1. Izindlela Eziyinhloko Zokupholisa
Njengoba ukupholisa uketshezi okwamanje kuyindlela eyinhloko yokupholisa amabhethri kagesi/okugcina, ikhwalithi yokucubungula ukushisela amapuleti okupholisa uketshezi ibaluleke kakhulu. Kuthinta ngqo ukusebenza kanye nokusebenza kahle kokushabalalisa ukushisa kwe-amapuleti okupholisa oketshezi.
2. Amaphutha Ezindlela Zendabuko
Izindlela zokushisela zendabukoamapuleti okupholisa amanziNgokuyisisekelo zihlukaniswe kanje: ukushisela okushukumisayo kwe-friction (FSW), ukushisela nge-vacuum, ukushisela nge-argon arc, njll. Izindlela zokushisela zendabuko zinezinzuzo kanye nokungalungi: I-FSW ingashisela izingxenye ezinkulu, futhi amandla ayo okushisela angama-70% ezinto eziyisisekelo. Ukushisela kufanelekela ukukhiqizwa ngobuningi. Kodwa-ke, lezi zindlela zokushisela zendabuko zinezinkinga ezithile, njenge-FSW, ukusebenza kahle kokushisela kuphansi, i-weld bead ithambekele ekugoqeni, ikhanda lokuxubha likhulu futhi alikwazi ukwenza ukushisela okunembile, futhi iphuzu elibalulekile liwukuthi (ukuguquguquka kokushisa ngemva kokushisela kukhulu, ukucubungula ngemva kokucubungula kuyakhathaza, kanti izindleko zokucubungula zesibili ziphezulu). Ukushisela nge-vacuum (ukusetshenziswa kwamandla kwesithando somhubhe wokushisela sikhulu kakhulu (cishe ama-yuan ayi-1300 ngesikhathi sebhili kagesi esincane) ijoyinti alinawo ukumelana nokushisa okubi, futhi insimbi yokugcwalisa ithambekele ekuchichimeni, okuholela ekuvinjweni kwesiteshi sokugeleza).
3. Izicelo Zokushisela Nge-Laser
Ukushisela nge-laser ubuchwepheshe bokushisela obunembe kakhulu futhi obusebenza kahle obusetshenziswe kabanzi emikhakheni eyahlukahlukene, okuhlanganisa ukukhiqizwa kwezimoto, izindiza, ukwakha imikhumbi, imishini kagesi, amadivayisi ezokwelapha, nokuningi.
Ngokuthuthuka kobuchwepheshe be-laser, ukushisela nge-laser kuye kwasetshenziswa nasemikhakheni yamadivayisi angangeni moya kanye nokwelashwa kokushisa kwamapuleti apholiswe ngamanzi (amapuleti apholiswe ngoketshezi). Uma kuqhathaniswa nokushisela nge-friction stir (FSW) kanye ne-vacuum brazing, inezinzuzo zokusebenza kahle kakhulu, ubuhlalu be-weld obubushelelezi nobuyisicaba, ivolumu yomsebenzi ephansi ngemva kokushisela, ukungena kwe-weld okuzinzile, kanye nekhono lokufeza ukushisela okunembile.
Amapuleti apholile ngamanzi amancane kakhulu, amapuleti apholile ngoketshezi emojuli yebhethri, iziteshi zamanzi zamapuleti apholile ngamanzi, kanye namapuleti apholile ngamanzi anesimo esikhethekile, njll., kusetshenziswa ubuchwepheshe bokushisela nge-laser, konke kungabonakala kalula.
4. Izinzuzo Zokushisela Nge-Laser

5. I-Mavenlaser igxile ekukhiqizweni kokushisela kwama-heat sink okupholisa uketshezi olufana ne-cold plate. Ibonisa amandla obuchwepheshe aqinile kanye nokuncintisana emakethe emkhakheni wokushisela umoya wama-energy storage plate, ama-liquid cooling plate, nama-water cooling plate. Ngokuphathelene nezinselele zokushisela zezinto zensimbi ezibonisa ukukhanya okuphezulu njengethusi ne-aluminium, i-Xinhe Xin Laser isebenzisa ubuchwepheshe bendawo yokukhanya efana nendandatho ehlanganiswe nendawo ephakathi elungisekayo. Ngohlelo lokulawula oluthuthukisiwe, ithuthukisa ngokufanele amapharamitha enqubo, inciphisa ngempumelelo ukuchitheka kwe-welding, ngaphandle kokukhiqiza ama-pores noma imifantu, futhi iqinisekise umthungo omuhle we-weld onekhwalithi ephezulu. Lokhu kuqinisekisa ngempumelelo ukungabi nomoya kwama-heat sink okupholisa uketshezi olufana ne-cold plate.
