Ibyuma bitagira umwanda ntabwo byanze bikunze bigoye gukorana nabyo, ariko gusudira bisaba kwitondera byumwihariko.Ntabwo ikwirakwiza ubushyuhe nkibyuma byoroheje cyangwa aluminiyumu kandi birashobora gutakaza imbaraga zo kwangirika iyo ubishyushye cyane.Imikorere myiza ifasha kugumya kurwanya ruswa.Ishusho: Amashanyarazi ya Miller
Kurwanya kwangirika kwicyuma kitagira umwanda bituma ihitamo neza muburyo bwinshi bwo gukoresha imiyoboro, harimo ibiryo n'ibinyobwa bisukuye cyane, imiti, imiti y’umuvuduko hamwe n’ibikomoka kuri peteroli.Nyamara, ibi bikoresho ntibikwirakwiza ubushyuhe nkibyuma byoroheje cyangwa aluminiyumu, kandi gusudira bidakwiye birashobora kugabanya kurwanya ruswa.Gukoresha ubushyuhe bwinshi no gukoresha ibyuma byuzuza nabi nibyaha bibiri.
Gukurikiza bimwe mubikorwa byiza byo gusudira ibyuma bidafite ingese birashobora gufasha kunoza ibisubizo no kwemeza ko icyuma gikomeza kwangirika.Byongeye kandi, kuzamura inzira yo gusudira birashobora kongera umusaruro udatanze ubuziranenge.
Iyo gusudira ibyuma bitagira umwanda, guhitamo ibyuma byuzuza ni ngombwa kugenzura ibirimo karubone.Ibyuma byuzuza byifashishwa mu gusudira ibyuma bidafite ingese bigomba kunoza imikorere yo gusudira kandi bikwiriye kubisabwa.
Reba ibyuma byuzuza "L" nka ER308L kuko bitanga urugero rwo hasi rwa karubone ifasha kugumya kwangirika kwangirika kwa karuboni nkeya idafite ibyuma.Gusudira icyuma gike cya karubone hamwe nibyuma byuzuza byongera karubone yibice bya weld, byongera ibyago byo kwangirika.Irinde ibyuma byuzuza "H" kuko bitanga karubone nyinshi kandi bigenewe porogaramu zisaba imbaraga nyinshi mubushyuhe bwo hejuru.
Iyo gusudira ibyuma bidafite ingese, ni ngombwa kandi guhitamo icyuma cyuzuza urwego ruto (nanone ruzwi nkumwanda) wibintu.Ibi nibintu bisigaye mubikoresho fatizo bikoreshwa mugukora ibyuma byuzuza, harimo antimoni, arsenic, fosifore na sulfuru.Birashobora kugira ingaruka zikomeye kubirwanya ibintu.
Kuberako ibyuma bidafite ingese byumva cyane ubushyuhe bwinjiza, gutegura hamwe no guteranya neza bigira uruhare runini mugucunga ubushyuhe kugirango ibintu bibungabunge ibintu.Ibyuho hagati yibice cyangwa bidahuye bisaba itara kuguma ahantu hamwe igihe kirekire, kandi hakenewe ibyuma byinshi byuzuza ibyo byuho.Ibi birashobora gutuma ubushyuhe bwiyongera ahantu hafashwe, bishobora gutera igice gushyuha.Umwanya mubi urashobora kandi kugora guca icyuho no kubona ibyinjira byinjira muri weld.Witondere guhuza ibice nicyuma kitagira umwanda bishoboka.
Ubuziranenge bwibi bikoresho nabwo ni ngombwa cyane.Umubare muto cyane wanduye cyangwa umwanda mubice bisudutse birashobora gutera inenge zigabanya imbaraga nindwara ya ruswa yibicuruzwa byanyuma.Kugira ngo usukure substrate mbere yo gusudira, koresha umuringa wihariye udasanzwe udafite ibyuma bitakoreshejwe ku byuma bya karubone cyangwa aluminium.
Mu byuma bidafite ingese, sensibilisation niyo mpamvu nyamukuru yo gutakaza imbaraga zo kurwanya ruswa.Ibi birashobora kubaho mugihe ubushyuhe bwo gusudira hamwe nigipimo cyo gukonjesha bihindagurika cyane, bikavamo impinduka muri microstructure yibikoresho.
Uku gusudira hanze kumuyoboro wicyuma, gusudira ukoresheje GMAW hamwe nicyuma cyo kubitsa (RMD) udafite imizi yinyuma, birasa mumiterere nubuziranenge kubudodo bukozwe na GTAW inyuma.
Igice cyingenzi cyangirika kwangirika kwicyuma ni okiside ya chromium.Ariko niba karubone iri muri weld iri hejuru cyane, karubide ya chromium iba.Bahambira chromium kandi ikabuza gukora oxyde ya chromium yifuzwa, itanga ibyuma bitagira umwanda birwanya ruswa.Niba nta oxyde ya chromium ihagije, ibikoresho ntibizaba bifite ibyifuzo byifuzwa kandi ruswa irashobora kubaho.
