Argon arc welding operation nzira
Argon arc oparesheni umo mawoko ekuruboshwe nekurudyi anofamba panguva imwe chete, zvakangofanana nekudhirowa madenderedzwa neruoko rweruboshwe uye kudhirowa masikweya neruoko rwerudyi muhupenyu hwedu hwezuva nezuva.Nokudaro, zvinokurudzirwa kuti avo vachangotanga kudzidza argon arc welding vane kudzidziswa kwakafanana, izvo zvichabatsira kudzidza argon arc welding.
(1) Kudyisa waya: yakakamurwa kuita yemukati kuzadza waya uye yekunze kuzadza waya.
Iyo yekunze yekuzadza waya inogona kushandiswa priming uye kuzadza.Inoshandisa simba guru.Musoro wewaya yewelding uri kumberi kwegorofu.Ruoko rworuboshwe runonanzva waya yewelding uye ichiramba ichiitumira mudziva rakanyungudutswa kuti rive welding.Iyo groove gap inoda diki kana kuti isina gap.
Mabhenefiti ayo akakwira kugadzirwa kwehunyanzvi uye nyore hunyanzvi hwekushandisa nekuda kweiyo hombe yazvino uye diki gap.Kukanganisa kwayo ndeyekuti kana ikashandiswa kudzika pasi, nekuti mushandisi haakwanise kuona kunyunguduka kwemupendero wakashata uye kusimbiswa kwedivi reshure, zviri nyore kuburitsa isina kusanganiswa uye kusawana yakanakira reverse kuumba.
Iyo yemukati yekuzadza waya inogona chete kushandiswa kutsigira welding.Shandisa chigunwe, chigunwe che index kana chigunwe chepakati cheruoko rwako rweruboshwe kuronga chiito chekudyisa waya.Chigunwe chidiki nemunwe wemhete zvinosungirira waya yewelding kuti idzore kwainoenda.Iyo welding wire iri padyo neyakavhurika mupendero mukati me groove uye inonyungudika pamwe chete neyakavhurika edge For welding, iyo groove gap inodiwa kuti ive yakakura kudarika dhayamita yewaya welding.Kana iri ndiro, waya yewelding inogona kukoneswa kuita arc.
Kubatsira kwaro ndekwekuti nekuti waya yekushongedza iri kune rumwe rutivi rwegorovha, iyo yakagomara mupendero uye mamiriro ekunyunguduka kwewaya welding anogona kuoneka zvakajeka, uye iyo reverse yekusimbisa inogona kuoneka kubva pakuona kwemeso kwemeso, saka iyo yekusimbisa yekudzosera kumashure inogona kuoneka kubva pakuona kwemeso. weld fusion yakanaka, uye iyo reverse yekusimbisa uye isiri-fusion inogona kuwanikwa kutonga kwakanaka.Izvo zvakashata ndezvekuti kuvhiya kwakaoma, uye welder anodiwa kuti ave nehunyanzvi hwekuita hunyanzvi.Nekuti gap rakakura, iyo welding vhoriyamu ichawedzera zvinoenderana.Iyo gap yakakura, saka ikozvino yakaderera, uye kushanda kwekushanda kunononoka kupfuura iyo yekunze filler wire.
(2) Welding zvibato zvakakamurwa kuita crank mibato uye mops.
Mubato unozunguza ndeyekudzvanya muromo we welding zvishoma pane welding seam, uye zunza ruoko zvakanyanya kuti weld.Zvakanakira nekuti iyo welding nozzle inotsikirirwa pamusono we weld, uye welding mubato wakanyatsogadzikana panguva yekushanda, saka weld seam yakachengetedzwa zvakanaka, mhando yakanaka, chitarisiko chakanaka kwazvo, uye chiyero chekukodzera chigadzirwa chakakwira. .Inowana ruvara rwakanaka kwazvo.Izvo zvisingabatsiri ndezvokuti zvakaoma kudzidza, nokuti ruoko runozunungusa zvakanyanya, saka hazvibviri kusungira pane zvipingamupinyi.
