Kuwotcherera Zotsatira Zokhala ndi Ma Electrodes Osiyanasiyana mu Medium Frequency Inverter Spot Welding

Pakatikati pa ma frequency inverter malo kuwotcherera, kusankha kwa maelekitirodi kumagwira ntchito yofunika kwambiri pakukwaniritsa zomwe mukufuna.Mitundu yosiyanasiyana ya ma elekitirodi imatha kukhala ndi zotsatira zosiyanasiyana pamtundu wa weld, magwiridwe antchito, komanso magwiridwe antchito onse.Nkhaniyi ikufuna kufufuza zotsatira zowotcherera zomwe zimapezedwa ndi ma elekitirodi osiyanasiyana muzowotcherera wapakati pafupipafupi ma inverter spot.

Ma Electrodes a Copper:
Ma elekitirodi amkuwa amagwiritsidwa ntchito kwambiri pakuwotcherera mawanga chifukwa cha matenthedwe awo abwino kwambiri komanso kuchuluka kwamagetsi.Amapereka kutentha kwachangu, zomwe zimapangitsa kutentha ndi yunifolomu ya workpieces.Ma elekitirodi amkuwa amawonetsanso kukana kwabwino kuti asavale ndi kupindika, kuwonetsetsa kuti kuwotcherera kosasintha pakagwiritsidwa ntchito nthawi yayitali.Ma welds omwe amapezedwa ndi ma elekitirodi amkuwa nthawi zambiri amawonetsa mphamvu zabwino, kudalirika, ndi spatter yochepa.
Ma Electrodes a Chromium Zirconium Copper (CuCrZr):
Ma electrode a CuCrZr amadziwika chifukwa cha kuuma kwawo kowonjezereka komanso kukana kumamatira kwa ma elekitirodi.Kuphatikizika kwa chromium ndi zirconium kumapangitsa kuti ma elekitirodi apangidwe bwino, kumachepetsa chizolowezi choti chitsulo chosungunula chimamatire ndi electrode pamwamba pa kuwotcherera.Izi zimachepetsa kuipitsidwa kwa ma elekitirodi, kumawonjezera moyo wa ma electrode, ndikuwonjezera mawonekedwe ake.Ma welds opangidwa ndi maelekitirodi a CuCrZr nthawi zambiri amawonetsa kutsirizika kwapamwamba komanso kuchepa kwa ma elekitirodi.
Refractory Electrodes (mwachitsanzo, Tungsten Copper):
Ma elekitirodi okana, monga mkuwa wa tungsten, amasankhidwa kuti agwiritse ntchito kuwotcherera komwe kumaphatikizapo kutentha kwambiri kapena zinthu zovuta.Ma elekitirodi awa amapereka kukana kutentha kwambiri komanso kulimba, kuwapangitsa kukhala oyenera kuwotcherera omwe amafunikira kutentha kwanthawi yayitali kapena kuphatikiza zida zokhala ndi malo osungunuka kwambiri.Ma elekitirodi a refractory amatha kupirira zovuta zowotcherera ndikusunga magwiridwe antchito, zomwe zimapangitsa kuti ma welds odalirika azikhala ndi ma elekitirodi ochepa.
Ma Electrodes Ophatikizidwa:
Maelekitirodi okutidwa amapangidwa kuti azipereka magwiridwe antchito kapena kuthana ndi zovuta zina zowotcherera.Mwachitsanzo, maelekitirodi okhala ndi zokutira zapadera amatha kulimbitsa kukana kumamatira, kuchepetsedwa kwa spatter, kapena chitetezo chowonjezera pakuvala.Zopaka izi zitha kupangidwa ndi zinthu monga siliva, faifi tambala, kapena ma aloyi ena, opangidwa kuti akwaniritse zofunikira zowotcherera.Maelekitirodi okutidwa amatha kupangitsa kuti mawonekedwe a weld awoneke bwino, kuchepa kwa zilema, komanso kutalika kwa moyo wa ma elekitirodi.
Ma Electrodes Ophatikiza:
Maelekitirodi ophatikizika amaphatikiza zida zosiyanasiyana kuti athandizire zabwino zawo.Mwachitsanzo, ma elekitirodi ophatikizika amatha kukhala ndi mkuwa wozunguliridwa ndi wosanjikiza wa zinthu zokanizira.Kapangidwe kameneka kakuphatikiza phindu la matenthedwe apamwamba kwambiri kuchokera ku mkuwa komanso kukana kwambiri kutentha kuchokera kuzinthu zokanira.Maelekitirodi ophatikizika amapereka mgwirizano pakati pa magwiridwe antchito ndi kutsika mtengo, kupereka zotsatira zodalirika zowotcherera pamapulogalamu osiyanasiyana.
Kusankhidwa kwa ma elekitirodi mu sing'anga ma frequency inverter spot kuwotcherera kumakhudza kwambiri zotsatira zowotcherera.Ma elekitirodi amkuwa amagwiritsidwa ntchito kwambiri chifukwa cha matenthedwe ake abwino komanso magetsi.Ma electrode a CuCrZr amapereka kulimba kwabwino komanso kutsika kwa ma elekitirodi.Ma elekitirodi a refractory ndi oyenera kugwiritsa ntchito kutentha kwambiri, pomwe ma elekitirodi ophimbidwa amapereka magwiridwe antchito apadera.Ma electrode ophatikizika amaphatikiza zida zosiyanasiyana kuti akwaniritse magwiridwe antchito.Posankha maelekitirodi oyenerera kutengera zofunikira zowotcherera, opanga amatha kukwaniritsa mtundu womwe amafunidwa, kukonza magwiridwe antchito, komanso magwiridwe antchito apakati pafupipafupi ma inverter spot kuwotcherera.
