Gusudira ibyuma bitagira umuyonga no kuvoma akenshi bisaba gusubizwa inyuma hamwe na argon mugihe ukoresheje inzira gakondo nka gas tungsten arc welding (GTAW) hamwe nicyuma gikingira icyuma arc (SMAW) .Ariko ikiguzi cya gaze nigihe cyo gushyiraho gahunda yo gusukura kirashobora kuba ingenzi, cyane cyane ko diametre yuburebure n'uburebure bwiyongera.
Mugihe cyo gusudira ibyuma 300 bidafite ingese, abashoramari barashobora kuvanaho gusubira mu miyoboro ifunguye imizi mu guhindukira bava muri gakondo ya GTAW cyangwa SMAW bakajya mu buryo bunoze bwo gusudira, mu gihe bagikomeza kugera ku bwiza bwo gusudira, kugumya kwangirika kwangirika kwangirika, no kubahiriza uburyo bwo gusudira bwifashishwa mu kuzuza umusaruro mu buryo bworoshye kandi bworoshye. .
Bikundwa no kurwanya ruswa nimbaraga zabo, ibyuma bidafite ingese bikoreshwa muburyo bwinshi bwo gukoresha imiyoboro no kuvoma, harimo peteroli na gaze, peteroli na peteroli, mu gihe GTAW yari isanzwe ikoreshwa mubikoresho byinshi bidafite umwanda, ifite ibibi bimwe na bimwe bishobora gukemurwa na GMAW itunganijwe neza.
Ubwa mbere, nkuko ibura ry'abasudira kabuhariwe rikomeje, kubona abakozi bamenyereye GTAW ni ikibazo gikomeje. Icya kabiri, GTAW ntabwo aribwo buryo bwihuse bwo gusudira, bubuza ibigo bishaka kongera umusaruro kugirango byuzuze ibyo abakiriya bakeneye. Icya gatatu, bisaba gufata igihe kinini kandi bihenze cyane byo gusubiza ibyuma bitagira umwanda.
Gusubira inyuma ni iki? Gukuraho ni kwinjiza gaze mugihe cyo gusudira kugirango ikureho umwanda kandi itange inkunga. Isuku yinyuma irinda inyuma ya weld gukora okiside iremereye imbere ya ogisijeni.
Niba inyuma idakingiwe mugihe cyo gusudira kumuzi wumuzi wangiritse, kwangirika kwa substrate bishobora kuvamo. Uku gusenyuka kwitwa saccharification, kwitwa izina rero kuko bivamo ubuso busa nisukari imbere muri weld.Kurinda gushing, gusudira ashyiramo gaze ya gaze mumutwe umwe wumuyoboro hanyuma bagacomeka kumpera yumuyoboro. yakuyemo igice cya kaseti kizengurutse urugingo atangira gusudira, asubiramo inzira yo kwiyambura no gusudira kugeza isaro ryumuzi ryuzuye.
Kuraho gusubira inyuma. Gusubira inyuma birashobora gutwara igihe kinini namafaranga, mubihe bimwe byongeramo ibihumbi byamadorari kumushinga.Ihinduka ryogutezimbere inzira ya GMAW itunganijwe neza yatumye uruganda rwuzuza pasiporo yumuzi utarinze gusubira inyuma mubyuma byinshi bidafite ibyuma.
Kugumya kwinjiza ubushyuhe buke bushoboka bifasha kugumya kurwanya ruswa yibikorwa byakazi.Kugabanya umubare wa passe weld ni inzira imwe yo kugabanya ubushyuhe bwinjira. Kunoza inzira ya GMAW yumuzunguruko mugufi, nka Metal Deposition Deposition (RMD®), koresha uburyo bwogukwirakwiza ibyuma kugirango ugabanye ubushyuhe bwinjira mubisumizi byinjira mumashanyarazi. ze vuba.
