Resistance spot welding ndi njira yomwe imagwiritsidwa ntchito kwambiri popanga zomwe zimaphatikizapo kulumikiza zitsulo ziwiri kapena kuposerapo pogwiritsa ntchito kutentha ndi kukakamiza pamalo enaake. Kuti izi zitheke bwino, makina owotcherera malo amafunikira gwero lodalirika la mphamvu zamagetsi. M'nkhaniyi, tiwona njira zosiyanasiyana zoperekera magetsi zomwe zimagwiritsidwa ntchito pamakina owotcherera amakani.
- Direct Current (DC) Magetsi:
- Mphamvu ya DC ndiyo njira yodziwika bwino komanso yachikhalidwe yomwe imagwiritsidwa ntchito powotcherera malo okana. Iwo amapereka ulamuliro yeniyeni pa magawo kuwotcherera.
- Mu kuwotcherera mawanga a DC, mphamvu yachindunji imadutsa maelekitirodi owotcherera. Izi zimatulutsa kutentha pamalo owotcherera, zomwe zimapangitsa kuti chitsulo chisungunuke ndikuphatikizana.
- Alternating Current (AC) Magetsi:
- Magetsi a AC sagwiritsidwa ntchito nthawi zambiri koma amakhala ndi zabwino zake, makamaka pamapulogalamu omwe amafunidwa kuwotcherera mofewa.
- AC malo kuwotcherera kumapereka yunifolomu Kutentha kwenikweni, zomwe zingachepetse chiopsezo cha kutenthedwa ndi warping mu zipangizo zina.
- Ma Inverter-based Power Supply:
- Tekinoloje ya inverter yakhala yotchuka kwambiri pamakina owotchera malo okana chifukwa champhamvu zake komanso kusinthasintha.
- Magetsi opangidwa ndi ma inverter amasintha mphamvu ya AC yomwe ikubwera kukhala yoyendetsedwa ndi DC, ndikupereka zabwino zonse za DC ndi AC kuwotcherera.
- Capacitor Discharge Welding (CDW):
- CDW ndi njira yapadera yoyenera kuwotcherera mopepuka komanso pang'ono.
- Mu CDW, mphamvu imasungidwa mu banki ya capacitor ndiyeno imatulutsidwa mwachangu kudzera mu ma electrode owotcherera, ndikupanga arc yachidule koma yolimba kwambiri.
- Kuwotcherera kwa Pulsed:
- Kuwotcherera kwa pulsed ndi luso lamakono lomwe limaphatikiza ubwino wa DC ndi AC kuwotcherera.
- Zimaphatikizapo kuphulika kwa mphamvu kwapang'onopang'ono komwe kumalola kuwongolera bwino njira yowotcherera ndikuchepetsa kulowetsa kwa kutentha.
- Kuwotcherera kwa Inverter Yapakatikati:
- Njirayi imagwiritsidwa ntchito kwambiri popanga magalimoto komanso ntchito zina zowotcherera zothamanga kwambiri.
- Kuwotcherera kwapakati pafupipafupi kumapereka kusamutsa mphamvu mwachangu, kumachepetsa nthawi yonse yowotcherera malo.
Iliyonse mwa njira zoperekera mphamvuzi zili ndi mphamvu ndi zofooka zake, zomwe zimawapangitsa kukhala oyenera kugwiritsa ntchito zowotcherera. Kusankhidwa kwa magetsi kumatengera zinthu monga mtundu wa zida zomwe zimawotcherera, mtundu womwe mukufuna, liwiro lopanga, komanso zofunikira pakuwongolera mphamvu.
Pomaliza, makina owotcherera amakaniza amatha kuyendetsedwa ndi njira zosiyanasiyana, iliyonse ikupereka maubwino apadera kuti akwaniritse zosowa zosiyanasiyana zamakampani opanga mafakitale. Kusankhidwa kwa njira yoyenera yoperekera magetsi ndikofunikira pakuwonetsetsa kuti ntchito yowotcherera mawanga ndi yabwino komanso yabwino.
