I-aluminium alloy ineengenelo zokuba yi-low density, amandla aphezulu kunye nokumelana nokugqwala okuhle, ngoko ke isetyenziswa kakhulu kwishishini leemoto, amandla amatsha, i-aerospace kunye neshishini lokwakha. Okwangoku, i-laser welding isetyenziswa kakhulu kwimveliso nakwimveliso yeemveliso ze-aluminium alloy. Xa kuthelekiswa nendlela yendabuko yokuwelda, i-laser welding inokubonelela ngempumelelo ephezulu yemveliso, umgangatho ongcono wokuwelda, kwaye ifezekise ukuwelda okuchanekileyo kunye nokuzisebenzela ngokuzenzekelayo kwezakhiwo ezintsonkothileyo.
Ukuwelda nge-laser bubuchwepheshe obukhupha i-laser enamandla aphezulu phezu komphezulu wesinyithi, bunyibilikise isinyithi emva koko buphole kwaye buyikristle ukuze kwenze i-weld ngokusebenzisa i-thermal coupling phakathi kwe-laser kunye nesinyithi. Ngokwendlela yokusebenza kwe-thermal ye-laser welding, inokwahlulwa ibe ziintlobo ezimbini: ukuwelda okuqhubayo ngobushushu kunye nokuwelda okunzulu. Ukuwelda okuqhubayo ngobushushu kusetyenziswa kakhulu ekupakisheni ukuwelda kwamacandelo achanekileyo okanye ukuwelda kwe-micro-nano. Ukuwelda okunzulu kokungena nge-laser kusetyenziswa kakhulu ekuwelda kwezinto ezifuna ukungena ngokupheleleyo. Inkqubo yokuwelda iya kwenza ukuba izinto zibe ngumphunga, kwaye i-keyhole phenomenon iya kuvela echibini elinyibilikisiweyo. Yeyona ndlela yokuwelda nge-laser esetyenziswa kakhulu okwangoku, kwaye ikwayindlela ekhethwayo yokuwelda nge-aluminium alloy.
