Kunyange zvazvo tekinoroji yeorbital welding isiri itsva, inoramba ichishanduka, ichiwedzera kuva nesimba uye kuita zvinhu zvakasiyana-siyana, kunyanya kana iri nyaya yekunama pombi.Bvunzurudzo yakaitwa naTom Hammer, ane hunyanzvi hwekuwelda weAxenics muMiddleton, Massachusetts, inoratidza nzira dzakawanda nzira idzi dzinogona kushandiswa kugadzirisa matambudziko akaomarara.
Orbital welding yave iripo kwemakore anenge 60, ichiwedzera otomatiki kuGMAW process.Iyi inzira yakavimbika, inoshanda yekuita akawanda welds, kunyangwe mamwe maOEM nevagadziri vasati vashandisa simba re orbital welders, vachivimba nemaoko welding kana mamwe maitiro ekubatanidza simbi tubing.
Misimboti ye orbital welding yave iripo kwemakumi emakore, asi kugona kwevatsva orbital welder kunoita kuti ive chishandiso chine simba mune welder's toolkit, sezvo vazhinji vava ne "smart" maficha ekuita kuti zvive nyore kuronga uye kugadzirisa pamberi peiyo chaiyo welding. Tanga nekukurumidza, kugadzirisa kwakaringana kuti uve nechokwadi chekuenderana, kwakachena uye kwakavimbika weldments.
Chikwata cheAxenics 'chevacheki muMiddleton, Massachusetts, igadziriso yekondirakiti inotungamira vazhinji vevatengi vayo mu orbital welding maitiro kana zvinhu zvakanaka zviripo zvebasa racho.
“Pazvaibvira, taida kubvisa chinhu chiri mumunhu muwelding, sezvo maorbital welders achiwanzobudisa maweldhi emhando yepamusoro,” anodaro Tom Hammer, nyanzvi yokunama paAxenics.
Kunyange zvazvo welding yekutanga yakaitwa makore 2000 apfuura, welding yemazuva ano inzira yakanyanyisa kukosha iyo inokosha kune humwe hunyanzvi hwemazuva ano uye maitiro.Semuyenzaniso, orbital welding inogona kushandiswa kugadzira iyo yepamusoro-yakachena pombi masisitimu anoshandiswa kugadzira semiconductor wafers anopinda mumagetsi ese nhasi.
Mumwe wevatengi veAxenics chikamu cheiyi cheni yekugovera. Yakatsvaga mugadziri wekondirakiti kuti abatsire kuwedzera huwandu hwayo hwekugadzira, kunyanya kugadzira nekuisa dzakachena simbi isina tsvina nzira dzinobvumira magasi kupfuura nepakati pekugadzira wafer.
Nepo orbital welding mayunitsi uye matafura anotenderera ane torch clamps aripo kune mazhinji tubular mabasa kuAxenics, izvi hazvidzivise pano neapo welding.
Hammer nechikwata chewelding vakaongorora zvinodiwa nemutengi uye vakabvunza mibvunzo, vachifunga nezve mutengo uye nguva zvinhu:
Iwo anotenderera akavharirwa orbital welders anoshandiswa neHammer ndeye Swagelok M200 uye Arc Machines Model 207A. Vanogona kubata 1/16 kusvika 4 inch tubing.
"Microheads inotitendera kuti tipinde munzvimbo dzakasimba kwazvo," akadaro. "Chimwe chinodzikisira che orbital welding ndechekuti isu tine musoro unoenderana nejoint chaiyo. Asi nhasi, iwe unogona zvakare kuputira cheni kutenderedza pombi yauri welding. Iyo welder inogona kuenda pamusoro pecheni, uye hapana muganho kuhukuru hwewelds iwe unogona kuita. . zvinoshamisa zvinogona kuitwa nemichina iyi nhasi.”
Tichifunga nezvekuchena zvinodiwa, huwandu hwemawelds anodiwa, uye kutetepa kwemadziro ukobvu, orbital welding isarudzo yakangwara yerudzi urwu rweprojekiti.Kuti airflow process control piping work, Hammer inowanzo stains pa316L simbi isina tsvina.
"Ndipo pazvinova zvinyengeri chaizvo. Tiri kutaura nezve welding papepa simbi yakatetepa. Nekusungirirwa kwemaoko, kugadzirisa kuduku kunogona kuputsa weld. Ndosaka tichida kushandisa orbital weld head, kwatinogona Dial muchikamu chimwe nechimwe chechubhu uye kuita kuti ive yakakwana tisati taisa chikamu mairi. Isu tinodzora pasi simba kune imwe chiyero kuitira kuti tizive kuti chikamu chiri muruoko, chatinozoisa paruoko, tichazove nekuchinja. uye kana tikanyanya kuchovha, inogona kupinda nemukati mechinhu chacho. ”
Basa racho rine mazana emawelds anofanira kunge akafanana.The orbital welder inoshandiswa basa iri inoita weld mumaminitsi matatu; apo Hammer iri kuita zvekumhanya kwazvo, anogona nemaoko weld the same stainless simbi chubhu muinenge miniti.
