Pokhapokha podziwa momwe njira yowotcherera imakhudzira kuwotcherera, ndi pomwe tingathe kugwiritsa ntchito bwino ndikukonzamakina opangira chitoliro okhala ndi msoko wautali kwambirikuti tikwaniritse bwino kwambiri. Tiyeni tiwone momwe njira zowotcherera zimakhudzira makina owotcherera mapaipi oyenda molunjika omwe amagwiritsidwa ntchito pafupipafupi masiku ano.
Pali njira ziwiri zakuwotcherera kwapamwamba kwambiri: kulumikiza cholumikizira ndi cholumikizira cholumikizira.
Kulumikiza magetsi pogwiritsa ntchito ma electrode awiri amkuwa omwe amalumikizana ndi mbali zonse ziwiri za chitoliro chachitsulo kuti chilumikizidwe. Mphamvu yoyambitsidwa imalowa bwino. Zotsatira ziwiri za mphamvu yapamwamba zimawonjezeka chifukwa cha kukhudzana mwachindunji pakati pa ma electrode amkuwa ndi mbale yachitsulo. Chifukwa chake, mphamvu yolumikizira magetsi pogwiritsa ntchito ma contact welding ndi yapamwamba kwambiri ndipo imagwiritsa ntchito mphamvu zochepa, imagwiritsidwa ntchito kwambiri popanga mapaipi othamanga kwambiri komanso otsika, ndipo kulumikiza magetsi pogwiritsa ntchito ma contact welding nthawi zambiri kumafunika popanga mapaipi okhuthala kwambiri achitsulo. Komabe, pali zovuta ziwiri pakulumikiza magetsi pogwiritsa ntchito ma contact welding: choyamba ndichakuti ma electrode amkuwa amalumikizana ndi mbale yachitsulo, ndipo amawonongeka mwachangu; china ndichakuti chifukwa cha kusalala kwa pamwamba pa mbale yachitsulo ndi kuwongoka kwa m'mphepete, kukhazikika kwa magetsi pogwiritsa ntchito ma contact welding ndi koipa, ndipo ma burrs amkati ndi akunja a weld ndi okwera. , Nthawi zambiri sagwiritsidwa ntchito polumikiza mapaipi olondola kwambiri komanso opyapyala.
Kuwotcherera kwa induction ndi kukulunga ma coil olowera kutembenuka kamodzi kapena kangapo kunja kwa chitoliro chachitsulo kuti chiwotchulidwe. Zotsatira za kutembenuka kambiri zimakhala bwino kuposa kutembenuka kamodzi, koma zimakhala zovuta kwambiri kupanga ndikuyika ma coil olowera kutembenuka kambiri. Kuchita bwino kumakhala kwakukulu pamene mtunda pakati pa coil yolowera ndi pamwamba pa chitoliro chachitsulo ndi wochepa, koma n'zosavuta kuyambitsa kutulutsa pakati pa coil yolowera ndi chitoliro. Nthawi zambiri, ndibwino kusunga mpata wa 5-8 mm pakati pa coil yolowera ndi pamwamba pa chitoliro chachitsulo. Mukamagwiritsa ntchito chowotcherera cha induction, popeza chowotcherera cha induction sichikukhudzana ndi mbale yachitsulo, palibe kuwonongeka, ndipo mphamvu ya induction imakhala yokhazikika, zomwe zimatsimikizira kukhazikika kwa kuwotcherera. Ubwino wa pamwamba pa chitoliro chachitsulo panthawi yowotcherera ndi wabwino, ndipo msoko wa weld ndi wosalala. Pa mapaipi olondola, chowotcherera cha induction chimagwiritsidwa ntchito makamaka.
