Njengoba ukukhiqizwa kwezindiza ezilula kukhula, kwafinyelela umphumela wonyaka wezindiza ezingaphezu kuka-5,000 kanye nokungena kwemali yezindiza ezisuka mpo zikagesi nezihlala phansi (eVTOL) ezingaphezu kwezigidi eziyizinkulungwane eziyi-10 zamadola aseMelika, kubonise ukuthi imboni yezokundiza ingena enkathini yenguquko. Iphakethe lebhethri liwumgogodla walolu shintsho, futhi ukuphepha kwalo, isisindo nokwethembeka kuzonquma ngokuqondile ukuthi kungenzeka yini isizukulwane esilandelayo sendiza. I-Traditional spot welding isetshenziswa kakhulu, kodwa ayikwazi ukuhlangabezana nezidingo eziqinile zomkhakha wamanje wezokundiza othuthukisiwe. Kodwa ubuchwepheshe be-welding ye-transistor buchaza kabusha lo mkhakha.
Amaphakethe ebhethri ebanga lendiza anezidingo zokushisela eziphezulu kakhulu zekhwalithi. I-aluminium yochungechunge oluyisithupha (esetshenziselwa ukunciphisa isisindo), insimbi ye-nickel-plated (esetshenziselwa ukuthuthukisa ukumelana nokugqwala) kanye nezinto eziyinhlanganisela yethusi-aluminium zivelele. Kodwa-ke, imishini yokushisela indawo yendabuko ayikwazi ukuhlangabezana nezidingo zezinto ezingenhla. Ukusatshalaliswa kwamandla okushisela okungalingani kulula ukubangela ukuqhekeka kwe-splash. Ngemuva kokushisela, imiphumela yokuhlolwa kwe-X-ray ibonisa ukuthi kufika ku-30% wama-welds awafanelekile. Indawo yayo ethintekile ekushiseni (HAZ) idlula umkhawulo oqinile ongu-0.2 mm, okuzolimaza ukwakheka kwamakhemikhali ebhethri futhi kusheshise ukubola kwebhethri. Okubi nakakhulu, imishini yokushisela indawo yendabuko ayinakho ukulandeleka kwesikhathi sangempela kwemingcele yengcindezi yokushisela, okwenza inqubo yokuqapha kanye nedatha yokushisela ingabikho. Futhi iwelding transistorimishini ixazulula ngokuphelele leli phuzu lobuhlungu ngokuqapha nokurekhoda idatha yokucindezela yejoyinti ngalinye le-solder ngesikhathi sangempela.
I-Styler Electronic'umshini wokushisela we-transistorixazulula lawa maphuzu ezinhlungu ngokusebenzisa ukulawula kwe-microsecond kanye nokusungula okunembayo kwe-welding. I-inverter yayo engu-20k Hz–200kHz ephezulu ingakwazi ukubona i-waveform yamanje ehlelekayo (DC, ukushaya kwenhliziyo noma irempu), ngaleyo ndlela izuze ukunemba kokushisela okungu-0.05mm. Okungakhuphula ukunemba kwephakethe lebhethri, okubaluleke kakhulu ekuphepheni kwezindiza.
Ukunikezwa kwamandla okushisela i-Transistor kusebenzisa i-IGBT namanye ama-transistor ashintshashintshayo anesivinini esikhulu, angakhipha amanje aqondile aqine kakhulu, futhi athembele kubuchwepheshe be-inverter obunamaza aphezulu (obufana no-20kHz) ukuze kutholakale ukulawula okunembile kwezinhlelo zamagagasi amanje. Umnyombo wawo usekucindezelweni okuhlelekile kweziphambeko zokushisela ngokusebenzisa inqubo ephelele yokulandelana “yokwenyuka kancane kancane komthambeka-obushelelezi wokushisela-ukwehla kancane kancane”. Ngesikhathi esifanayo, i-microprocessor eyakhelwe ekunikezeni amandla iqapha amandla amanje kanye ne-voltage ngesikhathi sangempela ku-microsecond frequency, futhi i-welding current "ikhiyiwe" ngokuqinile enani elimisiwe ngokulungisa ngokuguquguqukayo isimo sokushintshwa kwe-IGBT. Ingakwazi ukumelana ngokuphumelelayo nokuphazamiseka okubangelwa ukuguqulwa okuguquguqukayo kokumelana nenqubo ye-welding, ngokuyisisekelo igweme i-splash overheating ebangelwa ukuguqulwa okungazelelwe kwamanje, futhi iqinisekise ukuzinza okwedlulele kokufakwa kokushisa.
I-case study igqamisa izinzuzo zayo. Ijoyinti yensimbi ye-Al-Ni engu-0.3mm-ugqinsi ifinyelela ku-85% wamandla ensimbi eyisisekelo ngaphansi kwezinga le-ASTM E8, futhi ingamelana nokudlidliza okwedlulele. Ukusebenza kahle kwayo kwamandla kuphezulu njengoba kungama-92%. Uma kuqhathaniswa nemishini yokushisela yendabuko, ukusetshenziswa kwamandla kuncishiswa ngo-40%, futhi umugqa ngamunye wokukhiqiza ophakathi nendawo ungagcina ama-dollar angu-12,000 njalo ngonyaka. Ukuthobela okufakwe ngaphambilini kwe-DO-160G kungathuthukisa isivinini sokuthola isitifiketi ngo-30% futhi kusekelwa isitifiketi sobuchwepheshe se-EASA.
Okwabakhiqizi bemishini yoqobo yendiza, abakhiqizi bephakethe lebhethri kanye nelabhorethri ye-R&D, i-Styler'sumshini wokushisela we-transistoridlula ububanzi bamathuluzi wokushisela. Njengesihlangu sokuthobela, iguqula izithiyo zokulawula zibe izinzuzo zokuncintisana. Ukushisela ngakunye kuba yiphuzu ledatha elilandelekayo nelitholakala kalula, elihambisana nezindinganiso ze-ISO3834 kanye ne-RTCA DO-160.
Ukushisela okunembayo akuseyona inketho, kodwa kuyisisekelo esinoshintsho lwendiza ephuma ugesi eyehlayo nehlalayo (i-eVTOL) isuka ku-prototype iye emikhunjini yabagibeli. I-Styler imema abakhiqizi ukuthi bathole ukunemba kwe-millimeter ngokubonisa bukhoma. Thola ukuthi ubuchwepheshe bethu bokushisela ibhethri buguqula kanjani ubungozi bube ukwethembeka. Xhumana nathi ukuze uthole imininingwane eyengeziwe futhi ucacise kabusha izindinganiso zakho zokushisela zezindiza, ukuze yonke i-welding izalelwe ukundiza esibhakabhakeni esiluhlaza.
