I-Medium frequency spot welding iyindlela esetshenziswa kakhulu ezimbonini zokukhiqiza yokuhlanganisa izingxenye zensimbi ndawonye. Isigaba esisodwa esibalulekile ekusebenzeni kwe-medium frequency spot welder yisigaba sokushisisa samandla. Kulesi sigaba, imishini yokushisela ihambisa inani elilawulwayo lamandla kagesi kuma-workpieces, okwenza indawo yendawo yokushisa okukhulu ezindaweni zokuthintana.
Ngesikhathi sesigaba sokushisisa samandla, i-medium frequency spot welder isebenzisa i-alternating current (AC) enefrikhwensi esukela ku-1000 kuye ku-10000 Hz. Le frequency ye-AC emaphakathi ikhethwa ngenxa yokuthi yenza ibhalansi phakathi kwezinye izindlela ze-high-frequency kanye ne-low-frequency. Ivumela ukudluliswa kwamandla okuphumelelayo kanye nokulawula okunembile phezu kwenqubo yokushisa.
Isigaba sokushisisa samandla sisebenzela izinjongo ezimbalwa ezibalulekile kunqubo yokushisela indawo. Okokuqala, ishisa izingxenye zensimbi, inciphisa ukushaqeka kokushisa lapho kusetshenziswa umshini wokushisela wangempela. Lokhu kushisisa kancane kancane kunciphisa ukuhlanekezela kwezinto futhi kusiza ukugcina ubuqotho besakhiwo belunga elishiselwe.
Okwesibili, ukushisisa kwendawo kuthambisa izindawo zensimbi, kukhuthaze ukuqhutshwa kagesi okungcono phakathi kwezinto zokusebenza. Lokhu kubalulekile ukuze kuzuzwe i-weld engaguquki futhi enokwethenjelwa. Insimbi ethambile iphinde isize ekususeni ukungcola okungaphezulu njengama-oxides, iqinisekise isixhumi esibonakalayo esihlanzekile.
Ngaphezu kwalokho, isigaba sokushisisa samandla sidlala indima ekuzuzeni ukuguqulwa kwe-metallurgical. Njengoba insimbi ishisa, i-microstructure yayo iyashintsha, okuholela ekuthuthukisweni kwamandla okushisela nokuqina. Lesi sigaba esilawulwayo siqinisekisa ukuthi izakhiwo ezibonakalayo ziyathuthukiswa, kunokuba zibe sengozini.
Ubude besikhathi sesigaba sokushisisa samandla siyahlukahluka ngokuya ngezinto ezifana nohlobo lwensimbi eshiselwayo, ukujiya kwayo, kanye nemingcele efiselekayo yokushisela. Imishini yesimanje ye-medium frequency spot welding ifakwe izinhlelo zokulawula eziyinkimbinkimbi ezilungisa isikhathi sokushisisa nokokufaka kwamandla ngokuya ngezidingo ezithile zomsebenzi wokushisela ngakunye.
Sengiphetha, isigaba sokushisisa samandla kumshini wokushisela amabala aphakathi okuyisinyathelo esibalulekile enqubweni yokushisela. Ishisa kuqala izinto zokusebenza, ithuthukise ukuhamba kukagesi, ihlanze izindawo ezingaphezulu, futhi ifake isandla ekuthuthukisweni kwe-metallurgical. Lesi sigaba sibonisa ukunemba nokuzivumelanisa nezimo kwamasu okukhiqiza esimanje, ukuqinisekisa ukushisela okuqinile nokuthembekile kwezinhlelo zokusebenza eziningi.