Mop (mop) zvinoreva kuti chigunwe chewelding chinozembera pachiri kana kusazembera pakasonwa, kagunwe kadiki kana rin'i yeruoko rwerudyi zvakare inozembera kana kusazembera paworkpiece, ruoko rwunoita diki, uye rwunokweva mubato wewelding. yewelding.Chakanakira chayo ndechekuti iri nyore kudzidza uye ine yakanaka kuchinjika.Kukanganisa kwayo ndeyekuti chimiro uye kunaka hazvizununguswi zvakanaka, kunyanya kune welding wepamusoro pasina shaker kufambisa welding.Zvakaoma kuwana ruvara rwakanaka uye chimiro kana uchiisa simbi isina tsvina.
(3) Arc ignition: Arc ignition inowanzoshandiswa (yakakwirira-frequency oscillator kana high-frequency pulse generator), uye tungsten electrode uye weldment hazvibatanidzi kupisa arc.Kana pasina arc ignition, kubata arc ignition inoshandiswa (inonyanya kushandiswa munzvimbo dzekuvaka) kuiswa, kunyanya kuiswa kwepamusoro-soro), mhangura kana graphite inogona kuiswa pane groove ye weldment kuti irove arc, asi nzira iyi yakawanda. zvinonetsa uye zvishoma kushandiswa.Kazhinji, siroko yakapfava ine waya yewelding inoita kuti weldment uye tungsten electrode ipfupike-inotenderedzwa uye nekukurumidza kubviswa.Uye kubatidza arc.
(4) Welding: Mushure mekunge arc yadzimwa, zvakakosha kuti utange kupisa kwemasekondi 3-5 pakutanga kweweldment, uye kutanga kudyisa waya mushure mokunge dziva rakanyungudutswa raumbwa.Kana welding, kona yewelding wire torch inofanira kunge yakakodzera, uye waya welding inofanira kudyiswa zvakaenzana.Tochi yewelding inofanira kufambira mberi zvakanaka, ichitenderedza kuruboshwe nekurudyi zvishoma nezvishoma kumativi ese, uye ichimhanya zvishoma pakati.Nyatsocherechedza kuchinja kwedziva rakanyungudutswa.Kana dziva rakanyungudutswa rakura, musono we weld unova wakafara, kana welding seam ikava concave, kumhanya kwewelding kunofanira kuwedzerwa kana kuti welding current inofanira kudzikiswa zvakare.Kana iyo fusion yedziva yakanyungudutswa isina kunaka uye waya haigone kudyiswa, zvinodikanwa kudzikisa kumhanya kwewelding kana kuwedzera welding ikozvino.Kana iri pasi welding, maziso anofanira kutarisa pamicheto isina kujeka kumativi ose egorofu, uye makona emeso.Chiedza cheperipheral chiri kune rumwe rutivi rwekutsemuka, uye teerera kune shanduko yemamwe marefu.
5) Kudzima kweArc: Kana iyo arc yakadzimwa zvakananga, zviri nyore kugadzira shrinkage cavity.Kana tochi yewelding ine arc starter, iyo arc inofanira kuvharwa nguva nenguva kana kugadziriswa kune yakakodzera arc crater current.Iyo arc inotungamirwa kune rumwe rutivi rwegorofu, uye hapana shrinkage gomba rinoumbwa.Kana gomba rekupwanya rikaitika, rinofanirwa kukwenenzverwa risati ranyura.
Kana iyo arc iri pajoinhi, mubatanidzwa unofanirwa kugadzika kuita bevel kutanga, uye wozoiswa mberi 10-20mm mushure mekunge mubatanidzwa wanyungudika, uye ipapo arc inovharwa zvishoma nezvishoma, uye hapana shrinkage cavity inogona kuitika.Mukugadzirwa, zvinowanzoonekwa kuti majoini haana kuputirwa kuva bevels, uye nguva yekuputika yezvibatanidza inorebeswa zvakananga kune majoini.Iyi itsika yakaipa zvikuru.Nenzira iyi, majoini anowanzoita concave, majoini asina kusanganiswa uye reverse side iri kunze kwekubatana, izvo zvinokanganisa kutaridzika kwechimiro.Kana iri high alloy Nyaya yacho inowanzoita kuputika.
