9.25 * 1.24mm ASTM A216 316 / 316L Ibyuma bitagira umuyonga byaturutse mu Bushinwa

Iyo gusudira 300 Series ibyuma bitagira umwanda, abashoramari barashobora kuvanaho gusubira inyuma kumuzi yumuyoboro ufunguye mugihe bakomeza ubwiza bwo gusudira.
Gusudira ibyuma bitagira umuyonga hamwe nimiyoboro akenshi bisaba gusubira inyuma hamwe na argon ukoresheje inzira gakondo nka gaze ikingira tungsten arc gusudira (GTAW) hamwe no gusudira ibyuma arc (SMAW).Ariko ikiguzi cya gaze nigihe gitwara kugirango urangize inzira yo gusukura birashobora kuba ingenzi, cyane cyane ko diameter ya pipe n'uburebure byiyongera.

Iyo gusudira 300 Series ibyuma bitagira umwanda, abashoramari barashobora guhindukira muguhindura ibyuma bigufi byumuzingi arc welding (GMAW) aho kuba GTAW cyangwa SMAW gakondo.Iterambere rigufi ryumuzunguruko wa GMAW ritanga kandi imikorere yinyongera, gukora neza no korohereza-gukoresha-inyungu kugirango bifashe kongera inyungu.
Bitewe no kurwanya ruswa n'imbaraga, ibyuma bidafite ingese bikoreshwa mu gukoresha imiyoboro myinshi, harimo peteroli na gaze, peteroli, inganda, na peteroli.Mugihe GTAW isanzwe ikoreshwa mubyuma byinshi bidafite ingese, ifite ibibi bishobora gukemurwa numuyoboro mugufi wahinduwe GMAW.
Ubwa mbere, kubera ikibazo gikomeje kubura abasudira babahanga, kubona inzobere za GTAW nikibazo gikomeje.Icya kabiri, GTAW ntabwo aribwo buryo bwihuse bwo gusudira, bigatuma bigora ibigo byifuza kongera umusaruro kugirango byuzuze ibyo abakiriya bakeneye.Icya gatatu, birasabwa gusubizwa birebire kandi bihenze byimiyoboro idafite ibyuma na pipine.
Isuku ni itangizwa rya gaze mugihe cyo gusudira kugirango ikureho umwanda kandi itange inkunga.Isuku yinyuma irinda uruhande rwinyuma rwa weld kugirango habeho okiside iremereye imbere ya ogisijeni.
Niba inyuma idakingiwe mugihe cyo gusudira imizi, ibi birashobora gutera ibice byibanze.Iyi nenge izwi nka sukari, yitwa rero kuko ubuso imbere muri weld busa cyane nisukari.Kugira ngo wirinde isukari, gusudira ashyiramo gaze ya gaze mu mpera imwe y’umuyoboro, hanyuma ugacomeka impera zumuyoboro hamwe nucomeka.Bakoze kandi umuyaga kurundi ruhande rwumuyoboro.Mubisanzwe kandi bifatirwa hafi yikurikiranya.Nyuma yo koza umuyoboro, bakuyemo kaseti ya kaseti bazengurutse ingingo hanyuma bakomeza gusudira, basubiramo uburyo bwo kwambura no gusudira kugeza gusudira umuzi birangiye.
Blowback irashobora gutwara igihe kinini namafaranga, mubihe bimwe wongeyeho ibihumbi byamadorari kumushinga.Guhindura inzira igezweho ya GMAW inzira yemereye isosiyete gukora imizi idasubira inyuma mumashanyarazi menshi.Kuzenguruka 300 serie idafite ibyuma ni umukandida mwiza, mugihe gusudira hejuru cyane duplex ibyuma bitagira umuyonga bisaba GTAW kubitambuka.
Kugumya kwinjiza ubushyuhe buke bushoboka bifasha kugumya kwangirika kwakazi.Bumwe mu buryo bwo kugabanya ubushyuhe bwinjira ni ukugabanya umubare wogusudira.Ihindurwa ryumuzunguruko mugufi wa GMAW nkibikoresho bigenzurwa (RMD®) ikoresha ibyuma bigenzurwa neza kugirango ihindurwe neza.Ibi byorohereza gusudira kugenzura pisine, bityo kugenzura ubushyuhe bwinjira no kwihuta.Ubushyuhe buke butuma ubwogero bwashongeshejwe guhagarara vuba.
