Txawm hais tias thev naus laus zis vuam orbital tsis yog qhov tshiab, nws txuas ntxiv hloov zuj zus, ua kom muaj zog dua thiab siv tau ntau yam, tshwj xeeb tshaj yog thaum nws los txog rau kev vuam yeeb nkab. Kev xam phaj nrog Tom Hammer, tus kws vuam txuj ci ntawm Axenics hauv Middleton, Massachusetts, qhia txog ntau txoj hauv kev uas cov txheej txheem no tuaj yeem siv los daws cov teeb meem vuam nyuaj. Duab los ntawm Axenics
Kev vuam orbital tau muaj li ntawm 60 xyoo, ntxiv kev ua haujlwm tsis siv neeg rau cov txheej txheem GMAW. Qhov no yog ib txoj hauv kev txhim khu kev qha, siv tau zoo ntawm kev ua ntau yam kev vuam, txawm hais tias qee cov OEMs thiab cov chaw tsim khoom tseem tsis tau siv lub zog ntawm cov neeg vuam orbital, vam khom kev vuam tes lossis lwm txoj hauv kev los koom nrog cov kav hlau.
Cov ntsiab cai ntawm kev vuam orbital tau muaj nyob rau ntau xyoo lawm, tab sis lub peev xwm ntawm cov orbital welders tshiab ua rau lawv yog cov cuab yeej muaj zog dua hauv cov cuab yeej siv vuam, vim tias ntau tus tam sim no muaj cov yam ntxwv "ntse" los ua kom yooj yim dua rau kev teeb tsa thiab ua tiav ua ntej kev vuam tiag tiag. Pib nrog kev hloov kho sai, meej kom ntseeg tau tias cov vuam sib xws, huv si thiab txhim khu kev qha.
Pab neeg ua haujlwm vuam ntawm Axenics hauv Middleton, Massachusetts, yog ib lub tuam txhab tsim khoom siv uas coj ntau tus neeg siv khoom hauv kev vuam orbital yog tias muaj cov khoom zoo rau txoj haujlwm.
"Yog tias ua tau, peb xav tshem tawm cov neeg ua haujlwm vuam, vim tias cov neeg vuam orbital feem ntau tsim cov vuam zoo dua," Tom Hammer, tus kws vuam txawj ntse ntawm Axenics hais.
Txawm hais tias kev vuam thawj zaug tau ua tiav 2000 xyoo dhau los, kev vuam niaj hnub no yog ib qho txheej txheem siab heev uas yog qhov tseem ceeb rau lwm yam thev naus laus zis niaj hnub no thiab cov txheej txheem. Piv txwv li, kev vuam orbital tuaj yeem siv los tsim cov kav dej purity siab uas siv los tsim cov semiconductor wafers uas mus rau hauv txhua yam khoom siv hluav taws xob niaj hnub no.
Ib tug ntawm Axenics cov neeg siv khoom yog ib feem ntawm cov saw hlau no. Nws nrhiav ib lub chaw tsim khoom cog lus los pab nthuav nws lub peev xwm tsim khoom, tshwj xeeb tshaj yog tsim thiab txhim kho cov kav dej stainless hlau huv si uas tso cai rau cov pa roj hla dhau cov txheej txheem tsim wafer.
Txawm hais tias cov chaw vuam orbital thiab cov rooj sib hloov nrog lub clamps torch muaj rau feem ntau cov haujlwm tubular ntawm Axenics, cov no tsis txwv tsis pub vuam tes qee zaum.
Hammer thiab pab pawg vuam tau tshuaj xyuas cov kev xav tau ntawm cov neeg siv khoom thiab nug cov lus nug, suav nrog cov nqi thiab lub sijhawm:
Cov khoom siv rotary enclosed orbital welders uas Hammer siv yog Swagelok M200 thiab Arc Machines Model 207A. Lawv tuaj yeem tuav 1/16 txog 4 nti tubing.
