Medium frequency spot welding inzira inoshandiswa zvakanyanya mumaindasitiri ekugadzira ekubatanidza masimbi masimbi pamwechete. Chimwe chikamu chakakosha mukushanda kwepakati frequency spot welder ndiyo simba-pakupisa chikamu. Muchikamu chino, midziyo yewelding inopa huwandu hunodzorwa hwesimba remagetsi kune zvishandiso zvebasa, zvichigadzira nzvimbo yenzvimbo yekupisa kwakanyanya panzvimbo dzekusangana.
Munguva yesimba-pakudziya chikamu, yepakati frequency spot welder inoshandisa alternating current (AC) ine frequency inotangira pa1000 kusvika 10000 Hz. Iyi yepakati frequency AC inosarudzwa nekuti inobata chiyero pakati peyepamusoro-frequency uye yakaderera-frequency dzimwe nzira. Inobvumira kushandiswa kwesimba kunobudirira uye kutonga kwakarurama pamusoro pekupisa.
Iyo simba-pakupisa chikamu chinoshandira zvakati wandei zvakakosha mune iyo nzvimbo welding process. Chekutanga, inopisa mativi esimbi, ichideredza kuvhunduka kwekupisa kana iyo chaiyo welding ikozvino inoshandiswa. Uku kudziyisa zvishoma nezvishoma kunoderedza kukanganiswa kwezvinhu uye kunobatsira kuchengetedza kurongeka kwechimiro chejoini yakasungwa.
Chechipiri, kupisa kwenzvimbo kunonyorovesa nzvimbo dzesimbi, kusimudzira zvirinani magetsi conductivity pakati pezvishandiso. Izvi zvakakosha pakuwana inowirirana uye yakavimbika weld. Iyo simbi yakapfava inobatsirawo kubvisa zvinosvibisa pamusoro senge oxides, kuve nechokwadi chekuchenesa welding interface.
Uyezve, iyo simba-pakupisa chikamu chinoita basa mukuzadzisa metallurgical shanduko. Sezvo simbi inopisa, microstructure yayo inoshanduka, zvichiita kuti iwedzere simba re weld uye kusimba. Ichi chinodzorwa chikamu chinovimbisa kuti zvinhu zvenyama zvinowedzerwa, pane kukanganiswa.
Nguva yesimba-pakupisa chikamu chinosiyana zvichienderana nezvinhu zvakaita semhando yesimbi iri kushiswa, ukobvu hwayo, uye inodiwa welding paramita. Yemazuva ano yepakati frequency spot welding michina yakashongedzerwa neyakaomesesa yekudzora masisitimu anogadzirisa nguva yekudziya uye simba rekuisa zvinoenderana nezvinodiwa zvega ega welding.
Mukupedzisa, simba-pakupisa chikamu mune yepakati frequency spot welder inhanho yakakosha mukuita welding. Inopisa maworkpieces, inosimudzira conductivity yemagetsi, inochenesa nzvimbo, uye inobatsira mukuvandudzwa kwesimbi. Ichi chikamu chinoratidza kurongeka uye kuchinjika kwemaitiro emazuva ano ekugadzira, kuve nechokwadi chesimba rakasimba uye rakavimbika welds yemhando dzakasiyana dzekushandisa.
