Kufotokozera Mwakuya kwa Welding Current Curve mu Medium Frequency Inverter Spot Welding Machines

Ma curve akuwotcherera apano amatenga gawo lofunikira pakuwotcherera kwamakina apakati pafupipafupi inverter spot kuwotcherera. Zimayimira kusiyanasiyana kwa kuwotcherera komweko pakapita nthawi ndipo zimakhudza kwambiri mtundu ndi mawonekedwe a weld. Nkhaniyi ikufotokoza mwatsatanetsatane za kuwotcherera panopa pamapindikira mu sing'anga pafupipafupi inverter malo kuwotcherera makina.

1. Current Ramp-Up: Njira yowotcherera yomwe ilipo imayamba ndi gawo lokwera, pomwe kuwotcherera kumawonjezeka pang'onopang'ono kuchokera paziro kupita pamtengo wodziwikiratu. Gawoli limalola kuti pakhale mgwirizano wokhazikika wamagetsi pakati pa maelekitirodi ndi ma workpieces. Kutalika kwa nthawi yokwera ndi kuchuluka kwake kumatha kusinthidwa kutengera zinthu, makulidwe, ndi magawo omwe mukufuna kuwotcherera. Kuwongolera kowongolera komanso kosalala kwapano kumathandizira kuchepetsa kukwapula ndikupangitsa kuti ma weld nugget apangidwe mosasintha.
2. Welding Current Pulse: Potsatira njira yomwe ilipo, kuwotcherera kwapano kumalowa mu gawo la pulse. Panthawi imeneyi, magetsi okhazikika amagwiritsidwa ntchito kwa nthawi yeniyeni, yotchedwa nthawi yowotcherera. Kuwotcherera kwapano kumatulutsa kutentha pamalo olumikizirana, kuchititsa kusungunuka komweko ndi kulimba kotsatira kuti apange nugget ya weld. Kutalika kwa kuwotcherera kwapano kumatsimikiziridwa ndi zinthu monga mtundu wa zinthu, makulidwe, ndi mtundu womwe mukufuna. Kuwongolera koyenera kwa nthawi ya kugunda kumatsimikizira kutentha kokwanira ndikupewa kutenthedwa kapena kutenthedwa kwa ntchito.
3. Kuwola Panopa: Pambuyo pakuwotcherera kwapano, mphamvuyi imawola pang'onopang'ono kapena kutsika mpaka ziro. Gawoli ndi lofunikira pakukhazikika kokhazikika komanso kuziziritsa kwa weld nugget. Mlingo wa kuwonongeka kwamakono ukhoza kusinthidwa kuti ukhale wozizira bwino komanso kuteteza kutentha kwakukulu kumadera ozungulira, kuchepetsa kupotoza ndi kusunga katundu wazinthu.
4. Post-Pulse Current: Muzinthu zina zowotcherera, positi ya pulse imagwiritsidwa ntchito pambuyo pa kuwotcherera komweku komanso kusanawole konse kwapano. Kuthamanga kwaposachedwa kumathandizira kuyeretsa nugget yowotcherera ndikuwongolera mawonekedwe ake amakina polimbikitsa kufalikira kwamphamvu komanso kukonza mbewu. Kutalika ndi kukula kwa post-pulse panopa kungasinthidwe malinga ndi zofunikira zowotcherera.

Kumvetsetsa mapindikidwe akuwotcherera pano pamakina apakati pafupipafupi inverter spot kuwotcherera ndikofunikira kuti mukwaniritse ma weld apamwamba komanso odalirika. Njira yowongolera, kuwotcherera pakali pano, kuwonongeka kwaposachedwa, komanso kugwiritsa ntchito kwaposachedwa kwaposachedwa kumathandizira pakuwotcherera, kuwonetsetsa kuti kutentha kumalowa, kulimba, ndi kuziziritsa. Mwa kukhathamiritsa njira yowotcherera yomwe ilipo potengera zinthu, makulidwe, ndi mawonekedwe omwe amafunidwa, opanga amatha kupeza zotsatira zokhazikika komanso zokhutiritsa pakugwiritsa ntchito kuwotcherera malo.
