Txawm hais tias orbital vuam thev naus laus zis tsis yog tshiab, nws txuas ntxiv hloov zuj zus, ua kom muaj zog thiab ntau yam, tshwj xeeb tshaj yog thaum nws los txog rau cov yeeb nkab vuam.Kev sib tham nrog Tom Hammer, tus kws tshaj lij welder ntawm Axenics hauv Middleton, Massachusetts, qhia ntau txoj hauv kev uas cov txheej txheem no tuaj yeem siv los daws cov teeb meem vuam nyuaj.Image courtesy of Axenics
Orbital vuam tau nyob ib ncig ntawm 60 xyoo, ntxiv automation rau GMAW txheej txheem.Qhov no yog ib tug txhim khu kev qha, tswv yim txoj kev ntawm kev ua ntau yam welds, txawm hais tias ib co OEMs thiab manufacturers tseem tsis tau siv lub hwj chim ntawm orbital welders, cia siab rau tes welding los yog lwm yam tswv yim los koom hlau tubing.
Cov hauv paus ntsiab lus ntawm orbital welding tau nyob ib ncig ntawm kaum xyoo, tab sis lub peev xwm ntawm cov tshiab orbital welders ua rau lawv muaj zog dua cov cuab yeej hauv cov cuab yeej siv vuam, vim muaj ntau tam sim no muaj "ntse" nta kom yooj yim rau kev pab cuam thiab txheej txheem ua ntej welding tiag tiag.Pib nrog ceev, meej hloov kho kom zoo ib yam, ntshiab thiab txhim khu kev qha weldments.
Axenics 'pab neeg ntawm welders nyob rau hauv Middleton, Massachusetts, yog ib daim ntawv cog lus cov chaw tsim tshuaj paus uas coj ntau ntawm nws cov neeg muas zaub nyob rau hauv orbital welding xyaum yog hais tias muaj yog muaj nyob rau hauv txoj hauj lwm.
Tom Hammer, tus kws tshaj lij welder ntawm Axenics hais tias "Qhov twg ua tau, peb xav tshem tawm tib neeg lub hauv paus hauv kev vuam, raws li orbital welds feem ntau tsim cov vuam zoo dua,"
Txawm hais tias qhov ntxov tshaj plaws welding tau ua tiav 2000 xyoo dhau los, kev vuam niaj hnub yog cov txheej txheem siab heev uas yog ib qho tseem ceeb rau lwm cov thev naus laus zis niaj hnub thiab cov txheej txheem.Piv txwv li, orbital vuam siv tau los tsim cov kav dej siab huv siv los tsim cov khoom siv hluav taws xob uas nkag mus rau hauv cov khoom siv hluav taws xob niaj hnub no.
Ib qho ntawm Axenics 'cov neeg siv khoom yog ib feem ntawm cov khoom siv no.Nws nrhiav cov chaw tsim khoom cog lus los pab nthuav nws lub peev xwm ntau lawm, tshwj xeeb tsim thiab txhim kho cov hlau tsis huv huv uas tso cai rau cov pa roj kom dhau los ntawm cov txheej txheem wafer fabrication.
Thaum orbital welding units thiab cov rooj teb nrog lub teeb nyem yog muaj rau feem ntau cov hauj lwm tubular ntawm Axenics, cov no tsis txwv qee zaus tes vuam.
Rauj thiab pab pawg vuam tau tshuaj xyuas cov neeg siv khoom xav tau thiab nug cov lus nug, suav nrog cov nqi thiab sijhawm:
Cov rotary enclosed orbital welders siv rauj yog Swagelok M200 thiab Arc Machine Model 207A.Lawv muaj peev xwm tuav 1/16 mus rau 4 nti tubing.
