Aluminium alloy yeeb nkab yog cov khoom siv hlau, uas yog alloyed los ntawm txhuas thiab lwm yam hlau, uas muaj qhov zoo ntawm lub teeb yuag, siab zog, thiab corrosion kuj. Muaj coob tus neeg xav tias aluminium alloy tubes nyuaj rau welding, qhov no yog vim hais tias txhuas muaj ib tug tsawg melting point thiab siab thermal conductivity, uas yog nquag tsim oxide zaj duab xis thaum lub sij hawm vuam txheej txheem, uas cuam tshuam rau vuam zoo. Tab sis qhov tseeb, tsuav yog koj paub qhov tseeb welding txoj kev thiab kev txawj ntse, aluminium alloy kav yuav welded.
