Ukuthuthukisa kanye nomnotho we-orbital welding ekwakhiweni kwamapayipi

Nakuba ubuchwepheshe bokushisela i-orbital bungasha, buyaqhubeka nokuvela, buba namandla futhi buguquguquke, ikakhulukazi ekushiseni kwamapayipi. Ingxoxo noTom Hammer, umshicileli onolwazi e-Axenics eMiddleton, Massachusetts, yembula izindlela eziningi le nqubo engasetshenziswa ngayo ukuxazulula izinkinga eziyinkimbinkimbi zokushisela. Isithombe sihlonipha i-Axenics
I-Orbital welding isineminyaka engaba ngu-60 ikhona, ingeza i-automation kwinqubo ye-GMAW. Kuyindlela ethembekile nesebenzayo yokwenza ama-welds amaningi, nakuba amanye ama-OEM nabakhiqizi bengakawaxhasi amandla ama-orbital welder, bethembele ekushiseleni ngesandla noma kwamanye amasu okuhlanganisa amapayipi ensimbi.
Izimiso zokushisela i-orbital sezineminyaka zikhona, kodwa amandla amashisela amasha e-orbital awenza abe ithuluzi elinamandla kakhulu ebhokisini lamathuluzi le-welder, njengoba abaningi babo manje sebenezici "ezihlakaniphile" ezenza ukuhlela nokuphatha kube lula ngaphambi kokushisela kwangempela. . ● Qala ngezilungiselelo ezisheshayo nezinembayo ukuze uqinisekise ukushisela okungaguquki, okuhlanzekile nokuthembekile.
IThimba Le-Axenics Welding eMiddleton, Massachusetts, umkhiqizi wengxenye yenkontileka, lisiza amakhasimende alo amaningi ukuthi ashiselwe i-orbital uma into efanele yomsebenzi ikhona.
“Nomaphi lapho kwakungenzeka khona, sasifuna ukuqeda isici somuntu ekushiseleni, njengoba abashiseli be-orbital ngokuvamile bekhiqiza izinto zokushisela ezisezingeni elingcono,” kusho uTom Hammer, umshicileli oqeqeshiwe e-Axenics.
Nakuba ukushisela kokuqala kwenziwa eminyakeni engu-2000 edlule, ukushisela kwesimanje kuyinqubo ethuthuke kakhulu eyingxenye ebalulekile yobunye ubuchwepheshe nezinqubo zesimanje. Isibonelo, i-orbital welding ingasetshenziselwa ukudala amasistimu amapayipi ahlanzeke kakhulu asetshenziselwa ukukhiqiza ama-wafers we-semiconductor, asetshenziswa cishe kuwo wonke ama-electronics namuhla.
Elinye lamakhasimende akwa-Axenics liyingxenye yalolu chungechunge lokuhlinzeka. Le nkampani yayibheke umenzi wenkontileka ozosiza ukwandisa umthamo wayo wokukhiqiza, ikakhulukazi ukudala nokufaka amashaneli ensimbi ehlanzekile avumela amagesi ukuthi ageleze ngenqubo yokukhiqiza amapuleti.
Nakuba ama-orbital welder nama-torch clamp turntable etholakala emisebenzini eminingi yamapayipi e-Axenics, awakuvimbeli ukushisela ngesandla ngezikhathi ezithile.
I-Hammer nethimba lokushisela babuyekeze izidingo zekhasimende futhi babuza izindleko nesikhathi:
I-Hammer isebenzisa i-Swagelok M200 kanye ne-Arc Machines Model 207A ezungezisayo yokushisela i-orbital. Bangakwazi ukubamba amashubhu kusuka ku-1/16 "kuya ku-4".
"Ama-Microheads asivumela ukuthi singene ezindaweni okunzima kakhulu ukufinyelela kuzo," kusho yena. “Enye yemikhawulo ye-orbital welding ukuthi sinekhanda elifanele lejoyinti elithile noma cha. Kodwa namuhla, ungakwazi futhi ukugoqa iketango epayipini olishiselayo. Ama-welders angakwazi ukuhamba ngeketango futhi akukho mkhawulo kusayizi wama-welds ongakwenza. Ngibone imishini eminingana ishisela amapayipi angu-20″. Okungenziwa yile mishini namuhla kuyamangaza.”
Uma kucatshangelwa izidingo zokuhlanzeka, inani lama-welds adingekayo kanye nobukhulu obuphansi bodonga, i-orbital welding kuyisinqumo esinengqondo salolu hlobo lwephrojekthi. Uma usebenza ngamapayipi okulawula ukugeleza komoya, i-Hammer ivamise ukushisela insimbi engagqwali engu-316L.
“Khona izinto ziba zimbi kakhulu. Sikhuluma ngokushisela insimbi encane. Nge-welding manual, ukulungiswa okuncane kungabangela ukuphuka kwe-weld. Kungakho sikhetha ukusebenzisa amakhanda okushisela e-orbital, lapho singabhoboza khona ingxenye ngayinye yeshubhu yokushisela futhi siyenze iphelele, ngaphambi kokuthi sifake ingxenye. Sehlisa amandla abe inani elithile ukuze sazi lapho sifaka ingxenye phakathi. kuyoba okuphelele. Ngokuzenzela, uguquko lwenziwa ngeso, futhi uma sinyathela kakhulu, lungadlulela obala.”
Umsebenzi uqukethe amakhulukhulu amashisela okufanele afane. I-orbital welder esetshenziselwa lo msebenzi iqeda ukushisela ngemizuzu emithathu; lapho i-Hammer isebenza ngesivinini esiphezulu, ingakwazi ukushisela ipayipi elifanayo lensimbi engagqwali cishe ngomzuzu.