"Microheads tso cai rau peb nkag mus rau hauv qhov chaw nruj heev," nws hais. "Ib qho kev txwv ntawm orbital vuam yog seb peb puas muaj lub taub hau uas haum rau ib qho kev sib koom ua ke.Tab sis niaj hnub no, koj tuaj yeem qhwv ib txoj hlua ncig ntawm cov yeeb nkab uas koj tab tom vuam.Tus welder tuaj yeem hla cov saw hlau, thiab nws tsis muaj kev txwv rau qhov loj ntawm cov welds koj tuaj yeem ua..Kuv tau pom qee qhov teeb tsa uas ua vuam ntawm 20 ".Yeeb.Nws yog qhov zoo siab uas cov tshuab no tuaj yeem ua tau niaj hnub no. "
Xav txog cov kev xav tau purity, tus naj npawb ntawm cov welds xav tau, thiab cov phab ntsa nyias nyias, orbital welding yog ib qho kev xaiv ntse rau hom phiaj no.Rau cov txheej txheem airflow tswj kav kav dej, Rauj nquag welds ntawm 316L stainless hlau.
“Nov yog thaum nws tau txais kev hloov maj mam.Peb tab tom tham txog vuam ntawm daim ntawv nyias hlau.Nrog txhais tes vuam, qhov hloov me ntsis tuaj yeem tawg qhov vuam.Tias yog vim li cas peb nyiam siv lub taub hau orbital weld, qhov twg peb tuaj yeem Dial hauv txhua feem ntawm lub raj thiab ua kom nws zoo meej ua ntej muab qhov tso rau hauv.Peb tig lub hwj chim mus rau ib qho nyiaj tshwj xeeb kom peb paub tias thaum peb muab ib feem rau hauv nws yuav zoo tag nrho.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 hauj lwm muaj ntau pua ntawm welds uas yuav tsum zoo tib yam.Lub orbital welder siv rau txoj hauj lwm no ua rau ib tug weld nyob rau hauv peb feeb;Thaum Hammer ua tau zoo tshaj plaws, nws tuaj yeem txuas tib lub raj stainless hlau hauv li ib feeb.
“Txawm li cas los xij, lub tshuab tsis qeeb.Koj khiav nws ntawm max ceev thawj yam thaum sawv ntxov, thiab thaum kawg ntawm hnub, nws tseem khiav ntawm max ceev, "Raws li hais."Kuv khiav nws ntawm qhov ceev ceev thawj zaug thaum sawv ntxov, tab sis thaum kawg, qhov ntawd tsis yog li ntawd."
Tiv thaiv kom tsis txhob muaj kab mob nkag mus rau hauv stainless hlau tubing yog qhov tseem ceeb, uas yog vim li cas high-purity soldering nyob rau hauv semiconductor kev lag luam feem ntau ua nyob rau hauv ib tug huv chav tsev, ib puag ncig tswj uas tiv thaiv cov kab mob los ntawm soldered cheeb tsam.
Rauj siv tib lub pre-sharpened tungsten nyob rau hauv nws txhais tes torches uas nws siv nyob rau hauv lub Orbiter.While ntshiab argon muab sab nraud thiab sab hauv purging nyob rau hauv phau ntawv thiab orbital vuam, vuam los ntawm orbital machines kuj tau txais txiaj ntsig los ntawm kev ua nyob rau hauv ib qho chaw kaw.Thaum lub tungsten tawm los, lub plhaub ntim nrog cov pa roj carbon monoxide thiab tiv thaiv ib sab ntawm tes. ntawm lub raj uas tam sim no tau welded.
Orbital welds feem ntau yog huv dua vim tias cov roj npog lub raj ntev dua.Thaum vuam pib, argon muab kev tiv thaiv kom txog rau thaum tus welder paub tseeb tias qhov vuam txias txaus.
Axenics ua haujlwm nrog ntau lwm cov neeg siv khoom siv hluav taws xob uas tsim cov roj hluav taws xob uas siv hluav taws xob ntau lub tsheb.Piv txwv li, qee lub forklifts ua rau siv sab hauv tsev cia siab rau hydrogen roj hlwb los tiv thaiv cov khoom siv tshuaj lom neeg los ntawm kev rhuav tshem cov khoom noj khoom haus.Qhov tsuas yog cov khoom ntawm hydrogen roj cell yog dej.