"Cov taub hau me me tso cai rau peb nkag mus rau hauv qhov chaw nruj heev," nws hais. "Ib qho kev txwv ntawm kev vuam orbital yog seb peb puas muaj lub taub hau uas haum rau qhov sib koom ua ke. Tab sis hnub no, koj tuaj yeem qhwv ib txoj saw hlau ncig lub yeeb nkab uas koj vuam. Tus welder tuaj yeem hla lub saw hlau, thiab yeej tsis muaj kev txwv rau qhov loj ntawm cov welds uas koj tuaj yeem ua tau. . Kuv tau pom qee qhov teeb tsa uas ua vuam ntawm 20 ″. Yeeb nkab. Nws yog qhov zoo kawg nkaus uas cov tshuab no tuaj yeem ua hnub no. "
Xav txog qhov yuav tsum tau ua kom huv, tus naj npawb ntawm cov welds xav tau, thiab qhov tuab ntawm phab ntsa nyias, orbital welding yog qhov kev xaiv ntse rau hom phiaj xwm no. Rau kev tswj cov txheej txheem airflow, Hammer feem ntau welds ntawm 316L stainless hlau.
"Thaum ntawd nws maj mam ua heev. Peb tab tom tham txog kev vuam rau ntawm daim ntawv hlau nyias. Nrog kev vuam tes, qhov kev hloov kho me me tuaj yeem ua rau qhov vuam tawg. Yog vim li cas peb thiaj nyiam siv lub taub hau vuam orbital, qhov twg peb tuaj yeem Dial rau hauv txhua qhov ntawm lub raj thiab ua kom nws zoo meej ua ntej muab qhov rau hauv nws. Peb txo lub zog rau ib qho tshwj xeeb kom peb paub tias thaum peb muab qhov rau hauv nws nws yuav zoo meej. Los ntawm tes, qhov kev hloov pauv yog ua los ntawm qhov muag, thiab yog tias peb pedal ntau dhau, nws tuaj yeem nkag mus ncaj qha los ntawm cov khoom siv."
Txoj haujlwm muaj ntau pua qhov vuam uas yuav tsum zoo ib yam. Tus kws vuam orbital siv rau txoj haujlwm no ua qhov vuam hauv peb feeb; thaum Hammer ua haujlwm ntawm qhov ceev tshaj plaws, nws tuaj yeem vuam tib lub raj hlau stainless hlau hauv ib feeb.
"Txawm li cas los xij, lub tshuab tsis qeeb qeeb. Koj khiav nws ntawm qhov ceev tshaj plaws thaum sawv ntxov, thiab thaum kawg ntawm hnub, nws tseem khiav ntawm qhov ceev tshaj plaws," Hammer hais. "Kuv khiav nws ntawm qhov ceev tshaj plaws thaum sawv ntxov, tab sis thaum kawg, qhov ntawd tsis yog qhov teeb meem."
Kev tiv thaiv cov khoom tsis huv kom tsis txhob nkag mus rau hauv cov kav hlau tsis xeb yog qhov tseem ceeb, uas yog vim li cas kev vuam uas muaj kev ntshiab siab hauv kev lag luam semiconductor feem ntau ua nyob rau hauv chav huv, ib puag ncig tswj tau uas tiv thaiv cov khoom tsis huv kom tsis txhob nkag mus rau hauv thaj chaw vuam.
Hammer siv tib lub tungsten uas tau ntse ua ntej hauv nws cov teeb tes uas nws siv hauv Orbiter. Thaum argon ntshiab muab kev ntxuav sab nraud thiab sab hauv hauv kev vuam tes thiab orbital, kev vuam los ntawm cov tshuab orbital kuj tau txais txiaj ntsig los ntawm kev ua tiav hauv qhov chaw kaw. Thaum cov tungsten tawm los, lub plhaub puv nrog roj thiab tiv thaiv qhov vuam los ntawm oxidation. Thaum siv lub teeb tes, cov roj tsuas yog cua tshuab mus rau ib sab ntawm lub raj uas tam sim no raug vuam.
Feem ntau cov orbital welds huv dua vim tias cov roj npog lub raj ntev dua. Thaum pib vuam, argon muab kev tiv thaiv kom txog thaum tus welder paub tseeb tias qhov vuam txias txaus.
Axenics ua haujlwm nrog ntau tus neeg siv khoom siv hluav taws xob lwm yam uas tsim cov roj hydrogen uas siv rau ntau lub tsheb. Piv txwv li, qee lub forklifts uas tsim rau sab hauv tsev siv cov roj hydrogen los tiv thaiv cov tshuaj lom neeg los ntawm kev rhuav tshem cov khoom noj. Tsuas yog cov khoom seem ntawm lub roj hydrogen yog dej.