6. Ubunzima Ekushiseni I-Aluminium Alloy
I-Aluminium ithambekele kakhulu ekuqhekekeni kwe-hydrogen, okuholela ekwakhekeni kwama-bubble, okuthinta amandla kanye nezikhala zomoya.
I-Aluminium nayo ithambekele ekungcolisweni, futhi ungqimba lwe-oxide lunezinga eliphezulu lokuncibilika, okubangela kalula ukuchitheka kwe-welding.
I-coefficient yokwandisa i-aluminium inkulu, okwenza ithambekele ekuguqukeni, ekuqhekekeni, nasekucindezelekeni okuphezulu.
Izinto ezibonisa ukukhanya okuphezulu, ngesilinganiso sokukhanya kwe-laser esifinyelela ku-95% ekushiseni kwegumbi.
Indawo yokushisela ethinteke ekushiseni inkulu, ithinta amandla ezinto eziyisisekelo.
I-fiber optic emsulwa: Kuzoba nokuchitheka okwengeziwe uma kunamabhamuza.

Indawo yokukhanya efana nendandatho: Isilinganiso samandla sendandatho eyinhloko siyahlukahluka, futhi kunezilinganiso zamandla ezihambisanayo zezinhlobo ezahlukene zamaphrofayili e-aluminium.
Umthungo wokushisela udinga ukuhlanzeka: Uma kukhona amabala kawoyela kanye nokungcola, ukuchitheka kwenhlabathi kuvame ukwenzeka.
7. Indawo Yokukhanya Enesimo Sendandatho + Iphuzu Eliphakathi ElilungisekayoUbuchwepheshe be-Laser
Lobu buchwepheshe bungabhekana nezinselele zokushisela insimbi okukhanyayo kakhulu.
Ngesikhathi sokuthuthuka kwe-laser, indawo yokukhanya efana nendandatho idlala indima ekufudumaleni kwangaphambilini nasekupholiseni kancane, inciphise ngempumelelo ukuchitheka futhi ikhuthaze ukuxoshwa kwegesi ekhiqizwa umphumela we-keyhole.
8. Ukuqhathanisa i-metallographic yokushisela
Enkambisweni yokushisela nge-laser, lapho okokufaka ukushisa kuphezulu kakhulu, izinga lokushisa lendawo yokushisela nge-aluminium alloy lizokhula, futhi ukucindezeleka kokushisa kuzoba kubi kakhulu ngezinga eliphezulu kakhulu, okulula ukukudala imifantu. Ngakho-ke, ukulawulwa okufanele kwamapharamitha okushisela kuzosiza ekugwemeni ukufakwa kokushisa ngokweqile.
Umshini wokushisela we-laser we-Maven unokuqina okuhle kakhulu, ungafinyelela ukushisela okusheshayo, unciphise ukuchaphaza kwenhlansi, imikhiqizo ehlanganisiwe engenama-porosity, akukho mgodi wesihlabathi, akukho mhubhe, ukuguqulwa okuncane, ukushisela okubushelelezi nokuhle, ukuqinisekisa ukuthi imikhiqizo yokushisela iyathamba futhi iqine, asikho isidingo sokukhathazeka ngezinkinga zekhwalithi.
9..Inqubo yokwakha imbobo yokhiye nge-laser welding
10. Isixazululo kanye nezici
Ngokusebenzisa ubuchwepheshe be-annular light spot, amaphutha anjengemifantu nama-pores ancishiswa kakhulu, afinyelele ezingeni likazwelonke (GB/T 22085) B-level standard. Umthungo wokushisela unokumelana okuhle nokucindezela kanye nokuqina kokukhathala.
Ukusebenza kahle kokushisela kuphezulu, ukusetshenziswa kwamandla kwemishini kuphansi, futhi kunobungani nemvelo.
Amandla omugqa wokushisela aphezulu futhi indawo ethintekile ekushiseni kokushisela incane, kanti umthungo wokushisela unokubukeka okubushelelezi nokuhle.
Ilawulwa ngokuzenzakalelayo, ayisebenzi ekucubunguleni, futhi izinzile kakhulu.
Inqubo yokushisela amapuleti apholile ngamanzi
Akukho zimbobo zomoya, akukho ukuvuza, ukuguquguquka okuncane, imithungo yokushisela ebushelelezi kanye nekhwalithi enhle kakhulu.
11. Izinzuzo Zobuchwepheshe Bokushisela
