Isikhathi sokushisela siyipharamitha ebalulekile emishinini yokushisela indawo ye-inverter ye-medium-frequency enethonya kakhulu ikhwalithi namandla amajoyinti okushisela.Ukuqonda umqondo wesikhathi sokushisela kanye nomthelela wawo enqubweni yokushisela kubalulekile ukuze kuzuzwe imiphumela emihle.Kulesi sihloko, sizohlola imininingwane yesikhathi sokushisela ku-medium-frequency inverter spot welding.
- Incazelo Yesikhathi Sokushisela: Isikhathi sokushisela sibhekisela esikhathini lapho i-welding current igeleza ngayo ezintweni zokusebenza, idala ukushisa okudingekayo ukuze kuzuzwe ukuhlanganisa nokwenza inhlanganisela ye-weld eqinile.Ngokuvamile kukalwa ngama-millisecond noma imijikelezo, kuye ngezicaciso zomshini wokushisela.Isikhathi sokushisela sihlanganisa isikhathi sokushisa, isikhathi sokubamba, nesikhathi sokupholisa, ngasinye sisebenzela injongo ethile enqubweni yokushisela.
- Isikhathi Sokushisa: Isikhathi sokushisa yisigaba sokuqala sokushisela lapho i-welding current isetshenziswa ezintweni zokusebenza.Ngalesi sikhathi, ukushisa okukhiqizwa okwamanje kubangela ukuthi izinto ezisetshenziswayo zifinyelele izinga lokushisa elifunayo lokuhlanganisa.Isikhathi sokushisisa sincike ezintweni ezifana nobukhulu bezinto ezibonakalayo, ukuqhutshwa kukagesi, kanye nokungena kwe-weld oyifunayo.Kubalulekile ukusetha isikhathi sokushisisa esifanelekile ukuze uqinisekise ukufaka okwanele kokushisa ukuze kuhlanganiswe kahle ngaphandle kokushisisa ngokweqile.
- Isikhathi sokubamba: Ngemva kwesigaba sokushisa, isikhathi sokubamba silandela, lapho kugcinwa khona i-welding ukuze kuvunyelwe ukushisa kusakazwe ngokulinganayo futhi kuqinisekiswe ukuhlanganisa okuphelele.Isikhathi sokubamba sivumela ukuqina kwensimbi encibilikisiwe kanye nokwakhiwa kwesibopho esiqinile se-metallurgical phakathi kwezinto zokusebenza.Ubude besikhathi sokubamba bunqunywa izakhiwo zezinto ezibonakalayo, ukwakheka okuhlangene, kanye nokucaciswa kokushisela.
- Isikhathi Sokupholisa: Uma isikhathi sokubamba sesiphelile, isikhathi sokupholisa siyaqala, lapho ijoyinti le-weld liphola kancane kancane futhi liqina.Isikhathi sokupholisa sibalulekile ekudambiseni ukucindezeleka okusalelayo nokuvimbela ukuhlanekezela noma ukuqhekeka esakhiweni esishiselwe.Kunqunywa izakhiwo ezibonakalayo kanye nobukhulu, kanye nezidingo ezithile zohlelo lwe-welding.
- Ukunqunywa Okufanelekile Kwesikhathi Sokushisela: Ukuthola ikhwalithi yokushisela efanele kudinga ukukhetha isikhathi esifanele sokushisela sohlelo ngalunye oluthile.Izinto ezifana nohlobo lwempahla, ukujiya, ukumiswa okuhlanganyelwe, namandla okushisela afiswayo kufanele kubhekwe.Isikhathi sokushisela singanqunywa ngokuhlolwa kwe-empirical, kusetshenziswa amasampula e-weld nokuhlola izakhiwo zawo zemishini.Ukwengeza, ukuqapha inqubo kanye nempendulo evela ezinzwa kunganikeza ulwazi olubalulekile ukulungisa kahle isikhathi sokushisela nokuqinisekisa ikhwalithi yokushisela engaguquki.
Isikhathi sokushisela sidlala indima ebalulekile enqubweni yokushisela indawo ye-inverter ye-medium-frequency, ibe nomthelela ngokuqondile kwikhwalithi namandla amajoyinti okushisela.Ngokuqonda umqondo wesikhathi sokushisela kanye nezingxenye zayo (isikhathi sokushisa, isikhathi sokubamba, nesikhathi sokupholisa), opharetha bangakwazi ukwandisa imingcele yokushisela ukuze bathole imiphumela emihle.Ukulinganisa ubude besigaba ngasinye nokucabangela izakhiwo zezinto ezibonakalayo kanye nezidingo ezihlanganyelwe kuyisihluthulelo sokukhiqiza ama-welds athembekile nasezingeni eliphezulu ekusetshenzisweni kokushisela indawo ye-inverter ye-medium-frequency.