Kwirinda ubukangurambaga biza kumanura ibyuma byuzuza no kugenzura ubushyuhe.Nkuko byavuzwe haruguru, ni ngombwa guhitamo icyuma cyuzuza ibintu birimo karubone nkeya mugihe cyo gusudira ibyuma bitagira umwanda.Nyamara, karubone rimwe na rimwe isabwa gutanga imbaraga kubikorwa bimwe.Kugenzura ubushyuhe ni ngombwa cyane cyane iyo ibyuma bike byuzuza karubone bidakwiye.
Mugabanye igihe gusudira na HAZ biri hejuru yubushyuhe bwo hejuru, mubisanzwe dogere 950 kugeza 1500 Fahrenheit (dogere selisiyusi 500 kugeza 800).Umwanya muto wo kugurisha umara muriki cyiciro, ubushyuhe buke butanga.Buri gihe ugenzure kandi urebe ubushyuhe bwa interpass mugihe cyo kugurisha.
Ubundi buryo ni ugukoresha ibyuma byuzuza ibice bivanga nka titanium na niobium kugirango wirinde gukora karubide ya chromium.Kuberako ibyo bice nabyo bigira ingaruka kumbaraga no gukomera, ibyuma byuzuza ntibishobora gukoreshwa mubisabwa byose.
Imizi yo gusudira tungsten arc gusudira (GTAW) nuburyo gakondo bwo gusudira kumuyoboro wibyuma.Mubisanzwe bisaba gusubira inyuma kwa argon kugirango wirinde okiside kuruhande rwa weld.Ariko rero, gukoresha uburyo bwo gusudira insinga mu miyoboro yicyuma biragenda biba byinshi.Muri ibi bihe, ni ngombwa kumva uburyo imyuka ikingira itandukanye igira ingaruka ku kwangirika kwibintu.
Iyo gusudira ibyuma bidafite ingese ukoresheje gaze arc gusudira (GMAW) gakondo yakoreshaga argon na dioxyde de carbone, imvange ya argon na ogisijeni cyangwa imvange ya gaze eshatu (helium, argon na dioxyde de carbone).Mubisanzwe, iyi mvange irimo ahanini argon cyangwa helium na munsi ya 5% ya dioxyde de carbone kuko karuboni itanga karubone muri pisine isudira kandi byongera ibyago byo gukangurira.Argon nziza ntabwo isabwa GMAW kumyuma idafite ingese.
Umugozi usize ibyuma bidafite ingese wagenewe gukorana nuruvange gakondo rwa 75% argon na 25% ya dioxyde de carbone.Amazi arimo ibintu byabugenewe kugirango birinde kwanduza weld na karubone gaze ikingira.
Mugihe ibikorwa bya GMAW byahindutse, byoroheje gusudira imiyoboro idafite ibyuma.Mugihe porogaramu zimwe zishobora kugikenera inzira ya GTAW, inzira yo gutunganya insinga irashobora gutanga ubuziranenge busa nubushobozi buhanitse mubikorwa byinshi byuma bidafite ingese.
Indangamuntu idafite ibyuma isudira ikozwe na GMAW RMD irasa mubwiza no kugaragara kuri WD ihuye.
Imizi yumuzi ukoresheje inzira ngufi yahinduwe ya GMAW nka Miller igenzurwa nicyuma (RMD) ikuraho gusubira inyuma mubintu bimwe na bimwe bya austenitike idafite ibyuma.Imizi ya RMD irashobora gukurikirwa na pulsed GMAW cyangwa flux-cored arc gusudira kugirango yuzuze kandi ufunge passe, impinduka ibika umwanya namafaranga ugereranije no gukoresha GTAW yasubijwe inyuma, cyane cyane kumiyoboro minini ya diameter.
RMD ikoresha neza igenzurwa ryicyuma kigufi kugirango ikore icyuma gituje, gihamye arc na pisine.Ibi bivamo amahirwe make yo gukonja-gukonjesha cyangwa kudashonga, kugabanuka gake, hamwe nuburyo bwiza bwumuzi.Ihererekanyabubasha ryicyuma naryo ryemeza ko gutonyanga gutonyanga hamwe no kugenzura byoroshye pisine yo gusudira bityo ubushyuhe bwinjira nubwihuta bwo gusudira.
Inzira zidasanzwe zirashobora kuzamura umusaruro wo gusudira.Iyo ukoresheje RMD, umuvuduko wo gusudira urashobora kuva kuri 6 kugeza 12 muri / min.Kuberako inzira itezimbere umusaruro nta gushyushya ibice, bifasha kugumana imiterere no kurwanya ruswa yibyuma.Kugabanya ubushyuhe bwinjiza mubikorwa nabyo bifasha kugenzura imiterere ya substrate.
Iyi progaramu ya GMAW itanga uburebure bwa arc bugufi, arc arc cone, hamwe nubushyuhe buke ugereranije nibisanzwe byatewe.Kuva inzira ifunze, arc drift hamwe nihindagurika intera iri hagati yisonga nigikorwa cyakuweho.Ibi byoroshya imiyoborere ya pisine isudira hamwe kandi idasudira kurubuga.Hanyuma, guhuza GMAW isunitswe kugirango yuzuze kandi hejuru hamwe na RMD kumuzingo wumuzi bituma uburyo bwo gusudira bukorwa hifashishijwe umugozi umwe na gaze imwe, bigabanya igihe cyo guhindura inzira.
