Ubudlelwano Phakathi Kwesikhathi Se-Resistance Spot Welding kanye Nokususwa Kwe-Electrode

I-Resistance spot welding iyindlela esetshenziswa kakhulu ekukhiqizeni, ikakhulukazi ezimbonini zezimoto kanye ne-aerospace, lapho isidingo sokushisela okuqinile nokuthembekile sibaluleke kakhulu. Le nqubo ihilela ukusetshenziswa kwamandla kagesi kanye nengcindezi yokuhlanganisa izingcezu ezimbili zensimbi ndawonye. Ipharamitha eyodwa ebalulekile ekushiseleni kwendawo yokumelana isikhathi sokushisela, esidlala indima ebalulekile ekunqumeni ikhwalithi namandla e-weld. Kulesi sihloko, sizohlola ubudlelwano obuyinkimbinkimbi phakathi kwesikhathi sokushisela kanye nokususwa kwe-electrode, sikhanyise izici ezithonya lokhu kuguquguquka.

I-Resistance spot welding, evame ukubizwa ngokuthi i-spot welding, iyinqubo yokuhlanganisa encike ekusetshenzisweni kwendawo yokushisa okukhiqizwa ukumelana nogesi lapho kuhlangana khona izingcezu ezimbili zensimbi. Ama-Electrode asetshenziselwa ukufaka ingcindezi kanye namanje ukuze enze i-weld nugget. Ubude bokugeleza kwamanje, okwaziwa ngokuthi isikhathi sokushisela, kuyisici esibalulekile ekuphumeleleni kwenqubo yokushisela.

Isikhathi Sokushisela Nomthelela Waso

Isikhathi sokushisela sithinta ngqo ubukhulu kanye nekhwalithi ye-weld nugget. Izikhathi zokushisela ezinde ngokuvamile ziholela ekushiseleni okukhulu futhi andwe kakhulu, kuyilapho izikhathi ezimfushane zikhiqiza ama-weld amancane, angashoni kakhulu. Ubudlelwano phakathi kwesikhathi sokushisela kanye nokugudluzwa kwe-electrode yinkimbinkimbi futhi kuncike ezintweni ezahlukahlukene, kufaka phakathi izakhiwo zezinto ezibonakalayo, i-electrode geometry, kanye ne-welding current.

Izinto Ezithonya Ukususwa Kwe-Electrode

a. Ubukhulu Bezinto:Izinto eziwugqinsi ngokuvamile zidinga izikhathi ezinde zokushisela ukuze kuqinisekiswe ukungena nokuhlangana okufanele. Njengoba isikhathi sokushisela sikhula, ukugudluzwa kwe-electrode nakho kuyanda ukuze kuhambisane nokushisa okwengeziwe nokucindezela okudingekayo.

b. I-Electrode Force:Amandla asetshenziswa ama-electrode athinta ukususwa kwe-electrode. Amandla e-electrode aphezulu angaholela ekuhambeni okusheshayo kwe-electrode ngenxa yokwanda kwengcindezi, okuholela ezikhathini zokushisela ezimfushane.

c. Idizayini ye-Electrode:Ukuma nobukhulu bama-electrode kudlala indima ebalulekile. Imiklamo ehlukene yama-electrode ingase ibe nemiphumela ehlukahlukene ekususweni kwe-electrode, ngisho nangesikhathi esifanayo sokushisela.

d. I-Welding Yamanje:Ukuqina kwamanje kokushisela kuthonya isivinini i-weld nugget yakheka ngaso. Imisinga ephakeme ngokuvamile ibangela ukugudluzwa kwama-electrode ngokushesha kanye nezikhathi zokushisela ezimfushane.

Ukuqonda ubudlelwano phakathi kwesikhathi sokushisela kanye nokususwa kwe-electrode kubalulekile ukuze kuzuzwe ukushisela okungaguquki nokusezingeni eliphezulu. Abakhiqizi bangakwazi ukulawula lobu budlelwano ngokulungisa imingcele yokushisela futhi bakhethe ngokucophelela izinto nemiklamo ye-electrode.

Emkhakheni we-resistance spot welding, ubudlelwano phakathi kwesikhathi sokushisela kanye nokugudluzwa kwe-electrode buyaguquguquka futhi bunezici eziningi. Njengoba sesihlolile, izici ezifana nogqinsi lwezinto, amandla e-electrode, ukwakheka kwe-electrode, namandla okushisela konke kuyasebenza. Ukuphatha lobu budlelwano kubalulekile ekukhiqizeni amashisela athembekile futhi aqinile ezinhlelweni ezihlukene zezimboni. Abacwaningi nonjiniyela bayaqhubeka nokuphenya futhi balungise lokhu kuxhumana ukuze basunduze imingcele yalokho okungenzeka emhlabeni wokushisela indawo.
