Laser welding aluminium alloy iingcebiso intshayelelo

I-aluminiyam ialloy ineenzuzo zokuxinana okuphantsi, amandla aphezulu kunye nokuxhathisa okulungileyo kokuhlwa, ngoko isetyenziswa ngokubanzi kumashishini eemoto, amandla amatsha, i-aerospace kunye neshishini lokwakha.Okwangoku, i-laser welding isetyenziswe ngokubanzi kwimveliso kunye nokuveliswa kweemveliso ze-aluminium alloy.Xa kuthelekiswa nendlela yokuwelda yemveli, i-laser welding inokubonelela ngokusebenza okuphezulu kwemveliso, umgangatho ongcono we-weld, kunye nokuqaphela ukuwelda okuchanekileyo kunye nokuzenzekelayo kwezakhiwo ezinzima.

Ukuwelda ngelaser bubuchwephesha obusasaza ubunzulu belaser kumphezulu wesinyithi, inyibilikisa isinyithi emva koko iyipholise kwaye iyikristale ukuze yenze i-weld ngokudityaniswa kwe-thermal phakathi kwelaser nentsimbi.Ngokwendlela yokusebenza ye-thermal ye-laser welding, inokwahlulwa ibe ziindidi ezimbini: i-thermal conductive welding kunye ne-welding yokungena enzulu.I-Thermal conductive welding isetyenziselwa ukupakisha i-welding yeendawo ezichanekileyo okanye i-micro-nano welding.I-laser ye-welding ye-deep penetration isetyenziswa kakhulu ekudibaniseni izinto ezifuna ukungena ngokupheleleyo.Inkqubo ye-welding iya kwenza ukuba izinto zibe ngumphunga, kwaye i-keyhole phenomenon iya kubonakala kwi-pool etyhidiweyo.Yeyona ndlela isetyenziswa kakhulu ngelaser welding ngoku, kwaye ikwayeyona ndlela ikhethwayo yokuwelda ialluminiyam.
