Njira yowotcherera ya Argon arc
Argon arc ndi ntchito yomwe manja akumanzere ndi akumanja amayenda nthawi imodzi, zomwe zimakhala zofanana ndi kujambula mabwalo ndi dzanja lamanzere ndikujambula mabwalo ndi dzanja lamanja m'moyo wathu watsiku ndi tsiku. Choncho, tikulimbikitsidwa kuti omwe angoyamba kumene kuphunzira kuwotcherera argon arc ndi maphunziro ofanana, zomwe zingakhale zothandiza kuphunzira kuwotcherera kwa argon arc.
(1) Kudyetsa mawaya: kugawidwa m'mawaya amkati ndi kudzaza mawaya akunja.
Waya wodzaza kunja ukhoza kugwiritsidwa ntchito poyambira ndi kudzaza. Amagwiritsa ntchito mphamvu yaikulu. Mutu wa waya wowotcherera uli kutsogolo kwa poyambira. Dzanja lamanzere limatsina waya wowotcherera ndikutumiza mosalekeza mu dziwe losungunuka kuti liwotcherera. Kusiyana kwa groove kumafuna mpata wawung'ono kapena wopanda.
Ubwino wake ndikuchita bwino kwambiri komanso luso losavuta kugwiritsa ntchito chifukwa cha kusiyana kwakukulu komwe kulipo komanso kochepa. Choyipa chake ndikuti ngati chikugwiritsidwa ntchito pansi, chifukwa wogwiritsa ntchito sangathe kuwona kusungunuka kwa m'mphepete mwake ndikulimbitsa mbali yakumbuyo, ndikosavuta kutulutsa mosasunthika komanso osapeza mawonekedwe oyenera.
Waya wamkati umatha kugwiritsidwa ntchito powotcherera kumbuyo. Gwiritsani ntchito chala chachikulu, chala chamlozera kapena chala chapakati cha dzanja lanu lamanzere kuti mugwirizanitse ntchito yodyetsera mawaya. Chala chaching'ono ndi chala champhete zimalimbitsa waya wowotcherera kuti ziwongolere komwe akupita. Waya wowotcherera ali pafupi ndi m'mphepete mwa nsonga ndipo amasungunuka pamodzi ndi m'mphepete mwa kuwotcherera, kusiyana kwa poyambira kumafunika kukhala kwakukulu kuposa kukula kwa waya wowotcherera. Ngati ndi mbale, waya wowotcherera amatha kupindika kukhala arc.
Ubwino wake ndikuti chifukwa waya wowotcherera uli mbali ina ya poyambira, m'mphepete mwake ndi mawonekedwe osungunuka a waya wowotcherera amatha kuwoneka momveka bwino, ndipo kulimbitsanso kumbuyo kumawonekera kuchokera ku masomphenya ozungulira a maso, weld fusion ndiyabwino, ndipo kulimbikitsanso kumbuyo ndi kusaphatikizika kumatha kuyendetsedwa bwino. Choyipa chake ndi chakuti ntchitoyo ndi yovuta, ndipo wowotcherera amafunikira kukhala ndi luso laukadaulo. Chifukwa kusiyana ndi kwakukulu, voliyumu yowotchera idzawonjezeka moyenerera. Kusiyana kwake ndi kwakukulu, kotero kuti panopa ndi yochepa, ndipo ntchito yogwira ntchito imachedwa pang'onopang'ono kusiyana ndi waya wodzaza kunja.
(2) Zogwirira ntchito zowotcherera zimagawidwa kukhala zogwirira ntchito ndi ma mops.
Chogwirira chogwedeza ndikukankhira chowotcherera pang'ono pa msoko wowotcherera, ndikugwedeza mkono kwambiri kuti muwotchere. ubwino wake ndi chifukwa kuwotcherera nozzle ndi mbamuikha pa kuwotcherera msoko, ndi kuwotcherera chogwiririra ndi khola kwambiri pa ntchito, kotero kuwotcherera msoko ndi bwino kutetezedwa, khalidwe ndi zabwino, maonekedwe ndi wokongola kwambiri, ndi mlingo kuyenerera mankhwala ndi mkulu. . Amapeza mtundu wowoneka bwino kwambiri. Choyipa chake ndikuti ndizovuta kuphunzira, chifukwa mkono umagwedezeka kwambiri, kotero ndizosatheka kuwotcherera pa zopinga.
