Mu mafakitale owotcherera, pali ambirimitundu ya kuwotcherera. Kuwotcherera ndi kuwotcherera ma arc ndi zina mwa njira zodziwika bwino. Nthawi zambiri amagwiritsidwa ntchito m'magawo osiyanasiyana ndipo amagwira ntchito zofunika m'mafakitale osiyanasiyana. Monga woyamba, zingakhale zovuta kumvetsa kusiyana kwake. Ngati mukufuna kuphunzira za kusiyana kwa kuwotcherera kwa arc ndi kuwotcherera mawanga, nkhani yotsatirayi ifotokoza mwatsatanetsatane.

Kodi Arc Welding ndi Chiyani?

Kuwotcherera kwa arcndi njira yomwe imagwiritsa ntchito kutentha kopangidwa ndi arc yamagetsi kuti isungunuke ndikulumikiza zitsulo pamodzi. Gwero lamagetsi la kuwotcherera kwa arc limatha kupereka mwachindunji panopa (DC) kapena alternating current (AC). Kutengera zofunikira zowotcherera, kuwotcherera kwa arc kumatha kugwiritsa ntchito ma elekitirodi ogwiritsidwa ntchito kapena osagwiritsidwa ntchito. Wopangidwa kumapeto kwa zaka za m'ma 1800, kuwotcherera kwa arc kudatenga gawo lalikulu pakumanga zombo ndipo kumagwiritsidwanso ntchito kwambiri m'mafakitale amagalimoto ndi olemera.

Kodi Spot Welding N'chiyani?

Spot kuwotcherera ndi mawonekedwe akukana kuwotchererayomwe imagwiritsa ntchito magetsi kuti ipangitse kutentha ndi kukakamiza, zomwe zimapangitsa kuti malo olumikizirana pakati pa zogwirira ntchito apange chitsulo cha weld nugget kapena pulasitiki ndikulumikizana. Ndi njira yowotcherera yachikhalidwe yomwe imagwiritsa ntchito maelekitirodi amkuwa poyendetsa magetsi. Mphamvu yamagetsi imadutsa pazitsulo zogwirira ntchito, kuzisungunula pazigawo zogwirizanitsa, ndipo pamene panopa imasiya, kupanikizika kumapitirizabe kugwirizanitsa mfundo zogwirizanitsa pamodzi, kupanga mgwirizano.

Kusiyana Pakati Pa Welding Arc Ndi Spot Welding

Mfundo Yowotcherera

Kuwotcherera kwa Arc ndi kuwotcherera mawanga kumagwira ntchito mosiyanasiyana. Kuwotcherera kwa Arc kumagwiritsa ntchito electrode ndi chogwirira ntchito kuti apange arc yamagetsi, kutulutsa kutentha. Kutentha kwakukulu kumasungunula electrode kukhala madzi omwe amadzaza chitsulo cholumikizira ndi kuzizira kuti apange weld, kulumikiza zigawo ziwiri zachitsulo. Iyi ndi njira yowotcherera yamadzimadzi.

Kuwotcherera malo, kumbali ina, kumaphatikizapo kuunjika zida ziwiri zogwirira ntchito ndikuyika mphamvu ndi maelekitirodi awiri. Magetsi amatenthetsa malo olumikizirana pakati pa maelekitirodi ndi zida zogwirira ntchito, ndikupangitsa kuti zisungunuke. Pakuzizira, zigawozo zimagwirizanitsidwa palimodzi, zomwe zimapangitsa kuti zikhale zogwirizana ndi dziko.

Zofunikira pa Filler Material

Powotcherera, kuwotcherera kwa arc kumatha kugwiritsa ntchito zitsulo zodzaza kapena ayi. Mukawotchera zida ziwiri zogwirira ntchito limodzi, zinthu zodzaza sizingasowe kufunikira. Kuwotcherera malo sikufuna zinthu zodzaza; imatenthetsa mwachindunji zida zogwirira ntchito ku pulasitiki kuti zigwirizane nazo.

Kuchuluka kwa ntchito

Spot kuwotcherera ndi kuwotcherera arc kuli ndi ntchito zosiyanasiyana. Kuwotcherera kwa Arc ndikoyenera kuwotcherera mawonekedwe ovuta ndi zida zazikulu zachitsulo, zomwe zimapangitsa kuti zikhale zoyenera kukonza ndi kukonza magawo akulu ndi ntchito zamakampani olemera. Spot kuwotcherera nthawi zambiri kumagwiritsidwa ntchito pazigawo zing'onozing'ono pafupifupi 3 millimeters wandiweyani ndipo ndikwabwino kuwotcherera kwamphamvu kwambiri. Amagwiritsidwa ntchito kwambiri m'mafakitale amagalimoto ndi zida zapanyumba.

Nthawi Yowotcherera

Arc kuwotcherera chitsulo kumatenga nthawi yayitali ndipo sizochitika kamodzi. Spot kuwotcherera ndikofulumira kwambiri ndipo kumatha kumaliza malonda mumphindi imodzi kapena masekondi angapo.

Mtengo Wowotcherera

Kuwotcherera kwa Arc kuli ndi mtengo wochepa wowotcherera, koma chifukwa cha zovuta zake zaukadaulo, ndalama zogwirira ntchito zaluso zowotcherera ndi zokwera. Spot kuwotcherera kuli ndi mtengo wokwera, ndi imodzimakina kuwotcherera malookwera mtengo ngati makina angapo owotcherera arc. Komabe, mtengo wa ntchito kwa ogwira ntchito ndi wotsika, zomwe zingapulumutse ndalama pakapita nthawi.

Chofunikira cha Kupanikizika Kwakunja

Pazofunikira zakunja, kuwotcherera arc nthawi zambiri sikufuna kukakamiza kwakunja. Arc yopangidwa ndi gwero lamagetsi imasungunula chogwirira ntchito ndi zinthu zodzaza. Kuwotcherera malo, komabe, kumafuna kuthamanga kwa mpweya kuti akanikizire zida ziwirizo, ndiyeno kutentha kumapangidwa kudzera pakalipano.

Chitetezo cha ntchito

Kuwotcherera kwa Arc ndizovuta mwaukadaulo ndipo kumafunikira ma welder aluso. Ngati mukufuna kugwiritsa ntchito kuwotcherera arc, muyenera kuphunzitsidwa akatswiri. Spot kuwotcherera ndi kosavuta komanso kotetezeka, kumafuna luso lochepa. Othandizira amangofunika maphunziro oyambira kuti ayambe.

Pomaliza:

Pamwambapa pali kusiyana kwakukulu pakati pa kuwotcherera kwa arc ndi kuwotcherera mawanga. Posankha njira yowotcherera, muyenera kuganizira mfundo izi. Kaya musankhe kuwotcherera pamalo kapena kuwotcherera kwa arc makamaka zimatengera chinthu chomwe muyenera kuwotcherera, zida zake, ndi mawonekedwe ake. Mwachitsanzo, ngati mukufuna kuwotcherera chitoliro chachikulu chachitsulo chosapanga dzimbiri, ndi bwino kusankha kuwotcherera kwa arc chifukwa kuwotcherera kwa malo ndikoyenera pazigawo zing'onozing'ono. Chifukwa chake musanasankhe njira yowotcherera, onetsetsani kuti mwasanthula chilichonse kuchokera pamalingaliro angapo.