Ib qho ntawm cov neeg siv khoom muaj ntau qhov kev xav tau zoo ib yam li cov chaw tsim khoom lag luam semiconductor, xws li vuam purity thiab sib xws.Nws xav siv 321 stainless hlau rau nyias phab ntsa vuam.Txawm li cas los xij, kev ua haujlwm yog prototyping ib manifold nrog ntau lub tsev txhab nyiaj valve, txhua tus protruding nyob rau hauv ib tug sib txawv kev taw qhia, tawm me ntsis chav rau vuam.
Lub orbital welder tsim nyog rau txoj haujlwm raug nqi kwv yees li $ 2,000, thiab nws tuaj yeem siv los ua cov khoom me me, nrog rau kwv yees tus nqi ntawm $ 250.Nws tsis ua rau muaj kev txiav txim siab nyiaj txiag.Txawm li cas los xij, rauj muaj cov kev daws teeb meem uas sib txuas nrog phau ntawv thiab orbital vuam cov tswv yim.
"Hauv qhov no, kuv yuav siv lub rooj teb," Hammer hais tias. "Nws yog qhov ua tau zoo ib yam li kev siv lub tshuab orbital, tab sis koj tab tom tig lub raj, tsis yog tungsten electrode nyob ib ncig ntawm lub raj.Kuv siv kuv txhais tes taws, tab sis kuv muaj peev xwm tuav kuv lub teeb nyob rau hauv qhov chaw nrog ib tug vise Positioned yog li nws yog hands-free ces lub weld yuav tsis puas los ntawm tib neeg tes tuav los yog co.Qhov no tshem tawm ntau yam ntawm tib neeg yuam kev.Nws tsis zoo li orbital vuam vim nws tsis nyob hauv ib puag ncig, tab sis hom vuam no tuaj yeem ua tiav hauv chav huv huv kom tshem tawm cov kab mob. "
Thaum orbital vuam tshuab muaj purity thiab repeatability, Hammer thiab nws cov phooj ywg welders paub hais tias weld kev ncaj ncees yog ib qho tseem ceeb rau kev tiv thaiv downtime vim weld tsis ua hauj lwm.Lub tuam txhab siv tsis-destructive xeem (NDT), thiab tej zaum kev puas tsuaj kuaj, rau tag nrho cov orbital welds.
Hammer hais tias "Txhua qhov weld peb tsim tau pom tseeb," "Tom qab ntawd, cov welds raug kuaj nrog lub helium spectrometer.Raws li qhov tshwj xeeb lossis cov neeg siv khoom xav tau, qee qhov welds raug kuaj ntsuas hluav taws xob.Kev kuaj kev puas tsuaj kuj yog ib qho kev xaiv. "
Kev ntsuas kev puas tsuaj tuaj yeem suav nrog kev ntsuas lub zog tensile los txiav txim siab qhov kawg tensile lub zog ntawm lub vuam.To ntsuas qhov siab tshaj plaws kev ntxhov siab ntawm cov khoom siv xws li 316L stainless hlau tuaj yeem tiv taus ua ntej tsis ua hauj lwm, qhov kev sim ncab thiab ncab cov hlau mus rau nws qhov tawg.
Welds los ntawm lwm lub zog cov neeg siv khoom yog qee zaum raug kuaj ultrasonic nondestructive ntawm cov khoom siv weldments ntawm peb-channel tshav kub exchanger hydrogen roj hlwb siv nyob rau hauv lwm lub zog machinery thiab tsheb.
"Qhov no yog qhov kev sim tseem ceeb vim tias feem ntau ntawm cov khoom uas peb xa khoom tuaj yeem muaj cov pa phem dhau los ntawm lawv.Nws yog ib qho tseem ceeb heev rau peb thiab peb cov neeg muas zaub uas stainless hlau yog flawless, nrog xoom cov ntsiab lus, ”hais Hammer.
