Ukushisa kwe-Resistance kuyinqubo eyisisekelo emshinini wokushisela we-medium frequency inverter spot, lapho ukumelana kukagesi kwe-workpieces kukhiqiza ukushisa ngesikhathi sokushisela. Lesi sihloko sihlose ukuhlola indlela yokushisisa ukumelana nokuxoxa ngezinto ezihlukahlukene ezithonya ukusebenza kwayo kanye nomthelela enqubweni yokushisela.
- I-Resistance Heating Mechanism: Emishinini yokushisela indawo yokushisela i-frequency inverter, ukudlula kwamandla kagesi aphezulu ngokusebenzisa izinto zokusebenza kudala ukumelana nesixhumi esibonakalayo esihlanganyelwe. Lokhu kumelana kuguqula amandla kagesi abe ukushisa, okuholela ekushiseni kwendawo endaweni yokushisela. Ukushisa okukhiqizwa ukushisisa ukumelana kudlala indima ebalulekile ekuzuzeni ukuhlanganisa okufanele kanye nokwenza i-weld nugget eqinile.
- Izinto Ezithinta Ukushisisa Kokumelana: Izinto eziningi zithonya ukusebenza kokushisisa kokumelana nemishini yokushisela ye-inverter spot ephakathi. Lezi zici zihlanganisa: a. I-Electrical Conductivity: I-conductivity kagesi yezinto zokusebenza ithinta ukumelana futhi, ngenxa yalokho, inani lokushisa elikhiqizwayo. Izinto ezine-conductivity kagesi ephakeme zithola ukumelana okuphansi futhi zivame ukukhiqiza ukushisa okuncane uma kuqhathaniswa nezinto ezinokusebenza okuphansi. b. Ubukhulu Bezinto: Izinto zokusebenza eziwugqinsi zibonisa ukumelana okuphezulu ngenxa yendlela ende yamanje, okuholela ekwandeni kokukhiqizwa kokushisa ngesikhathi sokushisela. c. Ukumelana Nokuxhumana: Izinga lokuthintana kukagesi phakathi kwama-electrode nezinto zokusebenza lithinta kakhulu ukushisa kokumelana. Ukungathintani kahle kuholela ekumelaneni okuphezulu kusixhumi esibonakalayo se-electrode-workpiece, okuholela ekwehleni kokudluliswa kokushisa futhi okungenzeka kuthinte ikhwalithi yokushisela. d. I-Welding Yamanje: Ubukhulu be-welding current buthonya ngokuqondile ukushisa okukhiqizwa ngokushisisa ukumelana. Ama-currents aphezulu akhiqiza ukushisa okwengeziwe, kuyilapho ama-currents aphansi angase abangele ukushisisa okunganele kanye nokwakheka kokushisela okunganele. e. Isikhathi sokushisela: Isikhathi sokusebenza kwe-welding siphinde sithinte ukushisa kokumelana. Izikhathi zokushisela ezinde zivumela ukuthi kukhiqizwe ukushisa okwengeziwe, okuholela ekuhlanganiseni okungcono nokushisela okuqinile. Kodwa-ke, izikhathi zokushisela ezinde ngokweqile zingabangela ukushisa ngokweqile kanye nokulimala okungaba khona ezintweni zokusebenza. f. I-Electrode Force: Amandla asetshenziswayo phakathi kwama-electrode athinta ukuthintana kukagesi futhi, kamuva, ukushisa kokumelana. Amandla e-electrode anele aqinisekisa ukuthintana okufanele kanye nokudluliswa kokushisa okuphumelelayo, okunikela ekuthuthukisweni kwekhwalithi yokushisela.
- Umthelela Wokushisa Okuphikisayo: Ukushisa kokumelana kunomthelela oqondile enqubweni yokushisela kanye nekhwalithi ye-weld ewumphumela. Imiphumela esemqoka ihlanganisa: a. Ukukhiqiza Ukushisa: Ukushisa kokumelana kunikeza amandla ashisayo adingekayo ukuze kuncibilike izinto zokusebenza, ukwenza kube lula ukuhlangana kanye nokwakheka kwe-weld nugget. b. Ukuthambisa Kwezinto Ezibalulekile: Ukushisisa okwasendaweni okuvela ekushiseni kokumelana kuthambisa izinto zokusebenza, okuvumela ukuguquguquka kwepulasitiki futhi kuthuthukise ukubopha kwe-interatomic endaweni ehlangene. c. Indawo Ethintekile Ukushisa (HAZ): Ukushisa okukhiqizwa ngesikhathi sokushisisa ukumelana nakho kuthinta impahla ezungezile, okuholela ekwakhekeni kwendawo ethintekile ekushiseni (HAZ) ebonakala ngesakhiwo esincane esishintshile kanye nezakhiwo zemishini. d. Ukungena Kwe-Weld: Inani lokushisa elikhiqizwa ngokushisisa ukumelana lithonya ukujula kokungena kwe-weld. Ukulawula kahle okokufaka ukushisa kuqinisekisa ukungena okwanele ngaphandle kokuncibilika ngokweqile noma ukushiswa.
Isiphetho: Ukushisa okumelana nakho kuyinqubo eyisisekelo emshinini wokushisela we-medium frequency inverter spot, odlala indima ebalulekile ekuzuzeni ukuhlanganisa okufanele nokwenza amashisela aqinile. Ukuqonda indlela yokushisa yokumelana nokucabangela izici ezithonyayo, njengokuhamba kukagesi, ukushuba kwezinto, ukumelana nokuxhumana, i-welding yamanje, isikhathi se-welding, kanye namandla e-electrode, kunika amandla ukulawulwa okuphumelelayo kwenqubo yokushisela futhi iqinisekisa ikhwalithi ye-weld efiselekayo nokusebenza. Ngokuthuthukisa ukushisisa kokumelana, abakhiqizi bangathuthukisa ukusebenza kahle, ukuthembeka, nokungaguquguquki kokusebenza kwe-spot welding ezinhlelweni ezahlukahlukene zezimboni.
