Zida Zamagetsi Zomwe Zimagwiritsidwa Ntchito Pamakina a Nut Spot Welding?

Makina owotchera mawanga a mtedza amagwiritsidwa ntchito kwambiri m'mafakitale ophatikiza mtedza ku zigawo zachitsulo. Kusankhidwa kwa zinthu za elekitirodi ndikofunikira pakukwaniritsa ma welds apamwamba kwambiri ndikuwonetsetsa kuti zida zowotcherera zimatenga nthawi yayitali. Nkhaniyi ikuyang'ana zida zomwe zimagwiritsidwa ntchito kwambiri pamakina owotcherera nati ndi maubwino ake pamakina osiyanasiyana owotcherera.

1. Ma Electrodes a Copper: Ma elekitirodi amkuwa ndi amodzi mwa zosankha zodziwika bwino pamakina owotcherera a mtedza. Copper imapereka ma conductivity abwino kwambiri amafuta komanso kukhathamiritsa kwamagetsi, kupangitsa kuti ikhale yabwino kusamutsa kutentha moyenera panthawi yowotcherera. Maelekitirodi amkuwa amawonetsanso kukana kwabwino komanso kulimba, zomwe zimawapangitsa kupirira kugwiritsidwa ntchito kwanthawi yayitali popanda kupunduka kwakukulu kapena kuwonongeka.
2. Chromium Zirconium Copper (CuCrZr) Electrodes: CuCrZr electrode ndi aloyi yamkuwa yokhala ndi chromium ndi zirconium pang'ono. Aloyiyi imapereka kukana kopitilira muyeso kutentha, kupangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimaphatikizapo kuzungulira kwanthawi yayitali kapena kuwotcherera kwamphamvu. Ma elekitirodi a CuCrZr amapereka kukana kwabwino kwa ma elekitirodi, kumachepetsa kufunika kosintha ma elekitirodi pafupipafupi ndikuchepetsa mtengo.
3. Ma Electrodes a Tungsten Copper (WCu): Ma elekitirodi amkuwa a Tungsten amaphatikiza malo osungunuka kwambiri komanso kuuma kwa tungsten ndi kutenthetsa kwabwino kwa mkuwa. Kuphatikiza kumeneku kumapangitsa kuti maelekitirodi athe kupirira kutentha kwambiri popanda kusintha kwakukulu. Ma elekitirodi a WCu amagwiritsidwa ntchito nthawi zambiri pamakina omwe amafunikira kuwotcherera pamatenthedwe okwera kapena mafunde akulu.
4. Ma Electrodes a Molybdenum (Mo): Ma elekitirodi a Molybdenum ndi chisankho china chodziwika bwino pamakina owotcherera a nati. Amawonetsa malo osungunuka kwambiri komanso matenthedwe abwino kwambiri, kuwapangitsa kukhala oyenera kugwiritsa ntchito kuwotcherera kwa kutentha kwambiri. Ma elekitirodi a Molybdenum nthawi zambiri amakondedwa akamawotchera zinthu zokhala ndi matenthedwe apamwamba, chifukwa amasamutsa bwino kutentha kuti apange ma welds odalirika.
5. Ma Electrodes a Copper Tungsten (CuW): Ma elekitirodi a CuW ndi zinthu zophatikizika zomwe zimakhala ndi mkuwa ndi tungsten. Kuphatikizana kumeneku kumapereka mphamvu yabwino yamagetsi yamagetsi kuchokera ku mkuwa ndi kutentha kwakukulu kwa tungsten. Ma electrode a CuW amagwiritsidwa ntchito pazinthu zomwe zimafuna kuti magetsi azikwera kwambiri komanso kukana kutentha kwambiri.

M'makina owotcherera ma nati, kusankha kwa zinthu za elekitirodi kumagwira ntchito yofunika kwambiri kuti mupeze zotsatira zabwino zowotcherera. Copper, chromium zirconium copper, tungsten copper, molybdenum, ndi copper tungsten ndi zina mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi ma elekitirodi, chilichonse chimapereka maubwino ake pazowotcherera zosiyanasiyana. Kusankha ma elekitirodi oyenerera malinga ndi zofunikira zowotcherera kumapangitsa kuti ma welds azikhala abwino komanso apamwamba kwambiri, zomwe zimathandizira kuti pakhale zokolola zonse komanso magwiridwe antchito a makina owotcherera a nati.