"Zvisinei, muchina uyu hausi kudzikira. Unoumhanyisa nekukurumidza chinhu chekutanga mangwanani, uye pakupera kwezuva, uchiri kumhanya zvakanyanya," akadaro Hammer. "Ndinoimhanyisa nekukurumidza chinhu chekutanga mangwanani, asi mukupedzisira, handizvo."
Kudzivirira kusvibiswa kubva pakupinda simbi yesimbi yesimbi kwakakosha, ndicho chikonzero chepamusoro-kuchena soldering muindasitiri ye semiconductor inowanzoitwa muimba yakachena, nzvimbo inodzorwa inodzivirira kusvibiswa kupinda munzvimbo yakatengeswa.
Hammer inoshandisa zvakafanana kare-yakarodzwa tungsten mumaoko ake mazhenje kuti anoshandisa muOrbiter.Nepo argon yakachena inopa kunze uye mukati kucheneswa mune manual uye orbital welding, welding nemichina orbital inobatsirawo kubva pakuitwa munzvimbo yakavharwa.Apo tungsten inobuda, goko rinozadza negasi uye rinodzivirira weld kubva kune gas side torch chete, Paunenge uchishandisa gas rimwe divi re torch. iri kugadzirwa izvozvi.
Orbital welds kazhinji yakachena nekuti gasi rinovhara chubhu kwenguva refu.Kana welding yatanga, argon inopa dziviriro kusvikira welder aine chokwadi chekuti weld inotonhora zvakakwana.
Axenics inoshanda nehuwandu hwemamwe magetsi emagetsi emagetsi anogadzira hydrogen mafuta masero anosimbisa motokari dzakasiyana-siyana.Semuenzaniso, mamwe maforklifts akavakirwa kuti ashandiswe mukati anovimba nehydrogen mafuta emasero kudzivirira makemikari emakemikari kubva pakuparadza masheya anodyiwa.Iyo chete ne-chigadzirwa chehydrogen fuel cell imvura.
Mumwe wevatengi aiva nezvakawanda zvezvinodiwa semiconductor mugadziri, akadai weld kuchena uye consistency.Inoda kushandisa 321 simbi isina tsvina kune yakaonda rusvingo welding.Zvisinei, basa racho rakanga riri prototyping manifold ane mabhanga akawanda evharuvhu, rimwe nerimwe richibuda mune imwe nzira, richisiya nzvimbo duku yekugadzira.
An orbital welder yakakodzera basa inodhura inenge madhora 2 000, uye inogona kushandiswa kuita nhamba shoma yezvikamu, ine mari inofungidzirwa ye $ 250. Hazvina musoro mune zvemari.Zvisinei, Hammer ine mhinduro inobatanidza manyore uye orbital welding maitiro.
"Panyaya iyi, ndingashandisa tafura inotenderera," anodaro Hammer. "Chaizvoizvo chiito chakafanana seye orbital welder, asi iwe uri kutenderera chubhu, kwete tungsten electrode yakakomberedza chubhu. Ndinoshandisa torch yangu yeruoko, asi ndinokwanisa kubata torch yangu panzvimbo ine vise Yakaiswa kuitira kuti irege maoko kuitira kuti weld irege kubvisa kukanganisa kwemaoko evanhu. isina kukwana senge orbital welding nekuti haisi munzvimbo yakavharirwa, asi rudzi urwu rweThe welding inogona kuitwa munzvimbo yakachena yekamuri kubvisa zvinosvibisa.
Nepo orbital welding tekinoroji ichipa kuchena uye kudzokororwa, Hammer nevamwe vaanoshanda navo vanoziva kuti weld kutendeseka kwakakosha pakudzivirira nguva yekudzikira nekuda kwekutadza kweweld.Kambani inoshandisa isiri-inoparadza kuyedza (NDT), uye dzimwe nguva inoparadza kuyedza, kune ese orbital welds.
"Yese weld yatinogadzira inosimbiswa nekuona," anodaro Hammer. "Mushure mezvo, ma weld anoongororwa nehelium spectrometer. Zvichienderana nekutsanangurwa kana zvinodiwa nevatengi, mamwe mawelds anoongororwa radiographically.
Kuedza kunoparadza kunogona kusanganisira kuedza kwesimba remagetsi kuti uone simba rekupedzisira rekusimba kwe weld.Kuyera kushushikana kwakanyanya kwe weld pane zvinhu zvakadai se 316L simbi isina tsvina inogona kumira isati yakundikana, muedzo unotambanudza uye unotambanudza simbi kusvika pakuputsika kwayo.
Welds neamwe magetsi vatengi dzimwe nguva anoiswa kune ultrasonic nondestructive kuyedzwa pachikamu cheweldments yetatu-channel heat exchanger hydrogen mafuta maseru anoshandiswa mune mamwe magetsi emagetsi uye mota.
“Uyu muyedzo wakaoma nekuti zvinhu zvizhinji zvatinotumira zvine magasi ane njodzi ari kupfuura nemazviri. Zvakakosha kwatiri nevatengi vedu kuti simbi isina chainopomerwa haina chainopomerwa, iine zero inobuda,” anodaro Hammer.