Mphunoyo imatanthawuza kuti nsonga yowotcherera imatsamira mopepuka kapena osatsamira pa msoko wowotcherera, chala chaching'ono kapena mphete ya dzanja lamanja imatsamiranso kapena osatsamira pa chogwirira ntchito, mkono umagwedezeka pang'ono, ndikukokera chogwirira. za kuwotcherera. Ubwino wake ndikuti ndi wosavuta kuphunzira komanso wosinthika bwino. Kuipa kwake ndikuti mawonekedwe ndi mawonekedwe ake sizigwedezeka bwino, makamaka pakuwotcherera pamwamba popanda shaker kuti athandizire kuwotcherera. Ndizovuta kupeza mtundu ndi mawonekedwe abwino powotcherera zitsulo zosapanga dzimbiri.
(3) Kuwotcha kwa arc: Kuwotcha kwa arc nthawi zambiri kumagwiritsidwa ntchito (oscillator wapamwamba kwambiri kapena jenereta yamagetsi apamwamba), ndipo ma elekitirodi a tungsten ndi weldment samalumikizana kuti ayambitse arc. Ngati palibe kuyatsa kwa arc, kuyatsa kwa arc kumagwiritsidwa ntchito (komwe kumagwiritsidwa ntchito kwambiri m'malo omanga) kukhazikitsa, makamaka kuyika kwapamwamba), mkuwa kapena graphite imatha kuyikidwa pamphuno ya weldment kuti ikanthe arc, koma njira iyi ndiyowonjezera. zovuta komanso zosagwiritsidwa ntchito. Nthawi zambiri, kugunda kopepuka kokhala ndi waya wowotcherera kumapangitsa kuti chowotcherera ndi ma elekitirodi a tungsten afupike komanso kulumikizidwa mwachangu. Ndipo kuyatsa arc.
(4) Kuwotcherera: Pambuyo poyatsira arc, m'pofunika kutenthetsa kwa masekondi 3-5 kumayambiriro kwa kuwotcherera, ndikuyamba kudyetsa waya pambuyo pa dziwe losungunuka. Powotcherera, mbali ya waya wowotchererayo iyenera kukhala yoyenera, ndipo waya wowotcherera uyenera kudyetsedwa mofanana. Muuni wowotcherera uyenera kupita patsogolo bwino, kutembenukira kumanzere ndi kumanja pang'onopang'ono mbali zonse ziwiri, komanso mwachangu pakati. Samalani kwambiri kusintha kwa dziwe losungunuka. Dziwe losungunuka likamakula, msoko wowotcherera umakhala wokulirapo, kapena msoko wowotcherera umakhala wopindika, liwiro la kuwotcherera liyenera kuonjezedwa kapena kuwotcherera kwapano kuchepenso. Pamene kuphatikizika kwa dziwe losungunuka sikuli bwino ndipo waya sangathe kudyetsedwa, m'pofunika kuchepetsa liwiro la kuwotcherera kapena kuonjezera kuwotcherera panopa. Ngati ndi kuwotcherera pansi, maso ayenera kuyang'ana m'mbali zosamveka mbali zonse za poyambira, ndi ngodya za maso. Kuwala kwapang'onopang'ono kuli mbali ina ya kung'ambika, ndipo samalani ndi kusintha kwa kutalika kwina.
5) Kuzimitsa kwa Arc: Ngati arc yazimitsidwa mwachindunji, n'zosavuta kupanga shrinkage cavity. Ngati nyali yowotcherera ili ndi choyambira, arc iyenera kutsekedwa pang'onopang'ono kapena kusinthidwa kuti ikhale yoyenera. Arc imatsogoleredwa ku mbali imodzi ya poyambira, ndipo palibe dzenje la shrinkage lomwe limapangidwa. Ngati dzenje la shrinkage lichitika, liyenera kupukutidwa musanayambe kuwotcherera.
Ngati arc ili pamgwirizano, mgwirizanowo uyenera kugwedezeka kukhala bevel poyamba, ndiyeno welded patsogolo 10-20mm pamene mgwirizanowo wasungunuka, ndiyeno arc imatsekedwa pang'onopang'ono, ndipo palibe phokoso la shrinkage lomwe lingachitike. Popanga, nthawi zambiri zimawoneka kuti zolumikizira sizimapukutidwa kukhala ma bevel, ndipo nthawi yowotcherera yolumikizira imakulitsidwa mwachindunji pazolumikizana. Ichi ndi chizoloŵezi choipa kwambiri. Mwanjira imeneyi, zolumikizirazo zimakhala zosavuta kukhala concave, zolumikizira zomwe sizinaphatikizidwe ndipo mbali yakumbuyo imakhala yosagwirizana, zomwe zingakhudze mawonekedwe a mawonekedwe. Ngati ndi aloyi wapamwamba Zinthuzi zimakondanso ming'alu.
