Izimbangela zokungaphelele kwe-Fusion ku-Medium-Frequency Inverter Spot Welding?

Ukuhlanganisa okungaphelele, okuvame ukwaziwa ngokuthi “i-cold weld” noma “ukuntuleka kokuhlanganisa,” yinkinga ebucayi engenzeka phakathi nezinqubo zokushisela amabala kusetshenziswa imishini yokushisela i-medium-frequency inverter spot.Kubhekiselwa esimweni lapho insimbi encibilikisiwe ihluleka ukuhlangana ngokugcwele nezinto eziyisisekelo, okuholela ekuhlanganyeleni okushisela okubuthakathaka nokungathembeki.Lesi sihloko sihlose ukuhlola izici ezihlukahlukene ezingaholela ekuhlanganisweni okungaphelele ku-medium-frequency inverter spot welding.

1. I-Welding Yamanje Enganele: Esinye sezizathu eziyinhloko zokuhlanganisa okungaphelele ukungonela ukushisela okwamanje.Uma i-welding current iphansi kakhulu, ingase ingakhiqizi ukushisa okwanele ukuze incibilikise into eyisisekelo ngokwanele.Ngenxa yalokho, insimbi encibilikisiwe ayingeni futhi ixube kahle, okuholela ekuhlanganiseni okungaphelele endaweni esibonakalayo yokushisela.
2. I-Electrode Force enganele: Amandla e-electrode anganele nawo angaba nomthelela ekuhlanganisweni okungaphelele.Amandla e-electrode afaka ingcindezi kuma-workpieces, ukuqinisekisa ukuthintana okufanele nokungena ngesikhathi senqubo yokushisela.Uma amandla e-electrode ephansi kakhulu, kungase kube khona indawo yokuxhumana enganele kanye nokucindezela, okuvimbela ukwakheka kwesibopho esiqinile phakathi kwezinto eziyisisekelo kanye nensimbi encibilikisiwe.
3. Ukuqondanisa Kwe-Electrode Okungalungile: Ukuqondanisa okungalungile kwe-electrode kungabangela ukusabalalisa ukushisa okungalingani futhi, ngenxa yalokho, ukuhlanganisa okungaphelele.Uma ama-electrodes engahambi kahle, ukushisa okukhiqizwa phakathi nenqubo yokushisela kungase kungasatshalaliswa ngokulinganayo kuyo yonke indawo yokushisela.Lokhu kusatshalaliswa kokushisa okungalingani kungaholela ezindaweni ezenziwe zasendaweni zokuhlanganisa okungaphelele.
4. Indawo Engcolisiwe noma Ene-Oxidized: Ukungcola noma i-oxidation ebusweni bezinto zokusebenza kungaphazamisa ukuhlangana okufanele ngesikhathi sokushisela.Ukungcola, okufana namafutha, ukungcola, noma ama-coatings, kusebenza njengemingcele phakathi kwensimbi encibilikisiwe nento eyisisekelo, evimbela ukuhlangana.Ngokufanayo, i-oxidation ebusweni yakha ungqimba lwe-oxide oluthiya ukubopha nokuhlangana okufanele.
5. Isikhathi sokushisela esinganele: Isikhathi sokushisela esinganele singavimbela insimbi encibilikisiwe ukuthi ingagelezi ngokugcwele futhi ihlangane nezinto eziyisisekelo.Uma isikhathi sokushisela sisifushane kakhulu, insimbi encibilikisiwe ingase iqine ngaphambi kokuzuza ukuhlanganisa okuphelele.Lokhu kubopha okunganele kubangela ukushisela okubuthakathaka nokungathembeki.

Ukuqonda izici ezinomthelela ekuhlanganiseni okungaphelele ekushiseleni kwendawo ye-inverter-frequency medium-frequency kubalulekile ekuqinisekiseni amajoyinti okushisela ekhwalithi ephezulu.Ngokubhekana nezindaba ezinjengokunganele kwe-welding yamanje, amandla e-electrode anganele, ukuqondana kahle kwe-electrode, izindawo ezingcolile noma ezine-oxidized, kanye nesikhathi sokushisela esinganele, abakhiqizi banganciphisa ukuvela kokuhlanganisa okungaphelele futhi bathuthukise ikhwalithi yokushisela iyonke.Ukusebenzisa imingcele yokushisela efanele, ukugcina isimo se-electrode, ukuqinisekisa izindawo ezihlanzekile nezilungiswe kahle, nokwandisa isikhathi sokushisela kuyizinyathelo ezibalulekile zokunciphisa ubungozi bokuhlanganisa okungaphelele kanye nokuzuza ukushisela okuqinile nokuthembekile.