Ib tug ntawm cov neeg siv khoom muaj ntau yam kev xav tau zoo ib yam li lub tuam txhab tsim khoom semiconductor, xws li kev huv ntawm kev vuam thiab kev sib xws. Nws xav siv 321 stainless hlau rau kev vuam phab ntsa nyias. Txawm li cas los xij, txoj haujlwm yog prototyping lub manifold nrog ntau lub valve banks, txhua tus tawm mus rau hauv ib qho kev taw qhia sib txawv, tawm me ntsis chav rau kev vuam.
Lub tshuab vuam hlau orbital uas tsim nyog rau txoj haujlwm raug nqi li $ 2,000, thiab nws tuaj yeem siv los ua qee qhov me me, nrog rau tus nqi kwv yees li $ 250. Nws tsis muaj txiaj ntsig nyiaj txiag. Txawm li cas los xij, Hammer muaj kev daws teeb meem uas muab cov txheej txheem vuam tes thiab orbital.
"Hauv qhov no, kuv yuav siv lub rooj tig," Hammer hais. "Nws yog qhov ua tau zoo ib yam li lub tshuab vuam orbital, tab sis koj tig lub raj, tsis yog lub tungsten electrode ncig lub raj. Kuv siv kuv lub teeb tes, tab sis kuv tuaj yeem tuav kuv lub teeb rau hauv qhov chaw nrog lub vise Positioned kom nws tsis muaj tes yog li lub vuam yuav tsis raug puas tsuaj los ntawm tib neeg txhais tes co lossis co. Qhov no tshem tawm ntau yam ntawm tib neeg qhov yuam kev. Nws tsis zoo tag nrho li orbital vuam vim nws tsis nyob hauv ib puag ncig kaw, tab sis hom vuam no tuaj yeem ua tiav hauv chav huv si kom tshem tawm cov pa phem.
Txawm hais tias cov thev naus laus zis orbital welding muab kev huv thiab rov ua dua, Hammer thiab nws cov neeg ua haujlwm welders paub tias kev sib txuas zoo yog qhov tseem ceeb rau kev tiv thaiv lub sijhawm tsis ua haujlwm vim yog qhov tsis ua haujlwm ntawm weld. Lub tuam txhab siv kev sim tsis ua puas tsuaj (NDT), thiab qee zaum kev sim ua puas tsuaj, rau txhua qhov orbital welds.
"Txhua qhov vuam uas peb ua yog pom tseeb," Hammer hais. "Tom qab ntawd, cov vuam raug sim nrog lub tshuab ntsuas helium. Nyob ntawm qhov kev qhia tshwj xeeb lossis cov neeg siv khoom xav tau, qee qhov vuam raug sim los ntawm kev siv duab hluav taws xob. Kev sim ua puas tsuaj kuj yog ib qho kev xaiv."
Kev sim ua puas tsuaj yuav suav nrog kev sim lub zog tensile los txiav txim siab qhov kawg tensile lub zog ntawm qhov vuam. Txhawm rau ntsuas qhov kev ntxhov siab siab tshaj plaws uas qhov vuam ntawm cov khoom siv xws li 316L stainless hlau tuaj yeem tiv taus ua ntej ua tsis tiav, qhov kev sim ncab thiab ncab cov hlau mus rau nws qhov tawg.
Cov vuam los ntawm cov neeg siv khoom siv hluav taws xob lwm yam qee zaum raug rau kev sim ultrasonic nondestructive ntawm cov khoom vuam ntawm peb-channel heat exchanger hydrogen roj cell siv hauv cov tshuab hluav taws xob lwm yam thiab tsheb.
"Qhov no yog ib qho kev sim tseem ceeb vim tias feem ntau ntawm cov khoom uas peb xa tuaj muaj cov pa phem uas hla dhau lawv. Nws yog ib qho tseem ceeb heev rau peb thiab peb cov neeg siv khoom tias cov hlau tsis xeb yog qhov zoo tshaj plaws, tsis muaj qhov xau," Hammer hais.
