Zosankha za Medium Frequency Spot Welder Parameters?

Ma welds apakati pafupipafupi amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana kuti athe kupanga ma welds amphamvu komanso olondola pakanthawi kochepa. Owotcherera awa amapereka zosankha zingapo zomwe zingasinthidwe kuti mukwaniritse zotsatira zabwino kwambiri zowotcherera. M'nkhaniyi, tiwona njira zazikuluzikulu zomwe zilipo kwa ma welder apakati pafupipafupi.

1. Welding Panopa:Chimodzi mwazofunikira kwambiri ndi kuwotcherera pakali pano, komwe kumatsimikizira kuchuluka kwa kutentha komwe kumapangidwa panthawi yowotcherera. Kuwotcherera kwamphamvu kumapangitsa kuti ma welds amphamvu kwambiri, koma kuchulukirachulukira kumatha kupangitsa kuti zinthu zisinthe kapenanso kuyaka. Kupeza njira yoyenera n'kofunika kwambiri.
2. Nthawi Yowotcherera:Nthawi yowotcherera ndi nthawi yomwe kuwotcherera kwapano kumagwiritsidwa ntchito kuzinthu zogwirira ntchito. Zimagwira ntchito yofunikira pakuwongolera kulowetsa kwa kutentha ndi mtundu wonse wa weld. Kuwotchera kwakanthawi kochepa kumatha kupangitsa kuti ma welds afooke, pomwe nthawi yayitali imatha kuyambitsa kutentha kwambiri komanso kuwonongeka kwa zida.
3. Mphamvu ya Electrode:Mphamvu ya elekitirodi ndi kukakamiza komwe kumagwiritsidwa ntchito kuzinthu zogwirira ntchito panthawi yowotcherera. Mphamvu yokwanira ya ma elekitirodi imatsimikizira kulumikizana kwabwino pakati pa zogwirira ntchito ndikuthandizira kukwaniritsa ma welds osasinthika. Komabe, mphamvu yochulukirapo imatha kusokoneza zida kapena kupangitsa kuti ma electrode avale.
4. Electrode Diameter ndi Mawonekedwe:Kukula ndi mawonekedwe a ma elekitirodi owotcherera amatha kukhudza kugawa kwa kutentha ndi kukakamiza panthawi yowotcherera. Kusankha ma elekitirodi oyenerera ndi mawonekedwe a ntchito yeniyeni kungathandize kuti ma welds a yunifolomu achepetse zotsatira zosafunikira.
5. Electrode Material:Ma elekitirodi nthawi zambiri amapangidwa kuchokera ku ma alloys amkuwa chifukwa cha kuwongolera kwawo komanso kukana kutentha. Zida zosiyanasiyana zama elekitirodi zitha kufunikira kutengera zida zomwe zimawotcherera komanso mtundu womwe mukufuna.
6. Welding Mode:Ma welder apakati pafupipafupi amapereka mitundu ingapo yowotcherera, monga single-pulse, double-pulse, kapena multiple-pulse modes. Mitundu iyi imayang'anira kutsata komanso nthawi yamagetsi akuwotcherera, zomwe zimakhudza kulowa kwa weld ndi kupanga nugget.
7. Nthawi Yoziziritsa:Pambuyo pa kuwotcherera pakali pano kuzimitsidwa, nthawi yozizira imagwiritsidwa ntchito nthawi zambiri ma elekitirodi asanayambe kukwezedwa. Izi zimathandiza kuti malo owotchererawo azizizira pansi ndi kulimba, zomwe zimathandiza kuti weld akhale wamphamvu.
8. Polarity:Ma welder ena apakati pafupipafupi amalola kuti polarity ya welding pano isinthe. Polarity imatha kukhudza momwe kutentha kumayendera komanso mtundu wonse wa weld.
9. Magawo a Pre-Welding ndi Post-Welding:Izi ndi nthawi zowonjezera zapansi zomwe zimagwiritsidwa ntchito isanayambe kapena itatha kuwotcherera kwambiri. Amathandizira kuchepetsa kusokonekera kwazinthu komanso kupsinjika kwapang'onopang'ono kuzungulira zone weld.

Pomaliza, magwiridwe antchito a sing'anga pafupipafupi malo kuwotcherera kumadalira kwambiri kuwongolera kolondola kwa magawo osiyanasiyana owotcherera. Opanga ndi ogwiritsira ntchito akuyenera kuganizira zosankhazi mosamala kuti akwaniritse zomwe akufuna, mphamvu, komanso kusasinthika kwazinthu zinazake. Kusankhidwa koyenera kwa magawo ndi kusintha kungayambitse njira zopangira zopangira komanso zinthu zapamwamba zowotcherera.
