Kubudirira kuri kuramba kuchiitika musimba idzva rebhatiri tekinoroji, zvichitungamira mukushanduka kwezvinodiwa zvebhatiri zvimiro zvezvikamu.Parizvino, vazhinji vanogadzira mabhatiri e-lithium vari kubatanidza mitsetse yemhangura pamitsetse yealuminium inobatanidza magetsi ebhatiri.Munzira dzechinyakare dzekugadzira, welding inoshanda pakati pemhangura nealuminium mitsetse inotadziswa nekushomeka kwezvinhu, zvingave zvichikonzera kusabudirira kwewelding, kusakwana kwesimba rekushongedza, kana kudhura zvakanyanya.
Kuti zvizadzise zvinodiwa nevatengi uye pamusika, timu yehunyanzvi kuDongguan Mares yakashandisa michina yekuparadzira mamorekuru kuwana welding pakati pealuminium nemhangura mitsetse.Mhedzisiro yewelding inoratidzwa mumufananidzo uri pamusoro: kutaridzika kwakanaka, weld seam idiki, uye simba rekudhonza rakakwirira.Ichi chigadzirwa chakagamuchirwa uye chakazivikanwa nevakawanda matinji emagetsi mabhatiri vatengi.
Molecular diffusion welding tekinoroji inoratidza mibairo yakanaka kana ikaiswa kune akawanda masimbi masimbi, kunyanya mumasimbi ekuwelda ane yakakwira yekupisa conductivity yakaita sealuminium, aruminiyamu alloys, uye mhangura, kuve nechokwadi chemhando yepamusoro uye kuvimbika.
Welding pakati pemhangura nealuminium mitsetse inonyanya kukodzera kutarisana kumeso.Nekuda kwealuminum's high reactivity, inowanzoita oxidation panguva yewelding process.Naizvozvo, kunyatso kudzora tembiricha yewelding uye nguva yakakosha kudzivirira kukanganisa kwemhangura-aluminium mitsetse.
Pre-welding Kuchenesa:
Usati waita diffusion welding, maworkpieces ane mavara emafuta pamusoro pemhangura-aluminium mitsetse inofanirwa kucheneswa ne organic solvents kana organic solvent vapor (senge acetone).Iyo oxide layer mukati meiyo 10mm yenzvimbo yewelding inofanira kunyatsocheneswa uchishandisa metallographic sandpaper kana emery mafaera, kunyanya mukati mukati mejoinhi.
Welding process:
Kuchengetedza kurongeka kwakafanana kwemhangura-aluminium strip workpieces munzvimbo yakakodzera mukati meiyo molecular diffusion process kwakakosha kuti uve nechokwadi chekuita chaiko.Izvi zvinogona kuwanikwa kuburikidza nekuisa zvigadziriso, kana nerubatsiro rwezvimwe zvigadziriso.Kuverenga tembiricha yewelding uye kubata nguva yekumanikidza zvichienderana nekukora kwewelding uye nzvimbo yekubata yemhangura nealuminium mitsetse kwakakosha kudzivirira zvinhu zvemhando senge thermal deformation.
