Zofunikira pa Zida za Electrode mu Makina Owotcherera a Nut Spot?

Ma elekitirodi amagwira ntchito yofunika kwambiri pamakina owotcherera ma nati pomwe amathandizira kuyenda kwamagetsi ndikuwonetsetsa kutentha koyenera kuti apange ma weld odalirika komanso olimba.Kusankhidwa kwa zinthu za elekitirodi ndikofunikira kuti zikwaniritse zofunikira zenizeni ndikukwaniritsa ntchito yabwino yowotcherera.Nkhaniyi ikupereka chidule cha zofunikira zomwe ma elekitirodi amayenera kukwaniritsa pamakina owotcherera ma nati.

1. Mayendedwe a Magetsi: Chimodzi mwazinthu zofunika kwambiri pazida za electrode ndichokwera kwambiri kwamagetsi.Kuyenda bwino kwapano ndikofunikira kuti pakhale kutentha koyenera kusungunula chitsulo ndikupanga weld wamphamvu.Zipangizo zokhala ndi machulukidwe abwino kwambiri, monga ma aloyi amkuwa ndi amkuwa, amagwiritsidwa ntchito kwambiri popangira ma elekitirodi owotcherera a nati.
2. Thermal Conductivity: Good matenthedwe madutsidwe khalidwe linanso lofunika ma elekitirodi zipangizo.Zimapangitsa kuti kutentha kwabwino kuwonongeke, kuteteza kutentha kwakukulu komanso kuchepetsa chiopsezo cha kuwonongeka kwa electrode kapena kuwonongeka.Zida zokhala ndi matenthedwe apamwamba, monga mkuwa, zimathandizira kuti kutentha kukhale kokhazikika komanso kutalikitsa moyo wa elekitirodi.
3. Valani Kukaniza: Zida za elekitirodi ziyenera kuwonetsa kukana kwamphamvu kuti zipirire kukhudzana mobwerezabwereza ndi kukakamizidwa panthawi yowotcherera.Kukangana kosalekeza ndi kupanikizika kungayambitse kuwonongeka kwa electrode kapena kuwonongeka kwa pamwamba pa nthawi.Kusankha zinthu zokhala ndi kukana kuvala bwino, monga copper-chromium kapena copper-zirconium alloys, kumatha kukulitsa kulimba kwa electrode ndikuchepetsa kufunikira kosintha pafupipafupi.
4. Kukana kwa dzimbiri: Popeza kuwotcherera mawanga a mtedza nthawi zambiri kumaphatikizapo kugwiritsa ntchito zoziziritsa kukhosi zochokera m'madzi kapena zimachitika m'malo okhala ndi chinyezi chambiri, zida za elekitirodi ziyenera kukhala ndi mphamvu zolimbana ndi dzimbiri.Kuwonongeka kumatha kuwononga ma elekitirodi pamwamba, kukhudza makonzedwe ake amagetsi ndi matenthedwe komanso kusokoneza mtundu wa weld.Zida monga copper-nickel kapena copper-chromium-zirconium alloys amapereka kukana kwa dzimbiri, kuonetsetsa moyo wautali wa electrode.
5. Kuthekera: Zida zama elekitirodi ziyenera kukhala zosinthika mosavuta kuti zipange maupangiri olondola komanso owoneka bwino a elekitirodi.Kuthekera kumatanthawuza kumasuka komwe kungadulidwe, kupangidwa, kapena kupangidwa.Katunduyu ndi wofunikira kuti mukwaniritse mawonekedwe a electrode geometry ndikuwonetsetsa kukhudzana kofanana ndi malo ogwirira ntchito.Copper ndi ma alloys ake amadziwika chifukwa cha makina awo abwino kwambiri, kulola kupanga ma elekitirodi molondola.
6. Kutsika mtengo: Pokwaniritsa zofunikira pakugwira ntchito, zida za electrode ziyeneranso kukhala zotsika mtengo.Kulinganiza zinthu zomwe mukufuna ndi mtengo wazinthu ndikofunikira kuti muwongolere bwino ntchito yonse yowotcherera komanso zokolola.Copper ndi ma alloys ake amalumikizana bwino pakati pa magwiridwe antchito ndi mtengo wake, zomwe zimapangitsa kukhala zosankha zodziwika bwino za zida zowotcherera ma elekitirodi.

Kusankha ma elekitirodi oyenera ndikofunikira kuti mukwaniritse ma welds apamwamba kwambiri pamakina a nati.Zipangizo zama elekitirodi ziyenera kuwonetsa kukhathamiritsa kwakukulu kwamagetsi ndi kutentha, kukana kuvala, kukana dzimbiri, machinability, komanso kukwera mtengo.Copper ndi ma aloyi ake, chifukwa cha kuphatikiza kwawo kwabwino, amagwiritsidwa ntchito kwambiri popangira zida zowotcherera nati.Kusankha zinthu zoyenera zama elekitirodi kumatsimikizira magwiridwe antchito odalirika, kumatalikitsa moyo wa ma elekitirodi, ndipo kumathandizira kuti magwiridwe antchito azitha kugwira ntchito bwino.
