Umthelela Wesikhathi Se-Welding Kukhwalithi Ye-Medium Frequency Direct Current Spot Welding

I-Medium frequency direct current spot welding kuyinqubo esetshenziswa kakhulu ezimbonini ezihlukahlukene, njengezezimoto, i-aerospace, ne-electronics, yokuhlanganisa izingxenye zensimbi. Izinga lamajoyinti ashiselwe lidlala indima ebalulekile ekunqumeni ukusebenza okuphelele nokuhlala isikhathi eside komkhiqizo wokugcina. Ipharamitha eyodwa ebaluleke kakhulu ethinta kakhulu ikhwalithi yalezi zinsimbi yisikhathi sokushisela.

Isikhathi sokushisela, kumongo we-medium frequency direct spot welding, sibhekisela esikhathini lapho izingxenye ezimbili zensimbi zingaphansi kwe-welding current. Lesi sikhathi singasukela kumafraktjhini wesekhondi ukuya kumasekhondi ambalwa, ngokuya ngezinto, ukujiya, kanye nesicelo sokushisela. Ukukhethwa kwesikhathi sokushisela kungaba nomthelela omkhulu kukhwalithi yokushisela ewumphumela, futhi ukuqonda lobu budlelwano kubalulekile ukuze kuzuzwe ukushisela okungaguquki nokuthembekile.

Izinto eziyinhloko lapho isikhathi sokushisela sithonya ikhwalithi ye-weld yilezi:

1. Okokufaka Ukushisa:Izikhathi zokushisela ezinde ziphumela ekwenyukeni kokufaka kokushisa endaweni yokushisela. Lokhu kushisa okwengeziwe kungaholela ekuthambiseni ngokweqile kwezinto, okuthinta izakhiwo zemishini zokuhlangana.
2. Ukujula Kokungena:Isikhathi sokushisela sithinta ukujula lapho i-weld current ingena khona ezintweni. Ibhalansi kufanele yenziwe ukuze kuqinisekiswe ukuthi i-current ingena ngokugcwele ejoyintini ngaphandle kokusha ngokweqile noma ukungena okunganele.
3. I-Residual Stress:Izikhathi zokushisela isikhathi eside zingadala amazinga aphezulu engcindezi eyinsalela endaweni yokushisela, okungaholela ezindabeni ezinjengokuhlanekezela, ukuqhekeka, nokunciphisa ukumelana nokukhathala.
4. I-Microstructure:Isikhathi sokushisela sibuye sibambe iqhaza ekunqumeni i-microstructure ye-weld. Izikhathi zokushisela ezinde zingaholela ekwakhiweni kokusanhlamvu okuqinile, okungaba nomthelela ezintweni zokusebenza zelunga.

Ukuze kuthuthukiswe ikhwalithi yokushisela ekushiseleni kwendawo okuphakathi, kubalulekile ukwenza ukuhlola okuphelele nokuhlola ukuze kutholwe isikhathi esifanele sokushisela sohlelo oluthile. Lokhu ngokuvamile kuhilela ibhalansi phakathi kokuzuza ukungena okuhle nokugcina izakhiwo ezifiselekayo zemishini yelunga.

Sengiphetha, isikhathi sokushisela singukuguquguquka okubalulekile kwe-medium frequency direct spot welding, futhi kuba nomthelela omkhulu kwikhwalithi yama-welds. Ukucatshangelwa ngokucophelela isikhathi se-welding, eceleni kweminye imingcele yenqubo, kubalulekile ukufeza izinga eliphezulu, ama-welds athembekile ezinhlobonhlobo zezicelo zezimboni. Ukulawula okufanele nokuqonda isikhathi sokushisela kungaholela ekusebenzeni okuthuthukisiwe komkhiqizo, ukuqina, nokuphepha.
