurongo wa gazi wihariye, bikwemerera gukoresha umuvuduko muke wa gazi. Ibi bifasha kwirinda imvururu muri pisine isudira mugihe no kubungabunga gaze.