Bitewe no guhererekanya ibyuma bigenzurwa no gukonjesha byihuse pisine, pisine yo gusudira iba idahungabana kandi gaze ikingira isohoka mumatara ya GMAW ugereranije neza.Ibi bituma gukingira gaze guhatirwa binyuze mumuzi yagaragaye, kwirukana ikirere no kwirinda isakaramentu cyangwa okiside munsi yigitereko.Kuberako icyuzi gikonjesha vuba, bisaba igihe gito cyane kugirango gaze igipfuke.
Igeragezwa ryerekanye ko inzira ngufi yahinduwe ya GMAW yujuje ubuziranenge bwa weld mugihe ikomeza kwangirika kwangirika kwibyuma bitagira umwanda nkigihe ukoresha GTAW mugusudira kumizi.
Gusudira imiyoboro ifunguye ukoresheje inzira ngufi yahinduwe ya GMAW irashobora kandi kuzana izindi nyungu mubijyanye numusaruro, imikorere, hamwe namahugurwa yo gusudira.
Guhindura mubikorwa byo gusudira bisaba ibigo kugirango bisubiremo inzira zabyo, ariko iri hinduka rishobora gutanga umusaruro mugihe cyogukoresha amafaranga - kubyaza umusaruro mushya no kuvugurura.
Gusudira imiyoboro ifunguye ukoresheje inzira ngufi yahinduwe ya GMAW irashobora kandi kuzana izindi nyungu mubijyanye numusaruro, imikorere, hamwe namahugurwa yo gusudira.Muri byo harimo:
Kurandura amahirwe yimiyoboro ishyushye bitewe nuburyo bwo gushira ibyuma byinshi kugirango byongere umubyimba wumuyoboro wumuzi.
Kurwanya bihebuje kwimurwa ryinshi kandi rito hagati yimiyoboro.Iyi nzira irashobora gukuraho byoroshye icyuho kigera kuri santimetero 3-16 kubera kohereza ibyuma neza.
Uburebure bwa arc burahoraho bugumaho hatitawe ku kwaguka kwa electrode, yishyura abashoramari baharanira gukomeza uburebure bwagutse.Igenzurwa ryinshi rya pisine hamwe nicyuma gihoraho kigabanya igihe cyamahugurwa kubasudira bashya.
Mugabanye igihe cyo guhindura inzira.Umugozi umwe na gaze ikingira birashobora gukoreshwa mumizi, kuzuza no gukingira inzira.Inzira ya GMAW isunitswe irashobora gukoreshwa mugihe imiyoboro yuzuye kandi igashyirwaho kashe ya gaze ikingira byibuze 80% argon.
Kubikorwa bishaka gukuraho ibyasubijwe inyuma mubyuma bidafite ibyuma, ni ngombwa gukurikiza inama eshanu zingenzi kugirango uhinduke neza inzira igufi ya sisitemu ya GMAW.
Sukura imiyoboro imbere n'inyuma kugirango ukureho umwanda wose.Sukura byibuze santimetero 1 uhereye kumpande zijyanye na brush ya wire yagenewe ibyuma bitagira umwanda.
Koresha silikoni ndende idafite ibyuma byuzuza ibyuma nka 316LSi cyangwa 308LSi.Ibikoresho byinshi bya silicon bifasha guhanagura ubwogero bwo gushonga kandi bukora nka deoxidizer.
Kubisubizo byiza, koresha imvange ya gaz ikingira ikozwe muburyo bwihariye, nka 90% helium, 7.5% argon, na dioxyde de carbone 2,5%.Ubundi buryo ni 98% argon na 2% ya dioxyde de carbone.Utanga gaze yo gusudira arashobora kugira ibindi byifuzo.
Kubisubizo byiza, koresha inama ya cone hamwe numuyoboro wa kanal nozzle kugirango ubone gaze.Nozzle isanzwe hamwe na gaze ya gaze ya diffuzeri itanga ubwishingizi bwiza.
Menya ko gukoresha inzira ngufi ya GMAW yahinduwe (nta gaze yabigenewe) bivamo umubare muto wibitonyanga inyuma ya weld.Ubusanzwe irahagarara nkuko isuderi ikonje kandi yujuje ubuziranenge bwinganda za peteroli, inganda zamashanyarazi na peteroli.