Hamwe no guhererekanya ibyuma bigenzurwa no gukonjesha byihuse pisine, pisine yo gusudira ntigihungabana kandi gazi ikingira isiga imbunda ya GMAW isa nkaho idahungabanye.Ibi bituma gazi ikingira inyura mumuzi yuguruye, ikimura ikirere kandi ikarinda isakaramentu cyangwa okiside inyuma yicyuma.Ibyo bitwikiriye gazi bifata igihe gito cyane.
Igeragezwa ryerekanye ko inzira ya GMAW yahinduwe ngufi yujuje ubuziranenge bwa weld mugihe ikomeza kwangirika kwangirika kwibyuma bitagira umwanda nkigihe isaro ryumuzi ryasudwaga na GTAW.
Guhindura inzira yo gusudira bisaba isosiyete kwemeza WPS yayo, ariko ihinduka nkiryo rishobora gutanga igihe kinini kandi kigatwara amafaranga kubikorwa bishya byo gukora no gusana.
Fungura umuyoboro wogusudira ukoresheje uburyo bwihuse bwumuzunguruko wa GMAW utanga inyungu zinyongera mubikorwa, gukora neza no guhugura gusudira.Ibi birimo:
Kurandura ubushobozi bwimiyoboro ishyushye bitewe nubushobozi bwo kubitsa ibyuma byinshi kugirango wongere ubunini bwumuyoboro.
Kwihanganira bihebuje kubihuza no hejuru bidahuye hagati yimiyoboro. Bitewe no kohereza ibyuma byoroshye, inzira irashobora guca icyuho cyoroshye kugeza kuri santimetero 3-16.
Uburebure bwa Arc burahoraho hatitawe ku kwaguka kwa electrode, yishyura abashoramari baharanira gukomeza kwaguka bihoraho.Icyuzi cyoroshye cyo gusudira cyoroshye no guhererekanya ibyuma birashobora kugabanya igihe cyamahugurwa kubasudira bashya.
Mugabanye igihe cyo guhindura inzira.Icyuma kimwe na gaze ikingira birashobora gukoreshwa mumizi, kuzuza no gufata imiyoboro. Inzira ya GMAW isunikwa irashobora gukoreshwa mugihe imiyoboro yuzuye kandi igafatwa byibuze 80% ya gaz ikingira gaze.
Kubikorwa bishaka gukuraho inyuma mugukoresha ibyuma bidafite ingese, ni ngombwa gukurikiza inama eshanu zingenzi kugirango utsinde mugihe uhinduye inzira ngufi ya GMAW yahinduwe.
Sukura imbere n'inyuma y'imiyoboro kugirango ukureho umwanda wose. Koresha umuyonga winsinga wagenewe ibyuma bitagira umwanda kugirango usukure inyuma yumubiri byibuze santimetero 1 uhereye kumpera.
Koresha ibyuma byuzuza ibyuma bitarimo ibyuma birimo silikoni nyinshi, nka 316LSi cyangwa 308LSi.Ibikoresho bya silikoni yo hejuru bifasha pisine yogejwe kandi ikora nka deoxidizer.
Kugirango ukore neza, koresha imvange ya gaz ikingira ikozwe muburyo bwihariye, nka 90% helium, 7.5% argon, na 2,5% ya dioxyde de carbone. Ubundi buryo ni 98% argon na 2% ya dioxyde de carbone. Utanga gaze yo gusudira ashobora kugira ibindi byifuzo.
Kubisubizo byiza, koresha inama yapanze hamwe na nozzle kugirango umuyoboro wumuzi kugirango umenye ubwishingizi bwa gaze.
Menya ko gukoresha inzira ya GMAW yahinduwe mugihe gito udashyigikiwe na gaze itanga umusaruro muke inyuma yinyuma ya weld.Ibisanzwe bigenda neza nkuko isuderi ikonje kandi yujuje ubuziranenge bwibikomoka kuri peteroli, uruganda rukora peteroli na peteroli.
