Emkhakheni we-medium-frequency spot welding ye-DC, indima yengcindezi yokushisela isalokhu iyisihloko esibaluleke kakhulu.Lesi sihloko sicubungula ukubaluleka kwengcindezi yokushisela, imiphumela yayo enqubweni yokushisela, nezici ezidinga ukucatshangelwa ngokucophelela.
Ukushisela kuyinqubo eyinkimbinkimbi ehlanganisa ukuhlanganiswa kwezingcezu ezimbili zensimbi ngokusebenzisa ukushisa nokucindezela.Nakuba ukubaluleka kokushisa kule nqubo kuqashelwa kabanzi, indima yokucindezela kokushisela ngokuvamile ihlala ingaphansi.Ekushiseleni kwendawo ye-DC enemvamisa emaphakathi, ingcindezi esetshenziswa ngesikhathi senqubo yokushisela ingaba nomthelela omkhulu kwikhwalithi nobuqotho bejoyinti lokushisela.
Esinye sezizathu eziyinhloko zokuthi kungani ingcindezi yokushisela ibalulekile ithonya layo ekuxhumaneni kukagesi phakathi kwezinto zokusebenza.Ku-medium-frequency spot welding ye-DC, ukugeleza okuqhubekayo kwamandla aqondile kudlula ezintweni zokusebenza, kudala ukumelana nokukhiqiza ukushisa.Izinga lokuthintana kukagesi phakathi kwama-workpieces lithinteka ngokuqondile ukucindezela okufakwayo.Ukucindezela okunganele kungaholela ekuthinteni kabi kukagesi, okuholela ekushiseni okungalingani kanye nejoyinti lokushisela elibuthakathaka.
Ngaphezu kwalokho, ingcindezi yokushisela idlala indima ebalulekile ekuzuzeni i-weld nugget engaguquki, okuyichibi lensimbi elincibilikisiwe elakhiwe endaweni yokushisela.Ingcindezi isiza ukuqinisekisa ukuthi ama-workpieces abanjwe aqinile ndawonye, okuvumela ukusatshalaliswa okufanayo kokushisa nokucindezela kulo lonke ukujoyina.Lokhu kufana kubalulekile ukuze kukhiqizwe amashisela aqinile, ahlala isikhathi eside ahlangabezana namazinga emboni kanye nezidingo zokuphepha.
Umthelela wengcindezi ye-welding awukhawulelwe kwikhwalithi ye-weld joint.Iphinde ibe nomthelela ekusebenzeni kahle okuphelele kwenqubo yokushisela.Ukucindezela okunganele kungaholela ezikhathini zokushisela ezinde kanye nokwanda kokusetshenziswa kwamandla, ekugcineni kuthinte ukusebenza kahle kwezindleko zokusebenza kokushisela.
Kunezici eziningana okufanele zicatshangelwe lapho kunqunywa ingcindezi ye-welding efanele yesicelo esinikeziwe.Ubukhulu bezinto ezibonakalayo, uhlobo lwensimbi olujoyinwayo, usayizi we-electrode nokuma, nezilungiselelo zomshini wokushisela konke kudlala indima ekuchazeni imingcele efanelekile yokucindezela.Abasebenza ngokushisela kufanele baqeqeshwe ukuze babone izimpawu zokucindezela okunganele noma okudlulele futhi benze izinguquko ezidingekayo ukuze kuzuzwe ikhwalithi yokushisela oyifunayo.
Sengiphetha, ingcindezi yokushisela ibalulekile ngokungangabazeki ekushiseleni kwendawo ye-DC ye-medium-frequency.Kuthinta ngqo ukuthintana kukagesi, ukwakheka kwe-weld nugget, kanye nokusebenza kahle okuphelele kwenqubo yokushisela.Ukuze kuzuzwe ama-welds asezingeni eliphezulu futhi anokwethenjelwa, abaqhubi be-welding kumele baqonde indima yokucindezela nokusebenzisana kwayo nemingcele ehlukahlukene yokushisela.Ngokwenza kanjalo, bangaqinisekisa ukuthi imisebenzi yabo yokushisela ihlangabezana nezindinganiso ezidingekayo futhi bakhiqize amajoyinti aqinile, aqinile.
