Ukusebenza kokushisela kwe-medium frequency inverter spot welding kudlala indima ebalulekile ekunqumeni ikhwalithi nokuthembeka kwama-welds.Ukulinganisa nokuhlola ukusebenza kwe-welding kubalulekile ukuze kuqinisekiswe imiphumela engaguquki futhi eyanelisayo.Lesi sihloko sihlola ukuthi ukusebenza kokushisela kwe-medium frequency inverter spot welding kungahlolwa kanjani.
Ikhwalithi ye-Weld:
Ikhwalithi ye-Weld iyisilinganiso esiyisisekelo sokusebenza kwe-welding.Kubandakanya ukuhlola ubuqotho nomsindo wejoyinti le-weld.Izinto ezinjengokubukeka kwe-weld, ukungabi bikho kweziphambeko (isb, ukuqina, ukuqhekeka), kanye nokubambelela ezimisweni zokushisela ezicacisiwe kucatshangelwa ekuhlolweni kwekhwalithi yokushisela.
Amandla Weld:
Amandla okuhlangana kwe-weld kuyinkomba ebalulekile yokusebenza kwe-welding.Ikala ikhono le-weld ukumelana nemithwalo esetshenzisiwe futhi imelane nokwehluleka.Ukuhlolwa kwamandla, okufana nokuqina noma ukuhlola ukugunda, kwenziwa ukuze kutholwe ubukhulu bomthwalo noma ingcindezi i-weld engakwazi ukubambelela ngaphambi kokwehluleka.
Ubuqotho be-Weld:
I-Weld integrity isho ukuzwakala kwesakhiwo kanye nensimbi ye-weld.Kubandakanya ukuhlola izici ezifana nezinga lokuhlanganisa, ukungena kwe-weld, kanye nokuhlangana kobuso phakathi kwezinto zokusebenza.Amasu okuhlola angalimazi afana nokuhlola nge-radiographic noma nge-ultrasonic angasetshenziswa ukuze kuhlolwe ubuqotho be-weld.
Izici zikaMechanical:
Izici zemishini ze-weld, ezifaka ubulukhuni, i-ductility, nokuqina, zinikeza imininingwane ekusebenzeni kokushisela.Lezi zakhiwo zinqunywa ngezindlela zokuhlola zemishini, ezinjengokuhlola ubulukhuni noma ukuhlolwa komthelela, ukuze kuqinisekiswe ukuthi i-weld inezici zemishini ezidingekayo.
Ukuhlaziywa kweMicrostructural:
Ukuhlaziywa kwe-Microstructural kuhilela ukuhlola i-weld microstructure ukuhlola ukusebenza kokushisela.Lokhu kuhlaziya kusiza ukukhomba ubukhona bezici ezingathandeki njengokukhula kokusanhlamvu, indawo ethinteke kakhulu ekushiseni (HAZ), noma ukuntuleka kokuhambisana kwe-metallurgical.Amasu e-metallographic, njenge-optical microscopy noma i-electron microscopy, asetshenziswa ekuhloleni okuningiliziwe kwe-microstructural.
Ukuqapha Nokulawula Inqubo:
Ukuqapha nokulawula imingcele yenqubo yokushisela kubalulekile ekuhloleni ukusebenza kwe-welding.Amapharamitha anjengamanje, i-voltage, amandla e-electrode, nesikhathi sokushisela aqashwa ngokuqhubekayo ukuze kuqinisekiswe ukuthi angaphakathi kwebanga elishiwo.Ukuchezuka kumapharamitha afunekayo kungabonisa izinkinga ezingaba khona ezithinta ukusebenza kokushisela.
Ukusebenza kokushisela kwe-medium frequency inverter spot welding kungahlolwa ngemibandela eminingi, okuhlanganisa ikhwalithi ye-weld, amandla e-weld, ubuqotho be-weld, izakhiwo zemishini, ukuhlaziywa kwe-microstructural, kanye nokuqapha inqubo.Ngokuhlola lezi zici, abakhiqizi nabaqhubi banganquma ukusebenza kahle nokuthembeka kwenqubo yokushisela futhi bathathe izinyathelo ezidingekayo ukuze kuzuzwe ukusebenza kahle kwe-welding.