“Nokho imoto ayinciphisi. Uyigijimisa ngesivinini esikhulu kuqala ekuseni kanti kuze kuphele usuku isagijima ngesivinini esiphezulu,” kusho uHammer. “Ngiqala ukuyigijima ngesivinini esikhulu ekuseni, kodwa ekugcineni ayisebenzi.”
Ukuvimbela ukungcola ekungeneni kwamashubhu ensimbi engagqwali kubalulekile, yingakho ukuthungatha okuhlanzekile okuphezulu embonini ye-semiconductor kuvame ukwenziwa ekamelweni elihlanzekile, indawo elawulwayo evimbela ukungcola ekungeneni endaweni ye-soldering.
I-Hammer isebenzisa i-tungsten elolwe ngaphambili efanayo kumathoshi akhe njenge-Orbiter. Nakuba i-argon ehlanzekile inikeza ukuhlanzwa kwangaphandle nangaphakathi kwe-welding manual kanye ne-orbital, i-orbital welding nayo iyazuza ngokwenza endaweni evalekile. Lapho i-tungsten ikhishwa, i-sheath igcwalisa igesi futhi ivikele i-weld kusuka ku-oxidation. Uma usebenzisa ithoshi eyenziwa ngesandla, igesi inikezwa ohlangothini olulodwa kuphela lwepayipi ukuze lishiselwe.
Ama-welds e-Orbital ngokuvamile ahlanzekile ngoba igesi ivala ipayipi isikhathi eside. Uma ukushisela sekuqalile, i-argon inikeza isivikelo kuze kube yilapho umshiseli enelisekile ukuthi i-weld ibanda ngokwanele.
I-Axenics isebenza nenani lamakhasimende wamandla ahlukile akhiqiza amaseli kaphethiloli e-hydrogen ezinhlobonhlobo zezimoto. Isibonelo, amanye ama-forklift asendlini asebenzisa ama-hydrogen fuel cell ukuze avimbele imikhiqizo ephuma kumakhemikhali ekubhubhiseni ukudla. Okuwukuphela komkhiqizo we-hydrogen fuel cell amanzi.
Elinye lamakhasimende lalinezidingo ezifanayo nezomkhiqizi we-semiconductor, njengokuhlanzeka kwe-weld nokufana. Ufuna ukusebenzisa insimbi engagqwali engu-321 ukushisela odongeni oluncane. Kodwa-ke, umsebenzi wawuhilela ukwakha i-prototype eyindilinga enamabhange amavalvu amaningi, ngalinye liphumele ohlangothini oluhlukile, okushiya indawo encane yokushisela.
I-orbital welder efanelekayo kulo msebenzi izobiza cishe u-$2,000 futhi izosetshenziselwa ukwenza izingxenye ezimbalwa, ngezindleko ezilinganiselwe zama-$250. Akuwenzi umqondo wezezimali. Nokho, i-Hammer inesixazululo esihlanganisa i-welding manual kanye ne-orbital.
"Kulokhu, ngizosebenzisa i-turntable," kusho u-Hammer. “Empeleni kuyafana nokushisela i-orbital, kodwa uzungeza ishubhu, hhayi i-electrode ye-tungsten ezungeze ishubhu. Ngisebenzisa ithoshi lesandla sami, kodwa ngiyakwazi ukulicindezela ku-vise endaweni efanele ukuze ngigcine izandla zami…zikhululekile, ukuze izandla zomuntu zingakwazi ukulimaza i-weld ngenxa yokuthuthumela noma ukuthuthumela. Lokhu kuqeda iningi lephutha lomuntu. Akulungile kangako, njengokushisela i-orbital ngoba akukho endlini, kodwa lolu hlobo lokushisela lungenziwa endaweni ehlanzekile yekamelo ukuze kuqedwe ukungcola.”
Nakuba ubuchwepheshe bokushisela i-orbital buqinisekisa ukuhlanzeka nokuphindaphinda, u-Hammer kanye nabanye abashiseli bayazi ukuthi ubuqotho be-weld bubalulekile ekuvimbeleni isikhathi sokuphumula ngenxa yokukhubazeka kokushisela. Inkampani isebenzisa ukuhlolwa okungabhubhisi (ND) futhi kwesinye isikhathi ukuhlolwa okulimazayo kuwo wonke ama-weld we-orbital.
"Yonke i-weld esiyenzayo iqinisekiswa ngokubukeka," kusho uHammer. Ngemuva kwalokho, ama-welds ahlolwa nge-helium spectrometer. Ngokuya ngokucaciswa noma izidingo zekhasimende, amanye ama-welds ahlolwa nge-radiography. Ukuhlolwa okulimazayo nakho kuyenzeka. ”
Ukuhlola okulimazayo kungase kuhlanganise izivivinyo zamandla aqinile ukuze kutholakale amandla okugcina e-weld. Ukuze ulinganise ukucindezeleka okukhulu i-weld entweni efana ne-316L yensimbi engagqwali engamelana nayo ngaphambi kokwehluleka, ukuhlolwa kwelula futhi kwelule insimbi kuze kufike lapho kuphuka khona.
Amanye ama-welds omthengi wamandla ngezinye izikhathi ahlolwa nge-ultrasonic okungabhubhisi kumashisela wezingxenye ezintathu zamaseli e-hydrogen fuel cell asetshenziswa kweminye imishini yamandla nezimoto.
“Lokhu kuwuvivinyo olubucayi ngoba izinto eziningi esizithumelayo ziqukethe amagesi angaba yingozi. Kubaluleke kakhulu kithina nakumakhasimende ethu ukuthi insimbi engenasici ayinasici futhi ingavuzi,” kusho uHammer.
